Warnings and Safety Information
Service and repair work should only be carried out by suitably qualified persons in accordance with all appropriate local and national safety regulations.
Before any service work is started, the appliance must be disconnected from the power supply.
If it is necessary to tip the machine when working on the lower areas, it may only be tilted onto its back. On models with salt container in the sump, the following must be performed:
Empty the water inlet mixer: Open the salt container cap briefly, reinstall the cap and ensure it is firmly secured. Any remaining water should then be removed from the cabinet. Upon completion of any service procedures, a short wash program without load should be run. This is to remove any salt residues that might be present and prevent possible corrosion.
If the retaining nut to the salt container becomes loose during repair work, the salt container can slip out of the connection to the water inlet mixer. Should this occur the salt container must be dismantled. To avoid leaks and additional procedures ensure the salt container is supported via the service opening.
Do not tilt the unit onto its right side, as this would cause water to run into the fan.
Many procedures will require the machine to be placed on its back. Care should be taken to avoid damage to the water hoses and power cord.
For questions, concerns, clarifications or further assistance contact the Miele Technical Support Center at 1-800-999-1360.

4.2 Water Intake
4.2.1 WaterProof System (WPS)
The Water Inlet Valve (Y2) consists of two (2) electro-mechanical valves mounted within a waterproof box located at the water connection (end of the water intake hose).
The valves are mounted in physically and electrically in series to ensure that if one valve should fail (e.g. due to blockage caused by a foreign body) the water flow will still be switched off by the other valve.
Figure 4-2: WaterProof System Intake Valves
G1000 / G2000 Dishwashers
30
Page 31
G1000 / G2000 Dishwashers
The WaterProof System (WPS) consists of a number of interdependent safety features, which provide protection against water leakage.
1. Protection against solenoid valve leakage:
Each water intake is controlled by an inlet valve. If this valve cannot close properly due to some defect or blockage by a foreign body, a second inlet valve ensures that the water supply is shut off.
2. Protection against water intake hose leakage:
If a leakage occurs, water flows along an outer hose sleeve surrounding the intake hose to the drip tray. Here a float switch then acts to switch off a micro­switch, which closes the inlet valves to cut off the water supply.
3. Protection against dishwasher overflow:
If some defect has caused the water level in the appliance to rise so that it overflows into the drip tray, and the water quantity sensor has also failed, the float switch is activated. This switches off a micro- switch, which closes the inlet valves to cut off the water supply. At the same time the drain pump is activated.
4. Protection against drain pump failure or blocked drain path:
In this case the water level in the appliance rises until it overflows into the drip tray where the float switch is activated. This switches off a micro-switch, which closes the inlet valves to cut off the water supply.
Warning
If the WaterProof System (WPS) is replaced, always ensure the correct flow restrictor is installed.

4.2.3 Water Inlet Mixer
Water is taken into the appliance via the inlet valve and the water inlet mixer, through the ion exchanger (water softener) into the sump. The water softener resin (for reactivation) is located at the bottom of the water inlet mixer. The assembly also contains the EGS valve (for the electronically controlled water softener) reactivation valve and a built in flow meter. The spray arm sensors are also positioned within the assembly (on appropriate models that include spray arm sensors).

4.2.7 Flow Meter B3/4, Water Intake Quantity
A Flow Meter B3/4 integrated in the Water Inlet Mixer monitors the water intake quantity. The water flow is measured in the hard water area.
A permanent magnet located in the Flow Meter axle activates an external reed switch each time the axle rotates. The pulses supplied by the reed switch are registered by the electronic unit and compared with a target value stored in memory for the particular program or program step in operation. For each liter of water, approx. 200 pulses should be registered. When the target value (maximum number of pulses) is reached, the water intake step is stopped. If the target value has not been reached after 4 min, the program is interrupted and the Drain Pump operates. Then, depending on the model, the Inlet/Drain LED flashes or fault code F13 is displayed, see Fault code F13, 6.8.14.
Note
For precise details regarding permissible minimum flow pressure, see the appropriate operating/installation instructions.
4.2.8 Sensor Softener
If there is a break in data transfer between the Sensor Softener and the electronic module, the control activates an emergency program. The basis for calculating the period between individual reactivation cycles is then the most recently registered water hardness Figure saved before the break in communications. At every new program start, the electronic module attempts to re-establish contact with the Sensor Softener. If this is successful, measured values from the Sensor Softener will then be used again.
To ensure that possible measurement faults at the Sensor Softener do not have severe consequences, the electronic control includes a further safety feature. A table relating water hardness to maximum water quantities is stored in memory. If the maximum water quantity for the hardness level in question is taken in without reactivation having taken place, a reactivation cycle is started automatically.
If a sensor softener fault is registered, the fault code F87 is displayed and saved in the fault memory, see Fault code F87, 6.8.15.
38
Page 39
G1000 / G2000 Dishwashers
4.2.9 Electronically Controlled Water Hardness (EGS)
To prevent or avoid possible glass corrosion, the wash water hardness level should not exceed or fall below 3 gr/gal, in program steps with heating and 5 gr/gal in program steps without heating. With mains water hardness below 20 gr/gal. (In heating steps under 16 gr/gal) the Solenoid Valve Y5 is activated to add a proportion of hard mains water to the cabinet. The proportion added in this way depends on the mains water hardness level set at the electronic unit or that measured at the Sensor Softener. The EGS system is not active as standard in all wash programs, but this can be programmed as an option if required.
The EGS Valve is located in the Water Inlet Mixer.
4.2.10 Intelligent Tab Function
To optimize wash results, the type of detergent (normal detergent or combination products in tablet form) used in the dishwasher can be set. To adjust the program sequence to suit the detergent type, press the Tab as appropriate. The selected function remains applicable until it is modified again. It is therefore not necessary to select 2 in 1 or 3 in 1 before every program.
Standard detergent (powder or tab form): The tab button is not pressed. This means filling rinse aid in the customary way, and salt will be consumed for the reactivation of the water softener.
2 in 1 Detergent: When the 2 in 1 function is selected, the program sequence is adjusted for 2 in 1 tablets (containing detergent and rinse aid). All water intake will be with soft water at the pre-set water hardness level. The dispensing of rinse aid and the rinse aid refill indicator light are deactivated.
3 in 1 Detergent: When 3 in 1 function is selected, the program sequence is adjusted for 3 in 1 tablets (containing detergent, rinse aid and salt). The dispensing of rinse aid and the rinse aid refill indicator light are deactivated. Salt consumption for the softener reactivation is reduced to between 1/3 and ¼ of its normal level. During the first two water intake cycles, prepared water taken from the water softener is added to the circulating water. During the following intake cycle, the softener is inactive.
Technical Information
39
Page 40
Note
When selecting the function “2in1” or “3in1”, impulses dispense rinse aid (1 ml), to slowly empty the dispensing chamber. This is necessary since rinse aid remnants, depending on their chemical composition, can clump, or separate, under certain temperature and storage conditions. The additional rinse aid dispensed as the chamber is being emptied has a positive effect on the drying result. So if the drying result deteriorates after some time of washing with combination products, it might be that all rinse aid remnants have been flushed from the detergent chamber.
Warning
The 3 in 1 function may not be selected if the water hardness level is above 26 gr/gal. The detergent manufacturer’s instructions must be followed.
Note
If detergent tabs are used which contain other components in addition to rinse aid and salt replacement (such as glass care, stainless steel shine, etc.), select function “3in1”.

Water is passed to the spray arms via the circulation pump. There are two circulation pump versions depending on model.
Circulation pump with slide shutter: MPEW (approx. 65 W) With spray arm alternation, the spray arms are only intermittently supplied with water. This is achieved via a slide shutter, which is moved back and forth as appropriate to open or close water paths to the different spray arms. For 30 sec. both the top and bottom spray arms are supplied and during the next 30 sec. the middle spray arm only. The total water circulation rate is constant and is approx. 34 l/min. Detergent is only dispensed when the middle spray arm is being supplied with water.
A hall sensor is located between the pump housing and the motor to measure the pump speed. Depending on the measured value, the quantity of additional water required, if any, can be established.
G1000 / G2000 Dishwashers

G1000 / G2000 Dishwashers
Circulation pump without slide shutter: MPEH (approx. 85 W) With the circulation pump without the slide shutter, all three spray arms are supplied with water at the same time. The total water circulation rate is approx. 68 l/min. Approx. 15 l/min flow through the top spray arm, approx. 34 l/min through the middle spray arm and approx. 19 l/min through the bottom spray arm. This pump version does not have a speed sensor.
Both pumps are equipped with a winding changeover, which increases the torque at the moment they are switched on (higher starting torque). In this state the main winding is connected directly, and the auxiliary winding connected indirectly via the capacitor, to the power supply.
The winding changes are made via a changeover relay on the electronic module. At every switch-on, the changeover relay and the circulation pump-starting relay are supplied with power at the same time. The changeover relay switches the windings with a time delay.
Both circulation pumps have thermal winding protection.
4.3.2 Circulation Pump - Speed Sensor and Load Sensing
G1570 SC VI, G2570 SC VI G2630 SCI, G2670 SCVI, G2830 SCI
The MPEW circulation pump (with slide shutter) is fitted with a speed sensor (Hall Sensor), which is located between the pump housing and motor. The pump speed can be measured via the sensor and a ring magnet mounted on the circulation pump shaft.
The quantity of water taken in at the start of the program is measured via the flow meter, B3/4. This basic quantity of water wets the load and settles in certain areas such as on the bottom of cups. The lower the quantity of water that flows back into the sump, the greater the quantity of dishes in the appliance, as more water has been required to wet the load. The way the circulation pump is running is used to register how much water has flowed back to the sump. If sufficient water has returned, the pump runs evenly. With too little water, the pump speed fluctuates. Using this feature, additional small quantities of water are taken in until a stable motor speed is registered.
By monitoring the speed in this way and thus controlling additional water intake precisely can reduce energy and water consumption. The potential savings are approx. 15% water and 19% energy.

G1000 / G2000 Dishwashers
Note
This system has an additional advantage. Good wash results are also ensured if the dishwasher load includes items with less than ideal shape (e.g. cups with deep bases) as the controlled additional water intake will replace the water that may be trapped in such pieces. This similarly applies if, e.g., a light plastic bowl should be turned over and filled inadvertently by the stream of water.

4.3.3 Heating
A ring heater element in the circulation pump housing heats the water. The heater element and circulation pump together form one component. This ensures that on models with spray arm alternation, heating can always be carried out whichever water path is currently being used.
Integrating the heater element in the pump housing also ensures that it is always cooled sufficiently thus preventing the baking-on of soil particles or impurities in the water.
Various safety measures protect the heater element against overheating, such as the following:
Heater Pressure Switch NTC Temperature Sensor Electronic Control
The heater is only activated when the circulation pump has taken in sufficient water.
4.3.4 NTC Temperature Sensor, R30
An NTC sensor is fitted in the sump and monitors water temperatures during dishwashing.
If the maximum safety temperature of 194° F at the NTC sensor is exceeded, the program is interrupted (boiling prevention) and fault code F26 is registered, see Fault code F26, 6.8.15.
If during heating the desired temperature is not reached in the given time, a fault is registered, see F25, 6.8.12.
If the sensor or its connections are open- or short-circuited, the heating is switched off. The program then continues to the end without heating or dispensing, see Fault code F01, (NTC short-circuited), 6.3.12 or Fault code F02, 6.8.12.

4.3.5 Heater Pressure Switch, B1/13
The heater pressure switch B1/13 is located directly on the circulation pump and registers the water pressure when the pump is in operation.
Using the pressure switch contacts, the heating is controlled via 2 poles. The heating is switched via a heating relay located before the pressure switch contacts in the circuit. Heating activation occurs during the wash and final rinse cycles.
If the circulation pump and heating relay are activated and the heater pressure switch reset contact is open, the control registers a water intake fault, see Fault code F14, 6.8.15.

4.3.6 Turbidity Sensor (ECO Sensor III, Auto-sensor), B3/10
Dishwashers from the G 1000/G 2000 generation are provided with one of two turbidity sensors, depending on model:
The ECO sensor III measures the turbidity of the water and based on this result, the wash blocks, temperatures and running times of automatic programs are modified. In addition to this, the Auto-sensor has a microprocessor to evaluate the particle measurement.
Principle of Operation Water circulation and the presence of detergent cause bubbles to develop and measurement technology cannot differentiate between such bubbles and suspended soil particles. With the ECO sensor a proportion of the suds is directed into a bypass channel, which is wider at the other end. This causes the flow rate to reduce and hence the bubbles in the water to rise. The suspended soil particles in the water can then be more accurately registered in the following measuring process.
A photoelectric barrier switch (IR diode (infrared) opposite a photo transistor) acts as a turbidity sensor. Depending on the turbidity (Transparency) of the water, a certain current flows through the phototransistor. This current is measured and processed by the electronic unit, which then initiates the appropriate action. If the level of turbidity passes certain thresholds, then depending on the soiling detected, the following cleaning cycles are modified accordingly with regard to water quantity, program duration and temperature.

Page 49
G1000 / G2000 Dishwashers
Figure 4-13: Turbidity Sensor
The sensor is situated in the feed pipe to the top spray arm, as shown in Figure 4-13.
The flow rate is approx. 15 l/min. In order to compensate for residues on the sensor and ageing of the optical system, the turbidity sensor must be recalibrated regularly. This process is carried out automatically by the electronic unit and cannot be modified in any way. Measurements are carried out at different times during the pre­wash, main wash and interim rinse stages. For this, the top and bottom spray arms must be supplied with water.

4.3.7 Spray Arm Sensing
Specific model dishwashers are equipped with a spray arm sensing system to alert
the operator that the spray arm is obstructed by a large dish, or utensil etc....
A spray arm sensor(s) is / are fitted on the water intake to monitor the middle and / or lower spray arm(s) as shown in Figure 4-14. A small magnet is fitted on one end of the appropriate spray arm.
Figure 4-14: Spray Arm Sensor
The spray arm sensor is only monitored during a program in operation when the circulation pump is activated.
The time period during which the spray arms are monitored is given by the electronic control. If a fault is detected, it will be indicated but not saved in the fault memory. The indication will be cancelled when the fault is remedied.
The minimum spray arm speed is approx. 5 rpm. Therefore approx. 12 sec. after the start of the monitoring time, the next pulse should be registered.
The maximum spray arm speed is approx. 50rpm. Therefore after the start of the monitoring time, the next pulse can only be registered at the earliest approx. 1.2 sec. later.
If a fault is indicated, the indication will remain active even after the door has been opened. To cancel the fault indication, the door must be closed again.

4.3.8 Filter Combination with Micro Fine Filter
1 Crown Coarse Filter 2 Large Surface Area Fine Filter 3 Micro Fine Filter 4 Filter Cap
Figure 4-15: Filter Combination in Sump
The circulation pump M6 pumps the wash water from the sump via the filter combination to the spray arms. The circulating wash water is filtered via 2 parallel paths. A proportion of the water flows through the central opening of the crown coarse filter and then passes through the conical micro fine filter; see Figure 4-15, Item 3. The remainder passes directly through the large surface area fine filter; see Figure 4-15, Item 2, which has a small additional hole to provide a vent for the circulation pump intake area. All water is then mixed together again in the sump where it is taken in by the circulation pump and the circuit is repeated. In this way some of the water passing through the filter system always passes through the micro fine filter so the proportion of soil particles in the suds is continually being reduced. Soil that is retained by the micro fine filter either collects there or falls onto the filter cap where it will eventually be removed by the drain pump.
The crown coarse filter, see Figure 4-15, Item 1, is attached to the filter combination handle. If dispensed powder detergent should fall into the micro fine filter, it remains on the filter cap where it can dissolve, instead of collecting in the drain outlet. Foreign bodies, which pass the crown coarse filter to the micro fine filter collect on the filter cap and so cannot block the drain outlet.

4.4 Dispensing
4.4.1 Combination Dispenser
1 Reed Switch 2 Solenoid
Figure 4-16: Combination Dispenser
The dispenser contains a solenoid that is activated via pulses to dispense detergent and rinse aid. The first pulse opens the detergent dispenser flap. All following pulses then dispense rinse aid.
During detergent dispensing the solenoid is activated by a brief pulse, and this opens the detergent dispenser flap.
Rinse aid is dispensed in pulses. Each solenoid impulse dispenses approx. 1 ml rinse aid into the cabinet interior. 3 solenoid pulses are therefore required to dispense the normal quantity of rinse aid of 3 ml per wash. Each pulse is applied for approx. 10 sec. so that there is sufficient time for the rinse aid to flow into the cabinet. The pause between individual pulses is also approx. 10 sec.
If the rinse aid container is empty, a reed switch is activated and this lights up an LED in the control panel or display. The rinse aid container has a capacity of 110 ml.

4.5 Drain System
4.5.1 Drain Pump
The drain pump M8 is driven by a synchronous motor and located under the cabinet on the left next to the sump. It is directly activated by the electronic module. In case of fault, the drain pump M8 is also activated directly via the overflow float switch B8/3. The drain pump pumps the suds via the non-return valve and the drain hose to the on-site drain.
During drainage the drain pump M8 extracts water from below the microfine filter. This reverses the direction of flow through the microfine filter that normally exists during the cleaning and rinse cycles. Soil particles that have been trapped in the filter during dishwashing are then flushed out with the drain water.
Pumping limits: Max. 13’ hose length Max. 3’ 3” head height
Most faults will cause the program in operation to be interrupted and the drain pump to start.
If the WaterProof System has been activated, Fault code F70, 6.8.15, the drain pump continues to operate even after the appliance has been switched off. In this case, the pump is only switched off when the power source is disconnected.

4.6 Drying
Depending on model and production time frame, the G1xxx/G2xxx series dishwashers are outlined below:
4.6.1 Circulation Turbothermic Drying (active): UTT Version 1
1 Inner Fan Channel 2 Outer Fan Channel 3 Fan
Figure 4-17: Drying System UTT Version 1
54
Page 55
G1000 / G2000 Dishwashers
Circulation Turbothermic drying (UTT) operates with two separate air paths:
Condensing Circuit To get dishes dry, moisture has to be removed from the dishwasher cabinet. The moist, warm air in the cabinet is gradually cooled. Cold air can hold less moisture than warm air, and thus, in this cooling process condensation drops form, which settle in the coldest areas of this circuit. To remove moisture from the air in the dishwasher cabinet, the air is sucked in above the cutlery tray (right front) and channeled into a condensing pocket. This condensing pocket is located in the right outer wall of the dishwasher with cool ambient air circulating around it, which results in a faster cooling of the moist, warm air in the dishwasher cabinet. To enhance the heat dissipation, the side panels are made of a thin (0.1 mm) stainless steel foil. The de-humidified air and the condensation go back into the dishwasher cabinet via the round opening at the side. The condensation (maximum ½ water glass) collects in the sump, and the air continues circulating. At the end of the program, the condensation is drained off.
Cooling Circuit With Ambient Air To cool off the warm air in the cabinet, cold or cooler air is needed. To this end, ambient air is sucked in at the front bottom area and channeled past the sides of the condenser. These are the areas between condenser and the outside wall of the dishwasher, and between the condenser and the dishwasher cabinet wall. The air is then passed back into the room at the top rear wall. The effect is an efficient heat transfer, turning the warm air into cooler air and removing more and more moisture from the air in the cabinet, thereby drying the dishes effectively.
The clear separation of ambient air and dishwasher cabinet air has the following advantages:
Independent of the type of water connection (cold or hot water) a good drying result is achieved.
By clearly separating the condensation and cooling circuit, air discharge at the front panel is eliminated. The inside air remains completely inside the dishwasher cabinet.

4.6.2 Circulation Turbothermic Drying (active): UTT Version 2
Note
This system is installed in models Gx04x – Gx47x starting with production index 34/…
Figure 4-18: Drying System UTT Version 2
The function of both versions of circulation Turbothermic drying is comparable. However, Version 2 has no condenser pocket. Therefore the dishwashing cabinet is completely closed – the openings, to which the condenser pocket is attached in Version 1, are eliminated.
As a result, the entire area of the right side panel is cooled by the fan. The moist, warm cabinet air settles in the coldest areas of the cooling circuit and condenses on the cool cabinet inside wall. Moisture is removed from the cabinet, and the dishes dry through the residual heat. The condensation runs down the cabinet inside wall to the sump and is pumped off at the end of the program.
56
Page 57
G1000 / G2000 Dishwashers
4.6.3 Fan
Two different fan types are employed for the two different versions of circulation Turbothermic drying:
Circulation Turbothermic drying (active): UTT Version 1 A split-pole motor (approx. 23 W) drives two impellers. One impeller directs cool air across the outer surface of the stainless-steel condensation surface foils. The second impeller transports steam from the cabinet to the condensation surfaces.
Circulation Turbothermic drying (active): UTT Version 2 A split-pole motor (approx. 19 W) drives an impeller, which transports cool air to the outer surface of the right side panel.
