TOP CLOSING

CONDITIONS FOR HOT WATER INTAKE

• Hot water intake from hot water valve is applicable at temperatures at 60

or higher.

• During hot water intake, if the machine is turned off and on, the water

should be filled through the cold water valve making level checks and without a motor movement.

• During hot water intakes, when the water temperature reaches (target

temperature - 5), the hot water valve should be shut off and continued with the cold water valve.

END

Top closure algorithm is not applied under following conditions:

 If previous programme is

cancelled and a new programme started, top closure algorithm is not applied in the newly selected programme.

1. Water intakes in all programmes are realized by water level sensor. Whether or not the water level has dropped below levels determined according to the steps is checked by the water level sensor. If the water level has dropped, water will be intaken against checking the the water level sensor.

2. Top closure algorithm is applied during programme startup.

Figure 7.2 Top closure algorithm

3. Later water intakes are realized according to the levels determined according to the programmes. If the selected programme temperature is 60C or higher than 60C, water intakes are made via hot water valve. Otherwise, water is taken through cold water valve.

4. Amount of load in the machine is determined according to number of valve opening in this step. Max. water intake number may change according to energy declaration target.

Depending on the low, medium or high load, washing parameters such

as heating step time, rinse water amount are changed.

5. When water level drops below Psafety (Pg) level in washing steps during and after heating, heater is turned off. Water is taken from the main wash valve.

Page 41

B13 B7S B7SLED WASHING MACHINE SERVICE HAND BOOK

7.2. Heating Profile

Hysteresis profile is used for all programmes. Information about the amount of hysteresis according to the programme is included in

the variable file. In programmes where there is risk of damaging textiles such as woolens or hand

wash, hysteresis value is maintained high. For this reason, heating profiles of these programmes can be seen as hysteresis. However, under bad conditions like very low water inlet temperature, hysteresis can be seen.

Figure 7.3 Graphic for heating with hysteresis Once the machine reaches the max. set temperature (Tset) for the machine, heater is

deactivated, but remains in heating step. When temperature drops in the amount determined in the software, (T) heater is

reactivated. This process goes on until the time designated for heating step is completed (tx). When heating profile with hysteresis is used, adverse affecting possibility of max.

reached temperature by the following is minimized:

 Input temperature of water lower than ambient temperature,  Low input voltage,  Excessive water intake by the machine,  Adding water from the detergent dispenser.

7.3. Anti-foaming Profile

Following profile is used to decrease foaming at the end of main wash:

Page 42

B13 B7S B7SLED WASHING MACHINE SERVICE HAND BOOK

 Discharge the water inside the machine after main washing step is finished. (If

additional water is taken without discharging water, foam overflow will occur.)

o Movement in discharging 80 rpm – 12 s on – 10 s off)

 Wait 2 sec.  Intake water by time. (10 s; may vary according to control systems.)  Wash for 5 min. in woolen washing percentage. (to extinguish foam)

o Movement 30 rpm – 3 s on – 80 s off)

 Discharge the water and continue with main wash end spin.

o Movement in discharging 80 rpm – 12 s on – 10 s off)

7.4. Foam Detecting and Extinguishing Algorithm

If foaming occurred in the machine is determined by water level check during spin; if foam occurred, profile is applied to extinguish and discharge.

 If the measured level is higher than the determined foam level;

o Motor is stopped for 280 s, (motionless waiting) o Water is taken for 4 s, o Motor is stopped for 30 s, (motionless waiting) o Psafety 4 + 6 s pumping performed. o Water is taken for 4 s, o Motor is stopped for 30 s, (motionless waiting) o Psafety 4 + 6 s pumping performed. o Water is taken for 4 s, o Motor is stopped for 30 s, (motionless waiting) o Psafety 4 + 6 s pumping performed. o Spinning starts again.

 This control is repeated 3 time in each spin.  If the foam level is still high at the end of all 3 trials, spin is skipped to switch to

the next step.  Extra rinse is determined according to the number of foam detecting.

o If 1-2-3, 1 rinse, o If 4-5, 2 rinses, o If more than 5, 3 rinses are added.

 If the foam level is still high after trying 3 times in the last spin step, programme is finished without spinning.

8. COMPONENT WORKING PRINCIPLES

8.1. Electronic Control and Visual Card

By means of the control and visual card which is designed to have a single face and manufactured by ARÇELİK; the wash programs which are written onto the microprocessor, washing and spinning motor profiles, protection algorithms and components (motor, heater, pump, valves, door safety lock, ntc, water level selection switch, spinning/temperature selection potentiometer) are controlled. There are feeding circuit on the front face of the card (smps), motor and other component control circuits -triac and relays - and component connection terminals and on its rear face there are microprocessor, function and time delay button and LEDs and program tracking LEDs. Necessary wash program is operated in line with the information read from the program selection switch which is connected to the card (rotary switch), spinning/temperature setting potentiometer, auxiliary function and Time Delay switches. From the card, auxiliary function, speed/temperature and time delay options and functions can be selected.

Rated Operating Voltage : 250V 50-60Hz Operating Current : 10-50 mA PTC Resistance : Min. >=50 ohm Contact Locking time : <=8s Contact Engaging time : 35...70s Operating Temperatures : T85

8.2. Safety Switch (Door Lock)

Picture 8.2 Safety switch PTC door safety lock was used. When any wash program is started after the door is

closed, PTC disk is heated and the door is locked and it is prevented to be opened when the program is in progress. After the program finishes, PTC cools down in 70s and the door is unlocked. Current of all components passes over the door safety lock. Machine will not work in case it is faulty. When 220V is supplied between the contacts numbered 3 and 1, the distance between the contacts numbered 3 and 2 should switch to closed position.

8.3. Motor Universal series motor is used. Universal series motor consists of stator and rotor. Stator and rotor windings are connected in series by means of collector and brush and current is transmitted to the rotor windings. Motor speed control is made over electronic card. Motor triac on the card adjusts the motor/drum speed by changing the triac triggering angle according to the signal coming from the tacho. In case of abnormal situations (continuous operation-locked rotor), thermocouple is available on the motor winding to protect the winding from overheating.

Rated Operating Voltage 220-240V 50-60Hz Current 6A max (washing) / 3A (spinning) Input Power 300 / 450 W Starting Current 5...8A (washing) / 10A max (spinning)

When the resistance is measured from both ends with multimeter, approx. 26 should be read.

Picture 8.3. Motor

8.4. Heater It is used to heat the water inside the drum. Since it is an electronically controlled machine, there is a double thermocouple at each of the heater inlets. When the heater operates dry, the overheated thermocouple open circuits the heater. Open circuited heater cannot be used again. In order to prevent the heater to

operate without water “during heating”, heater safety water level is defined to the

microprocessor (Psafety). When the water level which is measured by the water level sensor comes under the defined Psafety level, heater is disabled.

When the water temperature which is read by NTC reaches to the “selected

temperature”, heater is disabled by the microprocessor.

Picture 8.4 Heater

8.5. Valve There is 2-way valve in the models which have a single water inlet and there is 2-way valve and extra single valve in the hot-water inlet machines. Valves are driven by the triacs on the electronic board; and they are driven with both valves in the softener step by use of crashed water directing system and the water is directed to the medium compartment of the detergent dispenser. Rated Voltage 220-240 V 50/60 Hz Rated Power 5-8 W Winding Resistance 3400-4500 ohm Flow 10 l/min

8.6. Drain Pump

It is a synchronous motor equipped with a mono-phase bipolar magnet rotor. At the draining step, electronic control card is activated by the triac on it. It is protected by impedance for continuous operation and blocking situation of the rotor.

Drain pump drains the water inside the drum.

Resistance values which are read from the NTC ends by means of multimeter are compared to the below table. These approximate values should be read.

8.7. Ntc

It is a component which is used to measure the water temperature inside the drum and resistance of which decreases when the temperature increases.

When the water temperature reaches to the adjusted temperature, heater is disabled by means of the heater relay on the card.

Picture 8.6 NTC

Table 8.1 NTC values

8.8. Water Level Sensor

An analog water level sensor which is fed by 5 V voltage is used. This sensor ensures that the water level is determined instantly with the frequency values which it generates against the pressure created. There are frequency values corresponding to the all pressure values. An infinite number of levels can be determined in the analog water level sensor. Water levels change according to the wash criteria of the designed program depending on the selected program, temperature and auxiliary function. Analog water level sensors are pressure – displacement inverter components in general. Analog water level sensors generate frequency modulation as output.

Page 52

B13 B7S B7SLED WASHING MACHINE SERVICE HAND BOOK

Cable inputs 5VDC / Data / GND.

Operating Voltage : 5 VDC

When it is empty, 625 ± 2 Hz frequency value should

be read from the Data and GND terminals.

There are basically 2 capacitors, 1 coil and an inverter circuit on itself or the control system to which it is connected. Pressure increase pushes a ferrite part inside the sensor into the coil. Therefore L (inductance) value of coil winding changes and the output value of the sensor – inverter system changes. Therefore pressure value can be measured in an analog manner. The amount of water to be taken in for the programs is controlled by the water meters. Water level sensor serves the basic functions of deciding to take in water again, control the heater safety level, door opening level or foam level. Also, if there are any error in the water meters or its connections, water is taken in with the water level sensor.

9. SERVICE FUNCTION TEST

Following points should be paid attention to during service test:

 Entrance Method to Service Mode:

By pressing the “Start/Pause” button, you can switch to “Service” mode when you turn

the button to the first program from the rotary “ON/OFF” position CW.

 To activate the components which are controlled in each step of the service mode,

the door has to be mechanically locked, that is, components must be powered. For example, to rotate the motor, the door must be locked, in other words motor must be energized.  After the service mode is entered, if door contact is not closed for any reason (door lock is faulty or door lock triac is faulty), that is electronic card is energized but the driven components (heater, motor, pump, etc.) are not: a) In Models with LED: "Ready" follow up LED will be lit steadily. In the meantime, if EEPROM has a "Error Code", they will be coded at "Spin Level" LEDs (in decimal system (BCD format)). If there is no error, all of the "Spin Level" LEDs will be turned off. Also, if "Start/Pause" button is pressed, then no change will take place in the above mentioned issues and as the door is not locked in real "Service Mode" steps will not be progressed and "Error Code" will be shown steadily.  b) In 75 models : If you have an "Error Code" on EEPROM, this will be shown on 7S display as "E?" If there is no error, "E--" will be shown on 7S display. Also, if "Start/Pause" button is pressed, then no change will take place in the above mentioned issues and as the door is not locked in real "Service Mode" steps will not be progressed and "Error Code" will be shown steadily.

 If the energy of the machine is interrupted due to any reason whatsoever at any

stage of service test (due to “ON/OFF” or power cut), WM goes back to "Selection Mode"

when it is energized again. If more that 2 minutes are waited at a service test step, WM goes back to selection mode. At the service mode, components are activated one by one by pressing the Start/Pause button. In turn:

1) At startup, “Error Code” which is created last and recorded to EEPROM is shown. Following points should be paid attention when “Error Code” is displayed:

I) In 7S Models:

If there is an “Error Code”, counterpart of this code in the decimal system (in BCD format)

is displayed on 7S by adding “E” to the beginning. Example; “E09” or “E13”. If there is no “Error Code”, this is displayed on 7S as “E--”.

II. Only in Models with LED:

If there is an “Error Code”, counterpart of this code in the decimal system (in BCD format)

is encoded to the “Spin Level LEDS". When encoding is performed, weights of the orders

from the bottom to the top are as follows 20=1, 21=2, 22=4, 23=8 Hertz in turn. For example, if the "Error Code" is "03" then the bottom most 1st and 2nd LEDs will be turned on while others are turned off. If the "Error Code" is "08" then only the 4th LED from the bottom will be turned on while others are turned off.

Page 54

B13 B7S B7SLED WASHING MACHINE SERVICE HAND BOOK

If there is no "Error Code" then all LEDs should be turned off. Next step is taken by pressing the "Start/Pause" button;

2) "Error Code" and other information stored in EEPROM (point to resume) are deleted from EEPROM and in 7S models 3-digit software version is displayed, and to switch to the next step "Start/Pause" button is pressed; Only in Models with LEDs the next step will be automatically progressed (without pressing "Start/Pause" button).

3) By flashing all segments of 7S and all LEDs "Display" test is realized. When "Start/Pause" button is pressed, all segments of 7S and all LEDs are turned off to end "Display" test and switch to next step;

4) Turned for 52rpm to right (CW). Meanwhile, in 7S models, "4", which is the "service mode step number" of this step is displayed. In Models with LED, of the "Program Tracking LEDs" above the "Start/Pause" button, the 3rd LED from the bottom will be turned on (weight of orders from bottom to top are 20=1, 21=2, 22=4, 23=8, 24=16); Next step is taken by pressing the "Start/Standby" button;

5) Turned for 52rpm to left (CW). Meanwhile, in 7S models, "5", which is the "service mode step number" of this step is displayed. In Models with LED, of the "Program Tracking LEDs" above the "Start/Pause" button, the 1st and 3rd LED from the bottom will be turned on (weight of orders from bottom to top are 20=1, 21=2, 22=4, 23=8, 24=16); Next step is taken by pressing the "Start/Standby" button;

6) In the previous movement, motor movement is stopped and following checks were performed and tester was informed in different ways: If the Water Level Value read on the Water Level Sensor is out of the limits (if Water Level Sensor socket is properly fitted or if it is loose), next step "7" is taken. This way, there is not any drum movement in step 6 and if step 7 is taken automatically, person making the test will sense this condition as "Water Level Sensor Error" . b) although the Water Level Value read on the sensor is within the limits if it is above "Safety Level", pump is operated and when the level drops below the "Safety Level" basic controls of this step are carried out (meanwhile drain pump is active).

These are, in the order of priority;

I. If there is NTC error, 100rpm is applied; II. If there is no NTC error, but if the values read at Line Voltage Reading Inlets

(Line_Voltage_ADC) are below 185 Volts or above 265 Volts, 140 rpm is applied. This error could be caused by two conditions: Either the ADC inlets of microprocessor are defective or it is indeed out of the line voltage limits

III. If there is no any NTC error and no error on Line_Voltage_ADC inlets, “MAX_SPEED /

Meanwhile, "7", which is the service mode step number is displayed on screen of 7S Models;

In Models with LED, of the "Programme Tracking LEDs" above the "Start/Pause" button the 2nd and 3rd LEDs from the bottom will be turned on (weight of orders from bottom to top are 20=1, 21=2, 22= 4, 23 = 8, 24 = 16); Next test step is taken by pressing the "Start/Standby" button.

8) “PRE_WASH_VALVE” which is opened for test in the previous step is shut. “MAIN_WASH_VALVE” which is the main test of this step is opened and checked.

Meanwhile, "8", which is the service mode step number is displayed on screen of 7S Models; In Models with LED, of the "Programme Tracking LEDs" above the "Start/Pause" button the 2nd and 3rd LEDs from the bottom will be turned on (weight of orders from bottom to top are 20=1, 21=2, 22=4, 23= = 8, 24 = 16); Next test step is taken by pressing the "Start/Pause" button.

9) “MAIN_WASH_VALVE” which is opened for test in the previous step is shut. “SOFTENER_VALVE” which is the main test of this step is opened and checked.

Meanwhile, "9", which is the service mode step number is displayed on screen of 7S Models; In Models with LED, of the "Programme Tracking LEDs" above the "Start/Pause" button the 1st and 4th LEDs from the bottom will be turned on (weight of orders from bottom to top are 20=1, 21=2, 22= 4, 23 = 8, 24 =

16); Next test step is taken by pressing the "Start/Pause" button.

10) “SOFTENER_VALVE” which is opened for test in the previous step is shut. "HOT_WATER_VALVE" which is the basic test of this step is opened to check if available on the machine being tested (if no hot water valve is available, this step is automatically skipped"). Meanwhile, "10", which is the service mode step number is displayed on screen of 7S Models; In Models with LED, of the "Programme Tracking LEDs" above the "Start/Pause" button the 2nd and 4th LEDs from the bottom will be turned on (weight of orders from bottom to top are 20=1, 21=2, 22= 4, 23 = 8, 24 = 16); Next test step is taken by pressing the "Start/Pause" button.

11) “HOT_WATER_VALVE” which is opened for test in the previous step is shut. HEATER test which is the main test of this step is conducted as follows; If the Water Level Value read on the Water Level Sensor is out of the limits (if Water Level Sensor socket is properly fitted or if it is loose), next step "12" is taken. This way, if there is not any increase in power in step 11 in terms of washing machine consumption and if step 12 is taken automatically, person making the test will sense this condition as "Water Level Sensor Error". (Rev02_07102011):b) Although the Water Level Sensor readings are within limits if the water level is below "Safety_Level + 20 units" then all valves will be opened to top up the water level.When the water level exceeds "Safety Level + 20 units" the open valves will be shut off automatically. After this stage there are 2 conditions: i) On a machine without "Main Wash Flow Meter": HEATER is turned on automatically and 52rpm is applied to right. (With REV_04, 52 rpm to right at Heating step is removed.) Tester checks whether there is an increase in the

Page 56

B13 B7S B7SLED WASHING MACHINE SERVICE HAND BOOK

power which is consumed by WM and check heater.ii) On a machine with "Main Wash Flow Meter": "Main_Wash_Flow_Meter" will be checked to see if it is higher than "50" or not. If it is higher than 50, then Flow_Meter is operating correctly; HEATER will turn on automatically and a 52rpm right turn will be applied.(In models with flow meter, there is motor movement) If it is below 50, then the Flow_Meter is faulty and therefore the heater will not be "DRIVEN" and proceeded to the next step of the service mode ("step_12"). In this way Flow_Meter error will be identified. Meanwhile, "11", which is the service mode step number is displayed on screen of 7S Models; In Models with LED, of the "Programme Tracking LEDs" above the "Start/Pause" button the 1st, 2nd and 4th LEDs from the bottom will be turned on (weight of orders from bottom to top are 20=1, 21=2, 22= 4, 23 = 8, 24 = 16); Next test step is taken by pressing the "Start/Standby" button.

12) “HEATER” which is opened for test in the previous step is shut. Also, the motor movement which is started in the previous step is finalized and all valves are shut.

“PUMP” which is the main test of this step is opened and water inside the WM is drained below "Safety_Level". When the water level comes below “Security_Level”, pump is shut

off. At the beginning of the drain process, MAIN_WASH and HOT_WATER valves will be turned on for 5 seconds (Rev01_22072011) Meanwhile, "12", which is the service mode step number is displayed on screen of 7S Models; In Models with LED, of the "Programme Tracking LEDs" above the "Start/Pause" button the 3rd and 4th LEDs from the bottom will be turned on (weight of orders from bottom to top are 20=1, 21=2, 22= 4, 23 = 8, 24 = 16); "At the spinning stage, if no error, "turn at max/2 speed" "rule is modified as "turn at max speed" . The 52 RPM right turn movement at the heater stage is removed.

Since this step is the last stage of the service test, if the “Start/Pause” button is pressed

for one more time, this will return to step 1.

Explain the customer the

following Antifoam measures.

Reasons of foam creation and methods for preventing this,

1) If you add detergent in the prewash compartment although you have not selected a prewash cycle, detergent is taken from this compartment during rinsing the laundry which causes foam creation.

2)You should use laundry detergent in automatic washing machines.

3)Laundry may have detergent leftovers as a result of using excessive detergent. You should try to use only adequate amount of it.

4) Keep your detergent in a closed and dry place.

5) You should use less amount of detergent than ever for your lacy laundry.

6) You should not use too much softener.

Is there E18 error?

Yes

Explain the customer the

following unbalanced load

preventive actions.

Reasons for ending the program without spinning as a result of unbalanced load detection

1) Laundry may pile up on one side of the drum when you run your machinewith less laundry. There is the risk of damaging the washing machine when it is operated in higher speeds with unbalanced load. Therefore, when the unbalanced load in the machine is calculated more than the limit value, the machine does not spin for safety reasons.

2) Piling up of laundry at one point in the drum will be higher when the machine is operated with a single pullover, bathrobe or towel. Avoid washing such laundry as one piece as much as you can.
