Introduction

Theory of Operation

General (Dryer)

The dryer uses heated air to dry loads of laundry. When the motor is started, the exhaust fan pulls fresh air in through louvers at the rear of the dryer and over the heat source (burner flame for gas and heating element for electric). The heated air moves through the heater duct and into the cylinder, where it circulates through the wet load. The air then passes through the lint filter, air duct and exhaust fan, where it is vented to the outdoors.

General (Washer)

This frontload washer provides some of the same principles of operation as the typical topload washers. It senses water level, it dispenses the desired laundry detergent, agitates the clothes for good cleaning action, removes the water out of the washer and spins the clothing in preparation for the dryer.

The difference in operation is primarily the rotational washing agitation created for the horizontal basket and drum. This agitation tumbles the clothes in a clockwise, pause, and counter-clockwise direction. This reversing tumbling action provides an efficient washing process and requires less laundry detergent and less water.

The cycle begins by locking the loading door after the vend is satisfied. The type of cycle and water temperature are determined by the appropriate pads on the electronic control.

The inner basket starts agitating during the wash water fill. A column of air is trapped in a pressure bulb and hose. The air pressure continues to increase as the inner basket fills with water with the pressure sensor monitoring the water level.

The agitate step tumbles the clothing in a clockwise direction for a period of time, pauses for a period of time and then tumbles the clothing in a counterclockwise direction for a period of time. This agitation continues until the end of the wash cycle. The machine then stops agitating and turns on the pump or drain valve which removes the wash water.

After all the rinse cycles have been completed, the washer goes into a final spin cycle to extract as much water as possible from the clothing to prepare them for the dryer. The spin speeds and duration of this final spin cycle are determined by the type of wash cycle selected.

NOTE: Washer may not reach 1200 RPM because of an out-of-balance condition. Control may limit speed to 1000, 800, 650 or 500 RPM depending on severity of out-of-balance condition.

Technical (Washer)

The basic operational system of this washer consists of the electronic control, the inverter control, pressure sensor, water valves, electric pump (or drain valve) and A.C. motor.

The electronic control performs all control and timing functions. The electronic control sends simple speed and output commands to the inverter control via serial communication. The drive control powers the door lock, pump (or drain valve), motor, water valves and heater (if equipped).

The drive control powers the A.C. motor and performs all motor control functions. The drive control also powers the water valves, dispenser valves and door lock. The drive control is powered through the door switch and electronic control. The drive control also alerts the electronic control to any errors in the motor.

Before entering any spin step the drive control measures out-of-balance. The drive control will try to redistribute the clothes if an out-of-balance condition exists by limiting the spin speed to several speeds depending on the severity of the out-of-balance condition. If the out-of-balance condition is severe enough the drive control will limit speed to 90 RPM and will not spin.

NOTE: An additional out-of-balance switch is used to detect any out-of-balance condition during spins. If this switch opens during a spin step, the drive control immediately stops and then restarts the spin.

Upon completion of the wash cycle, the machine goes into a rinse cycle. Fresh cold water is brought into the inner basket via the mixing valve until the fill level is satisfied. The rinse cycle consists of agitation for a predetermined amount of time then a spin mode with the pump running where the machine goes into a series of spins.

This step checks the heater operation. The display shows “xx”, where xx is the temperature in degrees Celcius. The control will heat the water to 40 degrees Celcius while displaying the temperature as it rises at a rate of 1 degree. If the temperature sensor is open or shorted, the display will show “Er” and “OP” or “SH”.

Overflow Test

This test checks the overflow setting for the water level sensor. When the overflow level is reached, the water valves, all External Supply Valves and the Cycle Run Output will automatically turn off. The control will not advance to the next step until the overflow level is satisfied.

Low Agitate

This step checks the Low Agitate speed. The display shows “LA”, the Rinse LED is on, the Auxiliary Output 3 is on, Cycle Run Output is on, and the machine enters a low agitate. The control will remain in this mode until the Start/Pause keypad is pressed.

Regular Agitate

This step checks the Regular Agitate speed. The display shows “rA”, the Rinse LED is on, the Auxiliary Output 4 is on, and the machine enters a regular agitate. The control will remain in this mode until the Start/ Pause keypad is pressed.

Pump/Gravity Drain Test

This step checks the Pump output. The display shows “Pu” for an electric pump or “dr” for a gravity drain, the Rinse LED is on, and the Pump is turned on or the Gravity Drain is opened. The control will only advance to the next test step after the Water Level Sensor indicates that the drum is empty.

Factory Spin

This step checks the spin speeds. The display shows the most significant two digits of the actual RPM.

806221 15

The machine steps through spin speeds and maintains each speed for a few seconds. After 1200 RPMs, the motor will stop.This step lasts 4 minutes. All Out of Balance checking is done and if either the out of balance switch is hit or the OBL check fails and needs to re-spin, the time will be reset indefinitely to allow the load to be rebalanced so that it can spin up and reach full speed. The control will advance to the next step if the Start/Pause keypad is pressed at any time during this step.

During this step if 800 RPMs is reached, LED number 26 will be lit. If 1000 RPMs is reached, the LED number 25 will be lit. If 1200 RPMs is reached, the LED number 24 will be lit, and if 1100 RPMs is reached, the LED number 27 will be lit to indicate that a passing speed has been reached. Refer to Figure 1 for LED number definition.

Breakaway

This step checks the breakaway speed and the door unlock function. All valves will be open at the beginning of this step to allow the blowing out of the valves by the factory. The Start/Pause keypad must be pressed to start exiting the test. The first Start/Pause keypress will turn off the water valves, the second Start/Pause keypress will stop the motor and start the unlock process. The third Start/Pause keypress will start the unlock process. Once the door unlocks, it needs to be opened to finally exit the test. The water level sensor will be trimmed in this step after a 20 second delay and once the Start/Pause key is pressed the first time.

During this step the LEDs for indicating speeds reached from the Factory Spin step will remain lit in this step.

Power Down

This is the final step of factory test procedure. The control will display “Pd” to signify that the procedure has been completed and that the user can safely unplug the machine. Cycling power to the machine is the only way to resume normal operation.

Control is in Bootloader Mode. Control is waiting for firmware update. (Firmware

updates only done by Alliance Laundry Systems Service Technicians.) If firmware is not being updated, cycle power to machine. If error still occurs, replace control.

Control is in Low Power/Idle Mode. While control is in Low Power/Idle Mode, right most

decimal on display will blink once per minute. This is normal. Press the Power/Cancel keypad to turn control back on.

Fill Error Fill level is not reached within 30 minutes in any fill

step. Check for water pressure at inlets, water valves for operation, clog in water line, plugged filter screen on water hose, and the pressure sensor hose for air leak to determine cause of error. Power down to clear error.

Door Lock Fatal Error Door is unlocked during a running cycle. To clear this

error, cycle power to the machine. Check door lock and door latch for damage and replace if error continues. Also check door lock wire harness for damage or for disconnection.

Door Lock Non-Fatal Error If the door fails to lock in 20 seconds in Door Locking

Mode after the drive has been enabled, the control will turn off all outputs and display error code. To clear this error the door must either open or lock. Overloading the machine or broken shocks may keep door from properly closing. First check that door is fully closed. If door still

Door Unlock Non-Fatal Error If the door fails to unlock 20 seconds after the drum has

stopped spinning with a solenoid type door lock and all other outputs have been turned off, the control will display error code. To clear this error the door must unlock or open. Removing power for 3 minutes will automatically allow door lock to unlock. Make sure to press on door and then pull to unlock the door as pressure on door lock/latch will prevent door from unlocking. Possible causes of this issue are broken shocks or clothes load causing pressure on door and door latch/ lock preventing it from unlocking. If it still fails to unlock, check door lock and latch for damage. Also check door lock wire harness for damage or disconnection.

Door Opened Error Control detects door open during a cycle. This can be

caused by pulling on door while locked or about to lock. Correct inoperative door locking system. Check door switch and harness for damage or disconnection. Unpower machine to clear error.

Non-Fatal Unbalance Error Washer is unable to balance load. Redistribute load and

run cycle. If running a small load or one large item, add more items to help machine balance the load better. If items are rubber or other water resistant type material, load may never reach full spin speed. Ensure machine is properly leveled and check for broken shocks. Open door or press Power/Cancel keypad to clear error.

Fatal Unbalance Error Wires to unbalance switch are broken or not connected,

unbalance switch may be stuck closed or a shock may be broken. Unpower to clear error.

Door Open Indicator Door needs to be closed to start cycle. If door is closed,

check for improper wiring or faulty door switch.

Brownout/Voltage Configuration Unexpected supply voltage. Check the harness

connections between the front end control and the drive board. If the front end control was replaced, set dip switch #1 to the same setting as the previous control. If reworking the machine to use a different voltage supply, the dip switch #1 setting may need to be changed. If the dip switch #1 setting is changed, power down, power up and try again. Also check Pin H2-7 on the front end control to ensure good connection between front end control and drive board.

Drive Board Not Ready Hardware failure. Try cycling power to machine before

replacing drive board.

Drive Board Shorted Hardware failure. Try cycling power to machine before

replacing drive board.

Drive Board Communication Error Communication failure. Power down, power up and try

again. If error persists, check connection between front end control and drive board, or try replacing the front end control or the drive board. Many times a loose pin or wire is at fault for this error.

Drain Error The control will enter Machine Error Mode when the

water height is not below the empty level, after attempting to drain for 2 minutes. In the event of a drain error, the control will turn off all outputs and turn on the Machine Error Tone for 15 seconds. Check wiring to drain and that power is present at drain. Check for objects stuck in drain hose or in pump on electric pump units. Ensure that drain hose meets drain height restrictions. Unpower to clear error.

Slow Drain Error This error occurs only if enabled by setting dip switch

#4 to ON. Water is not draining as quickly as expected in any cycle step that drains water during the cycle. Clear this error by pressing the Power/Cancel keypad.

Heater Error (machines equipped with heater)

If the heater is enabled and the water temperature has not reached the desired temperature selection within 2 hours, the control will indicate a heater error. If this error occurs, the heater output will be turned off and the cycle will continue. This error will be cleared when the door is opened or the Power/Cancel keypad is pressed. Possible causes include wire harness to heater elements are damaged, heater elements are damaged, corrosion of wires/connectors.

Max Temperature Exceeded Error (machines equipped with heater)

Open Temperature/Thermistor Sensor Error (machines equipped with heater)

Table 8 (continued)

The control will continuously monitor the Machine Status for an indication that the maximum water temperature is exceeded. When the cycle has been completed and if the control has saved a Max Temperature Exceeded Error, the control shows the error for one minute after the door is opened or the Power/Cancel keypad is pressed. Check for stuck heater relay/contactor.

The drive board will flag an Open Thermistor Error any time it senses a temperature less than 0°C (32°F). The heater output is turned off for the remainder of the cycle. At the end of the cycle, error code will be shown. It clears after one minute or with the Power/Cancel keypad press. Check wiring to heater elements and thermistor for damage.

Shorted Temperature/Thermistor Sensor Error (machines equipped with heater)

The drive board will flag a Shorted Thermistor any time it senses a temperature greater than 100°C (212°F). The heater output is turned off for the remainder of the cycle. At the end of the cycle, error code will be shown. It clears after one minute or with the Power/Cancel keypad press. Check wiring to heat elements and thermistor for damage.

Suds Lock Error In the spin steps, if the control determines that there are

suds in the machine after running all Suds Removal Routines programmed to run, it will display a Suds Lock Error at the end of the cycle after the door is opened. The control will continue showing the error for one minute or until the Power/Cancel keypad has been pressed. To prevent error, reduce detergent used. Check for draining issues, check that drum spins freely, and make sure no small items are lodged between drum and outer tub.

Too Hot To Drain Error If water is detected to be too hot to drain safely, this

error will occur. It is advised to add the Cool Down feature by setting #6 dip switch to ON to avoid this error. Another possible cause of this error is that the heater contactor/relay is stuck on. Error will display after door is opened in End of Cycle Mode. It will clear after 1 minute or the Power/Cancel keypad is pressed.

, 

Water Leak Drain Error This error occurs only if enabled by setting dip switch

#4 to ON. If there is a leak during the water leak detection of the cycle an error will display after the door is opened at the end of cycle for 1 minute. It will clear after 1 minute or until the Power/Cancel keypad is pressed. If the water level has dropped more than an acceptable amount during a water leak drain check, the control will save a water leak drain error status and will continue the machine cycle. The cause of this error may be the drain hose, pump, or fill valve leaking or a stuck gravity drain valve on gravity drain machines.

No Water Flow Error If the control does not reach a water level of 4 inches

within the first 5 miutes of starting the fill it may mean the hose to the pressure sensor has a leak, is disconnected or clogged, the water inlet hose is clogged, the water inlet screens are clogged, or no water is flowing into the machine. The control will enter Machine Error mode when the error is set. The control will first drain for 90 seconds and then turn off all outputs and turn on the Machine Error Tone for 15 seconds. Unpower to clear error.

Overflow Error This error is triggered when an unsafe high water level

is detected in the machine and water is unable to drain. The water valve may be stuck open, pump may be stuck, or the drain may be clogged. Typically a small item is lodged in the propeller of the pump on pump machines. The door may be open/unlocked with water sitting in the machine to cause this error. Unpower to clear error.

Pressure Sensor Error If the control does not detect a valid water level sensor

input for 30 seconds, or if the Max (Overflow) Fill Level in the control is set to 0 while in Run Mode, Factory Test Mode, or Overflow Mode, the control will enter Machine Error Mode. Check harness from user control to pressure sensor for damage and replace if necessary. Replace pressure sensor or user control if error persists. The control will first drain for 30 seconds to get out any water and then unlock the door. Unpower to clear error.

Broken Belt Error If a broken belt is detected by the control, the control

will display this error. Unpower the machine and check the belt and pulleys for issues.

Water Leak Fill Error If there is a leak during the water leak detection of the

cycle when programmed on, an error will display after the door is opened at the end of cycle for 1 minute. It will clear after 1 minute or when a keypad is pressed. If the water level has increased more than an acceptable amount during a water leak drain check, the control will save a water leak drain error status and will continue the machine cycle. Immediately upon detecting the error the rightmost decimal point will be lit. This lit decimal point can be cleared by pressing the START keypad 3 times in a period of 5 seconds or by cycling the power to the machine. There may be a water valve stuck open due to debris or a failed water valve.

d. Momentary Power Interruption

Upon resumption of power, sensor contacts will still be open, permitting secondary valve to open. However, with the secondary coil in the circuit, the booster coil cannot draw enough current to open the split-coil valve. When sensor contacts do reclose, the secondary valve will close, and the burner system will be in the normal pre-ignition circuit.

Flame Failure

In case of flame failure, the sensor contacts will re-c

lose in about 45 seconds. This will close the secondary valve and the burner system will be in the normal pre-ignition circuit.

f. Ignition Failure

If flame is not established as sensor contacts open, secondary valve will remain open until sensor contacts re-close. Sensor will continue to recycle the igniter and secondary valve (about once per minute) until ignition is made or dryer is turned off.
