Abnormal Conditions

Door Open During Operation

If the control senses either a momentary or sustained open door while the machine is operating in a wash cycle, the control immediately attempts to halt rotation of the cylinder, and all outputs not required to effect rapid halting of the cylinder rotation de-energize immediately. The message “dOOr” then displays as long as the condition persists. Regardless of the duration of the open door condition, once it is recognized by the control, the control aborts the cycle and goes to the stop routine if the door is closed (otherwise all outputs turn off and display shows “dOOr”).

Excessive Fill Time

As indicated elsewhere in this definition, fill times exceeding 10 minutes cause the cycle to abort and the display flashes “StOP”/“FILL” or “ErFL” and sounds the buzzer for ten seconds prior to entering the stop routine (display shows “01” minutes remaining while in the stop routine).

Out of Balance

If the wash load becomes out of balance, the machine will attempt to balance the load. After three failed attempts, the display will light the leftmost digit and a lower spin will be used to complete the cycle.

WARNING

Operating the machine with severe out-of- balance loads could result in personal injury and serious equipment damage.

W728

Door Will Not Open

At the end of a cycle or at power up, before the control will allow the door to unlock, control checks for low, medium or high water level. Control allows the door to unlock only when machine is empty. If any water level is indicated, display shows “FULL” while keeping all outputs off. This condition could indicate a slow drain system or a mechanical blockage of the drain. Contact a qualified service technician about display on control.

Excessive Drain Time

If cycle aborts, with display flashing “Erdn” with buzzer sounding, the machine did not empty after 4 minutes 15 seconds in a drain step.

Temperature Probe Sensor Problem

If display shows “tSFL”, the machine has a temperature sensor failure. This could mean the sensor is not connected or the sensor has failed.

Clean Filter LED On

Variable-Speed Models Only

If the bottom indicator LED on front panel decal lights, the temperature sensor in the inverter drive compartment is indicating the temperature is undesirably high. Check and clean the drive compartment filter if necessary. Once corrected, the light turns off AFTER one cycle runs at a normal temperature.

WARNING

To reduce risk of electric shock, severe injury or death, allow machine power to remain off for three minutes minimum prior to working in and around AC drive. Proceed with caution.

Test Cycle

The test cycle provides a convenient means of troubleshooting and testing all machine functions quickly.

1.Enter PROGRAM Mode.

2.Press the ∨ keypad. Display shows “tESt”.

3.Return the Program/Run switch to the right.

4.Press START keypad. The door locks and the TEST Mode starts.

5.Display shows “SPC?”. This is a factory test procedure. Ignore it and the machine will advance into the test cycle after about

five seconds or go to “bAl?” if variable-speed.

NOTE: For variable-speed models ONLY, display shows “bAl?”. This is also a special factory test procedure. Ignore it and the machine will begin the test cycle after a few seconds.
