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

Fill times exceeding 10 minutes cause the cycle to abort. 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). The Fill Error Count will increase by one. Refer to Cycle and Error Count section.

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.

Drain Error (For Models With Firmware ID Code “o2HC”, “o2UC”, “ouHC” and “ouUC”)

If machine has not drained within 4 minutes 15 seconds, display flashes “Erdn”, time remaining, and beeper beeps. The beeper stops beeping after 30 seconds while display flashes “Erdn”until machine empties. If machine empties, ending Drain Error condition, display stops flashing, beeper turns off, and remaining cycle time displays as the cycle resumes.

If machine does not empty, display continues flashing “Erdn”. The drain error counter increases by one. Refer to Cycle and Error Count.

Temperature Probe Sensor Problem

If display shows “tSFL”, “-19c”, or “00F”, the machine has a temperature sensor failure. This could mean the sensor is not connected or the sensor has failed. If replacing the probe does not correct this, consult an authorized service person.

Frame Limit Switch Trip

If the display is flashing “baL/door”, the frame limit switch may have tripped during a high speed spin. This may be due to the door momentarily opening during the high speed spin. Contact a qualified service technician if this occurs.
