Error Recovery Routine

When the computer detects an error, it will stop running the current step and display a message to indicate what type of error was found:

“FILL” indicates that the washer-extractor did not fill within the allotted time.

“EMTY” indicates that the washer-extractor did not drain in the allotted time.

“TEMP” indicates that the temperature sensor has recognized an over-temperature-limit condition.

“ME” indicates that the computer has detected a problem with the cycle information. The cycle must be edited.

“WATER” indicates that the WE-6 computer senses low, medium, or high water level at the end of the Stop routine.

NOTE: If low, medium or high water levels are sensed after a power failure, the computer will not energize the door unlock output but will permit the user to select and start a cycle to drain the machine.

All outputs remain off while the message displays, and the door cannot be unlocked.

NOTE: The WE-6 computer will not allow the door to be opened while there is water in the washer- extractor.

Each of these errors is considered to be recoverable. The operator has two minutes to respond to the error condition (except in the case of “WATER”). During this time, the computer will turn the signal (buzzer) relay on and off at the rate of one second on and one second off to alert the operator to the error condition. The washer-extractor may be restarted by pressing the Enter key. Pressing the Enter key will restart the cycle step for the originally programmed time period. The cycle may be aborted by pressing the Clear key. After aborting the cycle, the computer will go to the normal stop routine. If the operator does not respond to the error condition within the allocated two minutes, the computer will automatically abort the cycle.

NOTE: The “TEMP” alarm can be recovered only after the temperature falls below the alarm level.

Operation

Certain error conditions are considered to be non- recoverable:

If the door opens during a cycle, the computer will display “DOOR”. The operator must close the door.

Then, after the computer has detected that the door is closed, it will automatically abort the cycle and go to the normal Stop routine.

“OVERHT” will be displayed when the computer detects an open or shorted temperature input circuit or temperatures are outside of the washer- extractor’s allowable limits. Contact a service technician.

Motor Thermal Overload Indicator

NOTE: Does not apply to models made after December 1999.

To protect the motor from damage due to excessive temperature, a thermostat is embedded in the motor.

135-Pound Capacity Models

If the thermostat becomes too hot, a red indicator lamp inside the WE-6 control module will light; and power will be removed from the drive. The machine will resume normal operation only when the motor has cooled sufficiently.

250-Pound Capacity Models

If the thermostat becomes too hot, the inverter drive will shut down. When this occurs, the red Drive Fault indicator inside the WE-6 control module will illuminate. When the motor has cooled sufficiently, the washer-extractor can be reset by removing power for five minutes. (A service technician can positively identify the problem by looking for Auxiliary Fault “F02” in the drive’s fault memory.)

Before attempting to restart the washer-extractor,determine the reason for the overload. The following is a partial list of possible problems:

Bad motor bearings

Motor cooling fan blocked or not operating

Excessively dirty motor (lint build-up, for example)

Room temperature higher than 120°F (50°C)
