Operation

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 water level at the end of the stop routine.

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.

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

A small indicator lamp on the side of the control module will light to indicate that a thermal overload switch in the motor has shut off the AC power to the computer board, thereby preventing damage to the motor caused by overheating and/or an overload condition. This feature protects and extends the life of the motor.

The thermal overload switch will automatically reset itself after the excessive heat condition has subsided.

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

●Machine not fully drained before spin

●Out-of-balance condition

●Low voltage

●Loss of one phase on a three-phase motor

●Bad bearings

●Air circulation blocked to motor

Contact a service technician to correct serious problems. Failure to take corrective action will ultimately result in damage to the motor.
