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
microcomputer senses low, medium, or high
water level at the end of the Stop routine.

“DRTEMP” indicates that the WE-6 has detected
water temperature over 160°F (71°C) in a “drain
to reuse” step. Instead of draining to a tank, the
computer gives this error message. The cycle
must be edited so the temperature is below 160° F
(71°C) upon entering a reuse drain step (“Da” or
“Db”).

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

NOTE: The WE-6 microcomputer 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.
