Regulating
temperature
The unit is attempting to regulate the fluid
temperature as it has reached the preset limit. The
power is reduced to control this. (see page 16)
Tank overheated
The unit was unable to control the fluid temperature
and it has risen above the preset limit. Allow the
cleaning fluid to cool.
MOSFET
overheat
The internal electronics have overheated. This could
be due to extended periods of use or environmental
conditions. Allow the unit to cool for 30 minutes
before trying the cycle again. If this message
regularly appears the unit should be taken out of
service and contact Walker Electronics Ltd.
Check fluid
A problem with the cleaning fluid was detected. This
would normally be an issue with the fluid level or
excessive fluid contamination. Fill the tank to the
correct level with fresh fluid.
Lid is open
The lid is not in place or incorrectly seated or there is
a problem with the sensor. Remove and replace the
lid. If the problem persists remove the unit from
service and return for repair.
Lid is closed
The lid is correctly positioned and a
cycle can be started.
Cycle passed
or Cycle failed
Either the unit operated correctly and the cycle
passed all parameters or the cycle failed and should
be re-initiated. A list of reasons for failure is printed
on page 24 of this operator’s handbook.
Extended
The expected number of joules (watt.second) fell
below that expected and the time has been
increased by the machine accordingly to ensure
correct cleaning of the load.
Error xxx
The unit has may have a fault. IMMEDIATELY contact
Walker Electronics for further advice.
