2 ~ ~ ~ * * Temperature Sensor Error When the UPM receives a signal from the
thermistor that is outside the range of the
UPM programming, the temperature sensor
error will actuate
. The UPM will signal an
error if it reads a resistance greater than
430 k and less than 15 k.
Check and replace
Thermistor as necessary.
3 ~ ~ ~ * * * Over Current Error If any of the high voltage components begin
drawing excessive current, the current
sensor will send a signal to the UPM to start
the Over Current Error and deactivate the
contactor which turns the power off to the
machine. Check and replace the
transformer, motor and/or heater as
necessary.
4 ~ ~ ~ * * * * Over Temperature Error If the fluid temperature in the wash tank
exceeds 135°F it will activate this error
message and stop the machine. This error
code cannot be reset until the fluid is
drained below the low level sensor in the
wash tank.
5 ~ ~ ~ * * * * * Current Sensor Error The UPM must receive a signal from the
current sensor to verify that it is connected
and working. If it does not receive the
signal, the UPM program will stop the
machine and give this error code.
6 ~ ~ ~ * * * * * * Membrane Error In the event that one of the control panel
buttons sends a constant signal to the UPM,
the program will recognize that the
membrane is defective and display this
error code (see Section 6.9 Push Button
Membrane).
