No Power
Look for Correction
1 Incoming voltage between L1 and L2 (L1-
L2)
(Also L1-L3, L2-L3 if 3 phase) Check Heater and replace as necessary.
2 Less than 10 volts to UPM
(leave UPM plugged in during check) Water too hot, above 135°F – empty sink
and refill with 115°F water.
Tighten the External Wiring Harness on
back of Control Panel.
Check transformer and replace as necessary.
Check thermal cutoff for heater and replace
as necessary.
Check thermal cutoff for motor and replace
as necessary.
Error Codes
~ Represents a “long” flash
* Represents a “short” flash
Look for Correction
1 ~ ~ ~ * Liquid Level Error This error appears when the upper liquid
level sensor sends a signal to the UPM (W-H
light is illuminated) and the low liquid level
sensor is not sending a signal to the UPM
(W-L is not illuminated). The low level
sensor may not be functioning due to a
coating of debris or a broken/disconnected
wire that is preventing the signal to the
UPM. A continuous signal from the upper
level sensor can be caused by debris coating
the face of the sensor or faulty wiring that
has the sensor connection grounded to the
wash tank when there is no fluid in the tank.
The liquid level lights on the UPM can be
used to help determine the problem.
