Verify that the POWER light on the control panel and the LED #1 (Power
On) is illuminated on the UPM. If LED #1 is not illuminated, check:
• Main power supply circuit breaker.
• Fuse inside the control enclosure.
• Bi-metallic disc switch for water temperature (switch must be closed
if water temperature is below 120°F)
• Bi-metallic disc switch for motor temperature (switch must be
closed if motor temperature is below 150°F)
Check to see that the Liquid Level LEDs #3 and #4 are illuminated when
the wash tank is filled to the waterline.
Check to see that the Liquid Level LEDs #5 and #6 are illuminated when
the sanitize tank is filled to the waterline.
If any of the LED’s (3 thru 6) are not illuminated when the tanks are filled:
• Clean the liquid level sensors as described in the “Preventive
Maintenance” section of this manual.
• Be sure that all connections to and from the Liquid Level sensors
are secure and that there is no physical damage to the wiring.
• If damage to connectors and/or wiring is found, contact Power Soak
Systems, Inc. at 800-444-9624.
If the troubleshooting guidelines shown above do not correct the problem, it
will be necessary to contact Power Soak Systems, Inc. at 800-444-9624.

by observing LED #2 on the UPM and the “ERROR” green LED on the
front of the control panel. If there is a control logic error, the ERROR light
and LED #2 will flash with a “blinking” pattern. The definitions for the
patterns are as follows:
A “
