TESTING INDIVIDUAL
COMPONENTS
NOTE: The following troubleshooting procedures re-
quire the use of a volt/ohm meter. If you are not familiar
with using a volt/ohm meter do not attempt to perform
the following troubleshooting procedures. If you need
assistance please contact your distributor or call a
customer service representative.
Wash Cycle, Heater, and
Oil Skimmer Timers
Step 1:
Disconnect power to the machine.
Step 2:
Remove the timer from the control panel
and disconnect all wires (See Timers and Switches
on the Control Panel).
Step 3:
With the timer in the OFF position, test for continuity
using an ohm meter.
If there is continuity the timer is no longer functional;
replace the timer.
Step 4:
With the timer in the ON position, test for continuity
using an ohm meter.
If there is not continuity the timer is no longer functional;
replace the timer.
Door Safety Switch
Step 1:
Disconnect power to the machine.
Step 2:
Remove the switch from the rear of the machine and
disconnect all wires (See Door Safety Switch).
Step 3:
With the switch fully open (not depressed), test for
continuity.
If there is continuity the switch is no longer functional;
replace the switch.
Step 4:
With the switch fully closed (depressed), test for
continuity.
If there is not continuity the switch is no longer
functional; replace the switch.
Single Phase Heating Element
Step 1:
Disconnect power to the machine.
Step 2:
Remove the cover from the heating element and
thermostat enclosure (four screws; use a 5/16” wrench
or socket).
Step 3:
Detach the power leads from the heating element
(See Figure Below).
Step 4:
Use an ohm meter to measure the resistance of
the heating element. The resistance should be
approximately 10 Ohms; if not, replace the heating
element (See Heating Element).
Three Phase Heating Element
A three phase heating element is a complex component.
Please contact your customer service representative
for testing instructions.
Single Phase Thermostat
Step 1:
Disconnect power to the machine.
Step 2:
Remove the cover from the heating element and
thermostat enclosure (four screws; use a 5/16" wrench
or socket).
