Drain pump
Results
See following section “Internal Motor
Diagram and Schematic” for correct
wiring contacts.
Remove wires from capacitor
terminals and connect ohmmeter,
set on highest resistance scale to
terminals.
Between Terminals: Meter should
momentarily deflect towards zero then
return to over 5 MΩ. If no deflection
occurs, or if continuous deflection occurs,
replace capacitor.
Also check between each terminal
and capacitor case.
Verify drain pump is not clogged or
damaged.
Terminal to Case: Infinite resistance
Remove clog and verify proper operation.
Replace drain pump if damaged.
