2. The following check should be made to determine if the drain
microswitch is defective.
a. Remove the two screws securing the microswitch to the
drain rod valve bracket.
b. Remove wires from the switch.
c. Check for continuity across the two outside terminals of the
drain switch. If the circuit is open, the drain switch is
defective. The circuit should only be opened by pressing on
the actuator of the drain switch.
3. Replace switch in reverse order.
1. Remove electrical power supplied to the unit.
To avoid electrical shock or property damage, move the
POWER switch to OFF and disconnect main circuit
breaker, or unplug cord at wall receptacle.
2. Remove the control panel above the switch.
3. Label and remove the wires from the switch. With test
instrument, check across the terminals of the switch with the
switch in the ON position, and then in the OFF position. With
the switch in the ON position, the circuit should be closed.
With the switch in the OFF position, the circuit should be open.
If the switch checks defective, replace it by continuing with
this procedure.
4. With wires removed from the switch, push in on tabs on the
switch and remove switch from the panel.
