Section 5 Service Procedures
To reduce the risk of electrical shock, fire, explosion, serious injury or death:
• Disconnect electrical power to the washer-extractor before servicing it.
• Close the gas shut-off valve to the washer-extractor (when applicable) before servicing it.
• Never start the washer-extractor with any guards/panels removed.
• Whenever ground wires are removed during servicing, these ground wires must be
reconnected to ensure that the washer-extractor is properly grounded.

36. DRAIN VALVE
If the washer-extractor doesn’t drain within 30
seconds, perform the following check. Refer to
Figure 23.
a. Turn off power to the machine.
b. Remove any panels necessary to access the
drain valve and drain plumbing.
c. Check for a clog in the drain line.
d. Verify that the drain valve is opening.
(1) The drain valve is normally open (i.e., it
requires voltage to close).
(2) When power is removed from the machine,
the drain valve should open.
e. If the drain is not opening, check for the
following:
(1) Check the motor winding for continuity, a
short circuit or an abnormal drop in voltage.
Replace the drain valve motor as needed
(consult the machine’s parts manual for
drain valve motor part numbers).
(2) Check that the shaft and rotor of the drain
motor turns freely.
(3) Check that the internal drain valve is
closing and does not bind. A clog within the
drain valve may be preventing the drain
valve from closing. Replace the drain valve
as needed (consult the machine’s parts
manual for drain valve part numbers).
f. Re-install any panels removed in Step 2.
37. FLANGE RELAY REMOVAL AND
INSTALLATION
a. Turn off power to the machine.
b. Remove the two screws at the top rear edge of
the module top cover and slide the cover back
slightly until it can be removed. Remove the
module top cover.
c. Remove the quick disconnect from the top of
the flange relay. Refer to Figure 24. All wires
remain in the same spot.
d. Remove one of the screws that attaches the
flange relay to the control module. Refer to
Figure 24.
e. Loosen the other screw that attaches the flange
relay to the control module.
f. Remove the flange relay. Refer to Figure 24.
g. Installation is the reverse of removal.
