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.

If there is no spin, but the rest of the program
is OK:
a. When a medium or high-speed spin is
programmed, the computer looks for an out-of-
balance condition and an empty condition.
b. Check the input plug (J-2) on computer board.
Refer to Figure 5.
c. Check the balance switch that is located inside
of the frame.
d. Check the water pressure switch and the drain
line. Refer to Figure 1.
NOTE: When an “OUT-OF-BALANCE” condition
is detected, the computer will automatically reduce
the cylinder speed to the “WASH” forward speed to
allow the load to redistribute. The computer will
look for and attempt to correct the “OUT-OF-
BALANCE” three times in each spin step. If the
balance condition is still not corrected, the
computer will end the cycle.
If the basket goes into spin with water left in
the basket:
a. Check for leaks between the pressure system
and the water level switch.
If the display indicates “OVERHT”:
a. The temperature probe is short-circuited or has
an open circuit.
b. The machine will not perform a heat step until
this problem is resolved.
c. Replace the temperature probe in the sump and
recalibrate the temperature circuit. Refer to
Paragraph 30.
If the display indicates a “TEMP” alarm:
a. If this alarm is displayed, the temperature
sensor has recognized an over temperature limit
condition.
b. Adjust the water temperature as needed.
If the display indicates a “MEMR” alarm:
a. If this alarm is displayed, the computer has
detected a problem with the cycle information.
b. Review the cycle information and change it as
needed.
25. KEYPAD REMOVAL AND INSTALLATION
Removal
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 nut that attaches the metal
computer board cover and remove the cover.
d. Follow the keypad ribbon cable from the
keypad to the computer board that is inside of
the control module.
e. Unplug the connector at J-3 (located on the
bottom center of the computer board). Refer to
Figure 4.
f. Remove the four nuts at the corners of the
computer board. Carefully move the computer
board away from the front while sliding the
keypad ribbon through the slot in the module
front.
g. Carefully remove the old keypad from the
control module front. The keypad is self-
adhesive and separate from the control module
decal.
h. Remove any residual adhesive from the module
front.
NOTE: The module front surface must be clean and
smooth before a new keypad is applied. An uneven
surface will cause keypad malfunctions.
Installation
a. Insert the keypad’s plug and ribbon cable
through the slot in the module front.
b. Remove the backing paper from the new
keypad.
c. Align the keypad so that the cable is centered in
the slot. Press the keypad into place.
d. Carefully connect the ribbon cable plug to J-3 at
the bottom center of the computer board. Refer
to Figure 4. The cable must not be twisted and
the plug must be centered in the receptacle.
e. Reinstall the computer board and carefully
tighten the four nuts.
