Test Procedure Measure resistance of terminals on each valve. Resistance across each valve ............. Do not disconnect the pressure hose from pressure switch to perform measurements. Measure resistance across the following terminals on the pressure switch: Terminal 1 to 2 ................................ Terminal 1 to 3 ................................

Drain pump
Approximately 1000 Ω ± 10% Refer to wiring diagram/schematic for correct contacts. Air pressure that actuates switch is determined by the water level of the tub. Continuity (no pressure) Continuity (pressure)
Disconnect wire terminals from switch. Test terminals with switch closed....... Test terminals with switch open .........

Results
Continuity Infinite
>1 Ω 1 MΩ
Replace all three brake pads. Apply a thin layer of silicone (26594P) on pads, see Service Bulletin “ASQ− 213− B”
Discharge Capacitors 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. Type of motor: Three speed
Terminal to Case: Infinite resistance
Verify drain pump is not clogged or damaged.
Remove clog and verify proper operation.
See following section “Internal Motor Diagram and Schematic” for correct wiring contacts.
Replace drain pump if damaged. 40032701
Transmission assembly
Type of transmission: 710 rpm
Externally identical, must be identified by part number. If transmission locks-up, replace.
40053601
Drive belt
Type of drive belt: 710 rpm
Refer to “Parts Manual”, to verify which drive belt and pulley size is required.
There are two different types of pulley sizes as well.

WARNING
To avoid risk of electrical shock, personal injury, or death, disconnect power to washer before servicing, unless testing requires it.
SELF-DIAGNOSTIC ROUTINE
TEMPERATURE REGULATING CIRCUITRY ROUTINE: THIS ROUTINE WILL ALLOW A CHECK OF THE TEMPERATURE REGULATING CIRCUITRY. ONCE THIS ROUTINE IS ENTERED, THE CONTROL WILL DISPLAY A CODE IN THE 2-DIGIT VFD DISPLAY INDICATING A TEMPERATURE OF THE WATER.
ENTRY: FOLLOW THE SEQUENCE GIVEN BELOW 1. MAKE SURE WASHER LID IS CLOSED. 2. START IN THE SLEEP MODE (DISPLAY COMPLETELY OFF).
SEQUENCE TO ENTER TEMPERATURE REGULATING CIRCUIT ROUTINE 1. START IN THE SLEEP MODE (DISPLAY COMPLETELY OFF) 2. PRESS DELAY START PAD AND HOLD. 3. NOW PRESS THE START PAD. 4. RELEASE BOTH PADS. 5. CONTROL NOW WILL DISPLAY THE AMBIENT TEMPERATURE OF THE THERMISTOR AS INDICATED IN THE TABLE BELOW. DISPLAY TEMP (±3°F) DISPLAY TEMP (±3°F)
3. PRESS THE SIGNAL VOLUME PAD AND HOLD. 4. NOW PRESS THE START PAD THEN RELEASE BOTH PADS WHEN SEQUENCE STARTS. 5. IF UNABLE TO START ROUTINE CHECK LID SWITCH.
