Troubleshooting Chart - GE GMAN1200 Manual

FOR SERVICE TECHNICIAN ONLY—DO NOT REMOVE OR DESTROY
Code(s) Description
22, 23 Fill problems • Ensure manual water valves are fully open.
• Check if water strainers on solenoid valve assembly are clogged.
• Check for obstructions inside inlet water hoses.
• Ensure solenoid valves do not leak when the valves are de-energized and the washer is powered down.
• Measure coil resistance for both valves; if outside range (1000–1250 ohms at room temp.), replace solenoid valve assembly.
IF ABOVE STEPS DO NOT CLEAR THE PROBLEM, OR FOR ERROR CODE 23:
• Replace solenoid valve assembly.
31 Drain • Ensure pump strainer is clean and free of debris.
problems • Check for obstruction inside the drain hose.
• Check pump impeller blades and bearing; if evidence of blade damage or seized bearings are present, replace the pump.
• Check electrical connections at the pump motor and harness.
• Measure pump motor resistance; if outside range (9–14 ohms at room temp.) replace the pump.
38, 39 Dispenser • Check for obstruction in dispenser mechanism and linkages.
problems • Check electrical connections at dispenser motor feedback switch and in the harness.
• Check electrical connections of water valves in the harness.
IF ABOVE STEPS DO NOT CLEAR THE PROBLEM:
• Replace dispenser motor assembly.
42, 44, 46 Motor Drive • Ensure all 4 shipping bolts have been properly removed.
47, 48, 49 operation • Remove all foreign objects that may be lodged between inner and outer basket.
above design • Look for signs of seized bearing(s) on basket and drum motor, replace components as necessary.
limits • Inspect condition and mounting of door gasket, replace and re-mount as necessary.
• Ensure inner basket (drum) can rotate freely.
IF ABOVE STEPS DO NOT CLEAR THE PROBLEM:
• Replace motor drive or drum motor.
43, 4A, Motor Drive • Measure AC outlet voltage, ensure correct range (102V to 132V AC).
4B, 4C, internal • Check electrical connections at the drum motor, motor drive.
50, 52, problems • Check harness integrity between main control and motor drive.
53, 54 • Unplug the unit, wait 30 seconds, restart the unit.
• If the fault persists and re-appears – replace the motor drive.
55, 56 Main Control • Replace the main control.

problems
57, 58, Main Control • Unplug the unit, wait 30 seconds, re-start the unit.
71 internal • If the fault persists and re-appears – replace the main control.
problems
60, 61 DOOR LOCK • Check integrity of wiring and connections between main control and DOOR LOCK mechanism.
63, 64, assembly • Investigate DOOR LOCK mechanism, check door microswitch operation, lock and unlock solenoid continuity, contact integrity;
problems
IF ABOVE STEPS DO NOT CLEAR THE PROBLEM:
• Replace the main control.
65, 80, Water Level • Check integrity of wiring and connections between main control and Water Level Sensor.
81, 82 Sensor • Check integrity of Water Level Sensor, replace if necessary.
problems
IF ABOVE STEPS DO NOT CLEAR THE PROBLEM:
• Replace the main control.
66, 67 Water • Check integrity of wiring and connections between main control and Thermistor Assembly.
Temperature • Using ohmmeter, measure Thermistor resistance; if outside expected range, replace Thermistor Assembly.
