Problem Possible Cause Checks & Tests
Incorrect Water
Temperature
Water hose installation. Make sure inlet hoses are connected properly.
Temperature thermistor. See TEST #5: Temperature Thermistor.
Valve problem. See TEST #2: Valves.
Main Control problem. See TEST #1: Main Control (ACU).
Won’t Agitate
Water covering the impeller? See TEST #6: Water Level.
Is lid lock showing open during the cycle? See TEST #8: Lid Lock.
Harness connections. Check harness connections between main control and drive system.
Shifter problem. See TEST #3a: Drive System – Shifter.
Motor problem. See TEST #3b: Drive System – Motor.
Main Control problem. See TEST #1: Main Control (ACU).
Won’t Spin
Is lid lock showing open during the cycle? See TEST #8: Lid Lock.
Harness connections. Check harness connections between main control and drive system.
Shifter problem. See TEST #3a: Drive System – Shifter.
Motor problem. See TEST #3b: Drive System – Motor.
Main Control problem. See TEST #1: Main Control (ACU).
Won’t Drain`
Drain hose installation. Check for proper drain hose installation. Make sure it is not inserted
more than 4.5" (114 mm). Make sure drain hose is not sealed into
drain pipe, and that there is an air gap for ventilation.
Standpipe position. Ensure drain height is between 39" (991 mm) and 8" (2.4 m) above
the floor.
Plugged drain hose. Check drain hose for obstructions.
Obstructions to drain pump. Check tub sump under impeller plate & basket for obstructions.
Harness connections. Check harness connections between main control and drain pump.
Drain pump. See TEST #7: Drain Pump.
Main Control problem. See TEST #1: Main Control (ACU).
Cycle Time Longer Than
Expected
Oversuds. 1. Verify use of HE detergent.
2. Excessive detergent usage.
Off balance. 1. Load is off balance.
2. Balance ring water leak.
Drain hose installation. Check for proper drain hose installation. Make sure it is not inserted
more than 4.5" (114 mm). Make sure drain hose is not sealed into
drain pipe, and that there is an air gap for ventilation.
Standpipe position. Ensure drain height is between 39" (991 mm) and 8' (2.4 m) above
the floor.
Draining slowly. Check for pump or drain hose obstructions.
Water pressure drop. Results in longer fill time.
Friction or drag on drive. Check motor and bearings; check for items between tub and basket.
Weak suspension. Basket should not bounce up and down more than once when
pushed.
