Troubleshooting Tests 5 Test Check/Test Activity Steps Number Correction Test 1 1. Is the incoming water flow normal? Yes, go to step (4). No, go to step (2). 2. Are the incoming water faucets turned on? No, turn water faucets on. Yes, go to step (3). 3. Is the incoming water pressure above 20 psi? No, have customer correct pressure problem. Yes, check for kinked or blocked incoming water hoses, clean the incoming water screens. If problem still remains, replace the water inlet valve assembly. 4. Does the fill water continue to enter the washer? Yes - Go to step (5) No - Go to step (6) 5. Remove power from the washer. Did the water fill stop? Yes - Go to step (6) No - Replace the inlet valve assembly. If pressure switch checks good, go to step (7). If pressure switch checks bad, replace pressure switch. 6. Replace the pressure sensor. If this did not correct the problem, go to step 7. 7. Replace the main control board. Test 2 1. Is the washer leaking water? Yes, correct water leak. No, go to step (2). 2. Is there an air leak in the pressure sensor system? Yes, correct the air leak problem. No, go to step (3). 3. Replace the pressure sensor. If this did not correct the problem, go to step (4). 4. Replace the main control board. Test 3 1. Check the drain hose for restrictions. If there is a restriction, correct the problem. No restriction, go to step (2). 2. Start the washer and check for 120 VAC at the drain pump. If reading zero, check the wiring. If wiring good, replace the main control board. If reading 120 VAC, remove the pump and check for blockage. If blocked, remove the restriction, if not, replace the pump. Test 4 Inspect the wiring between the pressure sensor and the main control board. If wiring defective, correct wiring. If wiring OK, replace pressure sensor. If this does not correct the problem, replace the main control board. Test 5 1. Is the water level above 4.5 inches? Yes, go to step (2). No, go to step (4). 2. Does water enter the washer continuously? Yes, go to step (3). No, check air trap for clog, if not replace the main control board. 3. Remove power from washer. Does the water stop coming in? No, replace water valve assembly. Yes, check wiring to valve assembly for shorts. If wiring is good, replace the main control board. 4. Replace the pressure sensor switch. Did this correct the problem? Yes, problem solved. Test 6 1. Is the loading door closed? No, close the door. Yes, go the step (2). 2. Can you hear the lock attempt to close? Yes, check the door strike. If good, replace the door No, go the step (3) 3. Check wire connection between door lock and main control board. If good, replace the door lock. Then if problem is not fixed, replace the main control board. Test 7 Disconnect the plug from the drive motor and measure the resistance pins If the reading is between 105 to 130 Ohms, replace the motor control board. 4 & 5 in the motor. If the meter reads outside 105 to 130 Ohms, replace the motor. Test 8 1. Find out if the unit was overloaded. If not, remove the belt from the motor and spin the motor pulley. Does the motor spin free? No, replace the motor. Yes, go to step (2). 2. Spin the tub pulley. Does the tub spin free? No, check the tub bearings. Yes, go to step (3) 3. Disconnect the plug from the motor and measure the resistance of the If the readings are correct, check wiring from motor to motor control board, windings (pin 1 to pin 2, pin 1 to pin 3, pin 2 to pin 3). If good, replace the motor control board. If the readings are incorrect, replace All readings should be between 3 and 6 Ohms. the motor.
