Troubleshooting and error codes

Fault Code	Description	Trigger Condition	Action
0	No Faults	Displayed in Service Mode only when there are no faults to display.	• Displayed when no faults are found.
1	Lock Monitor	This fault is set if the motor shaft speed exceeds 45 RPM for 5 seconds while in spin mode and unlocked. This fault can also occur if the basket is manually spun by hand.	• Check the door lock using Service Mode spin test 14. • Check door lock harness connectors both at the main board and at the door lock assembly. • Replace door lock if this happens frequently.
2	Door Monitor	Control did not get Door closed signal from switch while motor was moving. Could mean the switch didn't close or control didn't get the signal because of lack of connection.	• Check the door lock using Service Mode spin test 14. • Check door lock harness connectors both at the main board and at the door lock assembly. • Replace door lock if this happens frequently.
3	Locked Rotor Monitor	For 5 straight seconds control not seeing signal changes indicating the motor is turning while trying to spin. Could mean the motor isn't rotating or control didn't get the signal because of lack of connection.	• Physically check the washer for anything preventing motor movement. • Verify hall sensor is connected to the main harness. Put washer in Service Mode and run test 14 (Spin). If hall sensor is bad or disconnected, the basket will start to spin normally and then stop spinning after approximately 5 seconds. Ensure hall sensor is properly connected and positioned on the motor. If basket spins for approximately 15 seconds, the hall sensor is most likely NOT the cause. • Measure the resistance of each motor phase winding, If TCO is tripped, wait approximately 45 minutes for TCO to reset and make sure motor moves freely and that nothing is jamming it, replace motor if it does not. • Check the door lock using service mode spin test 14. • If unit doesn't spin, replace inverter board or the main board.
6	Critical Flood Level by Pressure	Control received an extended period of pressure readings that is nearing over-flow levels. Voltage Output must be present. Could mean water did get that high due to briefly stuck water valve. Voltage output of sensor too high for actual water level because of sensor or water in pressure tube increasing pressure.	• Check pressure tube for pinches where it goes through main board. • Check pressure tube for trapped water. • Check water valve operation and for any leaking water valves. • Use pressure sensor test 10 to ensure correct pressure sensor operation. • Ensure pressure chamber port is free from obstruction using drill bit size 1/16-in. by hand so as not to drill through the inner wall.
8	Pressure Sensor Loss	Determines if appropriate pressure changes are seen during fill. It assumes there is a pressure leak, a clog in the pressure hose/system delaying the increase in pressure, or a significant amount water leaking out.	• Check to make sure house water supply valves are turned on. • Check water valve operation. • Check pressure tube for pinches where it goes through top cover grommet. • Use pressure sensor test 10 to ensure correct pressure sensor operation. • Check pressure tube for trapped water. • Ensure pressure chamber port is free from obstruction using drill bit size 1/16-in. by hand so as not to drill through the inner wall.
9	Door Switch Redundancy	Three cycles have been completed without any door opening.	• Open and close the door to clear the fault. • Check harness and connectors that go to the door switch. • Use test 13 to ensure system can detect the correct door state with the Spin and Rinse LED's. • Consumer education that four cycles cannot be run back-to-back without opening and closing the door. • If the fault will not clear, replace the door lock.
15	Water Temp Sensor Invalid	The thermistor is disconnected, not present, or has failed.	• Run Service Mode heater and thermistor test 20 to verify heater and thermistor. • Check thermistor resistance from connector J701 on the control board. Validate the resistance matches the table in mini-manual. • Check the heater resistance from connector J503 on the control board from pin 4 to 5. • Check wiring harness and connections. • Replace thermistor or heater if resistance is out of spec.
17	Dry Load Sense Timeout	Dry load sense times out and moves to the next part of the cycle selected. This occurs when the washer is not reaching the target speed within a defined time limit for the load type selected.	• Check for water in the bottom of the tub. If so, drain and try cycle again. • Check the basket for excessive friction. Basket should spin freely. If not, find source of friction and remove it. • This can also happen if a cycle is started with wet clothes. • Consumer education to doesn't load the washer with wet clothes.
18	Drain Pump Clearing Algorithm Failed	Pressure sensor indicates water in the tub after attempting to drain.	• Fill tub using Service Mode test 7 and check drain pump operation using Service Mode test 12. • Check drain hose for blockages. • Confirm standpipe height is within recommended guidelines. • If pump does not operate, check that the resistance of the pump matches resistance table and verify 120 VAC while pump is operating at J512. • Check pressure tube for pinches where it goes through top cover grommet. • Use pressure sensor test 10 to ensure correct pressure sensor operation.
19	UI State Timeout	This will happen if a cycle is paused for greater than 24 hours or if the pressure sensor reads greater than 0.5-in. while the machine is off for greater than 24 hours.	• Check for leaking water valves. • Use pressure sensor test 10 to ensure correct pressure sensor operation. • Consumer education on leaving sopping wet items in basket for more than 24 hours. • Pausing the machine for greater than 24 hours can cause this. • Can be caused by out-of-balance. • Can be caused by starting a cycle with the "no spin" option selected. • Check the output voltage from the pressure sensor to ensure it matches the water level in the basket according to the pressure sensor chart. • Check pressure tube for trapped water. • Ensure pressure chamber port is free from obstruction using drill bit size 1/16-in. by hand so as not to drill through the inner wall.
20	Critical Flood Level by Gallons	Water volume into the tub exceeded 41 gallons as calculated by the control. 1. Pressure tube is momentarily pinched, has water in it, partial blockage if Flood fault 12 occurs. 2. Low water pressure/ flow or permanent pressure system blockage if NO Flood fault 12 occurs.	• Check pressure tube for pinches where it goes through top cover grommet. • Check for any leaking water valves. • Check home water pressure. • Check the output voltage from the pressure sensor to ensure it matches the water level in the basket according to the pressure sensor chart. • Check pressure tube for trapped water. • Ensure pressure chamber port is free from obstruction using drill bit size 1/16-in. by hand so as not to drill through the inner wall.
22	Out of Balance (OOB) During Dry Load Sense	Large wet/OOB load being washed. This is set if OOB condition is detected during dry load sense algorithm. Dry load sense will be abandoned and wet load sense will be started.	• Check for excessively OOB load. Customer Education on how to distribute load. • Check the basket for excessive friction or for being excessively out of round. Basket should spin freely and without wobble. If friction is found, remove it. If basket is bad, replace it. • Check speed sensor for loose connection to the motor.
23	Critical Door Lock Failure	Cycle canceled due to inability to reach desired door lock state.	• Verify the door is closed properly, if door does not close freely, lift the door until it closes freely. • Replace door lock and door lock harness then run below actions. • Check the door lock using service mode spin test 14 to ensure door lock operation. • Verify that the door lock is not blocked by any external debris. • Check door switch continuity at J513 on the control. • Check continuity of door lock position. Opened or Closed. • Check for proper operation of door lock. 120 VAC while activating. • Check door lock wiring harness from the control to lock assembly.
24	Door Logic Failure	Door lock failure. This fault is set if the system perceives the door to be both OPEN and LOCKED for 5 consecutive seconds.	• Replace door lock and door lock harness, then run below actions. • Check the door lock using Service Mode spin test 14 to ensure door lock operation. • Check harness and connections from the control to the door lock assembly for damage and continuity. • Run a spin cycle. Pull up on the door during spin for more than 5 seconds and see if this fault occurs.
