Your washer is equipped with Consumer Help Indicator (CHI) is our way to communicate a simple remedy for some situations that you perform without the need to call for service. The chart below describes the helpful messages you may notice scrolling on your display when you return to start another load. These messages will provide simple remedies you can quickly perform. To ensure that you see the message, the washer will scroll the message continually until you interact in some way with the controls.

“Ob” (Out of balance)

After the wash cycle, the clothing wasn´t evenly distributed enough to spin out the water. Redistribute the clothes more evenly in the washer and then run a Drain & Spin cycle

“Po” (Water took too long

to Pump Out)

Resume cycle or enter Drain & Spin. If water pumps out, then the clog has likely cleared. If water remains in the washer, check for clogged or pinched drain hose. This situation could be more likely to appear, over time, if the external drain hose has been extended or restricted

“H2O Supply” (Water not entering washer)

Check your house water supply. Did you forget to turn on one or both supply valves after installation or coming back from vacation? As soon as the message starts to scroll, the washer will initiate a 3 minute lock-out period. The washer controls won´t respond/change during this time. After the 3 minutes, you can begin your cycle again. If you try to bypass the lock-out period by unplugging the washer, the 3 minute timer will start over again.

“”CAnCELEd”

If your machine has stopped itself before the cycle completed, CAnCELEd will scroll in the display. On models without a display, the two furthest right LED lights will flash. This indicates that an error has occurred. Try to run a Drain & Spin cycle to see if it will clear. If it does not clear, call 800GECARES (800.432.2737), in Canada, call

1.800.561.3344 for service.

Lock Monitor

Lid lock didn’t occur

or lid lock signal not seen by control due to lack of connection.

 Check the resistance of the lid lock assembly.  Check the harness for open wires and or

connectors from the board to the lock assembly.  If lock assembly and harness prove good at the time of service, replace the lid lock assembly.

Lid Monitor

Control did not get lid 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.

 Replace control if this fault happens repeatedly.

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.  Check harness and harness connections from the control to the motor.  Verify hall sensor is connected to the main harness. Put washer in Service Mode and run Test 13. Spin Test. 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.  TCO should reset in approximately 45 minute. If TCO is tripped, make sure motor moves freely and that nothing is jamming it. Replace motor if it does not.
