CE90 is Drum themistor abnormal
Check the drum themistor & connector...
Swap process unit, if still giving same error, probably LGC board issue

did whoever set it up, remove packing bolts from the back? is it leaking from hoses on back of washer, or from internal? check front panel on lower left from of washer. is filter accesses tight?

There are only themostat and themistor on the fuser unit.
If C440 sign on frequently, probably the themistor is deformed, which need to be replaced.
For 1st C440 sign on, try to reset it by entering 08-400, change the value appear on screen to "0", then reboot machine, if the machine is working, just leave it.
If not, C440 will sign on again, then only u replace the themistor.
To replace it very simple, take out the fuser unit, reverse it, and u will see a black plastic compartment, open it up, and u will see the themistor.

Humming can indicate a stalled motor...If a coin is jammed in the pump impeller it will often do what you describe...Check via pump filter access door...Good luck....Nomess

either drain pump itself is broken or something jammed in between the pump housing and pump impellor. the drain hose itself or pump cleanout cup (behind lower left access panel) may be clogged too.

Please specify the make and model of your unit.
If this is a LG inverter model.
The six flashes of the indoor unit light indicates a CH 06 alarm.
This alarm state indicates that the indoor unit pipe temperature sensor has measured a temperature out of range or the unit is protecting itself from this low temp state. Indoor unit coil temperature to low. Should it have reached a temperature of -5°C for longer that 30sec it will switch the machine off.

It could indicate that the unit refrigerant charge is too low or the sensor has gone out of calibration.

It should measure 5kΩ @ 25°C

I replaced the seal on my mother-in-laws LG washer last month. The seal has 2 bands. One that the attaches to the drum, and one that attaches to the front of the washer. The hardest part about replacing the seal, is gaining access to the seal. Once you gain access to the seal, it can be a little tricky getting the bands back on, because you have limited area to work. There is no special tool or tricks to get it back on, just persistance.

i drained it first with the pull out hose in the access panel on the bottom left. i tilted the washer back to remove it from the bottom.

The thermistor is located in the sump assembly next to the heater element.  The only way to get to it is to remove the dishwasher, turn it on it's side, remove the bottom panel to gain access to it.  Before you do that, remove the front door panel to gain access to the wiring harness.  About 1/3rd the way up from the bottom of the door, check to make sure that the wiring is not cut or damaged.  If you do find a broken wire, repair it and it should run fine.  Rarely does the thermistor go bad.  Good luck.
