Cause
Water level too high.
When the overflow water level of 21kHz or higher is continuously detected for 3 seconds.
Note: In this case the drain pump will operate to drain the water automatically.
Solution
The pressure sensor frequency has exceeded 21.3kHz and is detecting an overflow of water.
DETAILS BELOW:
Check the water supply
Use test mode to check water level frequency
Is the water level frequency over 21.3kHz? (When adding water does your number increase on display?)
If no: does water flow continuously into tub with unit unplugged? If so, defective inlet valve.
If water is not being continuously supplied with unit unplugged
Is voltage being supplied to the inlet valve when power to washer is on, but no wash cycle is selected?
If yes: defective Main PCB.
If no: check for connection between Main PCB and pressure switch.
- If water level frequency is not being read (in test mode):
- Inspect for blockages and leaks in air hose between tub and pressure switch. Replace hose if needed.
- Check for lint accumulation in air chamber. Clean out air chamber.
- Re-check for error code.
If the error is still displayed, check the pressure switch - (It will have resistance of approximately 21Ω) and connections.
- (Also see Water supply error code).
Check the Pressure Switch
