Error Code FE
Overflow Error — water level frequency exceeds 21.3 kHz, indicating too much water in tub. Drain pump activates automatically when FE is displayed.
Moderate
Address soon - your appliance may not work properly
What This Means
Air chamber or tube clogged (pressure sensor reads incorrectly); Inlet valve stuck open when power is not applied; Main PWB assembly fault causing inlet valve to stay open
How to Fix
- 1
Confirm FE is displayed.
- 2
Press DELAY WASH and SOIL buttons simultaneously and check if water level frequency is over 21.3 kHz. If NO → check air chamber and tube for clogging.
- 3
If frequency is over 21.3 kHz → check if inlet valve works when power is not applied. If YES (valve opens without power) → replace the INLET VALVE ASSEMBLY.
- 4
If inlet valve does not open without power but water still overflows → if inlet valve is open continuously when power is applied → replace the MAIN PWB ASSEMBLY.
- 5
Note: When FE is displayed, power will NOT automatically turn off (unlike other errors).
