Error Code FE

Bubble / Overflow Error

Also displayed as: FE

What This Means

Inlet valve damaged (not closing properly); Controller (main PCB) damaged; Hall sensor faulty (after PCB replacement still shows error)

How to Fix

1. 1

   1. Test inlet valve for proper closure. Measure resistance (23-27 Ohms). If valve is stuck open or resistance is out of range, replace inlet valve.

2. 2

   2. If inlet valve tests good, replace main PCB assembly.

3. 3

   3. If error persists after PCB replacement, replace the hall sensor.

4. 4

   4. Allow automatic drain pump operation to complete before further diagnosis.
