Error Code FE

EXCESS ERROR

Also displayed as: FE

What This Means

Inlet Valve damaged (continues to pass water when closed); Main PCB (Controller) damaged; Hall Sensor faulty

How to Fix

1. 1

   Confirm FE error is displayed

2. 2

   Check if water is still flowing into unit when product is not running — if yes, water valve is closed but debris is causing leakage; replace Inlet Valve

3. 3

   Check Hall Sensor: verify wire connection; measure resistance — should be 9 kΩ ±5%; if out of range, replace Hall Sensor

4. 4

   Check voltage from Main PCB to Hall Sensor — should be DC 5V ±15%

5. 5

   If Hall Sensor is OK, check Main PCB: check voltage output; if voltage is out of spec, replace Main PCB
