Error Code FE

Excess Error — water fills above normal level; drain pump auto-activates

Also displayed as: FE

What This Means

Inlet valve stuck open or leaking; Hall sensor (flow meter) faulty; Main PCB fault

How to Fix

1. 1

   Step 1: Measure inlet valve resistance — should be 23-27Ω. If shorted or out of spec, replace inlet valve.

2. 2

   Step 2: Measure voltage at WH6 pin5~pin6 — should be 8V DC ±15%. If out of range, replace main PCB.

3. 3

   Step 3: Measure hall sensor resistance at NA8/WH4 — should be 9kΩ ±5%. If out of spec, replace hall sensor.

4. 4

   Step 4: Measure hall sensor control voltage — should be 5V DC ±15%. If absent, replace main PCB assembly.

5. 5

   Step 5: If PCB was replaced and FE error persists, replace hall sensor.
