Excess Error — water fills above normal level (drain pump operates automatically)
Moderate
Address soon - your appliance may not work properly
What This Means
Inlet valve damaged; Controller damaged; Hall sensor faulty
How to Fix
- 1
Check inlet valve resistance: should be 25 ohm ±5%; replace if not
- 2
Check voltage between WH6 pin5-6: should be 8V DC ±15%; replace main PCB if out of range
- 3
Check hall sensor resistance: should be 9 kΩ ±5%; replace if not
- 4
Check voltage between WH4 pin4 and NA8 pin1: should be 5V DC ±15%; replace main PCB if out of range
- 5
Replace main PCB assembly if all checks pass
