How to Fix UC Error

Unplug washer for 30 seconds to reset PCB memory and clear transient fault.
Verify dedicated circuit not shared with other appliances causing load fluctuations.
Check outlet wiring for loose neutral connection (major cause of UC errors – measure neutral-ground voltage <2V).
Test noise filter DC96-00488A input/output voltage drop under load (should be <2V difference with 10A load).
Replace noise filter if excessive voltage drop or physical damage present.
If error recurs within first minute of cycle: replace main PCB DC92-01543A (faulty voltage monitoring IC).
Install line conditioner if household voltage fluctuates >10% during operation (common in rural areas).
