How to Fix / Troubleshooting
Safety: Unplug the washer before inspecting electrical components.
- 1. Check outlet: Verify the washer is plugged into a properly grounded outlet. Test voltage with a meter; it should be within local standards (e.g., ~120 VAC in North America).
- 2. Inspect power cord: Look for cuts, burns, or loose connections at the terminal block.
- 3. Reset power: Unplug for 5–10 minutes, then reconnect and try again. If E PS returns, continue.
- 4. Internal inspection: Remove the control panel and inspect the main board for burned components or bulging capacitors.
- 5. Replace control board: If visible damage is present or voltage tests confirm a failed board, replace the main control. This is often best handled by a professional.
