Possible Causes
Failed timing circuit on main PCB, Corrupted cycle parameters, Power supply instability to control board, Faulty oscillator component
How to Fix / Troubleshooting
Safety first: Disconnect power before accessing the control board.
- Power reset: Unplug the unit for 5–10 minutes, then plug back in and observe if E20 returns.
- Check supply voltage: Use a multimeter to verify that the outlet voltage is within the range specified by Weasy. Avoid long extension cords.
- Factory reset: If supported, perform a factory reset to restore default cycle timings.
- Inspect control board: Look for obvious damage or corrosion on timing-related components (crystal oscillator, capacitors).
- Replace the main control board if E20 persists and other sensors are known good.
