Possible Causes
Shorted drain pump, Failed triac or relay on PCB, Short circuit in pump wiring, Moisture on control board
How to Fix / Troubleshooting
Safety first: Unplug the appliance. Do not repeatedly reset if a short is suspected.
- Inspect pump and wiring: Check the drain pump and its wiring harness for signs of burning, melting, or moisture.
- Test pump resistance: Measure the pump coil resistance. A very low reading or short to earth indicates a defective pump.
- Replace pump if shorted: Install a new Grundig-compatible pump if the old one is shorted.
- PCB inspection: If the pump is good but E23 persists, the pump control triac or relay on the main PCB may be damaged and require board repair or replacement by a technician.
