Possible Causes
Shorted pump motor windings, Water ingress into pump wiring connector, Damaged pump harness, Faulty control PCB
How to Fix / Troubleshooting
Safety first: Unplug immediately if you suspect an electrical short or smell burning. Do not continue to operate.
- Inspect for leaks: Check around the solution pump area, hoses, and connectors for signs of water leakage. Dry any visible moisture with a towel and allow the unit to air dry completely.
- Check wiring harness: If accessible without major disassembly, inspect the pump wiring connector for corrosion or loose pins. Do not pull on wires; only on the connector body.
- Do not bypass safety: Never attempt to bypass fuses or bridge connectors to force the pump to run.
- Service recommended: E5 typically indicates an internal electrical fault. The pump assembly and possibly the main PCB should be tested and replaced by a qualified technician.
