Possible Causes
Stuck external relay, incorrect wiring between Onga pump and controller, failed internal control relay
How to Fix / Troubleshooting
Safety: Isolate power before accessing control panels.
- Manual test: Bypass the timer or automation by plugging the Onga pump directly into a known-good outlet (if plug-in type) to confirm pump operation.
- Check wiring: Verify that control wires are connected to the correct terminals as per Onga and controller manuals.
- Inspect relays: Listen for relay clicks in the controller when switching. A relay that does not click or is stuck may need replacement.
Because this involves mains wiring and control logic, have a qualified technician correct wiring or replace faulty relays.
