Master Troubleshooting & Diagnostics Matrix
| Error Code / Indicator | Symptom / Meaning | Step-by-Step DIY Fix | Suggested Actions |
|---|---|---|---|
N/A | Water pump will not start / blows circuit breaker | Check: electrical connections, breaker, main switch, and earth connection. Check if the motor is hot (thermal breaker may reset when cool). Check voltage is present at the switch (bypass the pressure switch - if the pump then operates, the switch is faulty). Check the charging system for correct voltage (+/-10%) and a good earth. Check for an open or grounded circuit, motor, or improperly sized wire. Check for a seized or locked diaphragm assembly (water frozen?). | DIY Safe |
N/A | Water pump will not prime / splutters (no discharge, motor runs) | Check: filter isn't clogged with debris; there is water in the tank and no air has collected in the hot water system; inlet pipework isn't drawing in air at a leaky connection; inlet/outlet plumbing isn't restricted or kinked; correct voltage is present with the pump running (+/-10%); no debris in the pump inlet/outlet valves or swollen/dry valves; pump housing isn't cracked and drive assembly screws are tight. | DIY Safe |
N/A | Water pump will not shut off / runs when tap is closed | Check: output side (pressure) plumbing for leaks, and any leaky valves or the toilet; for air trapped in the outlet side (water heater) or pump head; for correct voltage to the pump (+/-10%); for a loose drive assembly or pump head screws; whether valves or the internal check valve are held open by debris or swollen rubber; pressure switch operation/adjustment (refer to the shut-off adjustment procedure). | DIY Safe |
N/A | Water pump runs noisily or roughly | Check: for plumbing that has vibrated loose; whether rigid pipework is transmitting noise; whether the mounting surface is amplifying noise; for loose or over-compressed mounting feet; for loose pump head to motor screws (3 long screws); with the pump head removed from the motor, whether the noise is from the motor or the pump head. | DIY Safe |
N/A | Water pump cycles rapidly | Check the pressure switch shut-off adjustment; ensure a water purifier (if fitted) is on a separate feed line; check for restrictive plumbing or flow restrictors in taps/shower heads. | DIY Safe |
N/A | Water pump leaks from the pump head or switch | Check for loose screws at the switch or pump head; check whether the switch diaphragm is ruptured or pinched, or punctured (water present in the drive assembly). | DIY Safe |
