A dead pool pump is one of those faults that sits awkwardly between "pump problem" and "electrical problem" — and knowing which it is saves you calling the wrong person. Here is how to tell.
First, what is it doing?
- Completely dead, no sound? Likely electrical — a tripped breaker, failed timer, or no power reaching the pump.
- Trips the power when it starts? Electrical or motor fault — often moisture or a perished cable in the motor.
- Humming but not spinning? A seized motor or failed capacitor.
- Running but weak flow? More likely a blockage, air leak or basket issue — a pool-side mechanical problem.
Check the simple things first
Confirm the pool timer is actually calling for the pump to run, and check whether the breaker or earth leakage in your DB board has tripped. If resetting it holds, great; if it trips again the moment the pump starts, stop — there is a real fault.
Why a tripping pump is a safety issue
Pool pumps sit near water, so an earth fault in the motor or cable is genuinely dangerous. Repeatedly resetting the earth leakage to force it on defeats the protection that is there to prevent a shock. It needs tracing properly.
Compliance matters here
Pool equipment must run on a correctly earthed, protected circuit — and it is a specific focus of an Electrical COC inspection. Non-compliant pool wiring is a common COC failure and an insurance risk. We diagnose the circuit, timer and motor and put it right. See electrical fault finding or book a callout.
