Heat Pump Keeps Tripping the Breaker in Northcliff
The circuit breaker or earth leakage trips shortly after the heat pump starts. This page covers how we diagnose and repair it on heat pumps in Northcliff.
This fault is normally treated as same-day work because the site has effectively lost hot water, steam or safe operation.
Hillside properties with long pipe runs, high static pressure and multiple geysers. Where a site runs on borehole water, hardness and iron content shorten service intervals considerably and are worth testing before setting a maintenance plan.
