AstralPool Intermittent Power or Control Fault

Pump runs but occasionally stops and restarts on its own without user input.

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Loose supply connection, Faulty timer or automation relay, Overheating motor thermal cut-out cycling, Intermittent control PCB fault

Safety first: Turn off power before tightening any electrical connections.

Check external controls: Inspect any AstralPool timers, chlorinators or automation systems controlling the pump for loose terminals or relays clicking off and on.
Inspect supply wiring: Ensure all connections at the pump terminal block and any junction boxes are tight and corrosion-free.
Monitor motor temperature: If the motor is very hot when it stops and restarts after cooling, the thermal overload is cycling due to overheating; address ventilation and load issues.
