AstralPool Unstable Inverter Control / Sensor Feedback Issue

Pump speed fluctuates on a variable-speed AstralPool pump even though a constant speed is selected.

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

Faulty speed sensor, Electrical noise on supply, Internal inverter control fault, Loose control wiring

Safety first: Turn off power before accessing control wiring.

Check supply stability: Have an electrician verify that the supply voltage is stable and within specification.
Inspect control connections: Ensure all low-voltage control and sensor connectors on the PCB are firmly seated.
Reset to factory defaults: Perform a factory reset of speed profiles and reprogram according to the AstralPool manual.

If speed instability persists, the inverter or motor sensor may require replacement by a service technician.
