Polaris Preheat / Pressure Detection Failure

Time countdown does not start; cooker stays in preheat indefinitely without building pressure.

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

Pressure sensor not detecting rise, Persistent steam leak at lid, Faulty temperature sensor preventing transition, Insufficient liquid

Safety first: Allow the cooker to cool and depressurize before inspection.

Check liquid level: Ensure adequate water is present.
Inspect lid seal and valves: Clean and replace worn sealing ring, float valve gasket, and steam release valve as needed.
Pressure sensor test: If mechanical seals are good, test or replace the pressure sensor module.
