P2

Klarstein Pressure Sensor High Signal / Overpressure Detected

P2 error appears during cooking; cooker may overheat or shut down unexpectedly.

Safety Warning

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

Defective pressure sensor sending high reading, Blocked pressure sensor tube, Firmware miscalibration, Main PCB analog circuit fault

How to Fix / Troubleshooting

Safety: Treat P2 as a potential overpressure condition. Unplug the cooker and allow it to depressurize naturally.

Step 1 – Clean pressure path:

Clean the steam outlet, anti-block shield, and valves as described in other pressure-related fixes.
Ensure the pressure sensor tube (if present) is not blocked with food or scale.

Step 2 – Inspect sensor and wiring:

Unplug and re-seat the pressure sensor connector on the PCB.
Check for corrosion or moisture around the sensor.

Step 3 – Repair:

If P2 recurs even with a clean pressure path, replace the pressure sensor.
If the new sensor does not resolve the issue, the main control PCB is likely faulty and should be replaced.
