E5 error appears, cooker stops heating or will not start pressure programs.

Safety first: Unplug the cooker and ensure there is no pressure inside. Open the lid only after the float valve has dropped and steam has fully released.

• Clean pressure path: Remove and clean the steam release valve, anti-block shield, and any removable pressure cap components according to the Philips manual. Food blockage can affect pressure readings.
• Inspect sensor tube: Some models use a small silicone tube from the lid or chamber to the pressure sensor. Check for kinks, blockages, or disconnection (only if accessible without disassembling sealed parts).
• Dry internal moisture: If the cooker has boiled over, moisture may have entered the sensor area. Allow the unit to dry with the lid open for several hours.
• Test non-pressure program: Try a non-pressure program (e.g., Sauté or Bake). If it works but pressure programs show E5, the pressure sensor is likely faulty.
• Professional repair: Replacing the pressure sensor requires opening the housing and disconnecting it from the main control board. Due to safety implications with pressure control, this repair should be performed by an authorized Philips service center.
