Display shows H0 or similar code and the cooker does not heat properly.

Safety first: Ensure the cooker is on a stable, heat-resistant surface.

• Check program selection: Confirm that you have selected a cooking program (e.g., Rice, Soup, Pressure Cook) and not just Keep Warm.
• Cancel and restart: Press Cancel/Off, wait 1 minute, then select the desired program again.
• Factory reset (if available): Some Philips models allow a reset via a button combination (refer to the user manual). Perform a reset to clear firmware glitches.
• Sensor check: If H0 appears unexpectedly and food remains undercooked, the temperature sensor may be misreading. Professional diagnosis of the NTC sensors and PCB is recommended.
