Induction hob zone shuts down and shows E2 after a short period of heating.

Safety first: Allow the hob to cool completely and isolate at the mains before removing any panels.

User checks:

• Ensure there is adequate ventilation under the hob – check that cupboards are not packed tightly against the underside and that Caple‑specified clearances are respected.
• Clean any visible dust from ventilation slots around the hob using a vacuum with a soft brush attachment.
• Avoid running multiple zones at maximum power for long periods if the hob is installed above an oven that is also generating heat.

Technician checks:

• Remove the hob and inspect the cooling fan assembly – confirm it spins freely and runs when zones are active. Replace if seized or not powered.
• Check the NTC temperature sensor fixed to the induction coil or heat sink for correct resistance at room temperature and continuity back to the induction power board.
• Inspect the heat sink compound and mounting of power IGBTs/MOSFETs on the power board; poor thermal contact can cause E2.
• Clean dust from the fan and heat sinks to restore airflow.

If the fan and sensors test correctly but E2 persists, replace the affected induction power module.
