Possible Causes

Open-circuit main heating element under inner pot, Burnt relay or triac on main control PCB, Loose spade connectors on heating plate terminals

How to Fix / Troubleshooting

Safety first: Unplug the cooker and wait for it to cool. Do not attempt live testing unless you are qualified.

  • Check inner pot and lid: Ensure the inner pot is installed and the lid is correctly closed; some models will not energize the heater if the lid sensor is not engaged.
  • Inspect heating element connections: Remove the bottom cover. Locate the two main wires going to the heating plate. Check that the spade connectors are tight and not burnt. Reseat any loose connectors.
  • Test heating element: With a multimeter, measure resistance across the heating element terminals. A typical value is between 20–60 Ω. An infinite reading indicates a failed element that must be replaced.
  • Check for burnt components: Inspect the main PCB for burnt relay contacts or a damaged triac controlling the heater. Any visible damage usually requires PCB replacement.

If the heating element tests good but E7 persists, the main control PCB is likely faulty and should be replaced by a professional.
