E6 error appears immediately when trying to start any program; no heating occurs.
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
How to Fix / Troubleshooting
Safety first: Unplug the unit before any disassembly. Internal components carry dangerous voltages.
- External reset: Unplug the cooker for 10 minutes to clear any transient fault. Plug back in and try a non-pressure program like Sauté. If E6 appears instantly, the fault is likely hardware-related.
- Check for burning smell: Smell around the base vents. A burnt odor suggests a failed heating element or board component.
- Visual inspection (advanced): If out of warranty and you are qualified, remove the bottom cover. Inspect the main heating element ring and wiring for burns or breaks. Check the thermal fuse mounted near the heater for signs of failure.
- Board inspection: Examine the main control board for burnt spots near the heater triac/relay. Do not touch components while plugged in.
Because this error usually indicates a failed heater circuit or control board, replacement of the main heating element or control board is typically required and should be done by a professional.
