Possible Causes
Inner pot not seated properly on heating plate, Deformed or non-original inner pot causing poor contact, Excessive food stuck under pot blocking sensor, Faulty thermal fuse or thermostat on heating plate
How to Fix / Troubleshooting
Safety first: Unplug the cooker and let it cool completely before inspection.
- Check pot seating: Remove the inner pot, clean the bottom of the pot and the heating plate. Ensure there is no rice, beans, or debris between the pot and plate. Reseat the pot firmly and evenly.
- Use original pot: Make sure you are using the original Redmond inner bowl or a compatible replacement. Non-original or warped pots can cause uneven heating and trigger E3.
- Avoid dry heating: Never run the cooker empty. Add the minimum required liquid and food before starting a program.
- Inspect thermal fuse/thermostat: With the bottom cover removed, locate the thermal fuse or bimetal thermostat attached to the heating plate. Check for signs of overheating or discoloration. Test continuity with a multimeter; an open fuse/thermostat must be replaced with the same rating.
If E3 appears immediately even with correct pot placement, the temperature sensing or control board may be faulty and should be checked by a technician.
