How to Fix / Troubleshooting
Safety: Unplug the unit before any inspection. Do not attempt to bypass the sensor.
- 1. Reset: Unplug for 10–15 minutes, then reconnect and test. If E1 returns immediately, continue.
- 2. Visual inspection: Remove the inner pot and inspect the center sensor disc for physical damage, cracks, or signs it has been pushed down.
- 3. Check for liquid damage: Look for evidence of liquid intrusion around the sensor area or base vents. If present, allow the unit to dry for 24–48 hours.
- 4. Warranty consideration: If under warranty, do not open the housing. Contact Instant Brands support for sensor/PCB service.
- 5. Technician steps: A professional can open the base, verify continuity of the temperature sensor with a multimeter, reseat or clean the sensor connector, and replace the sensor harness if open.
