How to Fix / Troubleshooting
Safety first: Unplug the coffee maker and let it cool before opening panels.
- 1. Descale and flush: Run a descaling cycle to clear any mineral buildup that may be affecting the flow sensor.
- 2. Prime the system: Fill the reservoir fully and run a hot water or rinse cycle (if available) to remove air from the pump and lines.
- 3. Access flow sensor: Remove the base to locate the flow sensor (often a small plastic housing in-line with the water tubing). Check for kinks or blockages in the hoses.
- 4. Inspect and clean sensor: If accessible, remove the sensor and rinse it under water to clear debris. Ensure the internal wheel (if present) spins freely.
- 5. Replace sensor if defective: If E3 persists and the pump runs but no flow is detected, replace the flow sensor with the correct GE part.
