Possible Causes
High water pressure, Faulty inlet valve not closing fully, Blocked pressure chamber, Incorrect installation of drain hose causing siphoning
How to Fix / Troubleshooting
Safety first: Turn off power and water supply.
- Check water pressure: Very high inlet pressure can cause overfill. Install a pressure reducer if household pressure is above Bosch recommendations.
- Inspect inlet valve: Ensure the AquaStop valve closes fully and is not leaking when de-energized. Replace if it drips.
- Clean pressure chamber: Remove and clean the side heat exchanger/pressure chamber if accessible. Blockages can cause incorrect level detection.
- Verify drain hose installation: Ensure the drain hose has a proper high loop and is not inserted too far into the standpipe, which can cause siphoning and confuse level detection.
