What does error code E 16 mean on a Warmhaus LAWA 18 Boiler?
- JJames HullSep 4, 2025
If your Warmhaus Boiler displays error E 16, it means that the central heating RETURN temperature sensor is faulty. The suggested solution is to contact an authorized service. Also, check for intermittent or open contacts on the harness carefully. Check the RETURN central heating temperature sensor resistance. Check the cabling and connectors between the RETURN NTC and the board. Finally, reset and restart the boiler.
