Possible Causes
Leaking plate heat exchanger, Failed pump seals, Loose union on hydraulic block, Corroded primary pipework
How to Fix / Troubleshooting
Safety: Turn off power and close the cold water and heating isolation valves. Water inside the casing can damage electrics and create shock risk.
- Remove front cover: Carefully remove the casing and use a torch to locate the source of the leak. Do not touch live components.
- Check visible unions: Look for drips at compression joints, pump unions, and the plate heat exchanger connections. Gently tighten accessible unions by a small amount if clearly loose.
- Do not operate with leak: Do not run the heater until the leak is repaired and all electrical components are dry.
- Professional repair: Replace leaking components (plate heat exchanger, pump, or pipework) via a qualified engineer.
