Hello folks,
I am a new user and this is my first post. Am also not really technically minded.
I have a Vaillant 612 ecotech boiler installed. Was new 3 years ago and has worked perfectly until the last few weeks.
After I fitted in a new washing machine noticed that a few drops of water were leaking from bottom of boiler. Was advised that water pressure was too low. Released some water from nearest rad valve and pressure now correct and leak stopped. However since then water from taps does not get hot, only lukewarm. only heats up if the CH and water are on at the same time. If only hot water switched on the flame does not ignite although no error codes shown to reflect this. The CH works fine and heat up the rads. Only the water is lukewarm.
Any thoughts anyone pls. Have read similar posts here which mention heat exchanger, defective hot water thermister and stuck diverter valve
