Hello Guys,
I've got a problem with a VCW242EH Vaillant boiler. It runs the radiators ok, but just provides luke warm DHW. I've checked the pump and diverter, which look fine. When the DHW is running flat out the water on the boiler side gets very hot, but the DHW doesn't seem to be picking up any heat from the boiler. I'm fairly happy that it's the heat ex playing up, but I'm unable to check the DHW sensor. Has anybody had a problem with the sensors, or a resistance chart etc to check the sensor? Also has anyone got a number for the heat ex so I can see which ones will fit.
Thanks, in advance, Col.
