    Hi,

    I have a Vaillant VCW 242E, when I switch on the hot water it heats for about 3-4 min's and then the water runs cold. If I switch the boiler off, then back on again and leave it for a while the water heats again for a few min's before running cold again.

    Anyone have any idea what this might be?

    Many Thanks,
    Steve

    First thing to check visually is that the diverter valve DHW demand switch is remaining made.

    We need to know exactly what it's doing when it's cut out. I don't think you need a Vaillant expert at this stage, just a little more info on what the boiler on what's going on at the time of the fault.
