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
