I have a Vaillant Turbomax VUW242E boiler,Heating is ok but not getting any hot water. I have replaced the DHW Micro switch & diaphragm in diverter valve but still not working.
It will only work if i turn hot tap on & hold in the DHW microswitch.
Hi mate, going towards the divertor valve you will see some small copper tubes, take these off and rod them through with some electrical flex. They are blocked up with crap.
