I've just returned home after working away for a while and found I have no hot water.
I'm supplied by a Vaillant TURBOmax VUW 242/1E Combi Boiler, when I turn on any hot water tap the boiler doesn't flash up anymore and green light with tap next to it doesn't illuminate on control panel.
Can anyone kindly explain whats not happening, do I have a defective sensor of some description??
Many thanks
