Only stops when switched off. No hot water coming in either.
Put new pressure swich on but still the same. Can blow down pressure pipe so not blocked. Help

umm... Youve done the sensible thing replacing the switch. Only other option is that its a programmer fault keeping the inlet valve on. If its an electronic programmer there may be a relay interface board between the microprocessor and valve which is shorted - trace the wiring back from the valve, look for shorts to the machine frame. check out www.2ndwave.co.uk/manual.html
