on light comes on water light comes on but when i turn on the tap on light starts flashing and nothing happens probable cause please

no CH
no DHW
i would first check to see if the CH & DHW flow switches [FSW] are operating
if the pins on the divertor valve are moving FREELY in & out under demand to operate the FSWs then the problem could be the microswitch in the FSW or the PCB
if the pins ARENT moving could be rubber diaphragm has split inside differential valve
quite easy to replace
