After turning on bathroom tap, i no longer can get hot water from my Ariston Euro Combi and the pilot doesn't come on but the radiators will work and when central heating is turned on the pilot is lit. No re-set button available. can anyone give me advice please?

It sounds like its the diaphragm on the diverter valve,but you should get some corgi reg ,to carry out the repair..
