No hot water - Baxi Combi 105e

[mojo63]

I have no hot water on the above central heating system. The only way I can get hot water is when the heating is turned on. The radiators are working fine without the hot water but No hot water independently. Any suggestions what the problem might be and will it be expensive?
Thanks

Diverter valve isnt operating the flow switch. Its stuck r needs replaced. Part it self isnt too expensive

Oh, Really?

Could it not be something a lot simpler AND cheaper?

Sorry but thats what i meant when saying "stuck" sometimes they seize. Didnt want to go into much detail. The diaphragm isnt doing ist job are the flow switch isnt working. Either way he needs someone in to fix it. All you had to do was correct me

Check the microswitch is being made by the pushrod when tap is run, if the pin does not move or very little replace diaphragm as per instruction easy and cheap job will take a diyer 30 mins max.

Thanks for your help. I ordered diaphragm from ebay £5.75, which arrived today. I successfully fitted it and now have instant hot water independent from heating.
