Slightyly urgent: newish Worcester Bosch combi boiler. Hot water fine but heating not working!

[eekamoose]

Anyone happen to know if there's something fairly obvious I should be doing before ringing the plumber tomorrow morning?

TIA.

Am putting the dcs to bed atm. Back soon.

Has it got the wireless thermostat on one of your walls?

Yes.

Sorry, I should have started this thread later. Got to go now. Back in 15 mins.

Ours has just done the same. The control valve has got stuck on water only and isn't flipping over to Mixed or Heating only. We can manually trip it but have the heating engineer coming out in the morning

Are you there peggotty?

Hi i'm here! Just thought it might be something to do with the thermostat not being 'read' by the boiler. Is the blue light on the boiler on?
I don't actually know anything about boilers btw just had same boiler installed about a year ago...

could you have knocked the off button on the heating control pad

You are ringing bells Peggotty.

Think I made a note on the instruction manual how to reset the signal between the wireless thermostat and the boiler. Seem to remember it involved taking the batteries out.

Now, where is that instruction book?

Furball - do you mean inside the front cover of the boiler or on the thermostat thingy on the living room wall?

Aha! I really hope so. I can try and dig miy instructions out if you can't find yours?

Have you sorted it out eekamoose?

sorry I didn't come back last night. I meant the themostat control panel timer on the wall. It's quite easy to switch off either the heating or water button by mistake.

Yay, boiler engineer has been and gone and replaced the entire control valve. We are now toasty warm again.

Have you had any luck, eekamoose?

Oh, glad to hear you're sorted now rubberduck.

Thanks to peggotty and furball for looking out for me!

I found the instruction manual last night and spent ages trying to get the heating going again - but no luck. Went to bed with a jumper over my jim jams.

But this morning, for some completely unknown reason, the heating came on again. Hooray! . Now, however, I can't get it to go off!

So the plumber is coming anyway ...

Eekamoose is the little flame symbol on your boiler control panel flashing? If so, it has lost the connection with the thermostat. We had Bosch out to fix ours last night and the guy had the replacement part out of the box before we could even finish explaining the problem.

PS: In case you come back to this before the plumber comes and your flame symbol is flashing, you can over ride by pressing ok

It sounds like it could be the diverter valve which needs replacing! Hope the plumber can sort it out for you..

The good thing about worcester bosch boilers is that they give the engineer a little code to tell them what is wrong!!! It is like it has a voice so there should be none of this umming and ahhhing over what the problem is (hopefully)
