British gas Boiler - CH not working

[yashyashm]

Hi All,

CH is not working Hot water is working fine. The signals and communication is all checked and ok between Thermostat (RC Plus) and WR1 Receiver. Red light blinks when i change the temperatire and when all done Green light is there. Batteries are ok at thermostat.
Flame sign is on the thermostat. But there is no ignition at the Boiler.

Any body please help what could be wrong please.

let me know in case of more inputs.

Ah yes, a British Gas boiler. Now I should know the exact model but............
Model please.

Thanks Pete for your quick reply.

There is nothing written on the Boiler. But looks like i got this one.

I reckon the issue is the receiver not able to ignite the boiler for CH.

Sounds like a faulty receiver!

any comments please ?

Is there anyway I can manually switch on the Central heating at the boiler (bypassing thermostat and receiver) ?

Possibly by finding the connection at the boiler where the receiver is connected, and removing the wires and fitting a bridging wire between the terminals. By doing that you have no room temp control to switch off the boiler. Get the receiver checked out, as these often fail. Make safe any disconnected wires.

I agree with Tony.

When the green light comes "on" on the receiver you should hear an audible click.

If no click is heard then the receiver is faulty. (very common on that receiver)

faulty - you mean the capacitor is not working.
does the replacement of capacitor will resolve the issue ?

Yes, if that's the cause as it often is.

But to diagnose the fault it needs the capacitor measuring first.

I have about 20 of those caps in stock!

They can be a little tricky to get off and refit in severely limited space!

i changed the capacitor with no luck !

can anybody please suggest what else i can try please ?

 

[Agile]

I said measure the value of the capacitor! That was to identify if it was the problem or not.

Now it seems you will have to replace the wireless stat.

 

[yashyashm]

you mean the whole stat or i can replace the receiver only ?

 

[Agile]

They have probably changed the frequency so it would need to be the same on both units. They are probably not marked though.

Its normal to change both units. May not be possible to buy just receiver.

BUT you don't know if its the receiver or transmitter at fault!!!

If you know the date which probably will be shown, their helpline should be able to tell you if current ones will match.

@scatmanjohn Hi, apologizes for jumping into a thread but I couldn't PM you, perhaps you can assist me, my Vokera synergy 29e gas boiler is showing error 07, this was an intermittent problem over the last few weeks but turning the switch to RESET usually sorted it out but now since yesterday the 07 code is not clearing & the boiler will not start, I checked out the 07 error code in the manual & it points to a faulty primary thermistor vokera part No 8484, does the system need to be fully drained to replace this part?...thanks
