Grants vortex combi

Hi
I have hot water but no heating. I've changed the pump but still nothing. It works fine when I plug it into a plug top I've checked the check valve and it seams fine. I switch the heating on at the programmer and the ch heating light doesn't come. It's doesn't flash or anything. the boiler is 1 1/2 years old

It should be under warranty so I would give Grant UK a call.

Would help with which model it is too.

 

[Karkus78]

The guy fitted it himself. My friend is renting his house while he's away so I doubt he registered it. It's a 26 model

 

[leakydave]

It could be a 'controls' problem more than the boiler itself. Is the wall stat and programmer sending power to the boiler to call foe heat? Is the red LED for CH Pump coming on?

 

[Karkus78]

No no ch light is coming on

Follow the fault finding chart in the M.I's. If you do not have the book, download it from Grant website.

 

[Karkus78]

I have and the book says if the ch light is flashing it will be the pub but it's not flashing. How would I know if it was the controls

 

[DaveHerns]

I think your friend should get a RGI to fix it and send the bill to the landlord. He might find out the whole installation is putting him at risk

 

[bernardgreen]

I think your friend should get a RGI who is competent in repairing the Grant range of boilers to fix it and send the bill to the landlord.

 

[leakydave]

You don't need an RGI for an OIL Boiler! I don't think the controls are telling the boiler that heat is required. Get an electrician to check the wiring to work out where the fault is... either room stat or time clock I reckon.

 

[simond]

A boiler tech who can't do controls is no use to anyone.

Why would you call an electrician, most know nothing about boilers and controls. You are just setting yourself up for two bills rather than one.

 

[Karkus78]

Yeah I agree. I am a plumber but haven't done that much boiler servicing but I'm sure I'll figure it out. Yeah it's like the boiler isn't receiving the signal from the programmer. They don't have a room stat so I'll just change the programmer and see what happens

 

[James1991]

Instead of renewing the programmer, try linking the switch wires on the back plate first.

 

[Terrywookfit]

Try checking for fookin voltages at boiler

i think you should stick to plumbing leave the boiler to rgi , what do you mean ' i haven't done much servicing ' why are you servicing boilers being just a plumber. link at the back plate or check voltages at boiler , have you got a multimeter ? the fault finding chart is only a guide don't take it as gospel
