Potterton Suprima. Runs for few hours then shuts down, red light.

Hi

Potterton Suprima I have to look at, red flashing light. Will not reset on button.

if it's switched off at the wall then switched back on it fires up fine and will run for a few hours no problem.

Goes off again, will not relight.

What would you be checking?

I'm thinking slow running pump, blocked feed maybe?

Aps?

thanks

These are known for pcb,s. if it's aps the fan would run but no ignition. Best bet is ring the tech help line up, but my momeys on pcb.

Thanks. I will check with technical, I have changed quite a few pcbs on these and the aps.

The cust did say the fan is noisy, if the fan is running slow could that cause this boiler to go off?

 

[Leo21]

Yes, but I don't think the earning light comes on. it just stops.

I spoke to Technical today. He said it can't be the PCB, said it's the asp but unable to test it as working intermittently.

Doesn't fill me with confidence.

PCB was changed 2 years ago, not that that counts for anything.

I have told customer I will go with pcb and aps and return whichever doesn't get used.

Have asked cust to pay for parts up front and I'd return part of non used part. I have done work for the guy (landlord) before, only a couple of small jobs. He will not be present at the property, he has paid ok in the past although only after a few phone calls asking for it to be paid. He has said he doesn't want to pay out so much in case I'm wrong. If I got it wrong and it was neither of these parts I would take the hit obviously.

I think that's reasonable as I don't want to take the risk of not getting paid.

 

[armyash]

He's just text me and said can I try the aps first and go from there.

I'm with Leo thinking more likely the PCB.

 

[Leo21]

I agree with me.

 

[armyash]

He's now asked me to get both parts after a lot of messing about texting back and forth. Now unable to order parts for tomorrow. City plumbing branch i use do not have in stock either. I'll try and see if anywhere else have them but will need to get lucky.

No matter what it is with these boilers just change the pcb anyway.

PCB fault these boilers are known for it, new board comes complete with wiring loom so they take a bit more tine to fit

Yeah I have changed a few of these.

Thing that is annoying on this is I can change the asp and it might be ok still temporarily but won't know if it's the pcb unless it packs up again.
