Potterton performa fan fault

[armyash]

Hi everyone,

I am going to look at a performa this evening. The customer called this morning, said its showing fan fault and he's 'narrowed it down to pcb or fan'. Sounds like he is going to be great, he has wired up loads of boilers apparently.

What checks can I do to test the components? Does anyone know what readings I should be looking for on the fan?

Any readings for the aps?

Is there a way to tell if the pcb has had it?

Anything else to look out for?
Thanks.

OK I have been to have a look. Customer wired up a slave lead to the fan, it works, same with the pump.

Flame ignition and fan/flue fault lights both flashing.

Reset the boiler and turn on tap to create a demand and boiler locks out immediately. In approximately 1 second.

Have you had the boiler apart? Condensate blocked?
Ionisation sensor Burnt out?
Gas valve ( connect manometer to inLet to test)
TBH , if he has mucked about with it, could be anything!

Thanks for the reply.

Condense was clear.

I don't do a lot of breakdowns. I don't really want to go back because he is adamant it's the pcb. I'll tell him to buy the parts he thinks it is and I'll fit them.

Where would I find the Ionisation sensor?

Which Performa? How old?
They've been around for 20 years ish.

Gc: 17.393.13

Its never been serviced.

Signs of multiple old leaks inside.

Coming out with we will get it relaced in a few months and you can do it. Not particularly interested.

Found this broken clamp on the fan also.

I'm going to call baxi today and see if they can help if not will tell him to go elsewhere.

Cannot find that GCN

Fix the clamp on the flue. If it can pull air in there it is not pulling it through the Combustion chamber. This could cause over same results as gassing. It would most likely show as a fan/airflow fault.

I have not seen it so I could be wrong!

 

[armyash]

Sorry its 47 393 13.

Yeah I have said to him that clam could be causing it so would need to replace and go from there. He said its been playing up for about a year and has needed resetting regularly. Can't see it ending well for me if I get too involved.

New boiler

To check it, ali foil tape the gap, try it out. If it works, take the tape off and repair the clamp. Its only a bit of sheet metal. Make a new one.

If it isn't that at least you've ruled it out. Take it from there.

Clamp and board for me that one.

 

[armyash]

Thanks for the replies.

I'm going to call the customer now and suggest new clamp and pcb but will say as he has told me it's been working intermittently for the past year there could be other faults.

I'll probably take an aps also.

He's been an electrician for about 40 years, he has changed parts on the boiler in the past, diverter and microswitches.

I know what he is up to, as its been playing up but he can't put his finger on it, he wants me to take the hit for the pcb if it still doesn't work.

The boiler goes to lockout immediately the second there is a demand.

 

[armyash]

He has phoned me and said he wants a pcb and new clamp.

I have made it clear that there may be multiple issues.

If you want to swerve this job can you not advise him ( if they still do it) BG one off repair? Said he will replace in a few months let them sort it and leave your number for the replacement install...lol regards Turnpin

The one off repair is when they sign up to a 12 month contract from what I remember.

LOL.. I still might suggest that.

I have replaced quite a few pcbs on these boilers and I've been right. Had a couple of fans too. If he hadnt been messing with it, and putting doubts in my head I'd go for pcb just because the boiler does absolutely nothing before it locks out.

This is a walk away job ! he has been messing around inside boiler cant fix it and now wants to place the blame in your hands, Mate if you touch this one your leaving your self wide open for a big hit on parts . You have got to learn to say no to these kind of jobs, He took it apart tell him it his problem , quote for new boiler only

Or charge him for the repair, inform him that because he has messed with it the pcb may not fix it (like you have) and charge for a full commission and go through it with a fine comb.

 

[armyash]

Just sent his text to him, will await reply.

Can you edit the picture to not contain his number or postcode? You might need @ShaunCorbs to do it for you.

Sorry I didn't even think about that.

It can be deleted completely if needed.

Turned out to be the pcb so all sorted, the customer was happy and relieved.

It is mostly always the board on these from my own experience mate

 

[ShaunCorbs]

Did he tell you I told you so

Me or the custard?

Cus

 

[Harvest Fields]

Cus

Just checking. I’m trying to get out of that habit.

 

[armyash]

Haha he was sweating, he text me before and said bring a gas valve as well just in case!

I said once opened they are not going back and if all parts are used with labour on top you're not far off a budget boiler.

He gave me a big high 5 when it fired up
