Baxi Solo 2 40 PF needs PCB replacing?

[p_wallior]

Hi,

Since yesterday, I noticed that my boiler was making a repetitive noise. When I had a look, I saw the fan light coming on for a second, then going off, and continually cycling like that.
I found a thread on this forum that suggests that it is likely to be a faulty PCB.
I think I can replace it myself but can't find any information on the web about this appliance, also I am not sure of the exact part number.
I don't feel like taking the PCB just yet as it still works partially and it's too cold to be without heating at the moment.
Has anybody got a link to some instructions to replace the PCB on my Baxi boiler?
I think the part number I need is 232510 but I'm not sure, can someone confirm this?

Any advice is greatly appreciated!

Cheers,
Phil

I would check the aps first and the tubes connecting it to the fan. Also if it has the 90d elbow on the aps check this for being cracked.

Hi Dave,

Thanks for taking the time to answer.
What is the 'aps'? Sorry if it is a silly question.
My latest observation is that the boiler appears to have been behaving as normal for the last couple of hours so it's not doing it consistently.

Cheers,
Phil

Will be PCB if fan is cycling on/off/on/off quickly.

231711bax will sort you out.

APS= air pressure switch.

I bow to poxi's experience.

Poxi,

Thanks for the advice, any idea where I can find some instructions / manual for the Solo 2 40 PF? Are there any specific precautions to take when replacing the PCB?

Cheers,
Phil

Make sure all power is off to heating system as these have a permanent and switched live.

Also make sure you earth your self before touching the pcb as any static on you could damage the new pcb.

I only popped in to put the record straight on a post

Any electronics experts I have ever watched working always wear the earthing wristband and crocodile clip attached to earth electronic components I have always bough seem to be supplied in anti static bags.

Is this incorrect then?

Hi Dave,

I'm not a plumber but I work with PCBs on a daily basis. It is true that one should wear anti-static protections when handling PCBs as you could damage some components. In practice, I have never heard of a PCB being damaged through not using these precautions.
So yes you should wear a wristband to be completely professional but if you don't, just make sure you hold the PCB by the sides and avoid touching components, I doubt you'll ever cause any damage.

By the way, the PCB appears to have been behaving since sunday. I'll try to get a replacement PCB anyway as I wouldn't want to be left without heating all of a sudden.

Cheers,
Phil

Gosh, I have, and I've done it! Only particular types of components though like CMOS. Ordinary biopolar transistor low-tech stuff (as on a 231711, probably) is ok in my experience.
Don't scuff across a nylon carpet and touch a board - touch the furniture it's on first, so you're discharged.
If you put your thumb on the chassis first then your finger on the board, there's no way a voltage could be on your finger to surprise it.
