Hi,

My 5 year old Biasi Riva Compact M96.32m boiler has started cutting out. A bit of fault finding with the manual pointed to the air pressure switch being an issue. I changed it and all worked for a few days but now I'm back to square one.

If I turn the hot water on the boiler starts up as normal humming away but no flame just an error light pointing out the air pressure switch. When I remove the internal cover to access the air pressure switch the boiler fires up as expected but as soon as the internal cover is replaced or very soon after being replaced cuts off again.

Any suggestions where the fault might actually be?

I've had a previous bad experience with a rip off boiler repair guy and i'd like to at least know what the fault is likely to be before I call in the the pros, or even better if its something I can fix.

Cheers
 
You've already exceeded your skill level, and no diy gas advice can be given. Read the forum rules. Opening the inner panel should be done by gas safe engineers.

Can you describe the "bad experience" for us?

The inside of the boiler is sealed to the room to ensure it is safe. That's why only gas reg engineers should be opening that part of the boiler.

What is the manufacture date of your boiler? Last four digits on the serial number. Shown on label on the flap over the knobs.
 
there seems to be a lot of rip off gas engineers about or is it tight a*s customers ? now that is the question;)
 
Thanks to the people who took the time to actually offer advice and not just resort to name calling I really do appreciate valid feed back. I don't plan to dig any further with the boiler as you rightly pointed out its passed my skill set now, I just wanted to know if it was something stupid and easily fixed before calling out an engineer.

As for forum rules I saw several other posts about air pressure sensors and figured it was a valid question. I figure they had to remove some covers too.

The name calling just makes me think are you guys old enough to be gas safe registered, seems like your 12 years old.

As for saving "pennies" I doubt any of you would work for "pennies". I should think its a fair bit more just for the call out plus without any prior knowledge of the issue I could be charged for pretty much whatever parts you want throw in even if its not related to the fault.

Sorry I bothered to try to research the issue and didn't just blindly call out an engineer. < sarcasm

I am surprised that with some experience of these boilers, you are not aware that the problem is usually NONE of those things you have listed.

You are new to this forum but before posting you should have read the rules first and would have seen that we are not permitted to give DIY advice on gas work. Consequently you should not have listed those possible causes!

We don't mind you researching, but we have to point out that you should not be opening up a room sealed boiler.

Even worse that on that particular model the combustion chamber cover can sometimes be very difficult to replace to remain gas tight.

There is only one place to properly diagnose boiler faults and that is in front of the appliance so none of us know what your fault actually is.

But what I can say is that on about 12 of your model that I have seen displaying the fault code for an air switch, NONE of them turned out to be caused by the switch.

In fact they were all a much more expensive part. I am surprised that Connor apparently does not know that.

Is there anything wrong with giving advice about possible reasons for the symptons a gas boiler displays along with the advice to NOT do any DIY work on the appliance.

How many plumbers who have blagged their way through to obtaining a "domestic gas boiler" tick on their GasSafe registration will go into "part replacement mode" as soon as they see a defective boiler because they cannot diagnose the actual fault. By not giving to the owner of the boiler some information about what the fault might be this forum is helping the blagged up gas fitter to make money out of the customer who, without advice, is ignorant and at the mercy of the gas fitter.

Some gas fitters who have obtained a ticket to work on domestic gas boilers may be incompetant in fault diagnosis.

Does the "domestic boiler" ticket prove that the holder has the ability to know how to safely close that part. Does the ticket prove the holder has had training on every type of domestic boiler ?

That said I do NOT advocate DIY gas work
 
Typical plumbers here thinking they know everything, parts are not always needed, always try the simple things before jumping in at the deep end, start from A and work to Z, This is why im a young engineer working for a company who Specialises in compaction repairs and has worked on hundreds of biasi boilers. No I will not be joining this combustion chamber group as I joined this forum to share advice and ask for advice when needed but my first comment gets slated :L forget it il go back to charging for my knowledge.
