Baxi Duo Tec 28 HE A Intermittent Noisy

[Albert Jones]

This boiler has had this fault for over two years. Many engineers have been but never when at fault. Many parts have been changed. When at fault it is generally when the outside temperature is very cold. The boiler is noisy and and never manages to raise the temperature high enough for hot water or heating. It did fault this morning, this time the it lit went off and lit again. There has never been a fault code. Please look at the videos. All comments very welcome.

I think your best giving Baxi a call and asking for a one off repair. They will nail the problem for you.

both videos just show boiler in hot water mode.

Baxi spent 2 years on visits under insurance and couldn't fix it. They changed most major parts. Eventually they gave back two years of insurance money, it's no longer covered and it's only 5 years old.

The house temp is set to 19, it faults in either mode or when both are called.

I hope you have kept all the details and documentation from Baxi over this.
You should be able to go to some sort of 'Consumer Affairs' organisation with the evidence and Baxi will be toast.

You can't sell a product, repair it continually under warranty or insurance and then return the money spent and walk away from your product and cancel the warranty on your product.
If this is the case, Baxi have admitted the boiler is a 'lemon' and have withdrawn themselves from their responsibilities to you and left you with a problem boiler - to fix at your expense.

I would send a letter to the Head of Baxi, if it were me

Baxi did refund 2 years worth of insurance £300. We should read the small print, Baxi said that if the fault had been reported once in every two months they would have paid half the cost of a new boiler.

baxi have a 5yr g.tee no fee for that time, so why did you pay for insurance? if they could not fix it, under g.tee they will and do replace boiler f o c

The boiler only came with a 2 year guarantee it was then covered by Domestic & General. It was originally fitted under the warmer homes government scheme. I see all new Baxi's come with 7 year guarantee.

I have come to the conclusion (because it only plays up when it's extremely cold) that the problem is caused by the temperature of the cold water entering the boiler. The gas meter and governor, the flow switch have been changed and the condensate waste has been checked. The heating works fine. Any ideas as to what in the boiler is playing up under these conditions.

Thanks for your thoughts, the PCB has previously been changed. Have just change both NTC's waiting to see if the fault re-occurs.
