Vaillant EcoTec Plus boiler whines until hot water is turned on and then stops

[Matthew Wilkinson]

So for a while, our boiler a Vaillant EcoTec Plus has made a whining noise, usually in the morning when it first comes on but can happen any time of the day (when on). The first time it happened I turned on a hot tap and it stopped. I have been doing this ever since, but actually, it is annoying and happens more frequently than I can ignore.

No error codes, alarms, loss of heating, hot water, and in fact was serviced shortly after it started happening, but I forgot to mention to the plumber at the time because it had only happened once or twice so I thought it was a glitch. Doh!

Any suggestions on a fix? Or is it a plumber job. I have insurance but if I can save the £60 excess, time and hassle then great.

Thanks in advance.

Nope I know what the fault will likely be but nothing you can fix yourself unfortunately. It's an internal boiler part on these thats responsible for this noise.

Will need to make the claim on your insurance and pay the excess for this one.

Put it this way. The part would cost you more than 60 quid.

Great, thank you!

Hi Matthew,

How old is the boiler? If it’s in warranty it might be something you can contact Vaillant about.

Thanks,

It's about 12 years I think. We bought the house 3 years ago. Pretty sure not under warranty.

It's about 8 years I think. We bought the house 2 years ago. Pretty sure not under warranty.

Yeah I don’t think it is, but worth asking. 🙂

How critical is it? Do I need to get it done ASAP or is it just an annoyance?

*** naughty naughty internal boiler part mentioned *** probably due to lack of servicing and or inhibitor. They're almost impossible to clean. Try putting some sentinel X800 or fernox F5 powerflush in the system.
