Vaillant TURBOmax VUW boiler making "cracking" sound

[Deleted member 112128]

We started renting a house nine months ago.

The house is just over 20 years old and has a Vaillant TURBOmax VUW boiler.

The boiler seems quite old so may have been installed with the house?

It's regularly serviced but, as of two weeks ago, it started making a "cracking" sound most of the time that it's on.

Here is a link to an audio file of it: Vocaroo | Online voice recorder - https://voca.ro/eQt9U8i5vPi

Sounds like the fan, you’ll need a gsr to take a look at it.

Sounds like the fan, you’ll need a 'Registered Professional Gas Engineer' to take a look at it.

Thanks for your reply.

Thankfully, the landlords have a contract with British Gas HomeCare.

Called HomeCare earlier today and they're coming tomorrow, between 12-6pm.
