vaillant self help

 

Hello,

Well if you’re here, you must have a problem?

The idea of this page is to help you save a few quid, and save me e-mailing photos and instructions for simple faults that can put right without you having to pay a small fortune for someone to fix in a few minutes.

It’s a work in progress, so hopefully I’ll be adding information regularly.

Go here: “Vaillant Boiler Fault Codes” for advice or help if you have an ‘F’ showing in the display.

For example:    F28, F29, F22, F1, F0, etc etc....


There’s a video below on the basic functions of a TURBOMAX, and some photo’s that should help you fill up and pressurise the boiler if you need to.

I apologise now, Leonardo D’Caprio I’m not......

Regards Mark

Filling the system? or maybe you’ve got an F.22 code flashing in your eyes?

Check the gauge pressure, check the black needle is at least 1/2 a bar, or in the green.

If not, have a look at the photos below, and hopefully you’ll be able to work it out!

Insert the screwdriver head into both valves, and turn 1/4. You should hear water going into the boiler, and the gauge should start to rise.


When you’re in the green, turn both valves off.


Reset the boiler, and if it hasn’t been damaged by dry-firing, you should be up and away.

Some have square heads to turn, a bleed key is an ideal tool..

Some older models may only have one valve!
