Vaillant Turbomax problem

rachel_and_jim · 21 Feb 2005

We have a Vaillant combi-boiler, I think it is the Turbomax model.

The boiler does not give us hot water on demand - sometimes we can wait ages to get hot water. And the latest development is that we have lost central heating altogether!!!!

Pressure seems fine - can somone tell me some simple steps to get it working again in non-technical terms?

I am on my way home now, will return here with more symptoms.

Many thanks in advance to anyone who can help. It's going to freeze tonight!!!!

Is it the turbomax pro or plus, if it's the plus is it showing an error code on the lcd display.
Failing that is the fan, pump running etc, if they're all ok it may be the divertor valve.

which turbomax

rachel_and_jim · 21 Feb 2005

It's the Plus. No fault codes and the pressure is fine.

At the moment the boiler is turning itself on and off in bursts of a few minutes. Most of the time the yellow light is failing to turn on but when it does, the temp goes up to the desired level but then falls right back down again. when this happens the radiators warm up for a short time. then it's back to being tempremental.

How do i check if the fan and pump are working?

What is your pressure reading on the gauge?

The pressure is at the high end of the green safe range.
