    Hi All and thanks for taking the time...

    Short questions are:
    - Does this fault sound common/simple?
    -Would you advise replacing, or paying an engineer to get fault fixed?

    I have read the 44 posts that come up on search but nothing doing...

    We are not capable of doing any work ourselves, and know better than to try :eek: !

    Our Vailant Turbomax was working fine when we had it serviced for the first time about a year after moving in. We only got it serviced ahead of a special day- filling a birth pool (all went well :D).
    To be clear, before the service it was fine but very soon after it developed the following habit:

    During a shower, usually if you have asked for (perhaps?) 'too many' changes in temperature or flow rate, it will cut out. It then shows solid red light- 'Burner Lock Out Indicator'. This we can reset- blue knob- and it will usually finish the shower for us. We think central heating is not affected. The best thing to do is not 'bother' it with adjustments during a shower, i.e, toilets, other taps etc.

    It will sometimes provide three 15 minute showers per day with no problems.
    Other days it will cut off part way through :mad: . Probably about 2 days per week it fails but with no solid pattern, other than limited to showers, but then when else do we ask for such a duration of supply?
    It never fails to start for water, or heating.

    This is not a whinge about the servicing engineer; we did put the above to him and he was O.K. about it, but said it was a coincidence. We got the distinct feeling he thought we were 'trying it on' in some way. Moving on...

    We know there are new more efficient boilers out there, but could do with hanging on to our circa £2K budget while employment/income hangs in the balance :rolleyes: . We have read some threads about people keeping these (good) boilers going for years and saving money overall.

    Thank you for reading, hope I covered relevant areas.

    Thanks for any help :)

    Their are several different models of turbo, does it have digital display? Or green knobs and row of indicated lights up the left hand side?

    This blue knob is confusing me.

    Blue knob? -Sorry it is a green knob that you turn to reset the boiler.

    Other query- it has 4 green knobs and a single analogue pressure dial on bottom right of boiler.
    No LCD.

    Sorry for colour confusion, am a bit crap with colours!

    Spoke to a engineer today- said it might be a blocked heat exchanger?

    Thanks for any input/advice.. :)
