    if it is the timer you will have to replace it, they are around the £50 mark you might get cheaper on ebay

    "timeswitch 150 manual timer.."

    this is one with the rotating dial, and tappets? Very popular with older householders because they are so intuitive in use?

    Sometimes the tappets don't seat well, for some reason they don't go into their notches properly. You could give them a wiggle.

    As they age, the "clockwork" mechanism does seem to get noisier.

    Post a pic of your one to be sure.

    With luck it will have the standard backing plate making it easy to swap in a replacement.

    There are a few on ebay, but a used one might not be much better than your own

    What do you mean by that, if that is a pic of your clock they are lined up correctly

    Yes the clock is more or less lined up proper, although the hour hand which is painted on the dial , doesn't line up exactly, ie 9pm...the minute hand will be at 12 and the hour hand just below the 9...but more importantly if I set the boiler to come on say 8pm to 12pm..it doesn't switch on at 8pm, could be well after 8 or even before..anyway got a new one from ebay coming so will see how that works

    they are easily fitted, the motors get weak with age and sometimes just get noisy but sometimes struggle when approaching the on times to push past the tappets

    Lol...correct!
     
  11. If that pic is yours:

    Time noted when you posted pic - 11:23 am, time set on that time switch around 00:23, I would say your clock is set wrong. Turn the clock to the correct time in the direction of the arrow and try that, if it still messes the time up then needs replacing. You also have it set to come on at 19:00 until 02:00 and 10:00 - 13:00

    Info you’re unsure about using it :https://www.vaillanthome.co.uk/download/timeswitch-150-user-manual/

    Ok guys just an update..I bought a new timeswitch 150..straight forward to fit...how come the boiler won't switch on when on timer mode,?...I set it come on from 1pm to 3pm by pushing the pins in..,but it fails to come on...any ideas?.. 20190528_151900.jpg

    Sorry just read above post ...what do mean my time is set wrong?..is it correct in this pic?
     
  13. It looks like it is. Is you roomstat turned up? Is the heating dial up on boiler?

    Time on first pic, it wasn’t set to correct time, so wouldn’t come on at correct time. The little triangle denotes where the time should be.
