Vaillant Turbomax VUW 242/282E - Dodgy reset control

[geoffs46]

Hi,
The reset control on my Vaillant boiler spins round and does nothing, rather than resetting the boiler; does anybody know if it locks via a grub screw or in some other way - also how to replace it and where to find a replacement, if necessary?
Thanks in advance

The knobs snapped u will need a new one, u can ( if ur competent) turnthe power off an swop it for one of the others for the time being so u can reset it

Thanks Bunnyman - 15 minutes and hot water is restored; cost = absolutely nothing!
That's my kind of plumber.
If anyone happens to be scrapping a similar boiler - I'd gladly pay for a spare reset (or any other) knob.
Thanks again.
