Filling Key Stuck in Worcester Bosch 24i Junior

[jonmc1980]

Hi, all after re-pressurising my system the filling key is stuck fast I'm wary to put too much pressure on it as it may snap off. I've never had a problem with it in the past. Can someone please answer these questions.

1) Is it safe to use the boiler while the keys still in?
2) Is there any reason why I can't just leave the key in?
3) Can anyone provide any advice for getting it out?

Thanks in advance for your help and advice!

Yes it is safe enough to leave it in place and cant think of any reason why you can not remove it if you are operating it correctly

Thanks for the reply Ian, it just seems to be stuck fast its always been easy in the past. I just turned it to the unlock position and it slid out easily... Not anymore...

I leave them in for customers as they can be a pain, so long as you turn the white square screw off then you'll be fine

which key do you have ? there are 2, a large one and a smaller one , if it is the origional charging link that came with the boiler will more than likely be the larger one, can only think that one of the O rings has split and is jamming and stopping you from removing it, you should have another valve that you need to operate though in order to top the pressure up so as long as this valve is closed then you will be OK

Its the large key that I have. The filling valve is working fine so I'll just leave the key in place. Thanks for the advice!
