I have a Worcester Greenstar 35 CDi. I have filled the system, but now can not remove the white plastic key - Can anyone tell me how to? many thanks

Is this a newer Greenstar CDi?

If so, turn the key back to the unlocked padlock symbol then pull downwards. The keys have O rings on, and they can be quite tough to remove, so give it a wiggle.

If you have to do it again, smear a little washing up liquid on the O rings. Makes it easier to insert and remove.
