Mend Bosch 350 Combi Boiler

How do I repressurise my Worscester Bosch 350 Combi boiler?

Can anyone tell me how to repressurise my Worscester Bosch 350 Combi boiler? Low pressure (red light) is on after I bled a couple of radiators this morning - it is sitting on zero. I am pretty sure I just need to repressurise - just can't find anything in the 3 manuals I have!! My 2 year old son and I are pretty cold tonight, if anyone can help! Thanks, Megan. 17.03.2006

these boilers need a plastic key which is inserted under the boiler on the left hand side this key bridges the gap so when u turn open the filling loop it flows into the heating pipes then pressure it up to 1.5 bar and bleed the rads again then recheck the pressure.

you will need to refill the system .there should be a fill loop under the boiler to fill it up you open the tap and fill up until the presure gauge needle goes up to the mark
