Overflow on Worcester boiler gushing water

[simple]

What it says really.

I've just bought a flat and finally after getting the electric connected, I went to fire up the boiler. The water and gas was turned off so I turned the water on at the mains and also two leavers, one red, one grey, on the water inlet pipe to the boiler which seem to be on a loop.

I can hear water rushing through and then the next thing there is water rushing out through what I'm guessing is an outside overflow pipe. I'm on the second floor so it was pretty loud. If I shut the grey leaver off the overflow stops, but then so does the water to the taps.

I've never had mains gas before and whilst I'm quite practical, I can't figure what is happening. I can't find anything in either the owner's manual or the installation manual. I'm assuming it is broken somehow, but mindful that I have never used a gas boiler before, it is possible I'm just doing something stupid and not turning it on properly. So, am I being a doofus and just not turning it on right or do I need an engineer?

Thanks in anticipation

will do tomorrow. The flat is not really habitable at the moment so I'm staying with friends. Will take copious pics tomorrow

dont open any valve that is connected to a metal braided hose, as thats the filling loop

oh sugar, I think the grey lever was connected to a braided hose.

there should be a pressure gauge on the boiler, at cold should be just over 1 bar

if its like 2-3 bleed a rad until it drops to around 1 bar

Should I do that with both levers turned to on?

When I actually turned the boiler on, it was at 2-3. Looked too close to the red and with all the water gushing I turned the boiler off and turned the grey lever to off as well. One thing I noticed was if the grey lever (which is the one connected to the braided pipe) is in the off position, then there is no water coming out of the hot tap.

I will get photos and detailed notes in the morning and try and post on my phone.
