HELP! - Worcester Bosh 24CDi - no pressure & cannot refill manually

[julesij]

Ok so I am not very technically minded - sorry so here goes. . .

My boiler has been losing pressure for a while - lost the lost 2 nights ago to 0 but seemed to refill itself. However, today 0 agin & no hot water - steam comming out of the top of it when you put the H/W tap on? I have tried to follow the instructions & turn the filling key "anticlockwise" but can do this forever with no change - it just goes round & round. Turn the grey key & water comes out. turn it on/off & nothing happens - just stays on 0.

Any idea of what is wrong with it? Does this need a plumber / new boiler as £ very tight (have home emergency but no service history - or if we had not sure where it is) in the throws of a DV here - so trying to sort it myself

Thank you JJx

Never run your boiler dry !!!

You may need a new pressure relief valve fitted if pressure keeps dropping.

if its blowing steam out of the aouto air vent, then its possible the pump is knackered.

It has lit when it was empty. Worcesters don't have a low pressure switch

Thank you all

I will get a plumber to have a look at it in the week as it just ran dry by itself overnight, but it just helps me in the meantime - decorating so need hot water.

Thanks JJ
