Following me bleeding a rad, our boiler displayed F. 22 and the heating cut out. It is now displaying F. 1. As our landlady is Polish, our instructions are also in Polish!

Can anyone tell us what the problem is and how to fix it?

BOILER STAT NOT CONTROLLING WATER TEMPERATURE VALIANT BOILER VCW 25/1 T3 W

GEORGE CHAPMAN, April 2008

when you bled your radiators you lowered the pressure on your system. It needs to be 1 to 1.5 bar. look under the boiler for the filling loop, a silver flexible pipe with one or two black knobs on it. open it or them and you will hear the water filling the system. make sure to close the knobs at the correct pressure. If no filling loop, there will be a small plastic knob on the underside of the boiler which will do the same job

you will have to re pressurise your heating system on the underside of your boiler towards the front right hand side there should be a small golden key sticking out from under your boiler you need to turn this a quarter of a turn and watch the pressure gauge on the front of your boiler gradually rise to one - one and a half bar then turn it back off next you will need to press the reset button which is next to the display and is a flame like symbol with a line through it if the key is missing you will have to fill it manually , where the key should be there is two straight headed screw driver slots you need to turn the one that is isnt running side horizontally quarter of a turn with a small screw driver
