When I switch the boiler the water heats up ok and the heating starts as

well but after some time there's a hissing sound and steam comes out

from the top of the boiler.

I checked the switch and thats working fine.

So please help as we have no heating and no water

thanks

Pumas are known for pcb and diverter being feeble, both are costly. Temperamental buggers anyway. The boiler warms itself up before letting the heat out to rads. This is often the bit where things go wrong.
