We have a Worcester Combi Boiler heatslave 15/19 which suddenly won't go off inspite of having switched off the control in the house AND the select switch/button on the boiler itself. All the heating in the house is constantly on !! This is our second winter in a fairly modern house and it has worked fine up until now.
