Pottern boiler not working?

Was having a shower this morning and water went cold. Got out and noticed when getting ready that the power had gone off. The switch had been tripped on the main fuse board so reset everything. Power back on but no power or hot water to boiler. Any tips / advice? I have a Potterton Performa 24 Echo HE boiler, about 11 years old.
