Hi can anyone help please? My Worcester Greenstar HE boiler has just stopped heating the radiators and the water. It's been on fine this morning. My kids had their showers which is pressure driven through the taps as opposed to electric and when I went in for mine and ever since, the water has run cold. The boiler display was showing 99 which is not normal, it's usually 54 or thereabouts. There are no error codes showing. The wireless controller is working fine as it is switching the little box to the side of the boiler on and off ok. The boiler initiates fine but switches off about three seconds after initialising. Any help would be much appreciated. Im at a bit of a loss. I'm poorly and have no one else to ask so a little sorry for myself today 
Thank you.
Thank you.
