Combi boiler stops supply hot water after i swtiched off the main stopcock

When I changed the water tap washer today, I switched off the main water stopcock. Then the washing machine was on and might used hot waster from the boiler.

Now when I turn the hot waster tap on, the boiler gas fire lights up for a few seconds, then off. As a result, there is not hot water.

Can any expert advise me how to fix the problem? Many thanks.

Has the water stopped running altogether from the tap? or is it running cold as a result of the boiler not firing up? If running cold and not firing the boiler then its an internal problem and you will require an engineer to attend.
