Feed and expansion tank could have run dry. Ball valves can stick in the shut position causing this fault. If you have access to the loft or place where it is, move up and down a couple of times and should sort out the problem, hopefully.

Could be a faulty 2/3port valve..

are you getting cold water from hot taps or no water from hot taps?
