I can NO longer put my hot water on without having the heating on at the same time,the timer and the 1hr boost seems to be working ok but only if both heating and water on at same time.Do i need a new heating control ?? or can it be repaired ??

Just had the same problem. Sometimes the C/H will switch on and then immediately go off again even with H/WE on. Somedays it all works fine. Just doesn't seem to be any pattern to it!
