Hi group, my Mother has a thermostatic bar mixer shower valve fitted, the hot water is supplied by a worcester combi 24i. The shower works fine, then it goes cold, there is no pattern to it and it will become warm again on its own accord. Domestic hot water and the central heating appear to be working fine, this has been happening intermittently for about 3 weeks now. We live in a non HW area, are there any basic checks I can carry out before scopping the shower bar through me Mums bathroom window
Kindest regards, Otto
