Recently my diverter valve had to be replaced on my Worcester 9.24 combi. The heating was ok but the H/W began to come through slower until it didn't come through at all. After the valve was fitted, I could have the bath tap on full flow with a plentiful supply of H/W coming through.
The problem is beginning to come back with quite a delay until the heated water arrives, then surges of cold water flowing through.
Anyone got any idea's....is it the D/V up the shoot again or can something else cause this type of problem!!!!
