The hot water for the shower doesn't always come on but is ok for the other hot water taps - basin and kitchen sink. The shower has the lowest flow rate.
I suspected the diverter valve diaphragm but there were no splits or tears. I replaced the diaphragm and everything else that came in the diverter service kit. The hot water seemed ok for a few days but has gone back to being intermittent.
The microswitch doesn't seem to operate the times the DHW doesn't come on despite re-adjustment.
The Central Heating radiator supply pipe also gets warm for a little way (heating not on) when the DHW runs for a little while.
Replacement of entire diverter required?
