I have an Ariston SX20 combi boiler with a few problems. Central heating temperature will not go above 50C on the boiler guage. Tap has to be run very slowly to get any hot water. The water pressure drops right off, usually overnight, so no autostart in the morning.
Diverter valve seems to be working because it moves into position and pressures the microswitches when hot water is demanded.
Can you help?
