Hi,
I have an Alpha CD24C which wasn't providing hot water unless the central heating was turned on. I read loads of other threads and figured out the flow switch was working fine so I went ahead and changed the diaphragm. I also replaced the old white thermistor for a newer black one.
Immediately after the repair it worked perfectly with the orange light coming on as soon as hot water was demanded. However, two weeks later it stopped and reverted back to its old ways of needing the central heating turned on to get hot water. I reset the boiler and now, after turning in a hot tap, there is a 20-30 second delay before the orange light comes on and the boiler fires up.
Should there be this delay, or am I overlooking something?
Any help would be greatly appreciated.
