I have an Ideal ff350 boiler, EP2002 controller and a Megaflow system.
I noticed that I had a noise coming from the Megaflow last night. It sounded like it was still heating water or possibly a pump running. Sounded louder with ear to tank. Programmer was on timed but both CH & HW lights out as during off period. Boiler was still fired though!. Tried turning HW to off but it made no difference. Only way I could stop noise was to throw my "boiler" isolator switch which removes power to the programmer and boiler.
On reflection though must be my programmer, probably fused contacts.
Went to check it out again tonight, but it seemed to be working ok. Loudish click from programmer when first turned on. Left running to see what happened. this time same noise after timer had gone off for night. The boiler was not fired when i checked. Noise still coming from Megaflow.
This has made me wonder if my first diagnosis is correct or could it be something on the Megaflow side?
