Ideal Mini c32 Hot water problem

[ROLOPOLO]

Hi all,This is my first post .

My Daughter has a problem with her hot water, working occasionally. The boiler is an Ideal mini C32, when the water is turned on the Water flow led is lit, on the PCB 1 the two green led's alternate as per normal. Then the middle (red) led is lit and the left hand green led flashes. On the diagnostics this states that there is no water flow detected. As the Red led on the flow switch is lit I think it is detecting a flow of water. I have changed the PCB 1 but no change.

Any help would be appreciated.
Regards Rolopolo

For less than the cost of that new pCB I would have diagnosed the fault on site if it was in our local area.

The water flow the fault code relates to is the system water and not the DHW flow.

Thanks Tony,
I am going to get an engineer in but just wanted to know what parts to order before he comes ( 2 callout charges).
