Das Dot on status of Ideal Acos HE15 boiler

[chris.newty1969@gmai]

I have a Ideal Acos HE15 boiler and all of a sudden I have no hot water or central heating. Ideal status has a dash dot symbol. Ideal rep has said that this is a communication error with the PCB. Does this mean I require a new PCB or is this an easy fix?

Not something I’ve heard of, but I’ve only worked on a few Ideal Isar/Icos. Any work carried out recently?

No work carried out recently.
What's weird is my boiler has just fired up at midday for a short time.
But still "dash dot" on boiler status.

Does sound like the pcb or a loose connection (hence asking about work carried out). Replacing the pcb isn’t a diy job though. There’s a white plug in connector where it connects to the pcb - check this is pushed fully home.

I know it's not a DIY job. I asked an engineer to come and look but was new to the job and needed to ask his trainer for more advice. That's why I have asked on here. Just to get a bit more understanding of what is needed. Thanks for the advice. I will check this connection first.
