ADG 6552 7 flashes

[d-ray]

I have changed the presssure switch and the water valve is ok
but I still have 7 flashes I can only presume the board is faulty
or is there any thing else it can be

It may be the flow meter which is part of the metering tank on this model. It acts a bit like a motor tacho and sends pulses to the PCB as water passes through it.

F7 or 7 flashes is a “no fill” error of sorts so it could also be the PCB as well 🙁

Most likely cause is the flowmeter, try tightening the connections at the flow meter and at the module.
Before moving jobs I had a few of the newer machines giving error codes that had nothing whatsoever to do with the fault. For example one machine was flashing F7 and had a flooded base, another Flashing F4 turned out to be a duff NTC.
In the main the faults were mostly attributed to the NTC, flowmeter connections, pressure switch and corrupt software on the module (no heat was the usual one for the software).

It was the plug on the flow meter

Thanks again
