How can I fix my Ariston central heating boiler CLAS/ HE38?

Have replaced PCB in the boiler and "error code 302" has appeared it is communication error. Could it be one of the connectors wrongly fitted?

did you get this fixed we have the problem

Just wondering whether you got this resolved as I now have this error message. I had replaced the water flow switch and everything was working fine so reassembled boiler case but when switched on I got error 302. I suspect a cable connection has been stressed but not sure.
