My zanussi zjd1219 washer/dryer developed E90 fault?

have you disconnected the blue loom from the pcb in the fascia and cleaned the edge connector and slightly tighten the the tabs in the connector to get a good connection?
if you are happy with the above it now gets expensive and hit and miss.could be display pcb faulty,main pcb fault or if you are unlucky BOTH!
