zanussi jetsystem 1200 fjs 1225w?

there is a blue wiring loom with 5 wires that goes from the main pcb to the display pcb.normally bad connection on the display pcb end.clean and crimp connections and hopefully it will get rid of the E90 fault code.this also could be a faulty display pcb or main pcb if the above doesn't work
