AEG lavamat 72636 shows E90 and its not working. ?

E90 is a communication error between the pcb and the display user interface pcb.5 wire blue loom gets a bad connection where it plugs on to the user interface pcb.remove wiring and clean display pcb edge connections.this may require the control panel being totally removed

This doesn't explain water leak and it does sound terminal/expensive.pcb or display issue?
