E90 or E91 is a fault code on this model ????
E90/E91 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.Take top off and you will see blue loom going from main pcb to the user interface.clean pcb edge connections and tighten loom connections
