E30 is a pressure system issue or a heater down to earth
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.The only other time E90 comes up is when people lay the machine on its side with the soap draw at the top.This allows water to run in to the electronics and knackers the machine in an expensive way.Please tell me you didn't lay machine on its side soap draw up?
