my dishwasher used to display the 'not draining message' but now shows the e9 pressure switch code. have rung smeg and clarified this. appears to wash fine till the last 20 minuets when it has a hissy and chucks all the water out. sometimes it works fine. any ideas on how to mend it? also the swaying roter arm on the bottom gets stuck, are there parts missing? please help me!
