Hi, I've been having similar problems but with 3 lights flashing. I found this: http://www.ukwhitegoods.co.uk/help/fix-it-yourself/fault-codes/dishwasher-fault-codes/3118-haier-produced-6-led-dishwasher-models.html
Haier manufactured the adp8352 for mfi/diplomat. As far as i can gather it is a useless machine with rubbish service/user manuals. Hope this helps!
