Hi, I have 2 lights flashing on my dishwasher, hotpoint fdw20, the prewash and rinse. Did have the prewash only yesterday but after advise on here turned machine off and drained water from base by tipping the machine backwards. Put it on to wash last night and all appeared well untill I returned to the machine this morning and now 2 lights flashing, any ideas? thanks
