How can i fix my Hotpoint Aquarius+ FDW75 Dishwasher?

My Hotpoint Aquarius+ FDW75 dishwasher has recently started coming up with A10 or AID on the display and also makes a dry gurgling noise just after a cycle starts, it sounds like no water is getting in but when we cancel the cycle it does drain out some water. It doesn't clean dishes if we leave it going. I really need to get it going again, I miss my dishwasher!
