BEKO DISHWASHER?

I have a slimline beko dishwasher, it worked fab for a year then we moved & it went into storage for 2 1/2 years. We've just plumbed it in at our new house & it's misbehaving. It sounds like it's starting it's cycle & it sounds like water is going into it but then nothing happens, it just seems to stop. When we open door, water has collected in the drainage bit at the bottom but we've tried tipping it back 45 - 80 degrees & no water comes out, we've tried tipping it forward too & nothing. Can anyone offer a suggestion?
