dishwasher not filling?

I have the Beko DWD4311W model , its stopped working recently, i have pulled out the dishwasher checked the water inflow and also checked to see if the unit drains when its turned on, the water drains no problem, but the program stalls on the wash program after the inital drain. I have tipped the unit backwards also to see if this freed up anything , but no happens now, any furhter advice would be
