BEKO DE2431FW dishwasher fix needed????????? Please?

Hello,
I hope you can help. I started the dishwasher and went to bed, when i got up in the morning the dishwasher seemed to be stuck mid cycle and was still trying to finish it's cycle(All Night). When i opened the door it seemed to have a lot of soap suds, don't know why! It didn't seem to be draining so i eventually reset it and the water drained but now everytime i switch it on it seems to start fine when it is filling up and then just as it begins its wash it drains all the water away and the machine just seems to keep try to wash with no water and makes a whiring noise(like it want to wash but its missing the water)
I really hope you can help and this come from someone who didn't really think she would use it and was a waste of money, boy was i wrong and i never even realised it until it packed up!
Thanks for taking the time to read this, i hope you can help!
