My Bendix biw105w wont drain all of the water??

After every wash i have to empty the water out of the washer manually, throught the tube at the bottom right hand side of the washer. If i leave it for longer than an hour or so it begins to smell... everything else works on the washer but i cant understand why it isnt draining properly??
Also i have to run the spin cyucle after every wash becasue there is too much water in the drum..
Please help!! I cant afford a new washer!! xx
