Hotpoint WMA62 Problem?

after looking at a similar post on here I thought the problem with my WMA62 was down to blockage in the waste system somewhere, after removing, cleaning and refitting the filter and drainage hoses etc (and cleaning out a fair bit of crud) its still the same, if you try a spin cycle it gives a short attempt at a fast spin, idles for a bit tries to spin again and then stops, if you try a rinse and spin it fills then tries to spin, idles and stops and does the same on a wash programme. Help!?!

thanks in advance
