Hello. I think this is the model..it looks

Well Bridie no there is no lint filter inside your washer the only possible explanation, is either old lint and particles are coming from previous washes. or you have just washed something recently that may have come apart such as a pillow, a mat with a rubber backing, or even a blanket with any sort of fiber material in it. It is more than likely that much of the lint that goes through your machine is unseen and can cause pump issues. hope this helps.

Thanks
