The water does not get pumped out of the machine

The filter is to be found at the bottom front left of washer behind a removeable plastic trim, if you can see a screw in the filter cover, undo this, and turn filter anticlockwise to remove.
If no filter at front, then remove rear panel of washer, and remove large black hose fastened to drum, check for blockage here, and check the pump at the same time.
