If you remove the filter again and look inside the chamber were the filter goes at the back in there you will see the pump impeller X shape. Check theres nothing stuck in there jamming the impeller up and stopping it from turning. As the impeller should ping round in stages.
Check that first and see what you find and let me know.
Ok when you set it going on a spin cycle to drain the water out do you actually hear the pump running at the bottom?
Ok if the pump is running but not draining and the waste hose is clear as well then the blockage will be in te sump hose. This is the hose that goes from the tub to the pump.
You need to pull the washer out and lie it on its back.
From there you will see the black hose going from the tub to the pump.
Remove the hose from the drum end and clear out the debris from in there.
Once its all clear refit the hose and stand it up right and retry the washer and fingers crossed this will will sort the draining out from there.
As with the pump clear and running then it can only be a blocakge in the sump hose or waste hose on this washer.
Ha ha gives you a break from the football does it.
Fingers crossed this may be fine for you now.
