I fixed my washer without taking it apart! I would have had to take apart entire washer to fix clogged pump. But instead I
1) used EXTREMELY hot water and let it drain a few times, putting the hose on the ground, turn your water heater to maximum for this, you might see clumps of what is clogged coming out.
2) sucked and blew air into the hose and back out to help unclog the water pump
3) started to shake and slide the washer back and forth as it was on it's drain cycle, with the house on the ground.
4) after doing this for about an hour, THE WATER PUMP STARTED WORKING and a HUGE clump of my rugs came out of the machine.
