THAT was VERY helpful thank you Mike.
I'll try it on my GW709AU
[Your suggestion/info] It [pump] is on the bottom, under the drum. Get all the water you can out from the machine. Unplug from the wall. Tip the machine over about 45 degrees. Disconnect two wires from the motor. Put a bucket under pump motor. Pull outwards on the plastic catch lever (between the pump and the bottom of the drum) while you twist the motor/pump anti clockwise. After a 1/4 trun the whole thing lifts right out. Clear the obsticle(s) and put it back-in (the opposite way to how you took it out).
