If the problem with your Performa washer is that it fills to the selected level, agitates properly, but is not draining at all or is only draining partially.
The problem could be an obstruction somewhere between the tub and the drain hose.
You will need to bail out the water from the tub, and make sure that there is no water left on the tub to pump hose and the pump to drain hose.
Make sure to get a couple of towels to clean any water spills on the floor when disconnecting the hoses.
