Loose ball in the hose from the drum is normal. If the pump is running and the impellor is not loose and if no water comes out on CKs test below, then there is a blockage in the pipe from the pump. If your model has an anti syphon box inside the machine top right then it will probably be blocked with old soap like a grey clay, or a coin or button. Cheers
