possible. best way to see if pump is working correctly is to remove it from machine,remove housing to gain access to impellor,secure a piece of tape to one blade and while running pump feel with finger iff tape is running in circle and not just agitating in one place.it sometimes sound like pump is running but with this you can feel pump turning full circle.hope it help!!please just be carefull off elect power!!!!!!
