This machine is likely loose in the floor. I've seen and fixed it too many times to count, often times removing and re-installing the machine.. Sometimes I have found cracked or broken steel mounting bases. If a service tech stuffed foam inside or around one of my machines to stop a vibration, I'd send him packing and find someone else. Unfortunately, there are many out there who don't understand the principle of vibration.I saw a loose Wascomat 50 pounder one time and told the owner what to do to fix it. The machine needed to be removed and re-mounted, but the owner didn't want to spend the $ to pay me to do it. He hired another guy who came numerous times, sticking wedges and pads everywhere, to no avail. When the machine frame got broken from the vibration, he hired that same guy to come in and weld up the frame, but still didn't re-mount it, and it shook completely apart.After the machine owner ended up buying a new washer, he asked me if I wanted the old Wasco for parts. The company he bought the new machine from was going to charge him to haul it away.Go Figure.
