LG front loading washer: recently moved to a new house and laundry room is on the 2nd floor. Re-installed the shipping bolts in the back of the washer that secures the drum prior to moving the washer. But ever since we started using the washer at our new home, the machine shakes the entire house quite viloently. Sounds like a helipcoter is landing on the roof! HELP!

Make sure machine is level and all four leveling legs are solidly touching floor at the same time. Make sure leveling leg locking nuts are screwed up to lock legs in place. Check floor for firmness. (try bouncing up and down in front of washer to see if the floor has excessive give.) You may need to re-inforce floor. Wash larger loads. On bulky items, use a lower spin speed. You can re-spin at a higher speed after cycle is complete if you want them spun out better. (some models have a pump and spin only setting, on others, just turn on the power and then only touch the spin speed button to select a 14 minute pump and spin only cycle, then touch the start button.) The only other thing is that the new LG washers use a balance ring now, which makes the machine perform much smoother. (I know because I gave my old LG to my son and replaced it with the newer model, which now runs much quieter, in the exact same location as the old one.)
