If your washer makes a loud noise and/or vibrates when it spins or when it stops spinning, first check if the load is unbalanced and rearrange the contents to balance the load. (See a few more easy fixes in this article).
If the problem persists, possible causes for a top-load washer are a loose spanner nut on the spin basket, a worn drive block, a bad clutch, a broken shifter assembly, or a damaged spin basket.
If you hear a loud buzzing during the agitation or spin cycle for a direct-drive top-load washer (a washer whose lid doesn't lock during the wash cycle), but the washer basket doesn't move, it's likely the motor coupler is broken.
If you have a front load washer, causes of unusual noises include a damaged spin basket, a broken shock absorber and a failed outer tub bearing.
If you hear a loud rattling as the drain pump runs in a front-load washer, check for coins or other debris in the drain pump filter. Our video show how to clean out the filter if your washer doesn't have a drain pump access door at the bottom of the front panel.
To avoid noise problems, level the washer. If your washer has a drain pump filter, clean out the filter periodically.
