Noisey dishwasher

Noise may be coming from faulty parts, but it also may be caused by improperly loaded dishes; check your owner's manual for proper loading methods. Next, when the dishwasher is completely cool, look in the openings around the pump at the bottom of the dishwasher's interior; be sure no implements or hard debris such as bones, fruit pits, or silverware are stuck in them.

Be sure your dishwasher is sitting level. Adjust the feet beneath the unit by screwing them up or down. If there are lock nuts on the feet, make sure they are tight.

A thumping or chattering sound during the filling cycle usually indicates that the inlet valve needs to be replaced. Unless you're handy with this sort of repair, this is a job for a repairperson.
