Hi, welcome to Just Answer. My name is XXXXX XXXXX X look forward to helping you! The noise islikely coming from the drain pump. Does it sound off during the cycle, too? Is the sound coming from the base of the dishwahser?
Hi Kelly, The noise also occurs when the water is being pumped in, so it sounds like it would be the pump. It comes from the base of the dishwasher. Is it a difficult job to replace the pump? Is it worth it? The dishwasher is 23 yrs old.
