One of my tenants called with a dishwasher issue. Went over there today and the dishwasher is working but when it drains the water after a cycle completes when most of the water is out the thing sounds like a buzz saw is going off.

i took off the bottom panel and see the drain pump and can feel it vibrate as it is pumping the water out. Do I need to just get a new drain pump or is there something else I can check before going throught that expense?

Thanks in advance for any help!
