Hi -
I've had this dishwasher for just over 2 years, recently has become extremely loud. In fact, if I set the delayed start - it will wake me up in the middle of the night. The sound is a constant humming while in the wash cycle. Is there anything I can do, or does this require a service call? Thanks in advance for any advice.

The new noise could be several things such as a bushing or bearing going bad or debris caught in the impeller. See if your strainer at the bottom of the sump area can be removed from the inside and check for debris. 2 years is a long time but I'd reread the warranty info to see if its out of warranty. Bushings and bearings usually last much longer than 2 years so I hoping you find debris.

Must spread some around, ball, but you are right on the money
