Slurping noise

Slurping noise heard at the beginning of a cycle?

Cause and Symptoms

Residual water is drained at the beginning of a cycle. Heated and sterilized water remains inside the tub after every wash is completed to prevent food odor and contamination backwashing from the drain hose.

Relatively loud humming or slurping noise may be heard once the drain pump idles due to no residual water left inside the tub.

Can I perform a drain only cycle? The dishwasher does not have a drain function; however, the dishwasher will drain on its own for the first 45 seconds of a new cycle. To drain standing water, select a wash cycle and let it run for only 45 seconds. Then, turn the unit off and let it reset. Repeat as necessary.

This is not considered a defect and product is safe to use.
