How to Check the Drain Line on Your Whirlpool Dishwasher
If the drain line is not installed properly, the dishwasher will not drain, and residual water will remain in the bottom of the tub, and can cause leaks.
Look under your sink and make sure that:
- The drain hose comes through at the bottom of the cabinet.
- If you don't have an air gap, make sure the hose is looped so that it touches the underside of the counter (picture below shows arrow pointing at air gap)
- Check that drain hose clamp is correctly positioned.
