Sometimes the dishwasher never cleans dishes properly and it may be due to lack of hot water. In general, hot water is much better for cleaning dishes than cold water because it breaks down food particles and strains. The hot water actual temperature is 120°F and if it is less than this temperature, you must make some adjustments:
- First make sure that hot and cold water lines under the sink are in correct position.

- Avoid overlapping of the dishes so that every dish gets access to water properly.
- You can also check user manual for rack by rack loading tips.
- Place the items in a way that taller items and pots don’t block the wash arms.
Whirlpool Dishwasher Not Cleaning: Detergent Amount Or Quality
Too much soap and detergent can cause residual build up on the dishes. Some rinse aids can also result in streaky and cloudy dishes. It is also one of the most common reasons for your whirlpool dishwasher not cleaning.

- Wait for 15 minutes and then pause the cycle to check the drawer is working properly.

Rinse aid is helpful in minimizing the buildup of hard water. It also provides optimal washing and drying performance.
