Whirlpool Dishwasher Not Cleaning Dishes: 6 Fixes

Common Symptoms

• Dishes, glasses, or silverware come out with food residue
• White film or gritty residue on dishes after washing
• Glasses appear cloudy after the cycle
• Water pooling at the bottom of the tub
• Detergent pod not fully dissolving

Most Likely Causes

1. 1

   Clogged Dishwasher Filter (Most Common on Modern Whirlpools)

   Whirlpool dishwashers made after 2010 use a manual-clean filter under the lower spray arm. When it's clogged with food particles and grease, water can't circulate properly. Clean it monthly for best results.

2. 2

   Blocked or Cracked Spray Arms

   The upper and lower spray arms have small holes that jet water onto the dishes. These holes clog with mineral deposits and food debris. A cracked arm will lose water pressure and miss large areas of the rack.

3. 3

   Water Temperature Too Low

   Dishwashers need incoming water at 120°F (49°C) to dissolve detergent properly and remove grease. If your water heater is set too low, or the heating element in the dishwasher is failing, dishes won't get clean.

4. 4

   Wrong or Too Little Detergent

   Using dish soap (hand soap) instead of dishwasher detergent will create excess suds and poor cleaning. Using too little detergent, or storing pods in a damp dispenser, also reduces cleaning performance.

Quick DIY Checks

1. 1Remove the lower rack. Twist out the filter assembly (usually a quarter-turn counterclockwise) and lift out the mesh screen beneath it. Rinse both under warm water, scrubbing with a soft brush to remove grease and food. Reinstall firmly.
2. 2Remove the lower and upper spray arms (usually unscrew counterclockwise or pull off). Use a toothpick to clear each spray hole. Hold each arm up to the light — all holes should be open. Rinse and reattach.
3. 3Check hot water temperature at the kitchen sink: run the hot tap for 30 seconds, then hold a thermometer under the stream. It should read 120°F. If not, adjust your water heater thermostat.
