Common Reasons for Poor Dishwasher Performance

Clogged Spray Arms

The spray arms on your dishwasher are made up of holes which spray water evenly over the dishes. Food particles and hard water deposits can plug the holes on the spray arms.

Repair instruction: Remove and rinse spray arms under running water, and use a toothpick or small brush to scrub away any blockages.

Dirty Filter

If your filter becomes dirty or clogged, the water supply to the dishwasher may be restricted and dirty water can flow through the dishwasher and onto your dishes.

FIX: Filter Locate the filter at the bottom of your dishwasher. Remove it from the dishwasher and rinse it under running hot water until clean. If a large amount of debris is still attached to the filter, you may also need to use a soft-bristled brush to clean out debris.

Overloading

DO NOT OVERLOAD THE DISHWASHER WITH TOO MANY PLATES.

Fix: Make sure you leave enough space between your plates so that the water can reach the entire surface. Check your dishwasher manual for proper loading techniques.

Incorrect Detergent Use

Using too little detergent will not be enough to clean the dishes. On the other hand, using too much detergent can leave behind residues on the dishes.

FIX: Measure detergent as directed for the size and soil level of your load.

Hard Water Issues

Water with a high mineral content is called hard water. White mineral deposits known as scale are left on the surface of your dishes and appear to still be dirty.

Fix: Some dishwasher rinse aids have been formulated for hard water areas. You may need to try a different rinse aid or install a water softener on your main water line.

Additional Tips

HOT WATER SUPPLY Check the hot water temperature by inserting a cup and testing for 120° F or higher before attempting to start machine.

Maintenance: Every month run an empty cycle with vinegar to eliminate grease and limescale deposits.
