6 Causes of a Samsung Dishwasher Not Cleaning Dishes

When the dishwasher is done but dishes are still dirty, hand washing each item won’t solve the problem. Why is a Samsung dishwasher not cleaning sufficiently? Improper usage like selecting the wrong wash cycle or incorrect loading techniques can affect performance. Troubleshoot how to fix a dishwasher not cleaning properly with our list of common causes and solutions.

Samsung Dishwasher Not Cleaning Properly? This Could Be Why

When an appliance doesn’t work as it should, repair or replacement is a likely concern. But a simple fix or minor adjustment can usually fix a Samsung dishwasher not cleaning dishes. These 6 common causes point to the most likely problem and how to fix it.

1) Water Supply Problem

Before determining a malfunction, Samsung dishwasher troubleshooting should first consider a water supply issue. Problems with water temperature, pressure or supply can all result in dishes that are still dirty.

Here’s how to assess water supply problems:

  • Low water temperature: Make sure your home’s water heater is set to the recommended 120℉ to ensure that water is hot enough for optimal performance. Running the hot water in your kitchen sink for 30-60 seconds before starting the dishwasher can also ensure hot water is readily available.
  • Insufficient water pressure: If the pressure in your kitchen sink also appears diminished, your home’s water pressure may need a professional evaluation.
  • Reduced water supply: A lack of water in the dishwasher may be due to a faulty water inlet valve. This valve opens and closes to allow water to enter the dishwasher as needed. A faulty inlet valve requires replacement.

2) Not Using Dishwasher Properly

Why is my Samsung dishwasher not cleaning bottom rack dishes? It could be due to improper loading and setting selections. Common dishwasher loading tips suggest alternating forks and spoons next to each other to prevent nesting. Avoid overloading with too many dishes so water and detergent can reach each item.

We also recommend checking your wash settings to make sure you’ve selected the most appropriate one for your wash load. Heavily soiled loads may require a “Heavy” wash cycle, while certain food stains may benefit from hotter water temperatures to be thoroughly cleaned.

3) Dishes Have White Spots

White spots on glassware are most often caused by hard water or etching and not a dishwasher malfunction. Reduce the effects of hard water by purchasing a water softening system and consistently using rinse aid with each wash load. While etching can’t be reversed, it can be prevented by not pre-rinsing dishes and reducing water temperature and detergent amounts.

4) Clean Dishes Have Stuck On Food

If you find your Samsung dishwasher leaving food particles on dishes, skip any pre-rinsing before loading. While large food particles and bones should always be removed, most detergents work best when dishes have a little grease and grime.

If dishes are still dirty after a wash cycle, you may also need to check the dishwasher filter. If it’s full of food particles and debris, water won’t drain properly, leaving food and stains stuck on dishes. Remove the filter and rinse it under running water to clean it of any blockages.

5) Spray Arm Malfunction

A Samsung dishwasher not spraying water is often due to clogged spray armholes. During a wash cycle, water sprays from the holes to clean and rinse dishes. However, if the holes are blocked, water won’t be able to flow and dishes will remain dirty.

Important dishwasher cleaning steps include detaching the spray arms and gently scrubbing them with a soft brush and warm soap and water. Use a toothpick to dislodge any blockages in the spray armholes. If the spray arms are damaged and water can’t flow properly, they will need to be replaced.

6) Dishwasher Detergent Issue

Detergent issues are one of the most common reasons for a Samsung dishwasher not cleaning dishes sufficiently.

These are some common detergent problems that affect dishwasher performance:

  • Too much detergent: Can leave behind spotting and residue.
  • Too little detergent: Won’t be able to remove all food stains.
  • Wrong type: Consult your user manual to determine if a particular detergent is recommended. If not, choose a high-quality brand and never substitute detergent for dish soap or other cleaners. If you have hard water, consider using a detergent formulated for that purpose.
  • Dispenser malfunctions: Check the dispenser to make sure it’s opening and releasing detergent properly. If the dispenser has malfunctioned, it requires replacement.
