Why Is My Dishwasher Water Brown? Here’s The Shocking Truth!

A brown hue in your dishwasher water can be an unsettling sight. This unexpected discoloration can raise concerns about the cleanliness of your dishes and the overall functionality of your appliance. Understanding the causes behind this issue is essential for finding an effective solution.

Causes of Brown Dishwasher Water

1. Rust:

One of the most common culprits behind brown dishwasher water is rust. This can occur when the dishwasher’s interior components, such as the heating element or spray arms, become corroded by water or moisture. Rust particles can then be released into the water, resulting in a brownish discoloration.

2. Food Particles:

Food particles that are not adequately rinsed away during the wash cycle can accumulate and cause the water to turn brown. These particles can include coffee grounds, tea leaves, or sauces.

3. Iron in the Water Supply:

If your water supply contains high levels of iron, it can lead to brown dishwasher water. Iron particles can oxidize and create a rust-like substance that discolors the water.

4. Detergent Residue:

Using the wrong type or excessive amounts of detergent can leave behind a residue that can turn the water brown. Some detergents contain minerals or dyes that can contribute to discoloration.

5. Mineral Buildup:

Hard water contains minerals such as calcium and magnesium. Over time, these minerals can accumulate and form a scale on the dishwasher’s components. When this scale breaks down, it can release brown particles into the water.

6. Drainage Problems:

If the dishwasher’s drain hose is clogged or kinked, it can prevent the water from draining properly. This can lead to a buildup of dirty water and food particles, which can turn the water brown.

7. Faulty Water Inlet Valve:

A faulty water inlet valve can allow water from the household plumbing system to mix with the dishwasher’s supply of water. If this happens, the water can become brown if the plumbing system contains rust or other contaminants.

Troubleshooting Brown Dishwasher Water

1. Inspect for Rust:

Check the dishwasher’s interior for any visible signs of rust. If you notice any rust spots, you will need to remove them to prevent further discoloration.

2. Clean the Dishwasher:

Run an empty dishwasher cycle with a dishwasher cleaner to remove any food particles or detergent residue. You can also use a mixture of vinegar and baking soda to clean the dishwasher.

3. Test the Water:

Fill a glass with water from the dishwasher and let it sit for a few minutes. If the water turns brown, it indicates that the problem is with your water supply. Contact your local water supplier to inquire about iron levels.

4. Check the Drainage Hose:

Inspect the dishwasher’s drainage hose for any blockages or kinks. If you find any, clear them to ensure proper drainage.

5. Replace the Water Inlet Valve:

If you suspect that the water inlet valve is faulty, you will need to replace it. This is a more complex repair that should be performed by a qualified technician.

Prevention Tips

• Use a dishwasher-safe detergent specifically designed for your appliance.
• Rinse dishes thoroughly before loading them into the dishwasher.
• Clean the dishwasher regularly with a dishwasher cleaner or a mixture of vinegar and baking soda.
• If your water supply contains high levels of iron, consider installing a water softener.
• Check the drainage hose periodically and clear any blockages or kinks.
