You expect clean, sparkling dishes while unloading your dishwasher. Lately, you may have noticed dishes with food particles stuck on them. So, you wash those plates and bowls to remove the residue from last night’s dinner.
Why is your dishwasher not cleaning dishes properly even though it’s brand new? Well, various factors can contribute to a dishwasher not working. For example, it can be a dirty or clogged filter, a broken soap dispenser, or issues with the water supply.
On top of that, a dishwasher that doesn’t clean properly can increase your water bills. Moreover, it’s inconvenient that you have to do your dishes, pans, and silverware by hand. Let’s check out how to fix a dishwasher not cleaning, but with the reasons first.
Why is My Dishwasher Not Cleaning Properly?
Here are some common reasons why your dishwasher might not be cleaning dishes:
1. Clogged or Dirty Dishwasher Filter
Your dishwasher filter traps food and debris, which can cause clogs. For dishes to be clean, an unclogged filter is what your dishwasher needs.
2. Dirty Interior
Over time, grease and small bits from food and soap scum can build up inside the dishwasher. While cleaning dishes, the appliance is just transferring that debris to your dishes. This is why your dishwasher is not cleaning dishes effectively.
3. Water Temperature Fluctuations
For proper cleaning of dishes, the water must reach at least 120°F inside the dishwasher. If your dishwasher doesn’t set the water temperature, your dishes might come out dirty. Also, the right amount of water is mandatory for your dishes to be squeaky clean.
4. Damaged Soap Dispenser
A broken soap dispenser could be why your dishwasher isn’t working properly. Indeed, a broken soap dispenser won’t release the right amount of soap while washing the dishes. For instance, a jammed spring in the dispenser door is a common problem.
5. Clogged Spray Arm
Your dishwasher consists of spinning spray arms shooting water through tiny holes. These are called jets, and they clean your dishes. The water pressure can be compromised if these jets are blocked in some way.
6. Low-Quality Detergent
Why is my dishwasher not cleaning properly? Well, the answer might lie in the detergent you use for cleaning your dishes and bowls. Using low-quality detergent will leave your dishes spotty. Using too much detergent can leave water spots on your silverware, pots, and pans.
7. Failure to Load Dishes Correctly
Your dishwasher requires proper loading of dishes. Otherwise, water jets won’t reach them as they should and clean those dishes. So, your dishes will come out soiled and with detergent residue on them. Don’t be too surprised if you notice scratch marks on your dishes after unloading.
8. Choosing the Wrong Wash Cycle
Choosing the wrong cycle can make dish cleaning ineffective. Each dishwasher cycle targets specific loads, such as delicate, normal, or heavy-duty. So, your dishes won’t be as clean as expected if you select the wrong cycle.
9. Broken Inlet Valve
Do you hear a strange noise during the wash cycle? Then, chances are that the inlet valve of your dishwasher is broken or damaged. Reportedly, it can cause improper cleaning.
10. Hard Water
If you notice water spots or chalky residue on your dishes after cleaning, then you may blame it on hard water. Hard water is filled with minerals such as calcium and magnesium. Apart from your dishes, hard water can leave buildup inside your dishwasher.
How to Fix a Dishwasher That Is Not Cleaning Dishes?
By now, you are aware of the reasons why your dishwasher is not cleaning dishes properly. It’s hard to find the exact reason without help from dishwasher repair services. You can still try these solutions for your troublesome dishwasher:
1. Clean the Dishwasher Filter
Since a clogged filter can give you dirty dishes, see if cleaning the filter solves your problem. Refer to your dishwasher’s user manual to learn how to dislodge the filter and clean it. Typically, you need to remove the filter from the bottom of the dishwasher.
Then, soak the filter in warm, soapy water. In case you notice stubborn debris, you can scrub the filter with a soft-bristled brush.
2. Clean the Interior
Why is my dishwasher not cleaning properly? If the filter is not the culprit, then take a look at your dishwasher’s interior. To clean your dishwasher’s interior, follow the guidelines below:
- Take 3 cups of white vinegar and pour them into the bottom of your appliance.
- Then, run a full wash cycle.
White vinegar helps remove debris from the holes in the spray arm. Also, it dissolves mineral buildup from your dishwasher’s interior. Additionally, it will sweep away the grease from the walls. After a wash cycle, your dishes will start smelling even better as well.
3. Adjust the Water Temperature
Another reason your dishwasher might not clean dishes well is that it can’t reach the right water temperature. Inspect whether hot water flows into the appliance from the very beginning of the wash cycle.
See if your dishwasher has a knob to heat the water. If it doesn’t, check if it raises the temperature automatically.
4. Fix the Soap Dispenser
How to fix a dishwasher not cleaning because of a jammed soap dispenser? Well, you can fix the jammed dispenser door spring. Simply make a solution of warm water and vinegar. Then, locate the soap dispenser door using the user manual.
Clean the soap dispenser and its door spring with the solution. This removes grease and gunk. Now, run a full wash cycle to see if the dishes come out clean this time. If the soap dispenser is broken, contact dishwasher repair services. Only a compatible replacement can save your machine and dishes.
5. Clean the Spray Arm
If you think the spray arm is why your dishwasher isn’t cleaning well, here’s what to do. Check out how you can clean the spray arm so the water pressure can be retained.
- Start by checking your dishwasher’s user manual to learn how you can detach the spray arm. Typically, you need to remove a few screws to bring out the spray arm.
- Once the spray arm comes off, you can scrub it with dish soap and a soft brush.
- Also, unclog its holes using a toothpick.
- Rinse the spray arm with warm water.
Before you install the spray arm back in its place, spin it to ensure that it rotates without any problem. If you still experience flaws, contact dishwasher repair services.
6. Use the Right Detergent in the Required Amount
Are you using the right dishwashing detergent for your machine? Make sure you use only automatic detergent. Otherwise, you might end up with improper washing and overflowing suds.
Make sure you’re using the right detergent and the right amount. Using too much powder won’t be a great idea. If left unused, detergent powder can turn into clumps. Later, your dishwasher will face difficulty dissolving it. Also, store the detergent in a cool and dry place.
7. Load Dishes Properly
Loading your dishwasher is an important step that most users overlook. Improper loading can give you dirty dishes back. Always place dishes with their soiled side down and inward toward the spray arms. Additionally, maintain proper spacing between dishes.
Verify that you won’t end up overstocking. Also, you should not block the spray arm. Thus, water will reach all surfaces and you will get effective washing, rinsing, and drying. Furthermore, load glass items and aluminum utensils, maintaining a safe distance. Otherwise, your dishes can be stained.
8. Carefully Select the Wash Cycle and Settings
Your dishwasher comes with many wash cycles and settings. Choosing the wrong cycle or settings can cause your dishwasher to malfunction. For example, you can switch to the Normal cycle when your dishes are with average soil. If you need a swift wash, then you can choose the Quick Wash Cycle.
However, for too many soiled dishes and bowls, you need to select the Heavy cycle. Hence, you need to be selective about the wash cycle and its corresponding settings. Otherwise, you may not get the desired results.
9. Install a Water Softener
Hard water buildup can be another headache for your dishwasher’s efficiency. However, it has an easy solution. Install a water softener on the incoming water line of the dishwasher. Thus, you can control the damage from mineral deposits.
10. Replace the Inlet Valve
If your dishwasher isn’t cleaning dishes well, the inlet valve may be damaged. However, there’s not much you can do if the inlet valve is broken. Rather, you should get in touch with dishwasher repair services.
Only seasoned technicians can inspect the inlet valve and replace it if required.
