Dishwasher Is Not Cleaning Properly

Dishwasher Is Not Draining Properly And The Common Causes

Dishwashers are a godsend for many households, saving time and effort that would otherwise be spent manually washing dishes. However, when your dishwasher isn’t cleaning your dishes properly, it can be a source of frustration. In this comprehensive guide, we’ll explore the common reasons why your dishwasher might not be cleaning your dishes effectively and provide step-by-step instructions on how to resolve these issues.

1. Dirty Interior from Food Deposits

Over time, small bits of food, grease, and soap scum can build up inside your dishwasher, preventing it from doing its job effectively. If your dishwasher is not cleaning properly, the first step is to clean the interior of your machine.

Solution: Pour 3 cups of white vinegar into the bottom of your empty dishwasher and run a full wash cycle. The vinegar helps remove gunk from the holes in the spray arm, dissolves light mineral buildup, and cleans grease from the interior walls. This can be a simple solution if your dishwasher is not cleaning properly. Your dishes may even smell better too.

2. Poor Quality Detergent

Another potential cause of a dishwasher is not cleaning dishes properly is substandard detergent—or too much detergent.

Solution: Check your manual to ensure you’re using the right kind and amount of detergent. You can also use a rinse aid, which helps your dishes dry faster, preventing spots from forming. This can significantly improve the performance if your dishwasher is not cleaning properly.

3. Water Temperature

The water in your dishwasher should reach at least 50 degrees Celsius (120 degrees Fahrenheit) to clean dishes properly. If your dishwasher is not cleaning properly, it could be due to the water temperature.

Solution: Some dishwashers automatically heat water to this ideal temperature. If yours doesn’t, check that the water heater is set as close to 50 degrees Celsius as possible. You can also turn on the kitchen sink for a minute before running the dishwasher to help ensure hot water flows into the machine from the very start of the wash cycle.

4. Faulty Soap Dispenser

A faulty soap dispenser may also be the issue. Often caused by a jammed dispenser door spring, this glitch can prohibit detergent from releasing at the proper time during the wash cycle, meaning your dishwasher is not cleaning properly.

Solution: Mix hot water and vinegar and use the solution along with a small brush to clean gunk and grease off the springs and soap dispenser. If your spring or dispenser door is broken, it will have to be replaced. And if the gasket around the dispenser is cracked, you’ll need to replace that too.

5. Dirty Filter

Older dishwashers (pre-2010) come with a self-cleaning filter, but newer models have removable ones that can get clogged with small pieces of food if you don’t clean your filter every month or two. This can be a reason why your dishwasher is not cleaning properly.

Solution: Locate the filter under the racks and remove it from the machine (you may have to twist off the cap first). Rinse it under hot running water, and if you see gunk and grime stuck to the filter, let it sit in soapy hot water for a few minutes or overnight in vinegar. Scrub it with an old toothbrush, rinse, and reinstall.

6. Clogged Spray Arm

In your washer, there are spinning spray arms that shoot water through tiny holes, called jets, to clean your dishes. If the jets are clogged, the water pressure suffers, meaning your dishwasher is not cleaning properly.

Solution: Detach the spray arm (check your user’s manual to find out if it snaps off or requires you to remove a screw), then scrub it with a soft brush and dish soap. Use a toothpick to unclog the holes. Run hot water over the spray arm. It’s a good idea to spin the spray arms yourself to confirm they’re rotating fluidly. If you notice something blocking them, remove it and try again.

7. Broken Inlet Valve

If you’ve tried the previous tips and your dishwasher still isn’t cleaning well, you could have a problem with the inlet valve. That’s the part that enables water to flow into the machine. Another sign your inlet valve is busted: You hear a hammering noise during the wash cycle. This could be the reason why your dishwasher is not cleaning properly.

Solution: Fixing it can be complicated, so check your owner’s manual to see if you want to order and install a replacement water inlet valve or contact an expert.

8. Hard Water

If the water in your home leaves a chalky residue on whatever it touches, you have hard water—H20 that’s filled with a lot of minerals, like calcium and magnesium. Hard water can also leave residue inside your dishwasher, affecting its efficiency and lifespan, and causing your dishwasher not to clean properly.

Solution: The best thing to do is install a water softener on the water line coming into your home to help control the damage from mineral deposits.
