5 Common Dishwasher Problems - Tips and Tricks To Fix5 Common Dishwasher Problems and How to Fix

1. Dishwasher Does Not Turn On

Your dishwasher is not turning on. Ensure that your dishwasher is properly powered. Verify that the appliance is plugged into the electrical outlet and inspect the circuit breaker as well. For added assurance, you can connect the dishwasher to a different outlet that you are certain has electrical flow.

Secure the dishwasher door firmly by engaging the latch. A loosely closed or improperly latched door can often prevent the dishwasher from operating. To rule out issues with the latch or door, close and securely latch the door. For this step, it may be beneficial to have someone assist you. While maintaining a tight grip on the latch, initiate the dishwasher’s cycle. If the machine starts, you’ve identified a defective latch as the culprit.

Evaluate your home’s hot water supply. Some dishwashers necessitate a minimum water temperature for optimal cleaning. Test the hot water from your sink to confirm its availability. Bear in mind that many dishwasher models require the water to be at a minimum of 120 degrees Fahrenheit to function as intended.

Pro Tip: Always exercise caution while working with electrical components. If you’re unsure at any step, it may be best to consult with a professional appliance repair technician.

2. Water Is Leaking Through Dishwasher Door

If you notice a small puddle forming around your dishwasher due to a leaking door, it may be time to replace the door gasket. The gasket is a rubber or vinyl strip within the door frame designed to contain water inside the appliance.

Inspect the condition of your existing gasket by opening the dishwasher door. Over time, the gasket can wear out, and any tears, trapped debris, or other damage may compromise its sealing ability. If the gasket appears faulty, replacement units can be found at local hardware stores or online, tailored to your specific dishwasher model.

Install the new gasket ensuring it fits snugly around the door frame without any bulges or gaps. Secure it in place with the appropriate screws. After installation, run a test cycle to confirm that the issue has been resolved.

Extra Tip: When purchasing a new gasket, it’s advisable to refer to your dishwasher’s user manual or model number to ensure compatibility.

3. Dishes Not Drying Properly

While rinse aid is a frequently used remedy for dish-drying issues, persistent problems may point to a malfunctioning heating element in your dishwasher. A faulty heating element can lead not only to poorly dried dishes but also to the formation of white residue.

The design of the heating element can vary among dishwasher models, but it typically assumes a circular, “W,” or “U” shape, especially in newer units. It may even resemble the heating element in your oven or look like a heating plate. You’ll generally find it situated near the bottom of your dishwasher.

To inspect the heating element, first ensure that the dishwasher is disconnected from the power supply. Check the element for any signs of discoloration or darkened areas, which could indicate burnout. If the element appears to be in good condition, proceed to the next step.

With the power still disconnected, remove the front panel of your dishwasher to inspect the terminals and connectors underneath. Look for signs of wear, loose connections, or corrosion.

Pro Tip: Before attempting to remove the front panel, consult your dishwasher’s service manual for specific guidance.

If you find any of these problems with your heating element, it will likely have to be replaced, and if this is the case, they can be found online below.

4. Dishwasher Has Water In Bottom Of Unit

The likely reason for water in bottom of dishwasher is that your drain hose is positioned flat under the sink, which can allow water to flow back into the dishwasher.

To prevent this, elevate the drain hose using a twist-tie or zip-tie, positioning it as high as possible under the sink. The dishwasher’s pump expels water out, but if the hose isn’t elevated, gravity can cause the water to flow back into the appliance after the pump stops. This elevated hose setup is known as a High Drain Loop.

Extra Tip: Implementing a High Drain Loop is not only a preventative measure but also often a requirement according to many dishwasher installation guidelines. Failure to do so may void your warranty.

5. Dishwasher Is Emitting A Bad Smell

Eliminating unpleasant odors from your home is a priority for most homeowners. Here’s how to ensure your dishwasher not only keeps your dishes sparkling but also smells fresh:

  1. Check or Replace the Drain Filter:
    Often the primary source of foul odors, the filter can collect food particles that, if not cleaned regularly, can decompose and cause a stench. Maintain a clean filter or, if it’s been neglected for some time, consider purchasing a replacement from a local hardware store or online.
  2. Inspect the Door Gasket:
    Accumulated food particles on older door gaskets can contribute to unpleasant smells. Wipe down the gasket using a mixture of hot water and vinegar to help eliminate these odors.
  3. Maintain Your Garbage Disposal:
    Since the drain hoses of garbage disposals are often connected to dishwashers, food waste can sometimes backflow into the dishwasher hose. To address this, disconnect the power to your garbage disposal and detach the hose. Using a thick wire wrapped in a damp cloth, clean the interior of the hose.

Pro Tip: Always refer to your appliance’s user manuals for maintenance guidelines. If you’re not comfortable performing these tasks, it might be a good idea to consult a qualified appliance repair technician.

  1. lg1452WFEN2 DISH WASHER after removing, cleaning and reassembling all parts in the dish washer interior and replacing the drain pump I now have a leak across the bottom of the door ,not the bottom corners, this occurs at stages of the washing cycle I am assuming that the seal across the bottom of the door may have lost its flexibility. What do you think? and how should I go about replacing it Thank you Jim

    Roopnath Banerjee,
    If detergent is scattered when using your IFB Neptune dishwasher, this is a sign that the door that holds the detergent is opening up prematurely.
    If the detergent door is broken, you can try to troubleshoot it and see if it’s a simple spring issue and fix it yourself.

    KitchenAid KUDS30FXPA4 is making vibrating noise…loud all the time while washing. Just started. 4 years old. Pretty much same constant tone…started when started cycle . I can hear movement of water. Washing sounds quiet. But the vibration sound is loud and constant during wash cycle. When washer drain no such sound. Just regular quiet noise.

    What’s your diagnosis?

  6. I have a whirlpool dishwasher model # wdt730pazo.
    The dishwasher turns on and it fills with water.
    It does not wash. No water comes out of the spray arms.
    you can’t hear the motor running.
    What can be the matter with it ?

  7. I have the SD-2202S tabletop dishwasher. I took it apart (inside) and when reassembling it the spray arm seemed too close to the dishrack. It seems to be working ok but i usually put in smaller loads. How far apart should the sprayer be from the dishrack?

    My frigidaire gallery dishwasher displayed 99+ washing. Switching on quick clean did not working.

  9. My AEG Favorit 80860 U dishwasher does not work and shows after about 5 seconds the red display “Service i31”

  10. MAYTAG JETCLEAN #MDBH979SAB stops after washing cycle then sends “CANCEL” message that inactivates the surge protector plug. Is this a common problem?
