Dishwasher Not Draining? Find Symptoms, Causes and Solutions | Helpful Tips
If you’ve noticed that your dishwasher is not draining properly, it can be frustrating and inconvenient. However, before you call a professional for help, there are a few things you can try on your own to fix the issue. Understanding the symptoms, causes, and possible solutions can potentially save you time and money.
One of the first signs that your dishwasher is not draining correctly is the presence of standing water at the bottom of the machine. If you open the door and see a pool of dirty water, it’s a clear indication that something is causing a blockage in the drain. Another symptom to watch out for is if your dishes are not fully clean or still show suds after a cycle. This could indicate that the drain is not able to remove all the water and detergent from the machine.
There are several possible causes for a dishwasher not draining properly. One common issue is a clogged drain hose or a blocked air gap. The drain hose is the plastic tube that connects the dishwasher to the garbage disposal or sink drain. Over time, food particles, grease, and other debris can accumulate in this hose, preventing proper drainage. Similarly, the air gap, which is usually located on the sink or countertop, can become clogged with food particles and needs to be cleaned.
Another reason your dishwasher may not be draining is a clogged drain pump or a malfunctioning drain solenoid. The drain pump is responsible for pumping water out of the machine, while the drain solenoid opens and closes to allow water to flow through. If either of these components is faulty, it can impede water drainage. Additionally, a faulty drain pump motor may not have enough power to push the water out, resulting in poor drainage or no drainage at all.
If you’re comfortable with DIY repairs and want to try fixing the issue yourself, there are a few solutions you can attempt. Before attempting any repairs, it’s essential to disconnect the dishwasher from the power supply to avoid any accidents. You can start by manually removing any visible debris or food particles from the drain and filters. Use a pair of pliers to remove any large objects that may be blocking the drain or drain pump.
If the dishwasher still won’t drain after manually clearing the blockage, you can try flushing the drain hose with water to dislodge any remaining debris. Connect the drain hose securely and pour a mixture of baking soda and vinegar or Drano into the dishwasher. Let the solution sit for a while to dissolve any clogging substances, then run a hot water wash cycle. This process can help clear the blockage and improve drainage.
If you’ve tried all the solutions mentioned above and your dishwasher still isn’t draining properly, it may be time to call a professional. Some issues, such as a frozen or damaged drain hose or faulty drain pump, may require specialized knowledge and tools to fix. A professional technician will be able to diagnose the problem and provide the most appropriate solution to get your dishwasher back in working order.
In conclusion, a dishwasher not draining can be a frustrating problem to deal with. By understanding the symptoms, causes, and possible solutions, you can save time and money by attempting to fix the issue yourself. However, if DIY repairs are not successful, it’s always best to reach out to a professional to ensure the problem is resolved correctly.
