How to Fix a Dishwasher That Is Not Draining

Is your dishwasher not draining properly? Don’t panic! Follow our expert guide to diagnose and fix the issue quickly and efficiently. Whether it’s a simple blockage or a more complex problem, we’ve got you covered.

Dishwashers are amazing machines when they work right! Unfortunately, they aren’t immune to problems, and when they do occur, it can be very difficult to know what to do. So, if your dishwasher suddenly stops draining, how do you go about fixing it?

While your first thought might be the pump or drain, these are only two of the common causes of a dishwasher not draining. Remember, while you might be able to fix the problem yourself, the best option is often to call in a professional dishwasher repair engineer. However, we can help you identify the problem, and who knows, you might be lucky and find a simple, quick fix! Let’s take a look at the possible reasons why your dishwasher could be refusing to drain and how you can address them.

Step 1: Inspect the Drain

Let’s get the big one out of the way, first shall we? Start by checking the drain, which is the most common issue. Since there are many models and types of dishwashers, consult your instruction manual to find out where your drain is located and how you can access it. Once you have access, look for any visible obstructions. If your pump features a motor and there are no noticeable obstructions, the issue could be with the motor itself. If locating the drain is problematic, it’s best to call in a professional dishwasher repair technician to avoid causing more harm.

Step 2: Examine the Food Chopper

The food chopper can also become blocked and cause drainage problems. After locating the chopper, check for any visible obstructions. If there are none, see if the chopper can spin smoothly. If it doesn’t spin smoothly, it might be damaged internally and need replacement.

Step 3: Check the Timer

Modern dishwashers usually have a control panel with a built-in timer, while older models have a timer dial. Any kind of timer can cause drainage issues when it malfunctions. Use a multi-meter to check for timer issues, but remember that any complex rewiring or replacements should be handled by an experienced repairman.

Step 4: Inspect the Drain Hose

The drain hose is another area that often gets overlooked. If the front of the drain is clear, it’s easy to assume the drain isn’t the problem, but blockages often occur deeper in the drain hose. A clogged or restricted drain hose will prevent your dishwasher from draining properly. Check for kinks in the hose, as these can lead to larger problems if left unchecked. Food waste or other debris could also be blocking the hose. Checking and removing these blockages requires experienced hands and some disassembly of your dishwasher. If you suspect a blockage in the drain hose, it’s best to call in a dishwasher repair company.

Step 5: Assess the Drain Belt

For models that feature drain belts, this should be one of the first things you check. A drain belt is used on belt-driven pumps and is common in older models of dishwashers. If the belt loses its grip or comes off the motor, your dishwasher will stop draining. Inspecting the belt is usually straightforward. If the belt has just come off the pump and is undamaged, it can be reattached. However, if it’s damaged, it will need to be replaced. You may need an expert to handle this repair. Solving a dishwasher drainage problem can be messy, but in many cases, the fix is straightforward.

These steps will help you identify the issue, but for more complex problems, calling in an experienced repairman is the best course of action. Our tips aim to guide you through the process, whether you fix it yourself or seek professional help.
