Is your Asko dishwasher not draining properly? This problem can turn a simple dishwashing task into a frustrating chore.
You might notice water pooling at the bottom or dishes coming out still dirty. If you’re wondering why this is happening and how to fix it quickly, you’re in the right place. Keep reading to discover easy steps that can help you get your dishwasher draining like new again—saving you time, money, and hassle.
Common Causes Of Drainage Issues
Drainage problems are common in Asko dishwashers. These issues stop water from leaving the machine properly. Understanding the common causes helps to fix the problem faster. Several parts can block or stop the water flow. Finding the exact cause is the first step to repair.
Clogged Filters And Drains
Filters catch food particles and debris during washing. Over time, these can build up and block water flow. A clogged filter stops water from draining fully. Cleaning filters regularly keeps the dishwasher draining well. The drain area can also get blocked by dirt and residue.
Blocked Drain Hose
The drain hose carries water out of the dishwasher. Dirt, food scraps, or grease can block this hose. A blocked drain hose stops water from moving out. Checking and cleaning the hose clears any blockages. This simple step often solves drainage issues.
Faulty Drain Pump
The drain pump pushes water out of the dishwasher. If the pump is broken or worn out, water won’t drain. A faulty pump needs repair or replacement. Signs include strange noises or no water movement during drain cycles. Testing the pump helps identify this problem.
Kinked Or Damaged Hoses
Hoses can bend or get damaged over time. Kinks or holes block water flow or cause leaks. Inspecting hoses for damage is important. Fixing or replacing damaged hoses restores proper drainage. Smooth, undamaged hoses allow water to flow freely.

Tools You’ll Need
Fixing an Asko dishwasher that does not drain requires some tools. Having the right tools makes the job easier and safer. Prepare these items before starting any repair work. It helps avoid delays and frustration during the process.
Basic Hand Tools
Start with simple hand tools like screwdrivers and pliers. A flathead and a Phillips screwdriver are essential. Pliers help to grip and pull small parts. A wrench set might be needed to loosen bolts. These tools assist in opening panels and removing components.
Multimeter For Electrical Checks
A multimeter is useful to test electrical parts. It measures voltage, resistance, and continuity. Use it to check the dishwasher’s pump and wiring. This tool helps find electrical faults that block draining. It prevents guessing and saves time on repairs.
Bucket And Towels
Prepare a bucket to catch any water spills. Towels help clean up wet areas quickly. These items keep your workspace dry and safe. Water can leak when removing hoses or parts. Having towels and a bucket ready avoids mess and damage.
Step-by-step Cleaning Guide
Fixing an Asko dishwasher that does not drain starts with a thorough cleaning. Dirt and food bits often block parts inside the machine. Cleaning these parts can solve the problem quickly. Follow this step-by-step guide to clean your dishwasher and help it drain well again.
Removing And Cleaning Filters
First, open the dishwasher door and locate the filters at the bottom. Turn the filter counterclockwise to unlock it. Pull the filter out carefully. Rinse the filter under warm running water. Use a soft brush to remove stuck debris. Check the filter mesh for holes or tears. Replace the filter if it is damaged. Clean the filter area inside the dishwasher too. Put the filter back and lock it by turning clockwise.
Clearing The Drain Hose
Next, find the drain hose connected to the dishwasher. Disconnect the hose from the sink drain or garbage disposal. Use a long flexible brush or a cloth to clear blockages inside the hose. Flush the hose with water to remove any leftover debris. Check the hose for cracks or kinks. Replace the hose if damaged. Reattach the hose firmly to prevent leaks.
Inspecting And Cleaning The Drain Pump
Locate the drain pump at the bottom of the dishwasher. Remove the access panel to reach the pump. Check the pump area for food particles or small objects. Remove any debris carefully to avoid damage. Spin the pump impeller gently to ensure it moves freely. Clean the pump cover and seals. Reassemble all parts and secure the panel. This step helps water flow out smoothly.

Checking The Drain Pump Function
Checking the drain pump function is important when your Asko dishwasher is not draining. The drain pump moves water out of the dishwasher after washing. If the pump does not work well, water stays inside. This can cause bad smells and poor cleaning. Testing the drain pump helps find if it needs repair or replacement. Follow these steps to check the pump’s condition.
Testing For Electrical Continuity
Unplug the dishwasher before testing to stay safe. Remove the drain pump from the dishwasher. Use a multimeter to check electrical continuity on the pump’s terminals. A reading close to zero means the pump is good. If the meter shows no continuity, the pump is broken. This test shows if the pump motor can work properly or not.
Listening For Unusual Noises
Turn the dishwasher on and listen carefully. The drain pump should make a soft humming sound. Loud grinding or buzzing noises may mean the pump is stuck or damaged. Strange sounds often signal debris inside the pump or a worn motor. Pay attention to these sounds during the drain cycle for clues about pump health.
Replacing A Faulty Pump
Buy a new drain pump that fits your Asko dishwasher model. Disconnect power and water supply before starting. Remove the old pump carefully by loosening screws and hoses. Install the new pump in the same position. Reattach all connections firmly. Test the dishwasher to confirm the new pump drains water properly. Replacing a bad pump restores dishwasher drainage and performance.
Preventing Future Drainage Problems
Preventing future drainage problems in your Asko dishwasher helps keep it working well. Small steps can stop blockages and leaks. Regular care extends the life of your appliance. This section shares easy tips to avoid drainage issues.
Regular Maintenance Tips
Clean the filter at least once a month. Remove food scraps to stop clogs. Check the drain hose for bends or cracks. Clear any debris blocking the hose. Run a dishwasher cleaner every few months. This removes grease and mineral buildup. Keep the door gasket clean and dry. It helps prevent leaks and damage.
Proper Loading Practices
Load dishes without blocking spray arms. Place large items at the sides, not the center. Avoid overloading the dishwasher. Overcrowding stops water from draining well. Rinse off large food pieces before loading. This reduces the chance of clogging filters and drains. Arrange items so water can reach all surfaces.
Using The Right Detergents
Choose detergents made for dishwashers only. Avoid using regular dish soap. It creates too many suds and clogs drains. Follow the detergent instructions carefully. Use the correct amount for your water type. Hard water may need more detergent. Use rinse aid to help water flow off dishes. This keeps the drain clear and clean.
When To Call A Professional
Knowing when to call a professional for your Asko dishwasher not draining saves time and stress. Some problems need expert skills and tools. Trying to fix complex issues alone may cause more damage. A professional can quickly identify the cause and fix it safely.
Signs Of Complex Electrical Issues
Electrical problems can stop the dishwasher from draining properly. Flickering lights, burning smells, or the machine not starting are warning signs. If the dishwasher trips your home’s circuit breaker, it needs expert care. Professionals check wiring, sensors, and control boards to find hidden faults. Avoid using the dishwasher until a technician inspects it.
Warranty And Service Considerations
Check your Asko dishwasher warranty before repairs. Opening the machine or fixing it yourself might void the warranty. A certified technician ensures repairs follow warranty rules. Using authorized service centers protects your rights and maintains warranty coverage. Keep your proof of purchase and warranty papers ready for service calls.
