Owning an AEG dishwasher means enjoying the convenience of sparkling clean dishes with minimal effort. But what happens when your trusty appliance starts acting up? Don’t worry - I’ve been there, and I’m here to help you troubleshoot common AEG dishwasher issues with simple, clear steps. Whether your dishwasher won’t start, isn’t cleaning properly, or is leaking, this guide will walk you through practical solutions you can try before calling in a professional.
Understanding Common AEG Dishwasher Problems
Dishwashers are complex machines, but many problems have straightforward causes. Knowing what to look for can save you time and stress. Here are some frequent issues AEG dishwasher owners face:
Dishwasher won’t start or respond
Dishes come out dirty or spotted
Water won’t drain properly
Dishwasher leaks water
Strange noises during operation
Each of these problems has specific troubleshooting steps. Let’s break them down so you can tackle them confidently.

How to Fix an AEG Dishwasher That Won’t Start
If your dishwasher refuses to start, the first thing to check is the power supply. Make sure the appliance is plugged in securely and the socket is working. You can test the socket by plugging in another device.
Next, check the door latch. Dishwashers won’t start if the door isn’t properly closed or the latch is faulty. Open and close the door firmly until you hear a click.
If the power and door are fine, look at the control panel for error codes or flashing lights. These signals can indicate specific faults. Refer to your user manual for what each code means.
Sometimes, a simple reset can fix the problem. Turn off the dishwasher at the mains, wait a few minutes, then turn it back on. This can clear minor electronic glitches.
If none of these steps work, the issue might be with the internal wiring or the control board. At this point, it’s best to contact a professional repair service to avoid causing further damage.
Troubleshooting Poor Cleaning Performance
When your dishes come out dirty or spotted, it’s frustrating. Here’s how to improve cleaning results:
Check the spray arms - Remove and inspect them for blockages. Food particles or hard water deposits can clog the holes. Clean them with warm water and a soft brush.
Use the right detergent - Make sure you’re using a detergent designed for dishwashers. Avoid using too much or too little.
Load dishes correctly - Overloading or placing items incorrectly can block water flow. Ensure plates and bowls face the spray arms and don’t nest together.
Check the filter - A clogged filter reduces water circulation. Remove and clean it regularly.
Use rinse aid - This helps prevent spots and improves drying.
If your dishwasher still doesn’t clean well, the water inlet valve or pump might be faulty. These parts control water flow and pressure, and a professional can test and replace them if needed.

When Your Dishwasher Won’t Drain Properly
Water left at the bottom of the dishwasher after a cycle is a common problem. Here’s how to fix it:
Check the drain hose - Make sure it’s not kinked or clogged. Detach it and flush with water if necessary.
Clean the filter and sump - Food debris can block drainage. Remove and clean these parts carefully.
Inspect the drain pump - Sometimes small objects or broken glass can jam the pump. If you hear a humming noise but no drainage, the pump might be stuck.
Check the air gap - If your dishwasher has an air gap (a small cylinder near the sink), make sure it’s not blocked.
If these steps don’t solve the problem, the drain pump or electronic control might need professional attention.
What to Do If Your Dishwasher Is Leaking
Leaks can cause water damage and need immediate attention. Here’s how to identify and fix leaks:
Check door seals - Worn or dirty seals can let water escape. Clean the seals with a damp cloth and inspect for cracks or damage.
Inspect the detergent dispenser - If it doesn’t close properly, water can leak during the wash cycle.
Look under the dishwasher - Check hoses and connections for signs of leaks or loose fittings.
Avoid overfilling detergent - Too much detergent can cause excessive suds and leaks.
If you find a damaged seal or hose, replacing these parts usually stops the leak. For more complex leaks, such as from the pump or tub, professional repair is recommended.
