AEG Dishwasher Error Codes i20

How to Understand and Fix the AEG Dishwasher Error Code i20

Generally speaking, AEG dishwashers work quite well without any hiccups. However, one common glitch that occurs on an extremely minor note is seeing the error code i20 on one’s dishwasher display. One would most likely be accompanied by the shared issue in many people. Basically, this means a fault that revolves around improper draining, which normally does not include massive troubleshooting processes with the correct instruction.

This blog explains exactly what the i20 error code means, why it happens, and how you can fix it with step-by-step steps.

What Does the i20 Error Code Mean?

The i20 fault signals that there is an issue with your AEG dishwasher draining properly. In other words, the appliance thinks that there must be a blockage or blockage in allowing water to move freely through the drain system.

This could be due to a blocked filter, kinked drain hose, or even a problem with the pump. Fortunately, you can sometimes identify and fix the problem yourself without the help of a repair technician.

Possible Causes of the i20 Error Code

Understanding the root causes of the i20 error is the first step towards fixing it. Here are the most common culprits to check for:

Clogged Filters:
Food particles, grease, or debris can accumulate in your dishwasher’s filter, causing blockages that prevent water from draining.

Blocked or Kinked Drain Hose: It could be twisted, clogged, or blocked by something, disturbing the natural flow of water.

Faulty Drain Pump:
The drain pump that moves water out of the dishwasher may be clogged with debris or damaged.

Sudden Spike in Foam: Too much detergent or the wrong type of detergent for a dishwasher can cause a suds overflow that the dishwasher may interpret as a problem with draining.

Pressure Switch or Sensor Issues: Sometimes, anomalies in water flow send the wrong signals from internal sensors or switches.

Step-by-Step Instructions for Repairing the i20 Error Code

To rectify this challenge, follow the following easy, yet elaborative steps. Remember to always unplug your dishwasher from its power supply when doing any type of maintenance for your safety.

Step 1: Cleaning the filters

The filter is usually on the bottom area of the dishwasher.
Take them out and rinse them thoroughly under warm, running water; use a soft brush to remove the debris stuck. Put them securely back in again to make sure that their seating is all proper.

Step 2: The drain hose should next be checked for visible kink and twists or clogs.

Most hoses are actually attached to your sink drain or a plumbing.
Unhook this hose drainage and check from both ends of a blockage site. If you see blockage, clean the hose by running warm water through it or by flushing it with a gentle stream from a garden hose.

Step 3: Clean the Drain Pump

Open the drain pump area, usually located at the bottom of the dishwasher, near the filters.
Remove food particles, splinters, or foreign objects that may be impeding the operation of the pump. Be careful—sharp objects like broken glass can sometimes lodge in this area.

Step 4: Reduce Foam Build-Up

If excessive foam is an issue, run the dishwasher without detergent for a short cycle to flush out the suds.
Going forward, ensure you’re using the correct detergent in the appropriate amount for your model.

Step 5: Check Sensors and Pressure Switches

If all of the above does not resolve the problem, sensors or internal components may need attention. A quick reset might help—turn off the power at the mains, wait 5 minutes, and restart the dishwasher. If the problem persists, this may require professional diagnosis and repair.

When Should You Call a Professional?

If you’ve followed all the steps above and the i20 error code still appears, it’s time to call in a technician. Issues with internal components like sensors, pressure switches, or the drain pump motor itself are often more complex and best handled by an expert.

AEG has an exceptional support network, as well as authorised technicians specializing in solving such problems. Remember to have your dishwasher model number with you when contacting the support, which will expedite troubleshooting.

Tips to Prevent Future i20 Errors

Though experiencing an i20 error may be quite common for anybody, still there is the possibility to decrease its recurrence with some precautionary measures:

Clean the Filters Regularly: Try to clean the filters every two weeks to avoid clogs building up.

Check Drain Hoses Periodically: Make sure the hose isn’t twisted or blocked on routine cleaning.

Use the Right Detergent: Use only high-quality dishwasher detergent and avoid overloading the detergent dispenser.

Rinse Dishware Before Loading: While AEG dishwashers are pretty good at breaking down residue, the removal of large food scraps can help prevent blockages.

The Bottom Line

The i20 error on your AEG dishwasher is quite inconvenient; it’s mostly quite easy to fix if you know how to approach it. Following the steps above, you can locate the problem, fix it, and have your dishwasher working perfectly again. In cases where the issue is beyond your repair, feel free to contact AEG’s support team for help.

With a little TLC, your dishwasher will keep on cranking out sparkling dishes without interruption.
