How to Clear Error Codes AEG 40850 Dishwasher

Dishwashers are magic for saving time and effort, but they can be baffling when they flash an error code you’ve never seen before. If you own an AEG 40850 dishwasher and you’re dealing with error codes, don’t panic it’s usually your appliance’s way of communicating that something needs attention.

This guide will explain what these error codes mean and walk you step-by-step through how to resolve them.

Common Error Codes on the AEG 40850 Dishwasher

Here are some of the most common error codes that might appear on your AEG 40850 dishwasher along with what they typically indicate:

  • i20/i30/i40 – Issues with water drainage.
  • i10 – Water supply problem.
  • i50 – A motor-related issue.
  • i60 – A heating issue, often tied to the water temperature.
  • iF0 – The dishwasher can’t detect water flow or sees a blockage.

If any of these codes appear on your dishwasher’s display panel, don’t worry. Most issues can be fixed with a little troubleshooting.


Step-by-Step Guide to Clearing Error Codes

Here’s a clear, actionable plan to help you troubleshoot and fix the problem your dishwasher is alerting you to.

1. Reset the Dishwasher

Sometimes a quick reset is all it takes to clear an error code. Here’s how to do it:

  • Turn off the dishwasher by pressing the power button.
  • Unplug the dishwasher from the power outlet. If it’s hardwired, switch it off at the circuit breaker.
  • Wait for 5 minutes to allow the system to fully reset.
  • Plug it back in and turn the dishwasher on.

Check if the error code has disappeared. If not, move on to the next steps.

2. Check the Filters and Drains

Error codes like i20, i30, or i40 often mean there’s an issue with draining. Here’s how to inspect the filters and drains:

  • Open the dishwasher and remove the bottom rack.
  • Locate the filter at the base of the machine (it usually looks like a circular mesh).
  • Pull out the filter and rinse it under warm water to remove any debris or grease buildup.
  • Check the surrounding drain area to ensure there are no food scraps or blockages.
  • Reinstall the filter securely and test the dishwasher.

3. Inspect the Water Supply

If you see an i10 error code, the dishwasher might not be getting enough water.

  • Make sure the water supply valve connected to your dishwasher is fully open.
  • Check the water inlet hose for kinks, blockages, or leaks.
  • Remove the hose and clean the small filter at the connection point (this often collects sediment over time).
  • Reattach the hose and try running the dishwasher again.

4. Examine the Spray Arms

Faulty spray arms could be causing iF0 or other water flow errors.

  • Remove the spray arms from the dishwasher by gently twisting or unclipping them.
  • Rinse them under running water and use a toothpick or fine wire to clear any blockages in the nozzles.
  • Reattach the spray arms correctly to ensure even water distribution.

5. Inspect Heating Elements

An i60 error code suggests there’s an issue with the heating elements. While accessing internal components is more technical, you can still try these steps first:

  • Run a cycle and check whether the water feels hot (be cautious to avoid burns).
  • If it doesn’t, consider calling an authorised service technician to inspect the heating element or thermostat.

6. Look for Visible Leaks

Leaks often trigger error codes like i30.

  • Check around and beneath the dishwasher for pooling water.
  • Inspect the door seal for cracks, tears, or debris that may prevent a proper seal.
  • If the seal looks damaged, it’s best to replace it to ensure watertight operation.

7. Run a Diagnostic Mode

Many AEG dishwashers, including the 40850, have a diagnostic mode to run self-checks. Check your user manual for instructions on how to activate diagnostic mode it might identify the problem directly and save time troubleshooting.

8. Contact Customer Support if Needed

If none of the above steps clear the error, it’s time to reach out to AEG’s customer service. Provide them with details about the error code, the steps you’ve already tried, and your dishwasher’s model information. Sometimes, the issue may require a specialised technician.

Tips for Preventing Future Errors

Once your dishwasher is back up and running, follow these best practices to keep those pesky error codes at bay.

  • Clean the filters and spray arms monthly.
  • Run the dishwasher regularly, including a hot wash cycle every couple of weeks to prevent grease buildup.
  • Avoid overloading the dishwasher, as it can block water flow.
  • Check for leaks and repair seals promptly if needed.
