Electrolux Dishwasher i30 Error Code: Understanding, Causes, and Solutions

The i30 error code on your Electrolux dishwasher usually appears when there’s an issue related to water overflow or leaks. In technical terms, the i30 error is short for “Aqua Control Error.” This means that your dishwasher’s aqua control system has detected the presence of water in the drip tray, prompting it to display the i30 fault code. Essentially, it serves as an alert mechanism, signaling the possibility of a leakage or an unwanted surplus of water in an inappropriate location.

This proactive detection aims to prevent potential damage and ensure your dishwasher operates effectively. So, when you see the i30 error, it’s time to investigate leaks and take necessary actions to resolve the issue.

Common Causes of Electrolux Dishwasher i30 Error Code

Let’s explain each of these factors in more detail

  • Leakage at the water hydraulic circuit: This refers to the possibility of water leaking from the hoses that supply water to your dishwasher and the drainage hoses that carry away wastewater. Any cracks, pinholes, loose connections, or damaged hoses can result in water escaping and triggering the i30 error code.

  • If the inlet valve becomes faulty, it may fail to shut off the water properly after it has filled the dishwasher, leading to an overflow of water that accumulates in the bottom tray.
  • The dishwasher door features a rubber gasket encircling its perimeter, serving as a sealing mechanism. Its primary job is to create a watertight seal when the dishwasher is in use. If this gasket is damaged, worn, or not properly seated, it can allow water to leak out during the wash cycle, causing the i30 error.
  • The floating sensor is designed to detect water leaks in the drip tray. If it becomes blocked by debris, moisture, or foreign objects like screws, it may give incorrect readings, leading to the dishwasher’s belief that there is excess water. A faulty float microswitch can also fail to signal the correct water level to the control system, causing the i30 fault code.
  • A drainage issue can result in water not being properly removed from the dishwasher during or after the washing and/or rinse cycle. This can happen due to clogs in the drainage system, such as in the drain hose or the dishwasher’s pump, which can lead to water accumulating in the bottom tray and triggering the i30 error.

Effective Solutions to Fix Your Dishwasher i30 Error Code

If you come across the i30 error code on your appliance, don’t worry. Here are the troubleshooting steps to help you resolve the issue:

  • Start by inspecting the drain pump filter. Ensure it is clean and free from any debris or blockages that might be hindering proper water drainage.
  • Examine the water tank for any blockages, leaks, or cracks. Pay special attention to the hoses connecting the dishwasher to the water supply and drain. If you notice any water dripping from the hoses, tighten the connections securely or replace the hoses if they are damaged.
  • The float switch is a critical component in detecting water leaks. Confirm that the wiring harness connecting the float switch is properly secured.
  • Visually inspect the float switch itself. Ensure it moves freely. Any physical damage or blockage could affect its operation.
  • If the error persists after checking the float switch visually, use a multimeter to check the float microswitch for electrical continuity. A malfunctioning microswitch might need a replacement.

  • If all the above steps fail to resolve the i30 error code, it might indicate a more complex issue with the appliance’s main board. In such cases, it may be necessary to consider replacing the main control board as a final troubleshooting step.


By following the provided troubleshooting steps, you can address the i30 fault code on your Electrolux dishwasher with confidence. Remember to check for blockages, leaks, and the condition of essential components like the float switch.

Frequently Asked Questions (FAQs) about the Electrolux dishwasher i30 error code:

The i30 error code signifies an “Aqua Control Error,” indicating that your dishwasher’s aqua control system has detected water in the bottom tray. This is typically due to a water leakage or overflow issue.

If you notice water dripping from the hoses connecting your dishwasher to the water supply or drain, first try tightening the connections. If the dripping continues, it’s recommended to replace the damaged hoses to prevent further leakage and resolve the i30 error.

The float switch is a crucial component that detects the water level inside the dishwasher. If it’s obstructed, damaged, or malfunctioning, it can trigger the i30 fault code erroneously. It’s important to ensure the float switch moves freely and is in good working condition to avoid false error codes.
