What Does E2 Mean On A Dishwasher

In today’s fast-paced world, household appliances have become essential to our daily lives. Dishwashers, in particular, have simplified the daunting task of cleaning dishes and utensils. However, like any other machine, dishwashers can sometimes display error codes, leaving users puzzled. One such code is E2, which often appears on the dishwasher’s display panel. In this article, we’ll delve into what E2 means on a dishwasher and how to troubleshoot this common issue.

Understanding E2 Error Code

What is E2?

The E2 error code on a dishwasher is a signal that something isn’t quite right within the appliance’s internal systems. It’s essentially a way for the dishwasher to communicate that it has detected an issue that requires attention.

Possible Causes of E2 Error

To effectively address the E2 error code, it’s crucial to identify its root causes. Here are some common reasons why your dishwasher might be displaying E2:

1. Water Supply Issues

  • Blocked Water Inlet Valve: A clogged water inlet valve can restrict water flow into the dishwasher, triggering the E2 error.
  • Low Water Pressure: Insufficient water pressure can hinder the dishwasher’s ability to function properly, leading to error codes like E2.

2. Drainage Problems

  • Clogged Drainage Hose: A blocked drainage hose can prevent proper water drainage, causing the dishwasher to display E2.
  • Faulty Drain Pump: A malfunctioning drain pump can also contribute to drainage issues and trigger the error code.

3. Sensor Malfunction

  • Temperature Sensor Failure: The dishwasher relies on temperature sensors to regulate water temperature. If a sensor malfunctions, it can result in the E2 error.

Troubleshooting E2 Error

Now that we’ve identified potential causes, let’s explore how to troubleshoot and resolve the E2 error on your dishwasher:

1. Check Water Supply

  • Inspect the water inlet valve for any blockages. Clean or replace it if necessary.
  • Ensure that the water pressure is adequate for the dishwasher to function correctly.

2. Examine Drainage System

  • Inspect the drainage hose for clogs or kinks. Clear any obstructions.
  • Test the drain pump’s functionality. Replace it if it’s not working correctly.

3. Sensor Check

  • Have a technician check the temperature sensors for any faults. Replace them if needed.


In summary, the E2 error code on your dishwasher is a clear indicator that something is amiss. By understanding the potential causes and following the troubleshooting steps mentioned above, you can resolve the issue and have your dishwasher back in working order in no time.
