The E3 error code on your Smeg dishwasher indicates an issue with the water heating function. This means the water isn’t reaching the desired temperature for proper cleaning.

E3 error code on your SMEG dishwasher

Here’s a breakdown of possible causes and solutions:

Possible Causes:

  • Faulty heater assembly: This is the most common culprit.
  • Loose electrical connections: Connections might have come loose over time.
  • Malfunctioning wash pump: If the water isn’t circulating, it won’t heat properly.
  • Electronic board failure: In rare cases, the control board might be faulty.

How to Fix the E3 Error Code on Your Smeg Dishwasher: Troubleshooting Guide

  1. Check the heating element.
    • Safety first: unplug your dishwasher before any troubleshooting.
    • Consult your user manual to locate the heating element.
    • Using a multimeter, set it to resistance measurement and measure the heating element. It should read around 25 ohms.
    • If the reading is “open” or significantly different, the heating element needs replacement.
  2. Inspect electrical connections.
    • Visually check for any loose or burned connections on the heating element and the electronic board.
    • Use a multimeter set to the “ohm” position to check continuity.
    • Secure any loose connections or replace damaged wires.
  3. Wash pump.
    • If the wash pump isn’t functioning correctly, water circulation will be impacted, hindering heating. Consider replacing the wash pump if the previous steps haven’t resolved the issue.
    • Note: Replacing the pump can be more complex and might require a qualified technician.
  4. Electronic board.
    • If all else fails, the issue might lie with the electronic board.
    • Checking the voltage at the heating element during the heating cycle requires advanced knowledge and a multimeter. In this case, consider consulting a qualified appliance repair technician.

By following these steps, you should be able to identify the cause of the E3 error code and get your Smeg dishwasher back to sparkling clean dishes.
