E3 Error Code on Your Smeg Dishwasher

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.

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.
