The E5 error code on your Smeg dishwasher indicates an issue with water filling. This typically happens at the beginning of a cycle when the dishwasher isn’t able to reach the expected water level within a set timeframe (usually around 7 minutes).

Here are some steps you can follow to troubleshoot the Smeg dishwasher E5 error code:
1. Check the water supply:
- Ensure the water shutoff valve connected to your dishwasher is fully open. A closed valve will prevent water from entering the appliance.
2. Inspect for blockages:
- A clogged water inlet valve filter can restrict water flow. Locate the dishwasher’s filter (often near the water inlet valve) and clean it according to your user manual.
3. Verify the inlet hose:
- Make sure the dishwasher’s inlet hose isn’t bent or kinked. A kinked hose can restrict water flow and prevent the dishwasher from filling properly.
4. Consider the solenoid valve (if troubleshooting above fails):
- In rare instances, a malfunctioning solenoid valve, which controls water flow, could be the culprit. If you’re comfortable with electrical troubleshooting, you can use a multimeter to check the valve for faults.
For your reference:
- If you’re unsure about any steps or feel uncomfortable performing them yourself, consult your Smeg dishwasher manual or contact a qualified appliance repair professional.
- Regularly cleaning the dishwasher filter can help prevent future E5 errors caused by blockages.
By following these steps, you should be able to identify and address the cause of the E5 error code in your Smeg dishwasher.
