Dishwasher Error Codes

Smeg dishwashers are designed for efficient cleaning with advanced sensors and safety systems. When an issue occurs, error codes help identify the problem early, protecting internal components and ensuring consistent performance. Understanding these codes allows you to troubleshoot quickly and determine when part replacement may be required.

Below is a refined and slightly more detailed guide to common Smeg dishwasher error codes, their causes, and solutions.

Dishwasher Error Codes
Error Code
Causes & Solutions
E01
Anti-Flood / Water Leakage Error

Issue:- The dishwasher detects water leakage or activates anti-flood protection.

Possible Causes & Solutions:

  • Water collected in the base tray – Tilt the appliance slightly (after disconnecting power) to drain excess water, then identify the source of leakage.
  • Loose or damaged hoses – Inspect inlet and drain hoses for cracks, wear, or loose connections and tighten or replace as needed.
  • Faulty door seal – Check the rubber gasket around the door for gaps, dirt, or damage, and clean or replace it if necessary.
E02
Water Fill Error

Issue:- Dishwasher is not filling with water properly.

Possible Causes & Solutions:

  • Water supply turned off or low pressure – Ensure the tap is fully open and water pressure is sufficient for proper operation.
  • Inlet hose kinked or blocked – Straighten the hose and remove any obstructions restricting water flow.
  • Inlet valve clogged or faulty – Clean the filter screen in the valve or replace the valve if water flow remains restricted.
E03
Drainage Error

Issue:- Water is not draining from the dishwasher.

Possible Causes & Solutions:

  • Blocked drain hose or filter – Remove and clean filters and check the hose for food debris or buildup.
  • Drain pump obstruction – Inspect the pump area for small objects like glass or food particles, and clear carefully.
  • Improper hose installation – Ensure the drain hose is positioned correctly without bends or excessive height.
E04
Overfilling Error

Issue:- Excess water level detected inside the dishwasher.

Possible Causes & Solutions:

  • Faulty water inlet valve – The valve may not be shutting off properly and should be inspected or replaced.
  • Pressure switch malfunction – Check if the water level sensor is working correctly and replace it if defective.
  • Excess detergent causing foam – Use the recommended detergent type and quantity to prevent false overfill readings.
E05
Temperature Sensor Error

Issue:- Dishwasher cannot detect or regulate water temperature properly.

Possible Causes & Solutions:

  • Faulty temperature sensor – Restart the appliance to rule out a temporary glitch; replace if the issue persists.
  • Wiring or connection issue – Inspect accessible wiring for loose or damaged connections.
  • Limescale buildup – Clean internal components regularly to avoid interference with temperature sensing.
E06
Heating Element Error

Issue:- Water is not heating during the wash cycle.

Possible Causes & Solutions:

  • Burnt or damaged heating element – Inspect for visible damage and replace if heating is not occurring.
  • Control board not supplying power – Reset the unit or seek professional diagnosis if heating fails repeatedly.
  • Limescale affecting performance – Descale the dishwasher to improve heating efficiency.
E07
Circulation Pump Error

Issue:- Water is not circulating properly inside the dishwasher.

Possible Causes & Solutions:

  • Pump blocked by debris – Clean the pump area to remove food particles or foreign objects.
  • Worn or damaged pump motor – Listen for unusual noise and replace the pump if it fails to operate.
  • Low water level – Ensure proper filling to allow effective circulation during cycles.
E08
Spray Arm / Distribution Error

Issue:- Spray arms are not rotating or distributing water evenly.

Possible Causes & Solutions:

  • Spray arms clogged – Remove and clean holes to restore proper water flow.
  • Obstruction from dishes – Arrange dishes properly to allow free movement of the spray arms.
  • Loose spray arm fitting – Ensure arms are securely attached and rotate freely.
E09
Control Board / Electronic Error

Issue:- Dishwasher behaves unpredictably or shows persistent faults.

Possible Causes & Solutions:

  • Temporary system glitch – Turn off, unplug, wait a few minutes, and restart the appliance.
  • Power fluctuation – Use a stable power supply or surge protector to prevent damage.
  • Internal electronic failure – Control board may need professional repair or replacement.
E10
Door Lock / Safety Switch Error

Issue:- Dishwasher does not start due to a door locking issue.

Possible Causes & Solutions:

  • Door not fully closed – Press the door firmly until it clicks into the locked position.
  • Faulty door latch mechanism – Inspect for wear or misalignment and replace if necessary.
  • Wiring issue in lock system – Check connections if accessible or consult a technician.

Troubleshooting Tips

  • Clean Regularly: Keep condenser coils, vents, and interior surfaces free from dust and debris.
  • Avoid Overloading: Proper airflow is essential for maintaining consistent cooling performance.
  • Check Door Seals: Ensure gaskets are clean and sealing tightly to prevent temperature loss.
  • Defrost When Needed: Prevent excessive frost buildup that can impact efficiency.
  • Maintain Power Stability: Use a voltage stabilizer to protect electronic components.
