Before calling in help for Smeg dishwasher repair, take a moment to check the code and try the quick fixes below.

How Smeg Dishwasher Error Codes Work

Depending on your model, your Smeg dishwasher may display faults via:

A digital display with codes like “E2”, “E3” etc.
Flashing LED lights in specific sequences rather than text codes.

In either case, note the code exactly and consult your manual — these steps will help you interpret and often fix the issue without waiting for an engineer.

Comprehensive List of Smeg Dishwasher Error Codes & Fixes

Error E1 / E9 Smeg Dishwasher

Meaning: Overfill or flood protection activated (too much water or leak detected).
Fix: Turn off the water supply and unplug the machine. Check for leaks beneath the unit, inspect the inlet hose and valve, clear any blocked filters. If the error recurs, the sensor or inlet valve may need replacing.

Error E2 Smeg Dishwasher

Meaning: Overfill or water level fault (depending on model) — water level too high or float/trap fault.
Fix: Check water inlet hose and valve, ensure proper installation of the machine (level and drainage correct). Clean float switch and pressure trap if applicable.

Error E3 Smeg Dishwasher

Meaning: Heating fault — water not heating as required.
Fix: Test the heating element for continuity, check wiring and connections. If an element is faulty or thermostat causing issue, replace accordingly.

Error E4 Smeg Dishwasher

Meaning: Temperature sensor or thermistor fault — temperature reading incorrect or disconnected.
Fix: Inspect sensor wiring, test thermistor resistance, replace sensor if out of range or open circuit.

Error E5 Smeg Dishwasher

Meaning: Water fill fault — insufficient water entering the machine.
Fix: Ensure water supply tap is fully open, check and clean inlet hose and mesh filter, verify inlet valve operation.

Error E6 Smeg Dishwasher

Meaning: Drainage fault — water not draining within expected time.
Fix: Remove and clean drain filter, inspect drain hose for blockages or kinks, test pump for operation or replace if faulty.

Error E7 Smeg Dishwasher

Meaning: Flow meter detection when not fitted (models with LED flash codes) or water distribution problem.
Fix: Reset the unit by switching off for a few minutes, check wiring to flow sensor or correct installation of spray arms and water distribution valves.

Error E8 Smeg Dishwasher

Meaning: Read/test fault or waiting status (not always a direct error).
Fix: Reset dishwasher, cancel programme and start a new cycle. If code persists, inspect control board communications.

Error E10 Smeg Dishwasher**

Meaning: Circulation pump or motor fault (referenced in some guides).
Fix: Check pump impeller for debris, test pump motor continuity, replace pump if necessary.

Error E12 Smeg Dishwasher**

Meaning: Overfill / flood sensor or water leak detection (in some models).
Fix: Inspect base tray for water, dry area fully, reset machine, if flood sensor triggered repeatedly check inlet valve and base for leak.

Error F1–F15 Smeg Dishwasher**

Meaning: On certain models, other codes such as F1 (water inlet), F4 (overflow), F5 (motor fault) etc. appear in American‑published lists.
Fix: Refer to model‑specific manual for exact code mapping, but typical fixes include checking valves, overflow sensors, motor/pump units and control boards.

General Troubleshooting Tips for Smeg Dishwashers

Check water supply and pressure: Low pressure, half‑open taps or kinked hoses are very common in London flats.
Keep filters clean: Regularly remove and rinse the inlet filter and drain filter to avoid fault codes related to flow or overflow.
Ensure proper installation & drainage height: Drain hose must be elevated to prevent back‑siphon into the base tray, which can trigger overflow/flood protection logic.
Use correct detergent and avoid excessive foam: Too much foam can confuse level sensors and trigger E1/E2 overfill faults.
Reset before calling engineer: Turn off power at the wall for a few minutes, then restart — sometimes the control board resets and clears temporary faults.
