SMEG Dishwashers Error Codes

E1

Dishwasher will not fill with water; cycle starts then stops with E1 on display and audible beeps.

Water Inlet Timeout / No Fill

E10

Dishwasher shows E10 and may not soften water correctly; salt light may behave erratically.

Water Softener / Regeneration Valve Fault

E11

Dishwasher displays E11 and may not detect water temperature correctly; cycles may end prematurely or run indefinitely.

NTC Temperature Sensor Fault

E12

Dishwasher shows E12 and may have issues with drying performance or fan operation on models with active drying.

Drying Fan / Condenser System Fault

E13

Dishwasher displays E13 and may not start; often associated with door lock or door switch issues.

Door Lock / Door Switch Fault

E14

Dishwasher shows E14 and may have irregular filling behavior; sometimes fills too little or too much.

Flow Meter / Water Intake Measurement Fault

E15

Dishwasher displays E15 and may not start; often related to communication or internal sensor errors on some SMEG platforms.

Internal Communication / Sensor Bus Error

E16

Dishwasher shows E16 and may stop during a cycle; sometimes associated with overfilling or drain issues on certain SMEG models.

Overfill / Drain Sensor Conflict

E17

Dishwasher displays E17 and may not start or may stop unexpectedly; often linked to power supply or voltage issues on some SMEG models.

Power Supply / Voltage Error

E18

Dishwasher shows E18 and may not fill correctly; sometimes indicates a low water level or short fill on certain SMEG models.

Short Fill / Low Water Level

E19

Dishwasher displays E19 and may have issues with the detergent or rinse aid dispenser on some SMEG models.

Dispenser Actuator / Rinse Aid System Fault

E2

Dishwasher stops mid-cycle with water left in the tub and displays E2; machine may attempt to drain repeatedly.

Drain Timeout / No Drain

E20

Dishwasher shows E20 and may not start or may stop with no other obvious symptom; used on some SMEG platforms for generic motor/triac faults.

Motor Drive / Triac Fault

E3

Dishwasher fills and circulates but does not heat; cycles run unusually long and end with E3 on the display.

Heating Circuit Failure

E4

Dishwasher stops and displays E4; machine may run the drain pump continuously and not accept new cycles.

Anti-Flood / Overflow Protection Activated

E5

Dishwasher displays E5 and may stop during the fill phase; sometimes water level appears too high or too low.

Water Level / Pressure Switch Error

E6

Dishwasher shows E6 and may not start the wash; sometimes accompanied by no spray action from arms.

Circulation Pump / Wash Motor Failure

E7

Dishwasher displays E7 and may stop shortly after starting; some models show E7 when the turbidity or optical sensor is faulty.

Turbidity / Optical Water Sensor Error

E8

Dishwasher shows E8 and may have poor water level or weak spray; sometimes associated with issues in the side water matrix or heat exchanger.

Water Distribution / Heat Exchanger Fault

E9

Dishwasher displays E9 and may stop heating or show irregular water levels; often linked to the heat pump assembly on newer SMEG models.

Heat Pump / Integrated Heater Fault

Symptom

Dishwasher causes excessive vibration or moves within the cabinet during operation.

Vibration / Installation Issue

Symptom

Dishwasher completes cycle but dishes are wet and not drying properly; condensation remains on walls and plastics.

Poor Drying Performance

Symptom

Dishwasher does not dispense detergent; tablet remains in the dispenser at end of cycle.

Detergent Dispenser Not Opening

Symptom

Dishwasher does not drain completely at the end of the cycle, leaving a pool of water in the sump.

Partial Drain / Residual Water

Symptom

Dishwasher does not power on at all; no lights or display, no response to buttons.

No Power / Dead Appliance

Symptom

Dishwasher door drops down quickly or will not stay in intermediate positions when opened.

Door Hinge / Spring Imbalance

Symptom

Dishwasher door is difficult to close or requires excessive force to latch.

Door Alignment / Latch Interference

Symptom

Dishwasher emits a burning smell or shows signs of overheating during operation.

Overheating / Electrical Burning

Symptom

Dishwasher fills with water but the spray arms do not rotate; dishes remain dirty and detergent may not dissolve fully.

No Circulation / Spray Arm Stoppage

Symptom

Dishwasher has a persistent bad smell, even when empty; odor transfers to dishes.

Odor / Biofilm Buildup

Symptom

Dishwasher interior light (on models equipped) does not turn on when the door is opened.

Interior Light Failure

Symptom

Dishwasher intermittently stops mid-cycle and resumes later, or pauses unexpectedly without an error code.

Intermittent Power / Overheat Protection

Symptom

Dishwasher leaks water from the bottom front of the door during or after a cycle.

Door Seal / Overflow Leak

Symptom

Dishwasher leaks water from underneath, often triggering the anti-flood safety and stopping the machine.

Base Leak / Internal Hose Failure

Symptom

Dishwasher leaves gritty particles or sand-like residue on dishes after the cycle.

Soil Retention / Poor Rinsing

Symptom

Dishwasher leaves white film or spots on glassware and dishes.

Limescale / Detergent Residue

Symptom

Dishwasher makes loud grinding or rattling noises during wash or drain phases.

Mechanical Noise / Foreign Object in Pump

Symptom

Dishwasher powers on but will not start a cycle; Start button unresponsive or program will not engage.

User Interface / Start Inhibit

Symptom

Dishwasher racks are difficult to slide or feel rough when pulled in and out.

Rack Rail / Wheel Wear

Symptom

Dishwasher runs but dishes come out dirty or with food residue, especially on the top rack.

Poor Wash Performance

Symptom

Dishwasher runs continuously or cycles take much longer than indicated, without showing an error code.

Extended Cycle / Sensor Misreading
