Siemens Refrigerators Error Codes

E1

Refrigerator compartment too warm while freezer seems normal; temperature alarm may sound and E1 appears on display.

Refrigerator Compartment Temperature Sensor Failure

E10

Alarm sounds and E10 appears; refrigerator may not cool; condenser fan may be off while compressor is running hot.

Condenser Fan Motor Fault

E11

E11 displayed; interior fan not running; uneven temperatures between shelves; frost may appear in some areas.

Evaporator Fan Motor Fault

E12

E12 error; refrigerator may not enter or exit SuperCool/SuperFreeze modes correctly; temperatures drift.

Mode Control / Relay Fault on Main PCB

E13

E13 displayed; water or ice dispenser (if fitted) not working correctly; may also see intermittent power loss to door functions.

Door Harness / Hinge Wiring Fault

E14

E14 error; water dispenser not dispensing or very slow; ice maker may not fill.

Water Inlet Valve or Flow Sensor Fault

E15

E15 displayed; ice maker not producing ice; may also show ice tray stuck or incomplete cycles.

Ice Maker Motor or Position Sensor Fault

E16

E16 error; interior lights may stay on or off incorrectly; door alarm may not function properly.

Door Switch / Reed Sensor Fault

E17

E17 displayed; refrigerator may not cool; compressor may not start; sometimes accompanied by clicking sounds.

Compressor Start Device / PTC Relay Fault (Non-Inverter Models)

E18

E18 error; refrigerator may show unusually high or low temperature readings not matching actual conditions.

Temperature Calibration / Sensor Range Error

E19

E19 displayed; audible alarm may sound; refrigerator may not cool properly; sometimes associated with power interruptions.

Power Supply / Low Voltage Detection Fault

E2

Freezer compartment not reaching set temperature; E2 error displayed; temperature alarm may be active.

Freezer Compartment Temperature Sensor Failure

E3

Refrigerator runs continuously or cycles erratically; display may show E3 and temperatures are inaccurate or unstable.

Ambient (Room) Temperature Sensor Failure

E4

Refrigerator or freezer temperature fluctuates; defrost seems irregular; E4 displayed on control panel.

Evaporator Temperature Sensor Failure

E5

Refrigerator displays E5 and may not defrost properly; ice builds up on the evaporator and airflow is reduced.

Defrost Heater Circuit Failure

E6

Refrigerator shows E6 and may not respond correctly to temperature changes; compressor may run continuously or not at all.

Main Control Board Communication or Internal Fault

E7

Display shows E7; interior lights or fans may behave erratically; some models show blank or flickering display.

User Interface / Display Board Communication Fault

E8

Refrigerator displays E8; compressor does not start or starts briefly then stops; interior may be warm.

Compressor Start / Inverter Module Fault

E9

E9 error displayed; ice build-up on evaporator; fan noise may increase or airflow is weak.

Defrost Sensor or Heater Overheat / Short Fault

Symptom

Alarm beeping and door-open indicator active even when doors are fully closed.

False Door-Open Detection

Symptom

Clicking sound every few minutes; compressor attempts to start but immediately stops; interior warms up.

Compressor Locked Rotor or Start Device Failure

Symptom

Condensation or water droplets forming on the exterior cabinet or around door seals.

Condensation Control / Mullion Heater Issue

Symptom

Display panel works but buttons are unresponsive or respond intermittently.

User Interface Keypad Failure

Symptom

Excessive frost or ice build-up in freezer; drawers difficult to open; frost on door gasket.

Air Ingress / Defrost System Inefficiency

Symptom

Freezer not freezing properly; ice cream soft; refrigerator compartment may still be cool.

Partial Refrigerant Loss or Restricted Capillary Tube

Symptom

High-pitched squealing or chirping noise from inside the freezer compartment.

Evaporator Fan Motor Bearing Wear

Symptom

Ice maker overflows or produces large clumps of ice; ice bin frozen together.

Ice Maker Overfill / Fill Valve Leakage

Symptom

Interior light works but compressor and fans do not run; display may show normal temperatures.

Compressor Control Failure

Symptom

Persistent bad odor inside refrigerator even after basic cleaning.

Odor Contamination / Drain and Air Channel Biofilm

Symptom

Refrigerator door does not close properly or pops open; warm air enters and condensation forms.

Door Alignment / Hinge Sagging

Symptom

Refrigerator interior light stays on when door is closed, causing heat and possible melting near light cover.

Stuck Door Switch or Control Logic Fault

Symptom

Refrigerator not cooling in fresh-food compartment but freezer seems cold; no error code displayed.

Air Duct or Damper Blockage

Symptom

Refrigerator not running at all; display off; interior lights off; no sounds.

No Power / Main Supply Failure

Symptom

Refrigerator runs constantly and never cycles off; temperatures may be normal or slightly low.

Thermostat / Temperature Control Miscalibration or Sensor Drift

Symptom

Unusual loud humming, buzzing, or rattling noise from the refrigerator.

Mechanical Vibration or Fan Noise

Symptom

Water dispenser not working but ice maker still produces ice.

Dispenser Line Freeze or Dispenser Switch Fault

Symptom

Water leaking inside refrigerator compartment, often under drawers or from rear wall.

Blocked Defrost Drain

Symptom

Water leaking onto the floor from under the refrigerator.

Drain Pan Overflow or External Leak
