Dometic Wine Coolers Error Codes

dF

Display shows "dF" or similar; unit may pause cooling periodically.

Defrost Mode Indication (Not a Fault) / Defrost Cycle Active

E1

Wine cooler beeps and displays E1, unit may stop cooling or run continuously.

Cabinet Temperature Sensor Failure

E10

Wine cooler displays E10 and may not maintain set temperature; dual-zone models may have one zone disabled.

Dual-Zone Communication or Zone Control Fault

E2

Wine cooler displays E2 and may not regulate temperature correctly; compressor or fans may cycle abnormally.

Evaporator / Return Air Temperature Sensor Failure

E3

Wine cooler shows E3 and may not cool or may overcool; temperature display may be inaccurate.

Ambient / Room Temperature Sensor Failure

E4

Wine cooler displays E4 and may shut down cooling or run continuously; defrost may not operate correctly on compressor models.

Defrost Sensor or Defrost Circuit Fault

E5

Wine cooler shows E5 and may not cool; compressor or Peltier module may not start.

Compressor / Cooling Module Drive Fault

E6

Wine cooler displays E6 and may not respond to temperature changes; buttons may still work but cooling is erratic.

Communication Error Between Display PCB and Main Control PCB

E7

Wine cooler shows E7 and interior light or fan may not operate correctly; sometimes cooling is disabled.

Door Switch or Door Sensor Fault

E8

Wine cooler displays E8 and may shut down or limit cooling; fans may stop.

High Temperature or Overheat Protection Fault

E9

Wine cooler shows E9 and interior fan may not run; temperature may be uneven inside cabinet.

Evaporator / Internal Circulation Fan Fault

Er

Display shows "Er" or generic error; unit may beep and stop responding to some controls.

General Control Board or Display Error

F1

Wine cooler beeps and shows F1; cooling may be disabled until error is cleared.

Upper Zone Temperature Sensor Fault (Dual-Zone Models)

F2

Wine cooler shows F2; lower zone may not cool or may run erratically.

Lower Zone Temperature Sensor Fault (Dual-Zone Models)

F3

Wine cooler displays F3 and may not defrost properly; ice buildup may occur.

Defrost Sensor / Evaporator Sensor Error (Alternate Code)

F4

Wine cooler shows F4; interior fan may not run or may run continuously.

Fan Speed / Fan Feedback Error

F5

Wine cooler displays F5; compressor may short-cycle or fail to start.

Compressor Overload or Current Fault

Hi

Display shows "Hi" or flashes at highest temperature; unit may not cool or may shut down cooling.

Temperature Above Display Range / High Temperature Alarm

Lo

Display shows "Lo" or flashes at lowest temperature setting; unit may run continuously and risk over-chilling bottles.

Temperature Below Display Range / Sensor Misread

Symptom

Clicking sound from the rear of the wine cooler; compressor tries to start but shuts off repeatedly.

Compressor Short Cycling / Start Failure

Symptom

Condensation or fogging on the glass door, especially in humid environments.

Door Condensation / Insulation Issue

Symptom

Excessive frost or ice buildup on the evaporator or interior walls of the wine cooler.

Frost Buildup / Defrost System Failure

Symptom

Interior fan is noisy or does not run, causing uneven temperatures inside the cabinet.

Evaporator / Circulation Fan Failure

Symptom

Interior light stays on even when the door is closed, causing warming inside the cabinet.

Light Stuck On / Door Switch Fault

Symptom

Interior temperature fluctuates widely; bottles experience frequent warming and cooling cycles.

Temperature Control Instability

Symptom

Set temperature changes by itself or buttons do not respond properly.

Keypad / Control Panel Malfunction

Symptom

Shelves are difficult to slide or do not sit level, risking bottle breakage.

Shelf Support / Rail Issue

Symptom

Temperature between upper and lower zones is not separated; both zones show similar temperatures despite different setpoints.

Dual-Zone Separation Failure

Symptom

Water pooling at the bottom of the wine cooler or leaking onto the floor.

Drainage / Condensate Leak

Symptom

Wine cooler beeps continuously or intermittently without any visible error code.

Alarm Circuit Activation Without Display Code

Symptom

Wine cooler display is blank or very dim; unit may still cool or may be completely dead.

Display Power / Display PCB Failure

Symptom

Wine cooler does not power on at all; no lights, no display, no sound.

No Power / Dead Appliance

Symptom

Wine cooler door will not close properly or pops open slightly after closing.

Door Alignment / Hinge or Gasket Issue

Symptom

Wine cooler emits a strong chemical, plastic, or burning smell during operation.

Odor / Overheating Component

Symptom

Wine cooler interior light does not turn on when door is opened, but cooling works normally.

Interior Light Failure

Symptom

Wine cooler makes loud humming, rattling, or vibrating noises during operation.

Excessive Noise / Vibration

Symptom

Wine cooler not cooling at all; interior light works but no cold air, compressor or Peltier module silent.

No Cooling / Cooling System Not Starting

Symptom

Wine cooler runs but does not get cold enough; temperature stays above setpoint in all zones.

Insufficient Cooling / Loss of Capacity

Symptom

Wine cooler runs continuously and overcools; bottles may be too cold or partially frozen.

Runs Constantly / Overcooling

Symptom

Wine cooler trips the household circuit breaker or RCD when plugged in or shortly after starting.

Electrical Short / Ground Fault
