E05

Hansa oven displays E05 and the cooling fan runs continuously or not at all; oven may shut down during use.

Cooling Fan or Fan Sensor Fault

E06

Hansa oven shows E06 and the convection fan does not run in fan-assisted modes; uneven baking results.

Convection Fan Motor Fault

E07

Hansa oven display shows E07 and the door lock engages or remains locked even when the oven is cool.

Door Lock Mechanism / Switch Fault

E08

Hansa oven shows E08 and the display or touch controls behave erratically or are unresponsive.

User Interface / Touch Panel Communication Error

E09

Hansa oven displays E09 and will not start; often associated with child lock or key symbol issues.

Keypad / Button Stuck or Child Lock Circuit Fault

E10

Hansa oven shows E10 and the interior light does not work; other functions may be normal.

Oven Lamp Circuit Fault

E11

Hansa oven displays E11 and the clock/timer cannot be set or loses time frequently.

Clock / Timer Circuit Fault

E12

Hansa oven shows E12 and shuts down when using pyrolytic self-cleaning (on models with pyrolysis).

Pyrolytic Temperature / Safety Circuit Fault

E13

Hansa oven displays E13 and the door will not unlock after a self-clean or high-temperature cycle.

Door Lock Overheat / Position Error

E14

Hansa oven shows E14 and some heating modes (e.g., grill or bottom heat) do not work.

Secondary Heating Element Circuit Fault

E15

Hansa oven displays E15 and trips the household circuit breaker when a heating mode is selected.

Earth Leakage / Short to Ground

E16

Hansa oven shows E16 and the internal cooling fan runs at maximum speed or not at all, with noisy operation.

Cooling Fan Speed / Tachometer Fault (on variable-speed models)

E17

Hansa oven displays E17 and the cavity temperature does not match the set temperature; food undercooks or overcooks.

Temperature Calibration / Sensor Range Error

E18

Hansa oven shows E18 and the display backlight or indicators flicker or go dark intermittently.

Low-Voltage Power Supply Fault

E19

Hansa oven displays E19 and the gas burner (on gas or gas-electric models) does not ignite or goes out.

Gas Ignition / Flame Detection Fault

E20

Hansa oven shows E20 and the fan-assisted gas burner (if equipped) fails to operate correctly.

Gas-Fan Interlock / Safety Fault

Symptom

Hansa oven bottom heat function does not work; top and grill heat normally.

Bottom Heating Element Failure

Symptom

Hansa oven buttons or touch controls do not respond, or respond intermittently.

User Interface Failure or Contamination

Symptom

Hansa oven clock and settings reset every time power is turned off or after brief outages.

Non-Volatile Memory or Backup Power Failure

Symptom

Hansa oven cooling fan runs continuously long after cooking has finished, or never runs at all.

Cooling Fan Control or Thermostat Fault

Symptom

Hansa oven display is blank or very dim, but the oven may still heat when knobs are turned (on some models).

Display / Power Supply Failure

Symptom

Hansa oven does not heat at all; display and lights work but no warmth in any mode and no error code is shown.

Main Power Supply to Heating Circuit Failure

Symptom

Hansa oven door does not close fully or seals poorly, causing heat to escape and uneven cooking.

Door Hinge or Seal Deformation

Symptom

Hansa oven door glass is cracked, shattered, or loose.

Door Glass Assembly Damage

Symptom

Hansa oven emits a metallic or electrical buzzing noise when heating.

Vibrating Panel, Transformer Hum, or Arcing

Symptom

Hansa oven emits a strong burning smell or smoke during normal cooking (not first use).

Grease or Food Residue Burning / Insulation Contamination

Symptom

Hansa oven fan is very noisy, rattling, or scraping during operation.

Convection Fan Bearing Wear or Obstruction

Symptom

Hansa oven fan runs but there is no heat in fan-assisted modes; conventional modes may still work.

Convection (Ring) Element Failure

Symptom

Hansa oven grill function does not work, but other heating modes are normal.

Grill Element or Circuit Failure

Symptom

Hansa oven heats but takes a very long time to reach temperature; baking times are much longer than normal.

Partial Heating Element Failure or Low Voltage Supply

Symptom

Hansa oven interior light and fan work, but elements cycle on and off very rapidly, causing unstable temperature.

Control Relay Chatter or Poor Power Supply

Symptom

Hansa oven interior light does not work, but heating and other functions are normal.
