Touch Control Panel Failure
E12
Clock cannot be set or resets randomly; oven functions are disabled until the time is set.
Electronic Timer / Clock Module Fault
E13
Oven trips the circuit breaker or RCD when heating starts.
Earth Leakage / Short Circuit in Heating System
E14
Oven interior light and display work, but selecting any function causes an immediate error and no operation.
Door Switch / Door Closed Detection Fault
E15
Steam-assisted or steam-clean function not working, or an error is displayed when steam mode is selected.
Steam Generator / Water System Fault
E16
Cooling fan runs, but the oven remains locked, and the error persists after a pyrolytic cycle.
Pyrolytic Cycle Overheat / Lockout Fault
E17
Display is very dim or flickering; an error is sometimes logged on the power supply.
Low Voltage / Power Supply Fault
E18
Child lock symbol displayed, oven controls locked, sometimes misinterpreted as an error.
Child Lock / Key Lock Activated
E19
Oven fan runs, but the temperature display does not increase; an error related to sensor calibration may appear on some models.
Temperature Calibration / Sensor Drift
E20
Oven display shows a generic fault code, no specific function is indicated, and the oven is disabled.
General Control Board Fault
Symptom
Buttons or touch keys work intermittently, requiring very hard presses.
Worn Keypad / Touch Sensitivity Issue
Symptom
Display segments are missing or unreadable, but the oven still heats.
Display Module Degradation
Symptom
Excessive condensation on the oven door and control panel during cooking.
Poor Ventilation / Steam Management
Symptom
High-pitched whining or humming noise from the top of the oven during operation.
Cooling Fan or Transformer Noise
Symptom
Loud rattling or scraping noise from the rear of the oven when the fan is running.
Convection Fan Mechanical Noise
Symptom
Oven cooks unevenly, hotter at the back or one side, with food burnt on top and raw underneath.
Uneven Heat Distribution
Symptom
Oven door glass is loose, rattling, or has condensation between the panes.
Door Glass Assembly / Seal Failure
Symptom
Oven door will not close fully, heat escaping around the door, and no error code is displayed.
Door Misalignment / Hinge Wear
Symptom
Oven heats but takes a very long time to reach temperature, resulting in uneven cooking.
Reduced Heating Performance
Symptom
Oven interior enamel is chipped, or rust spots are appearing.
Cavity Coating Damage
Symptom
Oven light works, but the display and controls are completely dead.
Control Circuit Power Loss
Symptom
Oven not heating at all, no error code displayed; the fan and light may still work.
Complete Heating Loss Without Error
Symptom
Oven racks or telescopic runners are difficult to slide, squeaking, or sticking.
Rack / Runner Wear or Contamination
Symptom
Oven trips RCD or circuit breaker as soon as the door is opened or closed.
Door-Activated Circuit Short
Symptom
Strong burning smell or smoke from the oven during normal cooking (not during first use or pyrolytic cleaning).
Overheating / Component Burn-Off
Symptom
The oven timer counts down, but heating stops before the set time is reached.
Premature Cycle Termination
Symptom
The oven will not start; the display shows the time, but there is no response when selecting functions (no error code).
User Interface Logic Lock / Misconfiguration
Symptom
The oven's exterior sides and control panel become excessively hot during use.
Cooling / Insulation Deficiency
