Condensation / Ventilation Issue
Symptom
Oven clock and settings reset every time power is switched off, or time cannot be set correctly.
Clock / Memory Retention Issue
Symptom
Oven display and controls work, but when a program is started nothing happens (no fan, no heat, no click).
Main Relay / Safety Chain Not Energizing
Symptom
Oven does not heat at all in any mode, no error code displayed, fan and light may still work.
Open Heating Circuit / Supply to Elements Lost
Symptom
Oven door does not seal properly; heat escapes around the edges, and front panel gets very hot.

Symptom
Oven door glass is cracked, shattered, or loose, but oven otherwise works.
Door Glass Panel Damage
Symptom
Oven door will not close fully or sits crooked, causing heat loss and poor cooking.

Worn or Contaminated Function Selector Switch
Symptom
Oven trips the household circuit breaker or RCD as soon as it is turned on or when heating starts.
Short Circuit / Earth Leakage in Heating Circuit
Symptom
Oven trips the RCD (residual current device) only when a specific function (e.g. grill) is used.
Function‑Specific Earth Leakage
Symptom
Pyrolytic self‑cleaning does not start; door remains unlocked and program aborts.
