Complete Guide to SMEG Cooker, Oven and Induction Hob Error Codes
If your SMEG appliance is showing an error code, this guide will help you understand what the fault may mean and what basic checks you can carry out before arranging a professional appliance inspection in London.
SMEG appliances are known for their distinctive design, premium build quality and reliable performance. However, like any electrical appliance, errors can sometimes appear on SMEG ovens, cookers, induction hobs and other appliances. Understanding SMEG error codes can help you identify whether the issue is linked to the power supply, sensor, fan, heating element, control board or internal communication system.
Common SMEG Induction Hob Error Codes
Error E6 — Power Supply or Main Board Fault
Meaning: A fault has been detected in the hob’s power supply or main control board.
Basic check: Switch the hob off at the mains for a few minutes. If the error continues, the main board or power supply section should be inspected by a technician.
Error E8 — Cooling Fan Fault
Meaning: The internal cooling fan may be spinning too fast or too slowly, or the fan sensor may be faulty.
Basic check: Make sure the air vents are not blocked. If the fault remains, the fan or its sensor may need to be checked.
Error E9 — Induction Temperature Sensor Fault
Meaning: The induction coil temperature sensor is not working correctly or is not reporting the temperature properly.
Basic check: Switch the hob off for a few minutes to reset it. If the error appears again, the temperature sensor should be inspected.
Error Er03 — Touch Control Panel Fault
Meaning: A touch button may be stuck, or moisture and dirt may have been detected on the control panel.
Basic check: Clean and dry the control panel thoroughly, then switch the appliance off for a few minutes and restart it.
Important Safety Note
Before carrying out any checks, disconnect the appliance from the power supply. SMEG induction hobs, ovens and cookers are high-powered electrical appliances, and opening internal components without technical knowledge can be dangerous.
Common SMEG Oven Error Codes
Error E2 — Over Temperature or Thermostat Fault
Meaning: The oven temperature has exceeded a safe level, or the thermostat may be faulty. Switch the oven off and allow it to cool completely. If the error returns, the thermostat and temperature sensor should be inspected.
Error E5 — Oven Temperature Sensor Fault
Meaning: The oven temperature sensor may be disconnected, damaged or giving abnormal readings. In this situation, the oven temperature may not be controlled accurately and professional inspection may be needed.
Error E6 — Board or Power Module Fault
Meaning: The main control board or power module has detected a fault. Switch the appliance off for a few minutes. If the fault remains, the board should be checked.
Error E7 — Heating Element Fault
Meaning: One or more oven heating elements may not be working correctly. If the oven is not heating or heat is uneven, the heating element and wiring should be checked.
Error E8 — Fan or Cooling Fault
Meaning: The internal oven fan may not be working correctly, or its speed may be abnormal. The vents and airflow path should be checked.
Error F5 — Door Lock or Pyrolytic Lock Fault
Meaning: The door lock mechanism or its sensor may be stuck, often during a pyrolytic cleaning cycle. Do not force the door open and keep the appliance switched off until it can be inspected.
SMEG Communication and Internal Control Faults
Error Er20 — Communication Fault
Meaning: Communication between the control board and the user interface module has been interrupted. Switch the appliance off and back on. If the error continues, professional inspection is recommended.
Error Er22 — Internal Sensor or Thermal Fuse Fault
Meaning: An internal sensor may not be responding correctly, or the overheat protection may have been triggered. The sensor, thermal fuse and board should be inspected.
Error Er31 — Internal Communication Error
Meaning: The internal electronic system has lost communication with one of its modules. Disconnect the appliance from the power supply for a few minutes, then restart it.
Error U400 — Incorrect Power Supply
Meaning: Incorrect voltage or mains phase has been detected. This should be checked by a qualified electrician.
SMEG Range Cooker Error Codes: Oven and Induction Hob Combined
In SMEG range cooker models where the oven and induction hob are combined in one appliance, some faults may affect both sections. Errors such as E6, E8, E9, F3 and ER03 may be linked to the main board, cooling fan, induction hob sensor, oven heating element or touch control panel.
If these errors continue after resetting the appliance, it is better to avoid further use to help prevent additional damage.
When Should You Arrange a SMEG Appliance Inspection?
If your SMEG appliance continues to display an error code after resetting, the oven is not heating properly, the induction hob will not switch on, the fan is making unusual noises, the oven door remains locked, or the touch panel is not responding correctly, it is best to have the appliance checked by a qualified technician.
For London homes, a prompt and proper SMEG appliance inspection can help identify the exact cause of the fault and prevent further appliance issues. Opening internal components without technical knowledge is not recommended.
