Electrolux Oven Error Code CE1

The CE1 error code on an Electrolux oven indicates a wrong parameter configuration, specifically a conflict in the appliance's control system settings. The error is triggered when the oven is configured as a unit equipped with a boiler (parameter 24:APPL set to 0) but the lambda probe parameter (6:LAMb) is also set to 0, meaning no lambda probe is registered in the system. These two settings are mutually exclusive in proper configurations: a boiler-equipped appliance requires a lambda probe to regulate combustion air-to-fuel ratios, so having both set to absent or inactive creates an invalid operational state that the control board cannot resolve.

The lambda probe is a sensor that monitors oxygen levels in combustion exhaust gases to ensure efficient and safe burner operation. When the control system detects that a boiler configuration is active but no lambda probe is assigned or recognized, it halts machine operation entirely as a safety and functional precaution. This is a firmware-level parameter mismatch, not a mechanical failure in the traditional sense. The error is generated during the system's self-check of its own configuration registers, and the oven will not proceed to normal operation until the conflict is resolved.

This type of error most commonly results from an incorrect parameter setup following a control board replacement, a firmware update that reset configuration values, or an accidental modification to the appliance's parameter settings. It can also occur if the control board was sourced for a different appliance variant and programmed with mismatched settings. Resolving CE1 requires accessing the service parameter menu and correcting either the appliance type parameter (24:APPL) or the lambda probe parameter (6:LAMb) to create a consistent, valid configuration.
