VERIFIED
Er indicates a probe/sensor error or defective probe on older controllers on the platforms that document this token.
Owners seeing Er note the display and measure the affected zone separately.
Seal contact is verified first when Er appears on the panel.
One power cycle is tried if Er may be transient.
Ongoing Er with poor temperatures leads to testing the documented part.
Model confirmation precedes lookup of the platform procedure. This applies to Er.
Controller response for the indicator is checked against series notes. This applies to Er.
Sensor testing for the token follows after basic checks. This applies to Er.

Frequently asked questions
No. Documentation shows platform and model differences.
Check measured temperatures. Move food if readings are unsafe.
A single power cycle is safe to try. Record whether the code returns.
Model compatibility: Liebherr reuses codes across series and model years, so Er may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
