A Weight Guard calibration error code is generated when the system degradation is severe. These codes indicate to the user to examine the system/clean the platter. Re-calibration can be performed if the error persists after system cleaning.
The system LED also blinks red to indicate the severity of the condition. The following warning codes are generated on the 7-segment display depending on which Weight Guard shows the error condition. The off-platter detection feature is disabled while in this state.
