Whirlpool Microwave Error Code ERR 6

ERR 6 means the weight sensor calibration was not performed correctly. The weight sensor is used for automatic cooking functions that calculate cook time and power based on food weight. The error appears when the control board cannot confirm a valid calibration baseline. Running the calibration procedure again is the recommended first step.

A simple power reset is unlikely to permanently clear ERR 6 because the error is tied to the calibration status stored in the control board. The error will typically return after the reset if calibration has not been properly completed. The correct resolution is to run the full calibration sequence successfully.

If the error is resolved by recalibration alone, there is no parts cost and any service call would be limited to a standard diagnostic or labor fee, typically in the range of $50 to $100. If the weight sensor itself needs replacement, parts and labor together could range from $75 to $200 or more depending on the model and service provider. Attempting the calibration yourself first is always the most cost-effective starting point.

The fix is to perform the calibration procedure as outlined in the calibration section of your unit's documentation. Make sure the microwave is on a flat, stable surface and that nothing is placed inside the cavity during the process. Complete the sequence without interruption. If the error returns after multiple correct attempts, inspect the weight sensor and its wiring connections for faults.

ERR 6 relates to the weight sensor calibration and does not indicate an electrical hazard. However, automatic cooking functions that rely on food weight will not operate accurately without a valid calibration. Basic manual cooking functions may still work, but it is best to complete the calibration before relying on the microwave for automatic or sensor-based cooking modes.
