Whirlpool Dryer Error Code E:23

E:23 indicates a Variant to Table Set Mismatch inside the dryer's electronic control board. The control contains a variant identifier that does not correspond to a valid table set in its memory, which means the board's internal configuration data is invalid or corrupted. This is a firmware-level fault, not a sensor or mechanical failure.

No. A power cycle or reset will not clear E:23 because the fault is caused by an internal configuration conflict within the control board itself. The mismatch exists in the board's permanent memory, so it will return every time the control powers up. Replacement of the control board is the only resolution.

The primary cost is the replacement control board, which typically ranges from $80 to $250 depending on the specific dryer model. If you hire a technician, labor costs generally add another $80 to $150 to the total repair bill. Sourcing the correct part number for your exact model is important to avoid repeating the mismatch issue.

The fix requires replacing the electronic control board, which is a task many experienced DIYers can handle. You will need to locate the correct replacement control for your specific dryer model, disconnect power, and swap the board following proper precautions. There is no software reset or adjustment that resolves this error.

The dryer should not be relied upon for normal use while displaying E:23. Because the control board's configuration data is invalid, the dryer may not operate its components correctly, including heating circuits and safety shutoffs. Discontinue use until the control board has been replaced.
