Continental Washer Error Code A-12

The A-12 code indicates that the motor's thermal protection device, called a klixon, has opened due to excessive motor temperature. This opens the circuit between the CM and X1 terminals at the inverter, which simultaneously displays an OH2 fault. The machine shuts down automatically to prevent damage to the drive motor. The most frequent trigger is a drain system that is too slow to evacuate water within the normal timeframe.

No, you should not continue operating the washer while the A-12 fault is active. The code means the motor has already reached an unsafe temperature, and continuing to run it risks permanent motor damage. Allow the machine to cool completely before attempting to diagnose and resolve the underlying cause.

Repair costs vary widely depending on the cause. If the issue is simply a clogged drain filter or kinked drain hose, the repair may cost very little. If the drain pump needs replacement, expect to pay somewhere in the range of $150 to $350 including labor. Motor or bearing replacement is more involved and could run from $300 to $600 or more depending on the model and local labor rates.

Start by checking that the washer drains completely and within the expected time, which is 15 to 20 seconds for machines up to 50 lb and 30 to 40 seconds for larger models. Clear any blockages in the drain hose, pump filter, or drain pump. Allow the motor to cool fully before restarting, and avoid overloading the drum. If the error returns after addressing drain performance, have the motor, bearings, and klixon switch inspected by a qualified technician.

A reset may temporarily clear the fault, but only after the motor has cooled enough for the klixon to close again. If the root cause, such as a slow drain, overloaded drum, or worn bearings, is not corrected, the motor will overheat again and the A-12 error will return. Resetting without fixing the underlying problem is not a lasting solution.
