Whirlpool Washer Error Code CA

The CA code stands for average current limit trip. It means the washer's motor controller detected a two-second average of current draw greater than 5.55 amps at the motor windings. The machine shuts down automatically to prevent damage to the motor and control circuitry. The error points to an overloaded drum, a failing drive motor, a bad motor control board, or a mechanical resistance issue.

You should not continue running the washer while the CA error is active. The code indicates the motor is drawing dangerously high current, and continued operation risks overheating the motor, damaging the motor control board, or causing a more serious electrical fault. The machine is designed to stop automatically for this reason, and you should diagnose the cause before running another cycle.

Start by ruling out overloading and mechanical drag: remove the load, spin the drum by hand, and check for unusual resistance or noise from bearings and drive components. If the drum spins freely and the error persists with a normal load, use a multimeter to test the drive motor winding resistance and verify the thermal protector is not open. If the motor tests within specification but the error continues, the motor control board is the next likely suspect and should be inspected for burned components or tested by substitution.

Pressing STOP/CANCEL will clear the CA code from the display, but it does not fix the underlying problem. If the cause is simply an overloaded drum, reducing the load before restarting may resolve it permanently. If the error returns during normal operation with a reasonable load, a component such as the drive motor or motor control board needs to be diagnosed and likely replaced.

Repair costs depend entirely on what is causing the fault. If the fix is as simple as adjusting the load size, there is no cost. A replacement drive motor typically runs in the range of $150 to $350 for the part alone, while a motor control board can range from $100 to $300 or more. Adding professional labor will increase total costs by $100 to $200 depending on your area.
