Bosch Washer Error Code 44

Error code 44 on a Bosch washer means the control board's self-test of the relay circuit used to reverse the drum motor's direction has failed, and the triac responsible for this switching function is identified as broken. The triac is a semiconductor component built into the main control board. This fault prevents the washer from operating because the drum cannot safely alternate rotation directions during a wash cycle.

Resetting the error through the test mode is the recommended first diagnostic step and may clear a fault caused by a transient power surge. However, if the triac on the control board is genuinely broken, the error code 44 will return as soon as the board runs its relay self-test again. A persistent error after reset confirms a hardware failure that requires parts replacement.

If a control board replacement is needed, parts alone typically range from $150 to $400 depending on the specific model, with professional labor adding another $100 to $200. Board reconditioning services, if available for the specific board, may cost less. If the error was caused by a transient fault and clears after a test mode reset with no return, there may be no parts cost at all.

The first step is to reset the error by activating the washer's test mode and observing if the fault returns. If it reappears, the repair requires inspecting or replacing the main control board, as the triac is an internal board component. Technicians comfortable with electronics may be able to have the board repaired or reconditioned, but most DIYers will find full board replacement the more practical option.

No. Error code 44 indicates the drum motor's direction-change relay circuit has failed, and the washer will not complete a normal cycle without proper bidirectional motor control. Running the machine in this condition risks incomplete washing, potential motor stress, and additional electrical component damage. The washer should not be operated until the control board issue is resolved.
