Bosch Dishwasher Error Code d:11

Error code d:11 on a Bosch dishwasher means the motor control module has detected a voltage level that is too low for proper motor operation. The dishwasher stops running to protect the motor from damage. The fault points directly to the motor control board as the primary suspect, and Bosch diagnostic test P:04 is used to confirm the failure before replacing the board.

No, you should not continue operating the dishwasher while d:11 is active. The error indicates the motor control circuit cannot sustain adequate voltage, which can lead to motor overheating or further damage to the control board. The dishwasher will typically halt operation on its own when this fault is present.

A reset may temporarily clear the d:11 code from the display, but the error will return if the underlying cause has not been repaired. Because this fault is tied to a hardware condition in the motor control circuit, a reset does not fix the problem. Running diagnostic test P:04 is the proper way to evaluate the fault before attempting any repair.

A knowledgeable DIYer can start by checking the incoming line voltage at the terminal block and inspecting wiring harness connectors for corrosion or loose terminals, as these require no parts. However, running the P:04 diagnostic test and replacing the motor control board if it fails typically requires familiarity with appliance disassembly and electrical components. If you are not comfortable working with line voltage, a qualified technician should handle this repair.

If the motor control board needs replacement, parts alone typically range from $80 to $250 depending on the specific Bosch model. Adding professional labor, the total repair cost generally falls between $150 and $400. If the cause turns out to be a loose wiring connection or low supply voltage rather than a faulty board, the cost can be significantly lower.
