Bosch Dishwasher Error Code E:17

E:17 on a Bosch dishwasher means the control board has detected a fault in the drain pump circuit. The wash cycle stops abruptly, the drain pump runs continuously, and the Sanitized LED flashes to indicate the error. The cause is typically a faulty drain pump wiring harness or a failed drain pump motor. Diagnosis involves checking harness continuity and measuring the drain pump's resistance, which should read approximately 80.5 ohms at room temperature.

You should not attempt to run the dishwasher while the E:17 error is active. The appliance is already stopping the wash cycle as a protective response, and continued use could cause water overflow or further damage to the drain pump or control board. Resolve the fault before running another wash cycle.

A reset may temporarily clear the error code and allow the dishwasher to start a cycle, but if the underlying component fault is still present, E:17 will return. Resetting does not repair a failed drain pump or a damaged wiring harness. The error will continue to recur until the faulty component is identified and replaced.

A knowledgeable DIYer can perform the initial diagnostics, including visually inspecting the drain pump connector and checking harness continuity with a multimeter. Measuring pump resistance at the terminals to compare against the 80.5-ohm specification is also within reach for someone comfortable with basic electrical testing. However, replacing the drain pump or wiring harness requires disassembling portions of the dishwasher, and comfort with appliance repair work is recommended before attempting those steps.

Repair costs depend on which component has failed. A replacement drain pump for a Bosch dishwasher typically costs in the range of $50 to $150 for the part alone, while a wiring harness is generally less expensive. If you hire a technician, labor charges will add to that total, often bringing the complete repair cost to somewhere between $150 and $350 depending on your location and the specific model.
