Bosch Dishwasher Error Code E:9010

E:9010 is an over-voltage error indicating the dishwasher detected incoming line voltage exceeding 142 volts AC. To protect its internal components, the appliance shuts itself off automatically. The fault lies in the external power supply, not inside the dishwasher itself. Checking and correcting the supply voltage is the required first step.

No, you should not operate the dishwasher while E:9010 is active. The error indicates the power supply voltage is dangerously elevated, and running the appliance under these conditions risks permanent damage to the control board, motor, and other electrical components. The dishwasher's automatic shutoff is a safety feature, and the underlying voltage issue should be resolved before restarting the machine.

Because E:9010 is a power supply issue rather than an appliance fault, repair costs depend on what is wrong with the electrical system. A basic electrician service call typically ranges from $75 to $200, while panel repairs or outlet rewiring can range from $150 to $600 or more depending on the scope of work. If over-voltage has already damaged internal dishwasher components, additional appliance repair costs would apply on top of the electrical work.

Start by measuring the voltage at the outlet serving the dishwasher using a multimeter or plug-in voltage monitor. If the voltage reads above 125V or is fluctuating significantly, contact your utility provider and a licensed electrician. Do not attempt to use the dishwasher until the supply voltage is confirmed to be within normal range, as continued over-voltage exposure can damage internal components.

Resetting the dishwasher by powering it off and back on may temporarily clear the error display, but the code will return if the supply voltage is still above 142V. A reset does not address the root cause. The error will only stop recurring once the incoming power supply is corrected and stays within the acceptable voltage range.
