Bosch Dishwasher Error Code dr:11

The dr:11 code means the dishwasher has detected that its incoming supply voltage is too low for safe operation. The control board monitors electrical input continuously and triggers this fault when voltage falls below the acceptable threshold. The appliance shuts down the cycle as a protective measure. The issue can stem from the home's electrical supply or, less commonly, from internal wiring or board problems.

A reset may temporarily clear the code, but the error will return if the underlying voltage problem has not been corrected. To reset, turn off power to the dishwasher at the breaker for about one minute, then restore power. If dr:11 reappears immediately or during the next cycle, the root cause must be diagnosed and repaired.

If the problem is limited to a loose connection or a circuit issue, the repair cost can be minimal, covering only an electrician's service call in the range of $75 to $150. If a power cord or wiring harness needs replacement, parts and labor typically range from $100 to $250. A control board replacement is the most expensive scenario, with parts and labor often ranging from $200 to $400 or more depending on the model.

Start by checking the voltage at the outlet or hardwire connection using a multimeter to confirm the supply is adequate. Inspect all wiring connections at the outlet, junction box, and breaker for looseness or corrosion. If the supply voltage is normal and connections are secure, check the power cord and internal wiring harness for damage before considering a control board replacement.

You should not attempt to run the dishwasher while this error is present. Low voltage conditions can cause motors and electronic components to draw excessive current in an attempt to compensate, which can lead to overheating or permanent damage. Address the power supply issue before resuming normal operation.
