Bosch Dishwasher Error Code LOWPOWER

The LOWPOWER code means the dishwasher has detected that the incoming mains voltage has dropped below its minimum safe operating level. For US models the minimum is 85V, and for EU and Australian models it is 165V. The dishwasher shuts down automatically to protect its internal components from damage caused by running under insufficient voltage. The issue typically originates in the home's electrical supply rather than the dishwasher itself.

Resetting the dishwasher will clear the displayed error code temporarily, but the code will return if the underlying low-voltage condition has not been corrected. The dishwasher's control board checks incoming voltage at startup and during operation, so it will detect and report the fault again as soon as it measures voltage below the minimum limit. Always resolve the voltage issue before assuming a reset has fixed the problem.

If the problem is a utility brownout or a simple loose connection, the fix may cost little to nothing beyond a service call fee, typically in the range of $75 to $150. If the circuit wiring or breaker needs to be replaced by a licensed electrician, costs generally range from $150 to $400 or more depending on the extent of the work. In the less common scenario where the dishwasher's internal control board has been damaged by sustained low voltage, board replacement parts and labor can range from $200 to $500.

Start by measuring the actual mains voltage at the outlet or terminal supplying the dishwasher using a multimeter. If voltage is below the minimum threshold, check for other heavily loaded appliances on the same circuit, inspect all wiring connections for looseness or corrosion, and contact a licensed electrician if the problem points to your home's wiring or circuit breaker. If voltage at the supply point is normal, the issue may be in the connection between the outlet and the dishwasher.

No, you should not attempt to run the dishwasher while this error is active. Operating the appliance under low-voltage conditions can cause the motor, heating element, and control board to draw excessive current, leading to overheating and component damage. The dishwasher's protective shutdown is designed to prevent this, and bypassing or ignoring it risks costly repairs or creating a fire hazard in the wiring.
