How to Reset a Dishwasher Control Board: Safe Steps
Short answer: If your dishwasher's control board is unresponsive or shows an error, start by unplugging the unit for a few minutes or tripping the circuit breaker. Restoring power after that clears many temporary faults. If the problem persists, consult the owner's manual for a deeper reset, such as a specific button sequence or service mode. Never open the control board unless you are qualified.
Why a dishwasher control board needs a reset
Dishwasher control boards manage every cycle, from filling and washing to draining and drying. They rely on electronic memory to store settings and error codes. Like any computer, they can occasionally freeze or lock up after a power surge, a spike in the water heater, or a glitch in the sensor system. When that happens, the dishwasher may refuse to start, stop mid-cycle, or display an error code that is not related to a real mechanical problem.
Most of these faults are not permanent. A simple power cycle, which cuts and restores electricity to the control board, is the first step recommended by many manufacturers. It clears the volatile memory and forces the board to reboot, much like restarting a computer. For more on how control panels differ, see our guide to dishwasher control panel types.
The safe power cycle: unplug or trip the breaker
Begin by unplugging the dishwasher from the wall outlet. If the unit is hardwired, which is common for built-in models, switch off the dedicated circuit breaker at the electrical panel. This is the safest way to ensure the control board is completely without power. Do not attempt to unplug a unit that is still running; always cancel the cycle and wait for it to finish or pause before cutting power.
Leave the power off for at least a few minutes. This gives the capacitors inside the power supply time to discharge and ensures the memory is cleared. A few minutes is usually enough, though some service guides suggest a longer wait. After the wait, restore power and observe the display. If the error code reappears immediately, the fault is persistent and may require a deeper reset. For wiring details, see dishwasher electrical connection.
What to do after power is restored
After restoring power, wait for the control board to boot up. This may take a few seconds. If the dishwasher has a display, it should light up normally. Run a quick cycle, such as a rinse or short wash, to confirm the unit operates correctly. If the error returns, move on to the next step.
Some dishwashers have a specific reset sequence that you can perform from the control panel. This might involve pressing a combination of buttons, such as holding two keys for a few seconds, or using a service mode entered through a hidden menu. These sequences are not universal, so you need the owner's manual for your model. Manufacturers like Bosch provide downloadable manuals and how-to videos on their support pages. For common error codes, see how to reset dishwasher error codes.
When a deeper reset is needed
A power cycle clears temporary faults, but some errors are stored in non-volatile memory. For those, a deeper reset is required. This might be a factory reset that restores the control board to its out-of-the-box state, erasing custom settings and saved cycles. Factory resets are usually described in the manual under troubleshooting or service modes.
Before attempting a factory reset, check whether your dishwasher has a reset button or a sequence that only involves the existing buttons. Many models use a combination like holding the start button for a few seconds, or pressing a series of cycle buttons in order. If you have a connected dishwasher, some manufacturers, such as Fisher & Paykel with their SmartHQ app, allow you to trigger a reset remotely. Consult the app's support section for instructions. For more on connected features, see dishwasher smart features.
If the reset does not clear the fault
If you have tried both a power cycle and the manufacturer's reset sequence and the error persists, the control board may be damaged or a sensor may be faulty. Look up the specific error code in your manual to understand what component is involved. Common codes point to water inlet issues, heating element faults, or temperature sensor failures.
At this point, you need to decide between repairing and replacing the control board. A new control board can be expensive, and installation requires careful handling of live electrical parts. If your dishwasher is older and still under warranty, contact the manufacturer's support first. If it is out of warranty, you may want to compare the cost of a repair with the price of a new model. See our guide to replacing a dishwasher control panel for steps, and consider our built-in dishwasher buyers checklist if you decide to replace.
Safety precautions before resetting
Always unplug the dishwasher or switch off the breaker before you touch any internal component. If you need to open the control panel, make sure the power is off and the unit is dry. Do not use water near the electrical connections. If you are not comfortable working with electricity, call a professional.
Never press random buttons hoping to clear an error. This can alter settings or enter a test mode that may cause unexpected behavior. Always follow the manual. Some dishwashers have a child lock that can prevent resets; check that feature as well. If your dishwasher trips the GFCI outlet repeatedly, the problem may be in the power supply, not the control board. For more on these topics, see dishwasher child lock and dishwasher trips GFCI outlet.

Questions
How long should I unplug the dishwasher?
Wait at least a few minutes to let the control board's capacitors discharge. Some technicians recommend leaving it off for longer, but a few minutes is usually enough to clear temporary faults.
Will resetting erase my saved cycles and settings?
A simple power cycle usually does not erase saved settings, as they are stored in non-volatile memory. A factory reset, which you may need to perform manually, will erase custom cycles and return the dishwasher to its default configuration.
What if my dishwasher is hardwired and has no plug?
If the dishwasher is hardwired, switch off the dedicated circuit breaker at the electrical panel. This cuts power to the unit. Wait a few minutes, then turn the breaker back on.
Can I reset the dishwasher using the app?
Some connected dishwashers allow you to reset or troubleshoot remotely through the manufacturer's app. For example, Fisher & Paykel's SmartHQ app provides control and support for compatible models.
Is it safe to open the control board area to reset it?
Only if you are qualified and have disconnected power. Opening the control board can expose live electrical parts. If you are not confident, contact a professional technician.
