How to Reset Dishwasher Error Codes
Short answer: Most dishwasher error codes can be cleared with a power cycle: turn off the dishwasher at the circuit breaker or unplug it for one minute, then restore power. If the code returns, check the owner's manual for a model-specific reset or a factory reset. Persistent codes usually indicate a hardware fault that needs a service technician.
What Dishwasher Error Codes Mean
Modern dishwashers rely on a control board and several sensors to manage the wash cycle. When the system detects something outside the expected range, it displays an error code on the digital screen or flashes a combination of indicator lights. These codes are diagnostic messages that point to a specific condition, not necessarily a permanent failure. Some codes appear once and clear without any action.
ENERGY STAR materials note that certified dishwashers include innovations such as soil sensors and improved water filtration. These sensing systems can trigger codes when they detect irregular water flow, temperature, or pressure. Understanding that the code is a signal from the sensing system helps you decide whether a simple reset is appropriate. Learn more about how soil sensors work in our soil sensor explainer.
When a Reset Clears the Fault
A power-cycle reset is worth trying when the dishwasher stalls mid-cycle, the control panel becomes unresponsive, or a code appears after a brief power outage. It also works for transient errors caused by a door that was opened while the machine was running or a momentary surge in the electrical supply.
Do not rely on a reset if you observe water pooling under the unit, smell burning, or hear grinding or rattling noises from the pump area. Those symptoms point to mechanical or electrical damage that a reset cannot address.
How to Perform a Power-Cycle Reset
The most universal reset is a full power cycle. Start by switching off the circuit breaker that feeds the dishwasher, or unplug the unit if it has a cord and plug. Wait at least one minute so the control board capacitors discharge fully. Then restore power and wait for the control panel to light up. Press the Start button, or follow the instructions in your owner's manual to clear the displayed code.
Some models require holding down a specific button combination for a few seconds, such as Cancel and Start together. The exact sequence depends on the brand and model. Locate the troubleshooting section of your manual, or search the manufacturer's support website. If you no longer have the paper manual, most makers host downloadable PDFs on their official pages.
Brand-Specific Notes
Brands like Bosch and Fisher & Paykel embed unique reset routines in their control software. Bosch's official site includes product support resources and owner manuals, where you can find the procedure for your specific model. Fisher & Paykel, known for its luxury dishwashers and drawer designs, also provides service documentation through its official channels. In most cases, a simple power cycle clears transient codes, but a recurring code may require a factory reset that is only described in the manual.
Never open the control panel or tamper with the internal wiring to force a reset. Doing so can void the warranty and create a shock hazard. If the manual's instructions do not resolve the issue, contact an authorized service technician. For guidance on choosing a drawer model, see our drawer dishwasher buying checklist.
Common Error Code Groups
Error codes generally fall into a few categories. Drain codes appear when water fails to leave the tub, usually because of a clogged filter, a kinked drain hose, or a blocked drain pump. Water supply codes indicate the dishwasher is not filling, which can stem from a closed supply valve, a faulty inlet valve, or low household water pressure. Heating and drying codes point to issues with the heating element, thermostat, or the vent system.
For help with a specific symptom, see our troubleshooting guides on not draining, not filling, not heating, and cycle stops mid-cycle.
When to Call a Service Technician
Call a professional if the same error code returns immediately after a reset, if the dishwasher trips a GFCI outlet, if you see any water leaking, or if the manual explicitly states that the code requires service. A reset cannot repair a failed drain pump, a stuck float switch, a blown thermal fuse, or a damaged control board. Those components need replacement.
Before calling, write down the exact code and note what the dishwasher was doing when it appeared. This information helps the technician bring the right parts and diagnose the issue faster. If you are weighing repair against replacement, our repair vs replace guide can help you decide.
How to Avoid Common Error Codes
Many error codes stem from neglected maintenance. Clean the filter regularly and clear food particles from the spray arms. Check the drain hose for kinks or clogs, and make sure the supply valve is fully open. Running hot water at the sink for a few seconds before starting the dishwasher ensures the inlet line is warm, which helps the water heater reach the proper temperature.
Hard water can leave mineral deposits in the inlet valve and heating element, producing temperature or flow errors. If your water is hard, consider using a dishwasher water softener or a descaling product periodically. Our filter cleaning guide walks through the steps for keeping the filtration system clear.

Questions
Will resetting my dishwasher erase saved settings?
A simple power cycle usually clears the error code without erasing your saved wash preferences. A factory reset, which may involve a longer button sequence, can restore default settings. Check your owner's manual for the exact behavior.
How long should I leave the dishwasher unplugged?
One minute is enough to discharge the control board capacitors. Some manufacturers recommend waiting up to five minutes for stubborn codes. If the code persists after a five-minute reset, treat it as a hardware issue.
Why does the same code keep coming back after a reset?
A recurring code means the underlying fault is still present. Common causes include a clogged drain filter, a failing drain pump, a stuck float switch, or a faulty temperature sensor. Schedule service to diagnose the part.
Can I reset the dishwasher without unplugging it?
Some models have a dedicated reset button or a button combination, such as holding Start and Cancel for three seconds. A full power cycle is more reliable because it completely de-energizes the control board.
Does a reset fix a dishwasher that will not start at all?
Sometimes. If the control board froze, a power cycle can restore it. However, if the door latch or door switch is faulty, the dishwasher will still refuse to start because it thinks the door is open.
