Everything else about this problem
Is it an emergency?
Is an LG dishwasher error code an emergency?
Usually not an emergency — the code is the appliance reporting a fault it detected. Note the code, then turn it off at the breaker for a minute and back on. If the code returns with a burning smell, smoke or a leak, leave it off and call a pro.
Symptoms & causes
The LG dishwasher display shows a flashing error code, indicating a detected fault within the appliance's operation. Common LG error codes often point to issues with water intake, drainage, heating, or sensor malfunctions. Root causes can range from clogged filters and faulty water valves to more complex problems with the main control board or circulation pump.
Tools & parts
You will likely need basic hand tools such as a Phillips head screwdriver, a flathead screwdriver, and needle-nose pliers for disassembly. A multimeter is essential for testing electrical components like the turbidity sensor or the flow meter. You might also need a replacement drain pump or a new water inlet valve depending on the specific error code.
Safety first
Always disconnect the dishwasher from its power source by unplugging it or shutting off the dedicated circuit breaker before beginning any repairs. Turn off the water supply valve to the dishwasher to prevent leaks or flooding during component replacement. Be cautious of sharp edges inside the appliance and potential residual hot water if the dishwasher recently completed a cycle.
When to call a pro
If the error code points to a main control board malfunction, or if multiple components test faulty, professional assistance is recommended due to the complexity and cost of these parts. Issues involving sealed motor assemblies or persistent electrical shorts that are difficult to track down often require specialized tools and expertise. Furthermore, if you are uncomfortable working with high voltage or water lines, a certified technician can ensure safe and correct repairs.

What should I do if the error code persists after basic troubleshooting?
If the error code persists after checking filters, hoses, and resetting the appliance, it's time to consult the owner's manual for specific troubleshooting steps. You may need to test individual components with a multimeter or consider calling a professional technician.
How do I reset my LG dishwasher to clear an error code?
To reset an LG dishwasher, first try pressing and holding the 'Start/Pause' button for a few seconds. If that doesn't work, completely disconnect the power to the dishwasher for 5-10 minutes by unplugging it or flipping the circuit breaker, then restore power.
