Dishwasher error codes are diagnostic messages that tell you exactly what failed. The most common codes relate to drainage issues, water supply problems, door latch failures, and heating element faults. Some can be fixed by resetting the dishwasher (unplug for 60 seconds), cleaning the filter, or checking the water supply. Others need a professional dishwasher repair technician.
Your dishwasher is flashing an error code and won't run. Before you panic, that code is actually helpful — it's telling you exactly what went wrong. Here's what the most common error codes mean for every major brand we service in Port St. Lucie.
