Error Codes & Indicator Lights
Error codes and flashing lights are your appliance telling you exactly what's wrong — if you know how to read them. Most error codes point to a specific component failure or a condition the appliance detected (overheating, water level, door ajar). The fix is almost always straightforward once you decode the message.
