How to Fix Samsung Washer Error C6
Problem: Calibration mode active

How to Fix C6 Error
1. This is not an error code, but an information code indicating the washer is in calibration mode.
2. Calibration mode is a necessary process that allows the washer to learn the weight of the drum and optimize spin performance. It should be run after installation or any significant repair.
3. Do not interrupt the process. Allow the washer to complete the calibration cycle, which typically takes a few minutes. The drum will rotate back and forth at various speeds.
4. Once complete, the display will show ‘End’ or return to a normal state, and the washer will be ready for regular use.

How to Fix Samsung Dishwasher Error AP
Problem: Access Point mode for mobile/Wi-Fi connection

How to Fix AP Error
1. UNDERSTAND THE MODE. ‘AP’ stands for Access Point mode. The dishwasher is broadcasting its own Wi-Fi signal so you can connect your smartphone to it for initial setup with the SmartThings app.
2. CONNECT YOUR PHONE. On your smartphone, go to Wi-Fi settings and look for a network named ‘[dishwasher] Samsung’ or similar. Connect to this network.
3. COMPLETE SETUP IN THE APP. Open the Samsung SmartThings app and follow the on-screen instructions to add the dishwasher to your home Wi-Fi network. The ‘AP’ code will disappear once the connection is successful.
