Troubleshoot Karcher WD1 vacuum cleaner | Suddenly stopped working

Simple troubleshooting for my new karcher WD1 vacuum cleaner that only run for 2 weeks. I just want to share how I fixed the issue. I found loose connection on the carbon brush causing the terminal to burn. Overall this product is still good due to its power.
