My LG washing machine wm2050cw stopped working. When running a diagnostic test, pressing the start/pause button one time, the tumble will spin between 40-45 rpm. Pressing 2 times, it does not spin anymore at all. Pressing 3 times and still no spin. Can you please help troubleshooting, I would like to repair it myself so I can save some $ as my budget wont allow me to buy a new. Thank you in advance for your help.
