Water fills up but the drum wont spin or drain. the model is LG-WM2487HRM

Thanks for choosing FixYa and welcome. If your washer doesn't drain or spin, you may read and learn what parts may cause this. First, you will want to check your water pump. You need to make sure it is working. Make sure you check the belt on the pump. Make sure it is not broken or loose. Also, make sure your pulley is not stuck in place. Sometimes, they will stick or barely turn at all. If this is the case, you will need to replace it. If the pump, pulley, and belt are working, make sure your motor is working. You should be able to hear it if it is. If it isn't, check your lid switch. The lid switch can cause the motor to not work. It may need adjusted. If not, go ahead and change it. A bad lid switch may cause the washer to not work at all. Now, if your pump is pumping and the washer still won't spin, you will want to check your belt and clutch. Once again, the belt may be broke or loose. Check to make sure your clutch is not worn also. This may be a case of a bad lid switch again as well. You could have a bad drive motor. This is what controls spinning, draining, and agitation. You could have a broken motor coupler. Over time, they will go bad and need replaced. It is possible that your transmission is slipping or damaged. And lastly, you could have a bad basket drive or spin bearing. This is what allows the inner tub to move. If this is the case, you will probably hear loud sounds or loud banging.
