How to Troubleshoot & Replace Lg AP4439145 / 5214FR3188G Washer Pump Drain Hose

Purchased & Installed new drain hose 

Replaced all the parts at the pump. Wasn't going to take the washer apart and replace only what I thought was leaking. Not that expensive to just buy all the parts and replace them. Installed new pump, drain bellows from the tub, drain hose, pump casing with new hose connector and basket. 

EMPTIED THROUGH BOTTOM DRAIN FILTER 3 TIMES BEFORE I LOOKED UP ON INTERNET ALL SAYING DRAIN PUMP NO GOOD. OK ORDERED DRAIN PUMP PLUS HOSE FOR DRAIN WATCHED 5 U TUBE VIDEOS TOOK WASHING APART HAD A PUZZLE TO PUT BACK TOGETHER. ANYWAY APPLIANCE PARTS GOT ME THE RIGHT PART TO INSTALL AND AFTER ABOUT 6 HOURS OF MY CHEAP LABOR WASHER RUNNING LIKE A CHAMP NOT TO MENTION THE FAST SHIPPING, AND THE KIDS TAKING HOW MANY SHOWERS A DAY AND CHANGING HOW MANY TIMES A DAY WE R UP TO ABOUT 13 LOADS AND PARTS PRO PARTS STILL KICKING ASS. THANK YOU FOR FAST SHIPPING
