Strange noises - drum not always emptying

Found a very stretched, loose pump belt. Was able to pull it off pump pulley and motor pulley easily. Pushed motor assembly toward transmission pulley and removed wider drive belt. Wiped all pulleys clean. There's a double on the motor- one for drive belt, one for pump belt. Removed two hoses from pump using nutdriver. Removed pump. New pump installed. Installed two hoses on new pump. Installed drive new drive belt. Installed pump belt last. Slid pump to near farthest spot in slots. Tested for correct tension by pinching pump belt. Should be able to pinch center so two pump belt sides come within 1/4" of each other just as the spring tensioned motor mount starts to move. Pused washer back into place after external hoses connected. All new hose washers and filters on both hot and cold. Ran, checked for leaks - none! Absolutely perfect. Put front panel back on. No weird noises and drum empties perfectly every time. My wife is so pleased she's doing more loads.
