The washing machine did not drain. Turned to setting for it to drain but it just hummed. Thought it was pump so I removed pump from machine and it turns fine and don't see any broken pieces. Reinstalled pump and noticed that the center pulley wheel was only turning when manually turned. The agitator now doesn't appear to be turning during cycle unless when middle pulley wheel is turned manually.

Most likely there is something stuck in drain pump open the drain pump hose and check if something is stuck there.

Your pump is jammed with a blockage, remove the filter and check the pump behind it is revolving, usually a hair grip or button in there...remember the washer is full of water so you will have a lot of water coming out

The humming noise is due to the drain pump being jammed due to clogging of dirt. All you need is to remove the drain pump and do a full clean up. You can also try to tap on the drain pump while it is humming as it will release the dirt and wash off.

.It is possible that lack of voltage to the pump or fault in the pump can cause the hum. If there is intermittent power to the drain valve/pump then the program controller unit is a suspect.

Hi tdld6365,

Drain pump may be clogged. Even though you replaced the pump, the filter may still be clogged. Please follow my below tip on the fix:

ACCESS, DRAIN & CLEAN THE DRAIN PUMP FILTER...

If this does not help, the drain pump may be faulty.

Kind Regards

hello sir,
Please do the following checks 

1. nspect the drain hose for kinks
   
2. Test the timer control
   
3. Test the lid switch (some models)
   
4. Inspect the water pump
   
5. Inspect the drive belt (belt drive only)
   
6. Inspect the motor coupler
   

Click on the highlighted words for details on how to check. 

the washing machine uses an electric pump. Unlike the older machines pumps that used to be driven by a belt, Then newer washers pumps are driven with an electric motor.The first thing you need to do is to disconnect the washer from the wall outlet
Next you need to remove the front panel from the washer. To do that you will need to be use a spatula. You need to place the spatula between the front and top panels to compress the two front panel holding clips.
After removing the front panel you need to connect the washer to the wall outlet.
Set the timer on the spin cycle and pull the knob to turn the washer on. Listen to see if you could hear the motor on the pump turning or humming. since the motor hums, that is an indication that something is preventing the pump motor from starting.
Disconnect the washer from the wall outlet, empty the water from the machine (make sure you have plenty of towels to clean any water spills) this connect the hoses from the pump and check the pump for any obstructions.
If the motor on the pump is not running at all, then you'll have to check the pump motor for continuity. If the pump motor checks OK for continuity then you need to check the two wires that connect to the pump to make sure that the timer is sending 120 volts to the pump.
In conclusion, is not that hard to find out why your front load washer is not draining. You either have an obstruction, a bad pump or a bad timer.
To check the motor in the electric pump you will need to get the multitester. analog multitester. Make sure you read the instructions on how to use you multitester to read resistance and voltage

first check that your drain pump is working,reset appliance and put on drain only,listen for the pump to pump of hum,if it hums there is a blockage,remove filter and check,this is discribed in you manual
