I followed your instructions and all is well...so far. A few things I would add are: The metal plate that the 4) 5/16 bolts go through is covered with grease. Have a rag handy to wipe your hands off so as not to contaminate the magnets. I also noticed tiny metal flakes inside the white "wheel" and blew them out. If they were metal they would surely be attracted to the magnets and could actually be the problem. Thanks for the tip.

Re: F 51 code
Unplug the unit. Pull it forward and tilt it back about 45 degrees. Use a 6mm allen wrench to remove the botom center screw in the white "wheel" . Remove the "wheel". Remove the 4 5/16 screws that hold the coils in . Unplug the 3 pin connector and clean the male side pins. Reassemble in reverse.

I found this on the internet. May be of some help.
The F-51 error code on this washer indicates that the machine control board in the console detects a motor RPS (Rotor Position Sensor -- tachometer) failure. This can be caused by a number of different problems. You could have a bad RPS sensor, a failed motor, a wire harness connection problem or an item stuck between the spin basket and the outer tub that is interfering with spin basket rotation. A water filling problem could also cause this code to be displayed since the basket would have excessive friction if water is not entering the machine properly. With the washer off, spin the basket to see if it rotates freely. If you detect resistance or suspect that an item is stuck between the basket and the outer tub, you will likely need to remove the basket and check this area. The procedure for removing the basket is shown in the first image below. Remove the basket and check for foreign objects or debris.
If the basket spins freely, make sure that your water supply cut-off valves are fully open. Shut off the water supply and remove the hoses from the connections on the back of the washer. Place the ends of the hoses in a bucket and briefly turn on the water supply to check the flow and water pressure coming from the end of the hoses. Check the inlet water valve screens for deposits or debris that could interfere with the water fill. The motor will begin to spin the basket before the washer completes the filling function. If the filling is slow, it could cause the F-51 code.
If the water supply is okay, you could have a wire harness connection problem, failed RPS sensor or a number of other failures. If you are technically advanced and have a volt/ohm meter, you can use the technical information provided in the third image to try and diagnose your likely failure. NOTE: This information is intended for technicians. Follow electrical safety guidelines when using this information.
Unplug the washer
to disconnect electrical power before accessing internal components. Internal metal edges in the washer can be sharp. Protective gloves are recommended.
I recommend that you
unplug the washer
and access the control board first. Check the wire harness connections on the P10 and P5 plugs first. Measure the resistance through the motor and the RPS sensor as shown below. This may point you in the direction of your failure.
This is often a difficult failure to diagnose and repair in an Oasis washer. If you do not feel confident repairing this problem yourself, then you can have it repaired at your home by a Sears technician.
If You have the F51 code. The reason could be due to an intermittent connection at the rotor position sensor (RPS). To correct this, remove and install the the connector at the rotor position sensor (plug and unplug) at least three times to clean off any corrosion build up on the connector or the rotor position sensor due to the intermittent connection.
Confirm that the connector is fully seated onto the rotor position sensor upon final connection and verify that there are no damaged wires. The electronic control unit may have to be replaced, since the upgraded version is less sensitive to intermittent RPS connections.
Motor RPS Failure--F then 51 flashes when there is a motor rotor position sensor(RPS) senses rotation after stop command.F-51 ERROR CODE IS DEALING WITH THE SPIN CYCLE. THE CONTROL DOES NOT DETECT IT SPINNING.THE RPS SENSOR ON THE BOTTOM OF THE UNIT NEEDS TO BE TAKEN OFF AND PUT BACK ON ABOUT 10 TIMES. SOUNDS WEIRD BUT USUALLY FIXES IT.But if that does not help then it needs to be replaced.You can get required parts from www.repairclinic.com Thanks. Keep updated for any more query.

Hello, It is a rotor position sensor code. The control is no longer receiving
a signal from the motor. It can be a failed sensor or control, but
usually it is a bad connection where the wires plug on to the sensor. Thanks
there is a rotor position sensor failure.look under the top hood of washer on the inside of the front of washer and you will find a tech sheet that will help with this problem use a flat blade to push two clips in to get hood up.
The F51 error code indicates that the control is not sensing proper motor movement through the signals from the RPS (rotor position sensor) circuit. This can be caused by several different problems. Make sure that you are not overloading the washer. Overloading can cause this problem. A toy or foreign object could be under the washer that is interfering with motor rotation. With the washer empty, spin the basket inside the washer tub to see if it spins relatively easily. If not, you could an item caught between the spin basket and the tub. You could have a wire harness problem causing signals to not be transmitted properly between the RPS and the machine control board. A failed RPS sensor or a failed control board could also cause this problem.

It is a rotor position sensor code. The control is no longer recieving a signal from the motor. It can be a failed sensor or control, but usually it is a bad connection where the wires plug on to the sensor. If the machine is less than a year old, it will be repaired in warranty. If not, post back and I will try to walk you through the repair if you want to try it.
