The only load sensor is part of the control board circuitry which senses the load on the motor & adjusts the wash motion to suite. Don't think this applies for the spin mode. It can't just wear out. If control board is the problem then it will need replacement. What do you mean exactly when you say it won't spin a full load? Does it not spin at all? Does it spin slowly or just keep stopping? Any beeping or error codes?
