Says bucket full when it was not

The forums indicate that one solution for this problem is replacement of the sensor assembly, which is what I did. Upon switching the sensor assembly it DID work for one bucket full, but then went back to indicating bucket full when it isn't. Other fixes indicate changing the switch assembly, which I tried to do but the part has been discontinued. The only other item is replacement of the main computer, which the cost added to the cost of the sensor assembly would equal the cost of replacement of the appliance, so I won't go there.
