Total Membership Rules: 4*3*2*3*3*3*3=1944 rules

Multiplication of all the inputs of each membership function

Yeah, this is called the Curse of Dimensionality. But, what exactly is the output?

nRules = (2)*(3^5)*(4)

nRules = 1944

If you analyze the functions of the Laundry Washer, you should be able to identify what inputs can be eliminated (moved up to the hierarchy of the control logic) from the FIS to reduce the number of Rules substantially.
