Congratulations!
I've had mine since the early 80s. I love the sounds from the revolving Big Blue Wash Arm. I had trouble with the washing performance because the detergent in the main wash compartment of the detergent dispenser was getting partially washed out during the prewash. I tried a lot of different solutions and finally improved the performance, but the machine was not great for heavy or baked on soil. It was great for tableware right after a meal so I loaded all of the prep utensils in the 18. Surprisingly, it was better at washing the food grills from the Farberware broilers than the KDS18 because of the spray pattern of the wash arm. I would place the inverted grill on the row of supports in the middle of the lower rack then invert the stainless steel body of the broiler over it and it all got cleaned.
