I looked up the problem on the website, and parts were suggested. There were very helpful how-to videos along with the parts description. I ordered a tub suspension spring, and the three centering springs. They arrived in 2 days. With the video, I was able to remove the washer cabinet housing, and expose the tub. I found the on suspension spring was indeed broken, and replaced it. I also changed out the three other tub springs, as our kitchenaid superba washer is almost 30 years old. I put it al back together, with a total job time of about 45 minutes. Our machine is working perfectly again. I am very pleased with the whole experience with appliance parts pros. I highly recommend this company. Their website, customer phone service, and shipping are all excellent.
