Whirlpool, KitchenAid and Inglis dryers all have this style of idler pulley. This one was squeeling and was quite worn. I did a close up of the wheel shaft where you can see it has worn the hole oblong.

The August ’06 Consumer Reports Canada magazine has an interesting chart on page 37 showing Brand Repair History. Most of the dishwashers fell within 4% points of each other which is not surprising – many dishwashers are much the same in both quality and design. What is interesting though is the relationship between the number one product in terms of least repairs which is Whirlpool and the worst product in terms of repairs which is Fisher Paykel. You see Fisher Paykel makes Whirlpool’s built in drawer style dishwasher. I guess that brings everything in full circle when it comes to which dishwasher is best and which is worst. (The worst is also the best.)
