Product review (5 stars): Fixed a problem with my Kitchenaid Dishwasher
Our new (to us) condo had a new Kitchenaid dishwasher that was installed in 2015 but apparently never tested.  It was shutting off shortly after starting.  Since the warranty was expired, Kitchenaid wanted $$$ for a one year warranty or time and materials to come out and look. After some research, discovered how to run diagnostics and found a pressure issue with the drain circuit.  Since the dishwasher had a cabinet between it and the sink, the 8 foot hose supplied with the new dishwasher was apparently discarded and the original rubber hose with a larger inside diameter was re-used.  I believe the larger hose was causing some back pressure when water ran back down the hose from the air gap loop.  Installed this hose and saved some serious money!
