At first, all I wanted was the drain hose. I could not find a drain hose by itself, I needed to order a full air brake and drain hose kit. I thought I could use the drain hose and keep the air brake for the future. When the kit arrived, it looked nothing like the hose/brake assembly on the dishwasher. With the help of appliance parts pros staff, I discovered the hose/brake assembly was completely and profoundly re-designed; I needed to remove both old parts and install the new air brake and drain hose supplied in the kit. I found a YouTube video on installing the new parts that showed me which tube was hooked to which port on the air brake. Following the video instructions, I installed the new parts in less than an hour and had the dishwasher running like new. The only change I made was to use stainless steel clamps on the hoses to control the pressure placed on rubber/plastic connections.
