The part is listed as "4 Button" yet the part on my appliance is a dial/timer. I'm not certain what "button" means. Also, is there any reason I cannot install this part myself. I am reasonable adept with tools and mechanical things. I would presume the wiring is color coded.
Answer Del, The "Four Button" refers to the number of buttons on the selector switch 99001848 on the control panel. You didn't mention an issue, but if you have basic skills, you should be able to repalce the timer yourself. In fact the timer has a multi plug connector, and will only fit and lock in place one way. You'll need to remove power to the dishwasher before you do anything, remove the inner door liner, and then remove the cover panel to access the timer, remove the timer knob and dismount the timer. As long as you don't disturb the other wires to the other components, you'll be fine, but yes the other wires are "color coded" .
