I have a Kenmore model number 665 dishwasher. It's suddenly stopped working. There is power at the terminal box and the water is hooked up. There are no lights on the control panel.

You will need to troubleshoot this dishwasher. Look at this: https://www.youtube.com/watch?v=zex_g2TJRl4. You need to buy a good multimeter and learn to use it. Here are some manuals: https://dl.dropboxusercontent.com/u/8010163/How%20to%20use%20Test%20Equipment%20Service%20Manu al.pdf

On some of these dishwashers, and other appliances a bad batch of capacitors was used and you will find many that are bad that you can see are bad because they are swollen and the area around the capacitor is burned. Look for any burned or brown areas on circuit boards. A good meter can be purchased at Home Depot for $17.98 (Commercial Electric Digital Multimeter-MAS830B - The Home Depot (http://www.homedepot.com/p/Commercial-Electric-Digital-Multimeter-MAS830B/202353293?N=5yc1vZboff#customer_reviews))
