Dishwasher froze - What is likely to be damaged?

If you want to know if there are any other leaks before spending $70 + installation on a new inlet water valve, just pour a bucket of water into the dishwasher and run it to see if there are any leaks. You have to put enough water in there so that the float switch ( on the bottom right or left front corner of the tub) knows that there's enough water to wash properly. You may , if something has frozen and cracked or broken, find a leak even before you run it, so pour the water in slowly while someone with a flashlight keeps watch under the unit for leaks. If you don't see any, then put enough water in to run it to see if it leaks under pressure. If you find that all you need is the inlet water valve, they are easy to replace, so don't waste money having it installed. Good luck!
