Tip & How-To about Dishwashers

Wont start or dead dishwasher, no lights, no power, thermal fuse

If you have a dishwasher that is not doing anything, the first thing to check is the incoming power. Make sure the circuit breaker is on and not tripped.

Another place to loose power to the dishwasher is under the sink if it is plugged in to an outlet. It could have come disconnected.

The third place to look is a wall switch. If you have a switch that does not operate a light in the kitchen it may be connected to the dishwasher power source.

If all of these are okay the next place to check is the junction box of the dishwasher. To check here you will want to turn the breaker off first or remove power from the cord before taking panels off. By removing the kick plate or lower panel on the dishwasher you can access the electrical junction box. Many times the wire connectors were not properly installed in this box and over a period of time the connection is lost. This connection should be made by a professional.

If we have power to the dishwasher a common component to fail on many brand such as Whirlpool, KitchenAid, Kenmore, Maytag is the thermal fuse. This device is a two wire heat activated fuse that if tripped will disable the dishwasher. This thermal fuse is attached to the control circuit board that is usually in the console in the upper portion of the door. It can be checked with an ohmmeter just like a regular fuse. When replacing this fuse it may come as a kit with wire connectors, be sure to use all of the parts in the kit. The fuse often will blow due to a loose wire connection on or near the fuse, that is why new connectors are supplied.

A sample image of a typical thermal fuse kit is shown below.

kenmore 665 no power

No power at all? First thing to check is that the dishwasher power cord is plugged in under the sink. Make sure the plug didn't become dislodged. Then, check the circuit breaker at the electrical panel to make sure the breaker didn't trip. Open up the door to the electrical panel and look for a switch marked "dishwasher" or "kitchen outlets." Switch it off and then back on to reset it. Those are the easy fixes. Next you'll need a repairman.

chris renieri, there are a few things to still check before we say it needs a new board. here is a list to check. please make sure the power to the dishwasher is off before you start checking.
1. Please check the incoming power at the dishwasher. This is located under the door behind the black panel to the right side. Please check the ground wire. there should be two wire nuts ( caps) connecting the wires. These can come lose if not properly connected.2. I am not sure about the building codes in your area but the dishwasher is typically hard wired into an outlet box. (you mentioned it was plugged in) 3. please check the breaker box to see if the breaker has been tripped.
hope this helpsJoe Connnolly

No console lights. Where are the fuses, if they need to be replaced?

There may be fuses in it but first check to make sure the line where it gets its power is 'live.' There is normally a standard outlet (often under the sink) that may be dead. If you find one, plug some other appliance into the outlet to make sure power is available.
Anything located near plumbing is likely to have a GFI (Ground Fault Interrupter) on that circuit and it may have disabled the outlet. If no GFI is visible in the kitchen area, there may still be one in the main breaker box of your home.
Check these things before doing anything on the dishwasher.

Washer stopped mid-cycle, water in the bottom of the tub. Circuit breaker popped due to over-load. Reset breaker and it immediately popped again. Could this be cause by a jam in the grinder assembly?

My dishwasher just quit mid cycle. (still has water in it) It is a whirlpool partner 1. I checked the breaker and it wasn't tripped... but i reset it anyways. When I tried the dishwasher again it worked for a second and turned off. I have done reading about the thermo fuse but can't find it. Not sure how big of a problem this is.
Dishwasher is 5 years old.

Two days ago my LG dishwasher model lDF 7810BB worked fine. Yesterday I loaded it and the display panel will not light nor show any sign of power. I check the circuit breaker several times and all other electrical items work fine in the kitchen. The 2 year warranty expired 9/08/08

Check for voltage with a multimeter at the wires very near the front, just behind the kick plate. Follow the incoming electrical wire in and remove the little plate the covers the wires/wire nuts. I have seen wires that appear to be connected properly but the circuit is open.
Or, even though the circuit breaker is not switched open, the circuit itself, supplied to the front of the dishwasher is not live/hot.
Good Luck!
