Testing a Dishwasher Appliance for Power

Dear Mr. Electrician: I use my dishwasher for storage and occasional dish washing. Last night I tried to wash dishes, but nothing happened.  There were no sounds or visible indicator lights.  What could be wrong? Answer: An appliance such as a dishwasher usually requires the services of an appliance technician for repair and not the expertise of an electrician.  However at the very least you can check to see that the dishwasher has power going to it.  NOTE: Text links below go to products on Amazon. Testing a Dishwasher for Electrical Power First make sure that the fuse or circuit breaker is not off.  Go to your home's main fuse box or circuit breaker panel and reset the circuit breaker for the dishwasher by pushing fully to the "Off" position and then to the "On" position.  If you don't know which circuit breaker is for the dishwasher, then reset them all.  If you have fuses instead of circuit breakers, replace the fuse for the dishwasher.  Now check to see if the dishwasher is working again. If resetting the circuit breaker or replacing the fuse does not get the dishwasher running again, you will need to look inside of the dishwasher.  Start by removing the bottom front cover to expose the components of the dishwasher.  This is usually accomplished by the removal of a few screws on each end or the pushing of some clips to release the panel.  It is also possible that the bottom cover is just hooked in place and only needs to be lifted up for removal.  The dishwasher owner's manual may have the necessary steps detailed for the cover's removal. You will need to get down on the floor in order to work inside of the dishwasher.  A furniture pad or blanket placed on the floor will make this a little more comfortable.  In the bottom of the dishwasher you should see a small electrical box with a cord or cable going into it.  Use a Non-Contact Voltage Tester and touch the side of the cord or non-metallic cable to see if there is electricity.  The non-contact tester will not work properly with a metal jacketed cable such as Type AC (BX) or Type MC cable. If the non-contact tester indicates that there is voltage on the cord or cable, then you should shut off the power at the fuse box or circuit breaker panel.  Remove the fuses or shut off the circuit breakers until the non-contact voltage tester indicates that there is no power there. With the power to the dishwasher OFF, remove the cover on the small electrical box located on the bottom of the dishwasher.  Double check the wires inside the small electrical box with the Non-Contact Voltage Tester.  If it still indicates that there is no voltage present then disconnect the white and black wires.  Using a pigtail socket with an ordinary working light bulb, connect the pigtail socket wire leads to the cable or cord coming into the dishwasher electrical box.  Be sure to cover the ends...
