Testing a Dishwasher Appliance for Power

Dear Mr. Electrician: How do I go about testing my dishwasher appliance for power?  Last night, I tried to wash dishes, but nothing happened.  There were no sounds or visible indicator lights. Answer: Testing a dishwasher appliance for power is a good starting point.  However, an appliance such as a dishwasher usually requires the services of an appliance technician for repair and not the expertise of an electrician.

TESTING A DISHWASHER APPLIANCE FOR 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, 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 machine running again, you will need to look inside the dishwasher.  Start by removing the bottom front cover to expose the components of the dishwasher.  This is usually accomplished by removing a few screws on each end or pushing 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 for removal.  The dishwasher owner's manual may have detailed steps for the cover's removal.

At 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 voltage on the cord or cable, 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 no power.
