Install a plug behind the dishwasher.
NEVER install the DW recep BEHIND the DW. Troublesooting a DW circuit becomes much more difficult when you have to pull out the DW just to test power. I had to do this last week and I was CUSSING the idiot who installed it.
Install it under the sink where it's accessible and run the pigtail thru the cabinet.
Stop making my job more difficult than it has to be :jester:
Job: tshoot power to DW.
1. Open sink base door, unplug DW and stick wiggy in. 20 seconds.
2. Empty DW, locate and remove countertop screws, remove kick cover plate, find no accessible jb in that little 3" space but I do find that there is no tile under DW and the legs must be adjusted up a half inch @ an 1/8 turn at a time, try to pull out DW and find the water supply is too short, disconnect it and put a pan under the worn out angle valve to catch the dripping water, test power and reinstall. 20 minutes.
