It seems my under kitchen sink outlet only allows two devices at once. I have a wall outlet and I have an adaptor that converts the 2 outlets into 6 outlets.
Then, I plug in the dishwasher and insinkerator into two of the 6 outlets and they both work. Then I plug in the insinkerator and the water purifier they both work. However, when I plug in all three, the water purifier stops working.
Note the dishwasher is 3 prong, insinkerator is 3 prong and water purifier is 2 prong.
What is going on here?
