No power to dishwasher

I had a call from the wifes friend, the dishwasher not working, I checked all the service panel but no dishwasher. So I went under front to remove panels so I can see the wiring. Found the unit hard wired in. Use my beeper and multimeter but not power. So I was getting frustrated, so I looked around the kitchen and found the fish tank wasn't running, So I started reseting the GFCI's on the counter and behold, one of them reset the dishwasher. This machine had soapy water sitting for a long time since the smell woke the dead. Anyway, is it by the code to wire something like this? I mean, you know an outlet on top and a machine below. Correct me if I am wrong but do GFCI outlets have a lower amperage rating? If this is wrong then all these home owners here need to get the builder and make it right. Your feedback is greatly appreciated, Thank You.

The dishwasher should be on a non GFCI circuit, usually dedicated. It is not that the GFCI has a lower amperage rating (they are rated at 15 and 20 amps). It is the differential between the hot lead and the neutral or ground that determines when it trips. When that differential reaches about 4 milliamps, it will trip, indicating a fault. If it is a new house, the builder has problems and should address the circuit in question. Any dead fish?

The electric code prohibits having fixed in place appliances like the DW from being on the small appliance countertop circuits.

I agree with pcboss. Unless this is a pretty old house, the dishwasher should never have been wired on the same circuit as kitchen or dining room receptacles.

My old house had the dw and small appliance outlets on the same circut built in 1995.

Also, don't hire a handyman or builder to do electrical work as alot (but not all) of them had no training or do not know what they're doing. We will be glad to help you do it yourself if you wish.

Thanks for your feed back, I will let them know. I know the safety procedure only takes static electricity to open the GFCI. I guess somebody forgot to turn off the xerox machine when duplicating homes...LOL
