Had a service call to a customers friday cord connected dishwasher in commercial kitchen keeps tripping gfci. Replaced gfci receptacle with gfci breaker installed inuse cover. Received call sunday afternoon gfci tripped. Talked to owner obout problem and informed him we need to get the repair tech out to look at the problem informed him i would be able to meet him monday morning. Talked to the tech this morning and he said this should be hard wired and that i should remove the gfci breaker. I said i was not comfortable with that solution because the machine has a ground fault. Its not constantly tripping only ever other day after heavy use. Am I over reacting, the machine was installed with a male cord end by the installer and i know that it does not need to be ground fault protected but I am not comfortable doing that.
 
If it's in a commercial kitchen, and the dishwasher is plugged in and is 120v then it needs to be GFCI protected. If it's hardwired then it's not required to be GFCI protected. If it's tripping a receptacle then it's probably an issue with the appliance.

You need to read 210.8 (B)(2). What dose the mfg. instructions say regarding cord and plug or hard wire? Sounds like after heavy use it may be getting water into the motor or the bearings are worn and is causing the motor to overload
 
I've had that same thing happen to me before. It involved an ice machine in a Starbucks. The service contractor had the appliance contractor tell me to not ground fault the circuit on an ice machine. I was evidently an idiot to ground fault the circuit and it was my fault for the service call at 9 oclock at night. That's when I discovered the hard wired solution but I sill GFCI'd the circuit. It was originally plugged in to a GFCI receptacle. Receptacle burned out and I replaced it, that is how I got involved. The gratuitous free warranty call back and drubbing of personal criticism.

DUH, water, electric, ground fault problem, ice vending machine.

I new it was an equipment problem and I didn't care what the appliance guy said that night on the phone. The service company rep was mad (pissed, yelling, swearing). The principle of the service company was on the phone at 9pm at night. It involved his continuing to service the Starbucks chain for the state. He should have been yelling at the appliance guy.
I'm still in business, the appliance company is in business and flourishing, the service company is not.
Do what is right. Don't get pressured into doing something dumb by over aggressive greedy desperate people. The problem was the open motor in the ice machine. It had a sign on it to always replace the plastic cover over the motor (it was missing). No Iced Starbucks from that machine. They had to go next door to get ice from the grocery store. Bummer, way too much systematized greed. Should have listened to the smart electrician that could read.

Hard wired equipment has more assurance of having an effective equipment grounding conductor connected to the appliance. How many times have you seen a damaged or missing equipment grounding pin on a cord cap? With GFCI protection, you still have pretty effective shock protection for users should the frame of an appliance become energized if there is a defective EGC in a cord cap.

Yup, we've all been there. For me, it was a GC operating a worn-out pipe threader he had borrowed from a guy who found the ancient machine 'at auction' twenty years ago. The GFCI kept tripping, it must be the fault of the GFCI and the stupid electrician that put it in.

Never, not once, did the doofus consider that maybe the GFCI was keeping his guys from getting zapped. Even when they ran a longer extension cord to a non-GFCI outlet and saw sparks when the machine ran - it was that damn GFCI and the idiot electrician. When a guy got a shock, HE was the cause, because his gloves were wet. Never was the idea entertained that -maybe- that piece of kludge belonged in a landfill.

You can't fix stupid.
