Kitchen Large Electric Appliances - Plugging into GFIC Conector and Issue?

I just had a Miele Dishwasher intalled by the factor trained technician. When he went to plug it in, he notice a Ground Fault Receptacle. He said that he was taught in training class not to plug the units into a GFIC receptacle in that there was something in the monitoring circuits that would effect the motherboard. He said it might even void the warranty.

The technician seem competent but this did not seem to make sense. I checked the manual and there was no reference to the GFIC issue. I called the company's tech support line and they did not say there was an issue.

Has anyone on this board heard similar issues with GFIC and electronic appliances?

Thanks

I don't know about mother boards-I have an electric shears
( the kind Uncle Sam likes at induction ) Plug in upstairs GFCI
blows every time--Plug in downstairs GFCI, no problem.
Maybe they don't want any problems.................

Montanaro,

A GFCI receptacle shouldn't have any effect on whatever you plug into it. Sounds like hogwash. The company's tech support seems to agree.

That said, a GFCI might trip with certain things plugged into it, but they have improved the GFCI design over the years to the extent that it is almost a rare thing these days.

J HOWARD, have you replaced the GFCI upstairs to see if it is just a defective device?

Maybe mine just plain don't like shears.
If I replace it I will let you know what happens.
I don't go up there much anymore.
My youngest ( 40 ) dropped in for visit at Christmas.
Guess who is still up there....................
