2022 R27OB port side galley GFI outlet won't reset

[cliffm]

Today, our R27 port side valley GFI plug tripped and doesn't want to reset? We've had no issues running the same appliances since receiving it in June 2022. We've unplugged everything on the port side, galley and fwd berth, but after resetting it and the powering on the "cave" 115v breaker/toggle, it immediately tripped. Trying reset it while powered on fails immediately.

Is this GFI outlet marine specific? Or will any box store GFI suffice? This seems to be a premature failure?

I have had this fail twice and replaced both times with the standard household 120V 15 GFIC receptacle. Not exactly sure why they failed, but both times it seemed to be when I ran a drip coffee maker while on the inverter (not shore power)
Since not making coffee while on the inverter, I have had no failures in 3 years.

That's both interesting and good to know! We literally have been periodically running the same (3) items for over a year, the factory supplied KURIG pod coffee maker on the galley outlet, and a ceramic fan cube heater to take the chill out (during spring and fall) or small compact box fan, both from the fwd berth outlet beneath the TV (same circuit as galley)

Embarrassed to say we haven't even run the inverter since delivery training/testing over a year ago!
