My LG washing machine repeatedly trips GFI circuit breakers. It does this on two different circuits with different breakers. It does not trip a non GFI circuit breaker. The LG repairman says we should not use a GFI breaker with this machine. Is this safe? Should we replace the washing machine or use the non GFI breaker as suggested by the repairman?

This tells me that you do not have an overload situation. There is a short, and/or one or more faulty breakers possibly including the main breaker.
Even an experienced DIY'er with electrical knowledge would probably contact an electrician at this point. If there is a potential problem with the main breaker then it is best to get professional help.
You say you checked "socket" and the "fuse," did you mean the AC wall outlet (115V) and a fuse or breaker in the main power panel? Nearly all circuits involving water are protected by a Ground Fault Interrupter that can be servicing several wall outlets (perhaps one not near the washing machine) or can be located as part of a circuit breaker in your main power panel. The GFI outlets will have one or two push buttons located between the outlets and a combination GFI/overcurrent breaker will also have at least one button where others will have none. If you find one that is tripped, try resetting it. If it will not reset, unplug the washing machine and try again. If it now stays on, your machine may have an electrical path causing it to trip and using an unprotected outlet may be unsafe and an indication that the appliance itself may have electrical leakage which could be otherwise dangerous. The circuit breakers in the main power panel can also fail (they didn't 20 years ago) and we have replaced 3 in a home only 5 years old already so they are not made well anymore.
i would install a regular outlet... and if the circuit breaker blows. then their is a direct short within the washer .i never heard of GFI being used on a washer ..remove it.. their may be other outlets on this circuit also that can adding to it tripping. like frig.. find out what is on that circuit by shutting off the breaker for washer see what else goes off...
That to me seems like an electrical problem. Every now and again you can get a bad GFCI receptacle that will constantly keep tripping. I would also see that the GFCI is properly sized for the circuit. It needs to be a 20 AMP circuit (just dedicated to the washer) and a 20AMP GFCI receptacle. The way to tell is the 1 of the three prongs of the 20AMP GFCI will be in the shape of a "T" while a 15 AMP will have 2 straight prongs and the ground prong. Hope this ws helpful, don't go spilling any money into your washer without getting that fixed first, because it doesn't seem like a washer problem.
The ground not being connected does not tirp thr gfi. The gfi senses the current between the two legs it will trip when the current returning to ground (neutral) exceeds 5mili amps. This is for personal protection. If you have a gfi circuit breaker disconnect the black wire from the breaker, if it does not trip you likely have a groung fault in the washer. If you have a dryer or other metal object that is grounded (Bonded) you may get a shock from it, also standing (barefoot) on a concrete floor may cause the same. ( bonded is a gronded conductor that attaches all metal parts of a electrical curcuit together) a hot lead goes to ground is a dead short and will trip any breaker.
I ran into this problem with a washer this summer. the gfi breaker needs to be replaced. it is weak and trips easily. if you can run an extension cord to an outlet without the gfi andrun your washer, you probably will not have any issues. that is what I found with the washer this summer. when it was plugged into the gfi, itwould trip. but when I had it plugged into a regular outlet, it was fine.
