So I ran extension cord from dishwasher to bathroom GFCI outlets, no problems, next I ran to another separate circuit in the house with no problems.

The bottom line is that the dishwasher will blow all GFCI outlets on the one circuit, but works on all other circuits. Am assuming there is a problem with that circuit or one of the outlets.

Anyone have any thoughts?

Thank You
these other circuits are they gfci circuits as well ?
or are they non gfci circuits ?
will it work on any gcfi circuits at all ?

usually if a gfci blows this indicates a small electrical leak to ground,
the unit can still work in this condition, but the danger is higher.

The dishwasher concerned will have a "Calrod" heating element - similar to that used on electric cook-tops.
The insulation inside these "rods" is a type of ceramic material, which can absorb moisture if the seal where the connection is made is not completely air tight. Even a small amount of moisture can provide a "leakage" path to the earthed metal outer casing - which will trip a GFCI.

For this reason, in this country, such heating devices (Stoves, Water Heaters etc.) need not be protected by a RCD or RCBO if they are permanently connected to a dedicated circuit (or via a "non user accessible" socket outlet on a dedicated circuit.)

You said that it was a "lightly used appliance", which makes the ingress of water between uses quite likely.
I suggest that you run the device via a lead from a non GFCI protected outlet temporarily and see if this "dries out" the fault when it is plugged back into its normal outlet.

If it does not then operate without tripping the GFCI, you could either
replace the heating element or
run the device on a non GFCI protected (dedicated ?) circuit.

My choice would be the latter.
