gfi trip
It may appear that the gfi is tripping due to water fill, but it may be due to current surge due to heater kicking on. DW pumps draw 1 amp. The heater can draw 10 amps. Check the rating on the GFI breaker and be sure its over the installation recommendations from Whirlpool. Also, breakers will typically trip at progressively lower current levels as they age and the more times they trip. It may just be worn out.
