Gfci replacement plug power washer.
Road home 18 in.
Works with all residential models.
So the gfci was in fact part of the power washer and was getting hot but when replaced with a non gfci plug and plugged into a gfci receptacle everything went along fine.
Gfci replacement plug power washer.
For pricing and availability.
If i were you i would replace the cord with a 3 wire and just plug it in the garage gfci receptacle.
Sounds like a bad part of the power washer.
So with a 2 wire gfci plug and the washer sitting on dry ground it still tripped.
Actual product may appear differently than in the photo with updates and upgrades but will still work with all residential models.
It should be about 3 1 8 x 2 1 5.
