I just ordered the lower arm for my GE Triton Dishwasher, since the piece that comes out broke and now the dishes on the top are not getting clean. However, I cannot figure out how to remove the old and replace with the new.
Make: GE Triton Profile
Twisting it out.
Thanks for the question.
The bottom spray arm does unscrew from the part under the tub, it is sometimes a little difficult but it does unscrew, try using a belt wrench which you can buy at Home Depot.
