This is a F&P (Fisher & Phaykel, NZ brand) dishwasher arm part
This is the part the arm fits onto. Notice the white washer, its Teflon, its a bearing surface for the spinning arm
What happens with these items, the arm spins on the Teflon surface, it then wears thru it. It then starts wearing out the stainless steel arm at the same bearing surface.
One day, days from now, it will wear thru the stainless arm & then the arm will drop down, letting all the water out & the dishes will not get washed properly.
Thats when the owner throws it out....
Thats when you come along, unscrew the old parts & replace them with undamaged parts & sell it for Hundred$$$$
To check the arm, just grab the end of it & see how much 'slop' there is in it. The worn ones are wayyyyy more looser.
Bottom arms wear first, more water pressure on them. The top arms are normally good in a old washer, check the Teflon washer too.
