Product review (5 stars): Saved me money on my GE Portable Dishwasher
When I talked to GE, they said I'd need to replace the entire unicoupler, including the hoses.  That seemed silly, so I went hunting around online.  I found this, and it worked great for my GE Portable Dishwasher (Model number GSE3500N10BB).  The entire process took 2-3 minutes, including taking it out the box it was mailed in.  I was nervous it wouldn't work since it's a Whirlpool product and mine's a GE, but it fit perfectly. Big thanks!
