Product review (5 stars): PIck This One;  Yes you are capable of doing it yourself.
The package was received quickly.  Packaged well.  This product does not come with directions on how to replace the hose on your dishwasher.  I wouldnt expect it to include directions but I thought I would add that just in case another person was wondering.
So you are wondering if you can replace your hose unicouple thingy?  Are you willing to risk the $$??
My honest answer is YES!!  You can replace it.  I am a single mom, working full time with no family around. If I can figure it out so can you.  Your best bet (IMO) is to youtube a video that walks you through how to change this.  The you tube video was found by searching "How to change the hose thingy on a GE washer yourself".  Ha This product is the cheapest I have found to purchase

PROs:
* Cheaper than hiring a repair man and worth the risk of the price.
*Cheaper than ordering directly from the manufacturer.
*Worth the risk of the price because a new portable dishwasher is almost $500 dollars and I cant afford that or the time to hand was all the dishes. Aint nobody got time for that. lol
*Was able to quickly fix it under an hour.
* Quality of the product was the same or better that the factory part on the dishwasher.
*The hose does look cheap or ghetto
*The couple fits tight and does not leak.

Cons:
You do need some tools to change the part and you cannot replace it without the tools
*I believe taking apart the back of the dishwasher and replacing it was a pain more than changing the actual hose.
* You should have most of the tools that you need since they are somewhat common but be safe and google it or youtube it.

This was my first review of a product.  No, I did NOT get it for a discount.  I just want to help others out especially to encourage single moms, women, and for people who need a nudge that they CAN do this and feel comfortable buying a product because there are honest reviews.

Let me know if I should add anything else or if you want pictures. :)
Now order this and get it done! :)
