Product review (5 stars): Dishwasher was not filling with water - This fixed it!!
My 15+ year old dishwasher suddenly stopped filling with water. It would run through all the phases, minus any water. Checked the hoses and hot water supply and everything was fine, so a little googling and I find out it's likely the Water Valve. For ~$25 for the part, it was worth purchasing to see if this fixed my problem.

It definitely did!! Found some youtube videos with step by step instructions on how to replace this part, which was fairly easy. After it was installed, the dishwasher began working like normal! Success!

Part arrived within 2 days (Amazon Prime) and appears to be a brand new part. It did not include the 90 degree copper "elbow" that connects the hot water hose to the valve, but I was able to remove this from the old part, so I didn't have to buy a new one.

Much cheaper than replacing the dishwasher or having a repairman come out and fix it for me.
