Product review (5 stars): Used to successfully replace broken Miele Dishwasher intake solenoid valve
I purchased this to replace a broken water inlet solenoid valve for a Miele Dishwasher.  The Miele inlet solenoid valve isn't attached to the dishwasher on our model; it is under the sink connected to the dishwasher with a hose.  This makes access and replacement easy.  The mechanical configuration of this product is different from the original, however, this seems to work just as well. Miele sells their replacement part for about $130 so there are big cost savings by using this third-party replacement.  There are instructions, including several youtube videos showing how to install 3rd party replacement solenoid valves for the original Miele part - search for these on the Internet.

I had to purchase a $5 adapter from our local hardware store for my installation and I also recommend Teflon pipe tape to make sure water doesn't leak where this product connects to the water inlet line.  I was able to reuse the hose that connected to the Meile solenoid valve. I soldered the wired connectors to the electrical leads of the Fridigdare inlet valve then covered them with electrical tape (or you could use heat shrink tubing).  There is no polarity to those connectors as an AC current is delivered to the solenoid valve.  I suspect you could skip the soldering iron step if you connect the wires (that originally connected to the Miele inlet valve) to the Frigidaire part using an appropriate crimp/fastener that any hardware store or auto supply store should sell.

Make sure you unplug the dishwasher and turn off the water supply before doing any of your own repair work.

The Miele part, and this part (when working properly), both make a soft humming sound when the solenoid is engaged and water is flowing through the valve. There is a slight vibration when you touch the plastic housings. If your Miele dishwasher's intake solenoid valve isn't vibrating or making that humming sound, and the intake water light is showing an error then there is a good chance this product can save you some money.

Our Miele's solenoid valve first gave out last February (it is now October) and I 'fixed' it by (first removing water line connectors then) soaking in vinegar; that gave me about 7+ months of additional use.  Vinegar soaking didn't help me this time and I had to replace the valve.

Good luck.
