Product review (4 stars): Great Design, Excellent Cleaning
If you are in need an 18" dishwasher, you should seriously consider the GE Profile PDW1860NSS.  First, the smaller line of dishwashers are often priced pretty close to their full-size counterparts.  So unless you need an 18" model to do opening size or kitchen size constraints, you are better off looking at 24" models.  For me, the existing dishwasher getting replaced was 18" and I did not want to go into extra work to increase the size.  The GE Profile PDW1860NSS showed up on my list for its size, design, and cleaning ability.

The design is very modern and sleek.  There are no buttons on the front as they are all located on the top, hidden except when the door is open.  The front is a solid stainless steel exterior with a smooth handle on top.  It's sleek and blends in well.

As for performance, it has done an excellent job of getting just about everything clean.  It offers heavy duty, normal, and light cycles as well as other options.  It also shows you the time for each cycle.  I have yet to find anything not come out clean, so I'm very pleased with this unit.  I have not had any issues with it not having sufficient hot water.  Everything is clean and dry when the cycle is complete.

On the negative side our two small items.  One, when the dishwasher completes its cycle it beeps to tell you its done.  It then continues to beep every five or so minutes for 30-45 minutes.  Not a huge deal by any means, but then the power light stays on until you open turn the dishwasher off.  It doesn't bother me at all, but surely they could have found a way around that.  Second, the dishwashing soap container has gotten stuck once or twice if dishes are placed too close to it.  It's simply a small door that pops open automatically.  I often use tablets, so the tablet didn't full dissolve when that happened.  It's easily worked around since I know about it now, but could have been easily resolved when they designed it.

Overall, I'm very pleased with the PDW1860NSS 18" dishwasher.  Looking back, I would have still purchased this unit.  Well worth your consideration.
