Extended warranties are usually very inexpensive and can save you thousands in the future. Some can even cover extra costs that result, such as cost of food that spoils when your fridge dies. It's simple and inexpensive to purchase extended warranties and one of the smartest ways to protect your investment.

Appliances can be large, heavy, and expensive and you probably don't have the special tools or expertise needed to fix them in a crisis. If you can spare a few thousand dollars without batting an eyelash for new appliances should they break tomorrow, don't buy a warranty. But if you're like most of us, protect yourself by purchasing inexpensive extended warranties when you buy a new product and save yourself big money in the long run.

Professional delivery and installation is available for every product we sell. We would be happy to coordinate delivery and installation for you.

2x broken in less than 6 months.

Submitted by Daddy of 8 - 10/13/2020

I know we're hard on things in my house of 10, but to leave us without a dishwasher 2x in less than 6 months because of repairs is pretty sad.

Submitted by PineAire - 9/26/2020

After living with such a noisy dishwasher-it must have been at least 85-99 decibels-this dishwasher is so quiet at 50 decibels. And I love the all white surface with the hidden operational features. I am pleased!

Submitted by ClassicCheryl - 8/14/2020

"There's a kind of hush" as an old 1960's British rock song begins that our kitchen has never heard. This GE beauty replaces a MagicChef that finally surrendered after almost 30 years. It was so loud the last couple of years that it sounded like the old Concorde supersonic jet taking off. ( I've experience that one ) The new white/stainless GE is as silent as a submarine.

Mixed feelings

Submitted by dd1219 - 7/26/2020

I like the features of the dishwasher, especially the automatic dirt sensor. I don't like the way the interior is designed, because the tines on the racks are arranged in a weird position, and my dishes don't stay in place. Also, it's a little bit complicated to figure out what all the lights and beeping mean. I like that it is very quiet.

Pleased with all the options for cleaning. Dishes ,pots, pans, go in unrinsed, come out like new,,, No more hand washing left over residue. Also, the dishwasher doesn't have that stale scent to it, nor the dishes... And we have a GE kitchen, laundry room. No other brand of appliance accepted in our home. Love my GE dishwasher and appliances...

Submitted by Page 1vp - 4/21/2020

Once the dishwasher got installed it has been great! I love how quiet it is and it seems to hold a lot more than my old Kitchen Aid that I had for 15 years, I hope this one lasts as long. I cook 3 meals a day for 2 of us and only have to run it every 2-3 days. I would have given it 5 stars, but the tines do not fold down on either rack. So far that has not been an issue, but it would be nice to have the flexibility.

beautiful and QUIET

Submitted by Terry 68 - 4/10/2020

I replaced a 15 year old GE dishwasher with a sound rating of 68 decibels, installed this new GDT645SGNWW and it has a 48 decibels rating. Unbelievable how much quieter this new one is. Since I am not a regular installer, just a home owner, I did run into a few obstacles, but I was able to over come them and got the unit working. I strongly recommend using a flexible water supply line and make sure you get the proper (required) 90° elbow to install to the unit (looks like a female garden hose connector on one end and 3/8" male on the other end). You can purchase the supply line with the elbow as a set, but there are other types of elbows and they will not work.

Submitted by Msdmd5 - 3/14/2020

This replaced an almost 20 year old Ge dishwasher that had been a good dishwasher, but it stopped working. It is unbelievable how much quieter this dishwasher is, I barely know it's running. I've used it every day with our family of 5, and our dishes have been squeaky clean. The stainless inside and top buttons are a huge step up from our previous model.

I have had no problems with the dishwash its self, but I had enormous problems with delivery. I ordered dishwasher in October 2019 and it wasn't delivered and installed until December 28, 2019. As said at the beginning, no problems with dishwasher. I like that the controls are on top of door. Keeps "little" fingers from playing with controls. Very quiet and easy to use.

Nice features and quiet

Submitted by HappyXX - 8/30/2019

We have had our dishwasher for a week and have used it 3 times. We found the detergent pods/packets are best. It's very quiet 48dBA compared to our old unit 57dBA. We have a great room with the kitchen off of it. We never have to turn up the volume on the TV like we used to do with the old dishwasher. Dishes come out super clean and glasses are spotless. We do use Finish Rinse Aid and we air dry. The top controls are easy to use and we like the ability to wash either the upper or lower rack when the dishwasher is not full. A Normal cycle is 80 minutes which is we use. There's a short audible tone when the cycle completes and the door light changes from amber to white. Our unit was purchased through HomeDepot and we used their delivery and installation services. Everything was completed quickly and efficiently by the installers. They tested to make sure there were no leaks and we have not seen any. Overall very satisfied with the purchase, installation and the dishwasher.
