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. Please consult a sales associate about delivery options.

More every day

Submitted by Stasia901 - 2/25/2019

We added the Bosch Steam Oven into the design of our kitchen and couldn't be happier. Initally, I was concerned about the size of the oven being too small. Ive been surprised how well everything fits in the space. I'm still learning how to cook various things in it but we have used it on a daily basis. Great product.... Happy user.

Healthy way to cook

Submitted by Steamer - 12/13/2018

I bought this for a remodel to replace the microwave. Healthy way to cook but I have had to have it replaced because the clock did not sync with the oven clock and during servicing the unit was scratched. It went off 6 minutes over a month. Eggs cook perfectly and broccoli was green and not over cooked if the suggested time was used. Sweet potatoes cook moistly. There is a learning curve. I wish the door did not open down but Right to left or vice versus because it hard to reach the back to wipe for shorter people.

Remarkable appliance!

Submitted by Nikki17 - 12/11/2018

We own the Bosch steam oven for 6 months and have been learning how to use it. At Thanksgiving we took a chance and cooked a 13 lb turkey in the steam oven following the Bosch instruction booklet. The turkey cooked in 75 minutes (!!!) and had crispy skin and juicy tender meat. We had a former professional chef with us and he was as amazed and pleased with the results as we were! The reheat function is fantastic... it warms the food, reconstitutes it to perfect texture, unlike the microwave, and gets things appropriately crispy. We reheated our leftover cornbread stuffing and turkey and it was PERFECT. This oven dramatically cuts down cooking time so you can throw a last minute meal together for surprise guests and cook something quickly and it's delicious. I just used the plate warm function the other day and they were very warm but could still be handled without a mit. We are still learning how to use all the functions but we are so glad we purchased this oven. I only wish there were more cookbooks / recipes / instructions for this technology so we could really learn the ins and outs, because I'm guessing how to adjust my recipes' cook times

LOVE LOVE LOVE this oven

Submitted by DALM - 12/11/2018

Cooking with steam is amazing. Not only does it keep food moist, but the "reheat" feature is fabulous as well. It took a few weeks to get used to using the oven but now I'm hooked. I also like the fact that you don't have to use steam -- there's a "European Convection" feature so if I'm just making a piece of fish for two of us, I don't have to heat up the big oven. Wonderful appliance, I'm so glad we invested in this.

So many issues

Submitted by Seth - 4/19/2018

We have had this for three years. It's mostly been a bad purchase. 1) how often are you really going to try and stream stuff? If not often, get a real oven. 2) it's a bad oven. Cooks the heck out of stuff near the back. And it's such a small oven relative to the space it occupies. 3) the descale requests are constant - see other reviews - and getting through the descale process is difficult - often requires several tries. 4) it's impossivle to keep clean. It does have a "clean" setting but whereas your real oven gets like 600 degrees and burns everything until it's gone, this oven tries to steam all the grime away very unsuccessfully. Be ready to scrub this thing. 5) we've had lots of problems. Mostly related to the steam function (which is the whole point of this thing!). the oven vents out steam just above the handle. The moisture then gets inside the control panel and the entire thing freaks out because moisture is inside the buttons. We've been through a couple control panels - not cheap. If I were to do it again, I'd just buy a regular oven and deal with steaming my veggies on the stove.

Issues with Descale upon install

Submitted by KimF - 12/11/2017

I love this steam oven when I could get it to work. I have had nothing but trouble immediately out of the box with the unit asking for descaling. I was able to get around that by restting the breaker. Now the unit is totally locked in descale setting with the control unresponsive & will no longer rest with the breaker. Now the unit is out of warranty. What a waste of $$$$. Bosch is useless for there defective products. Check the reviews on gardenweb

Great Purchase!

Submitted by Joanne1 - 7/10/2017

I bought all Bosch appliances for my new home and this was the highlight of my kitchen. My first meal was a baked chicken and it was absolutely wonderful. I was surprised how clean the oven was afterwards and the minimal residue was easily wiped out with a sponge. You cannot go wrong with this oven. It is definitely worthwhile to review the literature with the oven and watch a few of the videos.

Some quirkiness with descaling

Submitted by DavesOven - 6/21/2017

I love the way this oven cooks. I have had consistently good luck experimenting with recipes. But there is some quirkiness with the descale cycle. The oven immediately requested descaling after installation which didn't seem right. In the middle of the descale cycle, you have to change to water, but you only have 30 seconds to do so. If you aren't quick enough, you have to repeat the descaling process.

Not your average oven!

Submitted by jbmpls - 6/7/2017

We bought this oven as part of our new build. We had heard steam ovens are great for retaining the nutrients of food and wanted to try it. It took a while to get the cooking correct, time and temperatures needed can be much different. Through trial and error, we are on good footing now. It looks so good with our built in microwave.

Good and not so good

Submitted by Sierra - 12/13/2016

It steams well, but I haven't had much luck with the steam/convection combo. For some reason it stops and resets when it's in this mode. Have had a service person check it out, but they say it's ok.

Special features for our new kitchen!

Submitted by FelixtheCat - 12/13/2016

This was a tough decision, but I am so glad we decided on this steam oven, over a microwave or a speed oven. We subscribe to a CSA and having the steam oven makes it easier for us to steam all the great veggies, keeping their color and nutrients in tact! It also makes perfect soft or hard "boiled' eggs, and comes in handy when you need an extra oven to fit in another tray of cookies, reheat, or keep other dishes warm. Reheating pasta is amazing, it is almost better than when it first came out of the pot! The oven heats up super fast too and it is really cool to turn the light on and see the steam in action! Cleaning/or drying it after steaming is more labor intensive then expected but having all of these features is well worth it.

This steam oven has real problems

Submitted by LgHuggins - 12/12/2016

I purchased this steam about 2 years ago, we have had the repair technicians out more than a dozen times and Bosch has replaced it once and it is still not working correctly. There is a design flaw that allows steam to get to the control board and after some time with it exposed to steam it starts behaving erratically (turning off when it wants to, changing from steam convect to defrost .....). I have asked Bosch again to replace or refund on this and still waiting for the "supervisor" to review. To be fair to steam ovens I LOVE cooking with steam but not with this oven.

Great oven

Submitted by Pinklady27 - 12/12/2016

I use the convection part of this oven all the time to cook for just the two of us. Being small it heats up in no time and cooks super quick. The steam part is great on vegetables and left overs and so much healthier than the microwave I do wish that the door opened to the side - it would be much easier to get things in and out and to clean.

Great oven!

Submitted by Padpadman - 11/5/2016

We moved into our new house with a fully equipped contemporary kitchen three months ago. It turns out this appliance is the one we used the most. The only draw back is cleaning. Little tip: After cooking, run the oven in Europ Convection mode for 7 min. to dry out the oven interior. I just use distil water to generate steam and leave the water tank in all the time which means the interior water reservoir is full all the time. This will prevent the reservoir dry out and develop stain spots. Give the interior a good clean with the steam clean and descale sysle, it is as new.

It's the simple things

Submitted by Psegor - 10/29/2015

I really like the sleek look of my oven. I've steamed vegetables with ease and freed up my cooktop. The display guid helps with the intimidation factor of cooking with a steam oven for the first time. And it's a small thing but I love the feature of the oven timer shutting off when you open the oven door. I'm working up to trying a roast. Over all I'm really excited with my new stove.

Just finished cooking my first chicken breast in this awesome oven and it was a complete hit with my family. REALLY moist with a crunchy skin. Also, easiest meal to cook and clean up after. Just got the oven and have found it very intuitive to use.
