Disappointing Microwave Power – Not What You'd Expect from Bosch. My wife and I invested significantly in a full Bosch stack for our new home, fully expecting the same outstanding quality we've experienced with our Bosch/Siemens dishwasher and Siemens fridge (both five-star products). Unfortunately, the microwave has been a real letdown. The… Read more
maximum power output of 900W — even on the boost setting — feels completely outdated. For context, entry-level microwaves from budget retailers offer comparable or better wattage. For a premium appliance at this price point, it's simply not good enough.
To be clear, we're passionate home cooks and invested in the full stack: two ovens, an air fryer, and a plate warming drawer. Every other appliance performs brilliantly. The microwave, however, feels like an afterthought.
Visually, the stack looks stunning. But aesthetics only go so far. We're now seriously considering having the microwave removed and either replacing it with a quality black glass unit to replace it or relocating our 1200W portable microwave to the butler's pantry.
For those entering retirement and wanting the best — as we are — I'd strongly recommend researching the microwave wattage carefully before committing to this setup.
Would not recommend the microwave at over $2,600. The rest of the Bosch range is excellent.
Poor design leading to rust – Although the inside of the oven is protected with a coating, it seems that the microwave 'glass' in the top of the oven is only attached with 3 screws and retaining plates, being of poor quality, so that they rust and also leave a weak point for the coating as well. So now the oven has 3 rusted holes inside it. No help from warranty repair/replace despite obvious product/design defect Show details
Lousy product! – Worked less than 2 years after installation in Jan 2023. Expensive oven but it was the size I wanted. Unfortunately I had delays with my kitchen reno, so it was a few years before I had it installed by an electrician. I even called AppliancesOnline to check if I could return it a couple years after I bought it, but they told me there would be… Read more
costs to do that. The Bosch service person blamed cockroaches and small ventilation holes for the EO511 fault, but I cleaned it every week at least and the oven vents to the front for a few minutes after use and I often kept it open afterwards and gave it a wipe over to prevent grime build up. Just giving excuses for a lousy product. Quoted price of Bosch repair - $770. Out of everything I have done in my kitchen reno, buying this product is what I regret most.
Avoid at all costs. This product is a lemon!!! – Wish I had read reviews before buying this oven. I bought this oven recently and installed it in my brand new home. It's never worked from day one. The touch screen doesn't work. I contacted Bosch who told me this is a known issue with this model. Why is Bosch selling products with known issues? This is a recent purchase. The front panel was… Read more
replaced to fix the touch screen and the new touch screen also broken. Will not work at all. Zero customer support to resolve this issue. It's an absolute disgrace and I'll never buy another Bosch product again.

Avoid - unless you want to be driven mad! – It may actually work well, but as the thing is so complex to operate we may never know. Badly written instructions booklet is unclear and confused. The much-vaunted control ring is a joke; like something found on an ancient videotape recorder. It sometimes works… and sometimes it doesn't. Tip: try slightly wetting your finger before using.… Read more
Frankly, I will probably never buy a Bosch appliance again. This piece of over-complex nonsense has destroyed my faith in a once excellent brand.

Only had it a week and its throwing error code E6200 as per other reviews – Purchased it for our new home along with a matching Pyro oven. The oven works ok, but the combi microwave stops and throws error E6200 after 1 minute.... As a microwave when it works its sub par. The temperature it uses is very low and you need to double the time it would normally take to cook or heat anything. Show details

Microwave/oven - wall insert type - – Appliance no longer functions & will not even boil water in a test. Appliance is " arcing" from the tray to chrome plated grill insert at oven back. Unit is over 4 years old & has not been used much. Repair options are very expensive May end up having to be replaced. Poor end possibly for an expensive product Show details

Piece of trash – Microwave function is near useless. $2500 microwave and we still use the $200 Panasonic in the garage. Pretty much double any time any recipe calls and don’t even think about some sneaky popcorn. Update: Bosch sent a tech out and replaced magnetron. Same garbage. Can’t cook popcorn and takes forever to cook anything. Show details

If buying a Bosch wall oven be sure to buy the self cleaning option – My oven turns out as new every time I clean it. Preparation time before using the function is minimal ( you just need to remove all internal racks) and the results are outstanding. I'm so glad I didn't listen to the salesman who attempted to talk me out of buying the self cleaning option Show details · 1
Broken from day 1 – Error code E6200 from initial start up. Bosch refuse to replace as it is a "repairable" problem. Now have to wait for the parts to arrive from overseas. Ridiculous for a brand new appliance. Terrible customer service, not helpful at all. I didn't buy a brand new product for it to be faulty and have its parts replaced. LEMON Show details
Hi Jo V, Thanks for your review, we… Read more
I would give 5 starts if the cooling fan and the beeps were quieter! – It's so good having a single unit doing both microwave oven and anything that a normal electric oven does while saving cabinet space. However the fan is noisy and annoying, I bought BOSCH ovens exactly for quietness but the combination oven has something poorly engineered on it. I also have a Serie 8 HBG633BS1A Built-in Oven and you can't barely… Read more
hear the fan in any condition even under high temperatures - and this is my reference, both ovens are "Series 8" so you expect both having similar performance, specially the specs are nearly identical between both ovens.
We also found the beeps at the end of heating cycle too loud. It beeps 5 times LOUD. There are so many different options at the LCD menu, would be great to have the ability to reduce/increase the beep volume.
The drying fan also stays on too long after using the microwave, simply a waste of energy. If you heat milk for example for 30 seconds it drying fan stays on for minutes...No idea why, if there is no steam why waste energy with that silly fan? There is a option to reduce the "drying time" but it is not enough.
The positive side is, the normal electric oven is great (apart from the noisy fan!) it cooks evenly and the temperature control is also very good.
If I would recommend it? Hummm maybe not. BOSCH should release a firmware update and fix these little issues first. I'd look for a different brand until they give us the option to adjust what really matters.
The Best – We have this microwave oven combination. Which as the name suggests is a microwave and an oven. We have it as well as the Bosch 60cm pyrolytic wall oven rather than a double oven. Cooks well, both microwave and oven features work well. Easy to use and and navigate the features. It is the most frequently used appliance in our kitchen. Looks great… Read more · 1
and prevents us from wastingbspave having a delegate microwave.
Definitely recommend this microwave oven combo!
