Had a suite of Siemens ovens and warming drawer installed in new kitchen in 2017. The microwave function died in 2019 and was repaired under warranty.....eventually.
Microwave function died again in December 2020 and had difficulty getting Siemens to respond while they contemplated their strategy eventually deciding late January after repeated phone calls to replace the unit but with the replacement being the current model with a different appearance which would spoil our suite.
Accepted their offer of also replacing the pyrolytic oven at a discount but have not heard from them in the last 2 weeks.
2 months and still no resolution equals very poor service in my mind

This is the first steam oven I have owned and I am really liking some of the features available. I have used the steam function many times steaming veggies, fish, dumplings and more. When reheating food I have found adding the steam doesn't dry the food out. I have yet to use some of the options on the menu (there are lots to choose from) but have mostly been successful with what I have tried, there are times I have needed to extend the cooking but that hasn't been anything too major. Anytime when using the steam function you do need to use the drying function afterwards, nothing too major but something to be mindful of. This is a smaller oven so I also like that don't have to heat a large oven for small items.

Submitting my review after 6 months of usage.

Pros
Cooking is always even with useful functions and many menu options to choose from.
Rapid heat is being extremely useful and used most of the times.
Steam cooking is awesome.

Cons
App not available in Australian app store
Racks and rails are not dishwasher safe

I have used this oven for over three years and can honestly say it is the worst oven I have ever had. The oven is uneven, I just cooked a batch of fairy cakes and the front row were undercooked while the bag row were bordering on burnt. There is only one oven tray which means I have to cook the cakes in batches. There are a pile of big clunky metal trays which came with the oven which sit in the bottom of the oven and take up space. I did ring up to try to buy a new tray but it was prohibitively expensive. Very unhappy with this oven.

The oven has many highlights. Love how quickly the oven preheats. Food is heated and cooked evenly. The design of the oven fits in perfectly with the appliances around it. It is easy to keep clean.

This oven looks so stylish and modern. It is so easy to use, cooks to perfection. It’s easy to keep clean and easy to operate. I would say this is the best Oven I have ever owned. I also purchased the combination Oven which is equally as good. So pleased I chose the Siemens brand.

LOVE my steamer - we got rid of the microwave because we didn't have the room but also don't like the idea of microwaves. We can do EVERYTHING with this steamer - defrost or reheat food and steam baby food so easily and quickly.

The oven works very well cooks to perfection, controls are easy to use the 4D mode is excellent. A few crumbs have fallen between the door panels and we are finding it impossible to remove the door panels to clean. We followed the instructions in the book but still cannot remove the panels.

No totally disgusted with oven which keeps giving trouble service pathetic .... biggest mistake purchasing this oven !..... the computer front battle had broken down twice ..... to get some sought of service is absolutely impossible ... I blame Siemens and winnings for this lack of care .... could not make up my mind if I should purchase a Miele or this one A HUGE mistake .....

This oven is a marvel. My wife adores the simple interface and the speed with which it can reach the desired heat. It is all digital and an easy touch usability. The 4D mode is something I have not seen in an oven before and I would certainly recommend it for anyone. Very happy with this model.

I gave a 3 review only due to the ovens I purchased cook well. I purchased HB 673GOS1A and HR 676G8S2A My issue is the inside of both ovens mark , it is almost impossible to remove the marks. The self cleaning function is noisy has a very strong odour and does not clean. I have taken care when using the oven lining the trays yet it still comes out with marks. I have brought cleaners suggested by the Siemens representative when attending a cooking demonstration , unfortunately they did not help. My trays look like they are old yet only installed in December 2017. I would appreciate if I could be given a contact to take this further.

I normally read Product Review to make a general assumption on a product and I find there are SO many bad reviews and not many good reviews. My motto has always been, give credit when credits due! I have had my oven for 2 years now...it gets used daily. I absolutely love it. I'm still learning all the functions on it. But the cooking is even, the telescopic rails are so helpful and the meal plans are great! Siemens are such a fine product without the Miele pricetag.

Recently we remodelled our kitchen and chose Siemens appliances . I brought the pigeon pair oven and also the combination steam oven. I am in love with both. This review is for the oven model listed above. The best feature in my opinion is the self clean option. This is the first oven I have owned with this feature and I have to say that I am now spoilt for life. The double glass doors mean no more scorched fingers or radiant heat loss into the kitchen area. Great in summer. There are 13 heat selections to choose from which means perfect food every time. Ultra sleek design. Easy to use. Heats up super quick
