Siemens SN25M831GB Freestanding Dishwasher, Stainless Steel

Product information

No more grubby fingerprints! The Siemens SN25M831GB dishwasher has been specially coated with a stainless steel-look lacquer to keep it looking both strikingly pristine.

Precision engineering has resulted in a ServoLock door on this unit, which allows the door to close virtually by itself and with minimum effort on your part. A child safety lock protects from scalding, and curious little fingers won’t be able to change the wash settings thanks to tamperproof controls!

More room and greater flexibility are the least you can expect with the SN25M831GB, thanks to its innovative VarioFlex basket system. This offers the flexibility of 6 foldable racks throughout the machine, while the 3-stage RackMatic system makes it easy to adjust the height of the upper basket, even when fully loaded. And it gets even easier to wash bulky items, with the large item spray head - simply remove the upper basket and attach the head.

This large capacity machine washes up to 12 place settings, using only 12L on its 50°C Economy programme. You are offered a choice of 5 programmes and 2 special options, including:


  • Pre-rinse
  • Intensive 70°C
  • Auto 45-65°C
  • Economy 50°C
  • Quick wash 45°C
  • varioSpeed; and
  • Half load.
  • The Siemens SN25M831GB runs extremely quietly at just 46dB and features a 1-to-24-hour time delay so you can set it to run just when it suits you.

Q & As

Rated 4.4 out of 5 by 43 reviewers.
Rated 5 out of 5 by Great product I was rather sad when my last dishwasher of ten year gave up the ghost but I am really pleased with my new replacement! Noisier than my last one which was a smeg but is a great asset in my kitchen and does a great job and looks brilliant a good item all round! 24 March 2015
Rated 5 out of 5 by 5 Stars for Siemens & JL Excellent machine, does what it says on the can...looks good & very quiet. First class service & price from JL. 17 February 2015
Rated 5 out of 5 by simply outstanding excellent machine that does its job really well really good build quality 17 February 2015
Rated 4 out of 5 by siemens dishwasher pleased with this so far,,does a good job, quick wash is quick and cleans all dishes well- doesnt dry everything as well as my old one but no complaints...dont forget to take the plastic green protective cover off tho,, 17 February 2015
Rated 4 out of 5 by Great dishwasher Had our last Siemans dishwasher for 10 years, so thought we would stay with what we know. Not disappointed at all, cleans very well although thought it would be quieter. Hope it lasts as long as the old one. 03 February 2015
Rated 5 out of 5 by Perfect Really pleased with this dishwasher. Happy with the layout and the quick wash is great. It is really quiet and like that it switches itself off at end of wash. Happy with the stainless steel finish and fits in well with my other appliances. Would recommend it. 03 February 2015
Rated 1 out of 5 by Very dIsappointing I have been thoroughly disappointed by this dishwasher. The design of its interior is crummy, as it can only take a small number of dinner plates in addition to the cutlery basket. The plastic separators are not robust, and look cheaply made. Worse still, its ability to get dishes clean is really poor. I often have to put it on twice, as the first wash cycle merely results in spreading food onto a wider array of the loaded plates, cups, etc. I really wouln't recommend the product. On the plus side, the non-stain steel exterior is excellent - although it is a slightly darker colour than other steelware, as some commentators have remarked. I think it still looks smart. It's also very quiet. These two plus points don't go anywhere near outweighing its shoddy performance though! 27 January 2015
Rated 5 out of 5 by great Really pleased with this dishwasher. Replaced a Siemans, this is a far superior machine. A good choice of programmes and a digital display to show length of cycle. Dishes have emerged gleaming. I really like the industrial appearance of the stainless steel front... doesn't show fingerprints either! 16 December 2014
