Siemens SN25M831GB 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


Siemens SN25M831GB Dishwasher, Stainless Steel 4.4 5 32 32
O K so far but i have only had this dishwasher for a few weeks so i am still on a leaning curve. My old Siemen lasted years and gave great service. My first impressions of this model are not quite as good. i have found that on some of the cycles plates do come out with a stale egg smell even though no egg plates have been washed. This could be part of my learning curve. 08 July 2014
Siemens SN25M831GB Dishwasher, Stainless Steel Very pleased with the product. It looks like a dishwasher, acts like a dishwasher and sounds like a dishwasher. 08 July 2014
disappointing appearance we love to match our steel look appliances but when opened surprised and disappointed to see a golden dishwasher which even kids dont like. still shocked what to do as order for the same day of plumber,s appointment as its fixed but not used .also missing salt funnel. 04 July 2014
Very Happy with this dishwasher Looks great and washes dishes very well. Love the cutlery tray - it slides left and right and so makes it easy to fill with plates. Large load and I'd say very quiet and easy to use. 04 June 2014
Cooking for 8 people most nights Very quiet,great if in an entertaining kitchen,stylish, remember to peel the protective plastic off,trays have higher or lower settings for higher plates,I only need to use the quick 33 min wash as it cleans and drys sufficiently, accidentally put it on a longer wash and there was no difference in performance, haven't used it to wash pans yet because the cycle seems too long so quicker to wash them myself, very very pleased so far and would definitely recommend this one as over the past 28 years I have had about 5 dish washers and this is probably one of the best. 19 March 2014
Just what I needed! So far no problems and it is very quiet! It washes really well on the half hour cycle - even bowls that have been there overnight. 14 January 2014
A perfect performer This is an excellent machine. It's quiet, very effective at cleaning, tardis-like in its ability to swallow far more dirty crockery than its predecessor, a dire Indesit, which was only one year old at its replacement. I had hoped the Siemens would be a bit better, but I have to say it's light years ahead. The clever interior layout, with a number of adjustable racks, means I'm putting it on every two days, rather than the predecessor's one. Highly recommended. 10 December 2013
Clean Dishes Looks great. Very quiet operation. Cleans extremely well. It does exactly what a dishwasher should do. 12 November 2013
