Q & As

Siemens SN25M280GB Dishwasher, White 4 5 17 17
Disappointed with machine, especially with top cutlery tray I really don't like the top tray for cleaning cutlery in this machine, even on intensive wash I find that cutlery cleaning is poor unless you have very little on the middle mugs tray and not great even then. Also the cutlery tray holders only hold thin tableware handles, not the fatter handles of kitchen knives. I have had to put the cutlery basket from my old machine in the bottom which works but takes space for plates. This top shelf also reduces height on the mugs shelf so bowls are a problem. As well as this the detergent holder is rather small for the all in one tablets and the book actually recommends that the machine works better with individual liquid or power and rinse aid rather than these modern tablets. Plate cleaning is mostly OK on intensive, haven't tried any other program as the book seems to say the automatic ones only work well if everything is equally soiled so sensor looking at water gets suitable result. As always John Lewis delivery service was very good. 19 August 2014
No better than a cheaper make or model Very quiet. Cuttlery tray is an improvement on a basket as utensils are separated and come out clean. However the contents of the dishwasher dont dry particularly well even using the 'extra dry' feature. It is also difficult to stack plates that have a lip and are thicker than a bone china type plate. When choosing a new dishwasher in the future I would take a plate with me and try it in the rack to make sure it fitted. 12 August 2014
So Quiet -Highly recommended This dishwasher bought to replace a Bosch that had given good service but had would run and run with a minute left to go. Can say that this is the quietest dishwasher I have ever come across. Like the cutlery drawer and am generally very impressed. Had a recent discussion with a whitegoods repair expert, and he suggested Siemens was a good choice and would have to agree with him. Highly recommended. Always go to John Lewis for purchases like this but wish delivery on whitegoods was quicker. Most people buy because their old machine has gone pop and they need to replace it immediately. Not so critical with a dishwasher but certainly a washing machine is a near daily need for most families - you need 'next day delivery' not in a week plus. 06 August 2014
Extremely disappointed Unlike other reviewers having had an AEG for the past 7 years I am extremely disappointed with this product. It is impossible to wash a dinner plate larger than 10.5 inches with the top tray down and raising the top tray then prevents you washing glasses taller than 5". Granted it is extremely quiet but a 3 hr.15 mins wash on eco!!?? FULL MARKS to John Lewis - having had this product for a couple of days we have today exchanged it without any hassle for another AEG (granted more expensive but will do all that we want having taken our plates and glasses with us to John Lewis to check) . My advice - take a glass and a large plate with you when you select your next machine. 31 July 2014
Not great Pretty much the same in performance as the Beko it replaces, cutlery draw doesn't clean as well as a basket so have removed the draw and used the basket from previous dishwasher. On the plus side this gives more room for the top basket, meaning you can put taller objects in even at the highest height setting. I only use 70 degree wash now as can't guarantee the vario or auto settings will get everything clean. Even on 70 degree it doesn't get rid of egg from bowls that has been soaked overnight beforehand, and also items near the edge of the dishwasher do not clean well. Extra racks at the back of the bottom drawer look like a good idea but haven't used them as that space is almost always used for big cooking pans/plates so they can't fold down anyway... The dishwasher was dropped whilst being delivered but was advised it is cosmetic so shouldn't affect performance. Overall not impressed, especially given the price. 29 July 2014
Very good indeed Okay, so I've only had the product for a month; but so far it's been outstanding. As per other reviewers comments, the first thing you notice is how very quiet it is. All the wash programmes do exactly what you might expect. It's only a dishwasher, but for a dishwasher, I can't recommend it highly enough. 22 July 2014
Another excellent buy from John Lewis Our 13-year old Miele dishwasher broke down and the cost of repairing it would have bought me two top of the range dishwashers, so I went on the hunt for a new one and settled for this. The cutlery drawer and 5-year guarantee were big factors in deciding on this Siemens dishwasher. Like other reviewers who have changed from Miele to Siemens, I had doubts about the build quality. The drawers seemed plasticy and clunkier in comparison and I wondered if I'd made a terrible mistake. Less than a week since delivery (which was a revelation compared to other firms# - the delivery men were polite, skilled, arrived on time and did a great job - huge thanks, John Lewis!), I am delighted with my purchase. This dishwasher is very roomy, efficicient and really quiet and it switches itself off when it has finished. It is very cleverly designed. I'm getting to grips with the various features, the latest thing being Delayed Start, which is marvellous. The results are sparkling clean china, pots and cutlery, even on Quick Wash and any doubts I had have evaporated. After weeks of enduring the misery of washing my own dishes #life's far too short for that!), like a scullery maid in Downton Abbey, it's brilliant to have a working dishwasher again and hopefully this Siemens machine will prove to be a great purchase in the long run. The kitchen is tidy, equilibrium has been restored in my household and all's well. If in doubt, buy one of these! 09 July 2014
Broken down twice in 4 months The only good thing to be said about this dishwasher is that it is very quiet. But in four months I have had to call out an engineer twice, and it has been out of use for a week each time. I would not have another and would not recommend it 09 April 2014
