Q & As

Rated 3.5 out of 5 by 37 reviewers.
Rated 4 out of 5 by Does the job and looks the part Quality product as expected from Bosch. Have been using this for about a month now, it is easy to use and and so far seems robust and reliable. Comes with mounting hardware for attaching to the underside of a cupboard to lift it off the work surface, but we just have ours on the counter. Looks good with the rest of the stainless steel appliances! Only negative - the microwave keeps beeping at the end of the cycle until you press the stop button or open the door. Some may like this feature but it can be annoying when you are not able to get back to the kitchen right away! 07 July 2015
Rated 1 out of 5 by Dangerous fault as reported by others I have no problem with John Lewis, but I feel compelled to leave a review about this microwave. Mine is about 5 years old but has just failed with the same fault as others have described; it started humming and the casing gets very hot, without being turned on! The only way to stop it is to open the door, but it starts to operate again, without the timer being set, as soon as the door is closed. Fortunately we were in the house when it failed. My recommendation is to avoid this product. 27 March 2015
Rated 5 out of 5 by Happy John Lewis customer Love my microwave. Easy to use, great looking & very functional. Very pleased, had helpful discussion with sales girl. 09 December 2014
Rated 2 out of 5 by Safety concerns about this product This microwave was reasonably reliable but has now started making a very loud buzzing sound when plugged in. We have serious worries about the possibility of it causing an electrical fire. There are too many reviews on this site highlighting exactly this issue and we are concerned that neither John Lewis nor Bosch have withdrawn this product from sale while this is investigated. We have now unplugged it and now feel we have to buy a new microwave (not a Bosch one) as we are too concerned about the safety issues. 27 September 2014
Rated 3 out of 5 by Built in obsolescence - further to the review below Ours just gave up three months after the 2 year guarantee finished. Again the worrying thing was not that it gave up and died (bad enough) but that it continued making a noise even though it was off. There was lots of evidence of heat being produced on the top when I took the cover off and would feel that there is wrong with the design if there are two examples of this sort here. The replacement microwave will not be a Bosch on. 17 September 2014
Rated 2 out of 5 by Excellent while it lasted but really concerned about ultimate safety of this product We bought this model over 4 years ago so from that point of view perhaps I shouldn't complain, but there is built-in obsolescence and then there is a machine that could potentially burn your house down if it fails and you don't notice in time. It was 18 hours after the microwave was last used that we noticed it was still cooking on a zero timer setting and that the sides were really hot - thank goodness we didn't have anything flammable nearby. We'll almost certainly be buying a new microwave from John Lewis but not a Bosch model - like other reviewers I'm really shocked that JL still stock a microwave that can mis-function so seriously. 10 July 2014
Rated 1 out of 5 by Another near accident Microwave has started cooking on full power with the door closed like other reviewers' microwaves. VERY dangerous. John Lewis, it's crucial you sort this out with Bosch. 25 November 2013
Rated 1 out of 5 by DANGEROUS APPLIANCE - FIRE HAZZARD! I am amazed JL still sell this after the number of reviewers describing the same dangerous fault. My microwave is approx. 3 years old and has developed the ability to cook on full power as soon as the door is closed. The first time it did this I heard the timer ring to say cooking complete but it wasn't until I heard a bang as food exploded did I realise it was still cooking the food! after which each time I closed the door it started to cook again. I also noticed that the top of the microwave was extremely hot, (total time cooking = 2mins). PLEASE, PLEASE JL feedback to Bosch before one of these microwaves starts a house fire. 13 September 2013
