Q & As

Bosch HMT75M451B Microwave Oven, Brushed Steel 3.5 5 35 35
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
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many reviews on this site highlighting exactly this issue and we are concerned that neither John Lewis nor Bosch have withdrawn this product from sale while this is investigated.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
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
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
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
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
Dangerous Fault Unfortunately like several other reviewers' comments, after only 3 years this product started to heat on its own which was a bit scary. Bosch recommended buying another product. Sadly it won't be a Bosch this time. It's a shame because it is a very nice looking product. 04 April 2013
Not bad while it worked - dangerous when it didn't I buy Bosch because of the quality of their products. This microwave looks good and does the basics. I mainly used it for defrosting - which it was ok at, though patchy with some parts rather too hot and others still frozen - and heating drinks and vegetables, which it did fine. Compared to other decent quality microwaves it is quite loud. It came with a 2 year warranty/guarantee. Two years thee weeks after purchase, it stopped functioning, and in a dangerous way. The microwave came on at full power whenever the door was closed - without being set to do so. The light didn't come on, nor did the turntable move. It is fortunate that it is noisy otherwise it might not have been noticed. I have replaced it with a Panasonic which costs £10.00 more, seems to be better quality, better features and, according to Which?, better performance - by some way. It is also quieter. Mine is the third one that has been reported on this site that has developed this problem - the others after about two years as well. I would avoid this product. It clearly has a fault and is potentially dangerous. 21 March 2013
