Q & As


Bosch HMT75M451B Microwave Oven, Brushed Steel 3.6 5 32 32
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
Disappointed We bought this microwave as we generally buy Bosch appliances however, have been disappointed. The microwave moves backwards when you press the door release button which means you have to hold it with one hand every time you open the door. This means lots of finger marks over the (not brushed) stainless steel! Also, have discovered larger dinner plates do not fit in. 20 March 2013
Stopped working after only 3 years This Microwave worked perfectly and wasn't used heavily, but then suddenly stopped working after just 3 years. The light was on, the plate rotated, but the heat ceased coming! A real shame as we'd have expected better longevity from a Bosch product. We've now bought a Panasonic from JL instead which will hopefully outlive the Bosch! 20 January 2013
Smoking microwave Our microwave failed just now after only 2 years. It overheated and smoked from the rear panels and almost caught fire! This was suprising as it was a Bosch product. Probably get an extended warranty next time. 16 January 2013
