Oven door exploded all over my kitchen glass fragments earlier. My litle westie was in the kitchen he is a bag of nerves now won't go into kitchen . Terrible this could cause a serious accident .never buy Siemans again.

I have the HB78AB.70B model. I must say Im seriously disappointed with this product. Its imposs to see food under the grill as the black painted glass at top of door is so thick it covers the top grill area so you cant see when stuff is cooked/brown. The pyroclean is a disaster....all it does is evaporate any built up grease inside the oven and, as theres no filter, blows it all round my kitchen settling on cupboards, paint and furniture. The whole room fills with choking smoke and grease particulates. Instead of cleaning an oven I have to clean the whole kitchen everytime I use pyroclean. This time the lights glass cover shattered. The area beyond the door seal doesn't get cleaned, the internal glass stains and the system doesnt allow you to leave the racking in place, so they still have to be cleaned manually.For an expensive oven this is poor design, AND if you have a problem even in-guarantee period they say they still charge you to send an engineer out.!!! Think again"

I have faced the same problem the glass of the Siemens oven has exploded during auto-cleaning. And Siemens has rejected to replace the oven or glass.

As per the previous review, I too experienced the exploding outer glass panel during a standard cleaning cycle with the Siemens HB750550B model. Exactly the same scenario. It was lucky that nobody was in the kitchen at the time or they would have been seriously burned by the red hot shower of glass fragments. As it it, my cupboards have been damaged (red-hot glass shards have melted the finish) - it could so easily have resulted in serious injury

I will never use the self-cleaning function again - it's potentially lethal!!

As for Siemens - Never again! Our other Siemens appliances have not stood up well to normal (family) daily use. poorly manufactured plastic knobs were the first items to show immediate wear. For the price we paid, we expected much better quality and longevity.
