CANNOT BELIEVE THAT THIS HAS HAPPENED BEFORE!

This has just happened to us, on saturday morning, our washing machine got louder and louder making a 'thudding' noise, as my mum walked over to it asking whats that noise, and as it got much louder she pressed the power button and held it in and the power went off, then a massive bang! the glass exploded all over our floor even reaching the other end of the room and hitting the ceiling! luckily with only a couple of scratches on my arm, my mum wasnt hurt, but it was bad enough! the clothes inside are mostly ruined! BEKO said that if we have the reciept they can send a repair person to come and check the damage and the parts will be replaced but WE have to pay for the labour...surely this isnt our fault? what on earth can cause any washing machine to do this? We'd never seen anything like it, but when i started looking online, it became clear that this isnt too rare! ESPECIALLY as its the same model that ive heard about! If anyone has advice please reply!
