Re: More shattering news!
What I don’t get is why Adrian Porter ( of Which?) suggests there has been a big increase in incidents of shattering glasses “in the last 18 months”….?
And….does the glass get made by the same manufacturer…. Pilkington or Dow for example?
I don’t hold any credence whatsoever to glass breaking as a result of scratches from belt buckles etc. Or that neither temperature nor vibration are a cause. What could be an issue however is the more recent style of glass that many manufacturers adopt. By placing a flattened shape at the top of the glass that is intended (apparently) for greater load and detergent distribution. Does that shape lessen its strength and durability I wonder?
Finally, where is Andy Trigg when you need him? 😉
Re: More shattering news!
The shape is designed to get the clothes back into the drum. So that’s not the reason and, if it were, we’d see loads of cases.
No, they don’t all come from the same suppliers.

Andy’s latest article in response to the press reports here:
http://www.washerhelp.co.uk/exploding-washing-machines.html
I have personally only come across one case, a 2007 Beko WMA510W about three years ago.
Re: More shattering news!
There was a thing on Jeremy Vine some time back about glass tables shattering rather explosively randomly, if I remember it comes do tension in the glass and minuscule imperfections.
Search Goole for random exploding glass, lots of stuff.
Perhaps It’s just down to this, glass can inherently just shatter.
Re: More shattering news!
Have seen many with score marks on the glass from drum scrapes also i’ve been to one that had a shattered door glass which I found what I thought had caused it to happen.
The pin securing the hinge was fitted incorrectly in manufacture & was on top of glass.
There still was part of the glass under the pin around edge of door when I dissasembled it. It would have caused stress on the glass on every opening & closing action & after a period of time it goes boom.Re: More shattering news!
I’ve seen loads of machines in the past with glass scratched as though the customer regularly loaded it with nails – they probably did. Never saw a glass break due to that though. Maybe the quality of glass has deteriorated very slightly from what it was in the past due to recycling and recycling and recycling and … whoops record got stuck. It is well known that you can only recycle stuff so many times before the impurities start to have an effect. Could be that the modern stuff is beginning to be just that little bit more brittle.
I’m sure the manufacturers will be taking this scare story very seriously (cue Philip Glass music) behind closed doors* (whilst denying any possibility of a problem publicly) and will be making sure that any neccessary adjustments to quality control are put in place.
I suspect this could also be true of the aluminium used for spiders but they probably won’t be too bothered about that.

Andy Trigg came up with this article so it would be interesting to learn of his findings.
I’ve written a new article trying to summarise everything in a balanced, responsible non sensationalist way. It’s understandable that media would find this worth reporting but they hadn’t picked up on the fact that the 53 incidents so far have been reported over 2 and a half years so it’s still presumably very rare. However, there have been 15 reports of the glass exploding when not even on, which adds a different dimension to the issue. Also, the second highest reports so far are on Miele washing machines so unless Miele have been caught out thinking they can get away with cost savings it sort of implies it’s not necessarily down to cheap rubbish machines alone.
Also, the cases have been reported since 2010 (not 2008) My original article about a washing machine door falling onto a tiled floor when a small child fell against it in 2008 started to attract exploding door glass comments in 2010
Re: More shattering news!
HMMM 50 out of how many appliances around.
More likely since the average appliance has traveled around 14,000 Kms before reaching a clients home, likely just been stressed at some point and since its safety glass and designed to “EXPLODE”, hell oven glasses have been doing it for yrs, i’ve probably changed around 20 for one brand this yr.
As for Miele, there as guilty of sourcing cheap components as every else, just ask Little Swan. :rotfl:

Oven glass is safety glass, shatters into nice blunt squares. As far as I’m aware though washing machine door glass is not, and shatters into very sharp shards.
Re: More shattering news!
Just a theory. It is possible that glass has under gone, during the manufacturing process, devitrification ( devit glass). This is were the normal molecular make up of glass which is a random structured lattice has become in part crystalline this is optically different to normal glass and mechanically different too! What might happen is the `fault`junctions between the two materials create glass mechanical strain and stress and it is possible (?) that the high vibration frequency on spin or after a spin may well cause the glass to pop. Sometimes this is analogous to ruby (crystalline as in gemstones) glass fracture filled material ( a lot of rubies are glass filled to improve their looks, in fact most are unless they cost a fortune)when in ultrasonic cleaning machines the two do sometimes shear apart or attempt to- I used to be a forensic gemmologist but that`s another story! Devit forms usually when the glass temperature is kept too high for too long and the glass is not cooled quickly enough so the glass mixture has time to cool to try to have a regular lattice i.e. more crystalline than amphorous glass, or too high a lime content, or dust/foreign material settling into the glass- a dirty casting mould in other words. Hope this helps.
Re: More shattering news!
I am sure washing machine door glass is safety glass, ie toughened (or tempered), much the same as a “Pyrex” dish, car windows, modern glass furniture panels, and as required by modern building regs in door glass and low level glazing.
The broken Beko door glass I replaced 3 years ago had broken into small cube-like pieces, not particularly sharp. My customer had “helpfully” left the pile of glass fragments for me to clear out of the drum and door seal.

There maybe some, but I have plenty of photos sent to me showing large dagger-like shards of glass and lots of small pointed shards.

Consider yourself now made aware. :boops:

Maybe that is where the issue is. 😉
