The reason for these Diplomat oven inner glass doors failing maybe its just one of those things that just happens to oven sometimes. Besides the issue spilling hot glass in front of the oven.
I was just wondering whether people have checked the tightness of the screws directly under the glass sheet in the door when the door has shattered ?

As far as the person who says he’s never seen an injury as a result of this – well, that’s about to change.
Yes, ours exploded last night. It’s a Hygena Select 910. With the grill on top and convection oven on bottom. Steak was in the grill when it exploded. I wasn’t touching the door, I was about 2 feet away. But the grill is at eye level and I often look in to check on the food – never again.
The hot glass flew out with great velocity all over the kitchen. Some landed on my foot and I have a burn.

The glass also melted the vinyl floor.
Then, the sudden rush of cool air INTO the oven through the now-compromised seal caused a fire to ignite inside, which could have caused even more damage.
This is extremely dangerous. There could have been children or animals within the WIDE range of hot glass projectiles.

Hi, been reading this thread with some interest as we’ve had something similar just happen, although with the outer glass. We’ve got a ADP0150 and three weeks after installation the glass in the door (not the inner glass) shattered spontanteously.
Extra Care agreed to send another door said they had a policy of no compensation for the inconvenience (take away is obviously much more expensive than fishfingers and potato wedges). A bit miffed but with little other option I asked if the door was an easy replacement job I can do myself (rather than wait for the engineer and incur more cost).
The rep went away to check and came back with detailed instructions as to how to fit the door (which it turns out is incredibly straight forward – nothing more than 2 screws tbh) and told me I’d be fine to do it. I still booked an engineer though just in case.
After the door was delivered an engineer called to come and fit it(I hadn;t had chance to look at it myself) and as I wasn’t available when he planned to come I asked him if it was something I could fit myself. He agreed it was very straight forward and again gave me instructions as to how to do it.
Two days ago I went home and fitted the door as instructed (no offence to anyone on here but its not rocket science – my mum could do it – and I can strip/rebuild an engine; have fitted the kitchen, bathroom; converted the garage into an extension; rewired the house lighting circuit… ) and it worked fine.
Then lo and behold, last night the door goes bang in EXACTLY the same way. That’s TWO doors in less than 48 fitted hours!! And this time, yes, my little girl was right next to the oven as we were baking together (and putting the cake in)!
Rang Extra Care again and got fobbed off once more with a replacement door and when I pushed the matter got put onto a “supervisor” called June. She refused to accept the issue was that glass in two doors had gone in quick succession but instead said it was likely I had banged the first door and damaged it, and that the second door was broken becasue I had fitted it WHEN I WASNT SUPPOSED TO!!! :rolls:
So now I’ve got an engineer coming round next week to “Have a look” but he’s from the manufacurer so hardly an unbiased opinion. And he’ll be able to tell me apparently why both doors have broken.
I’ll show him how I replaced the door and ask him to explain what I could have done wrong that would account for the door shattering (as looking at the basic physics of it I’m dubious if the door actually CAN be fitted incorrectly – its either right or wont shut).
Maybe the first door broke because it was knocked within the first couple of weeks, even though we have a Caravan we go to at weekends and work during the day so only use it once per evening Mon-Thur (maximum used approx 12 times). Maybe the second door went within 48 hours because I fitted the two screws it takes to change the glass incorrectly.
Or maybe MFI are selling cheap rubbish products and hiding behind the “minimum standards” and “how many we sell and how few have faults” to avoid addressing the issue. I’ll see how the engineer visit/third door goes and then approach this with regards to whether the ovens are “fit for purpose” – i.e. is it reasonable to have the glass breaking (and the oven out of use) this often. This is a seperate issue to “safety standards” and they will not be able to answer it with “meets minimum safety standards”.
Hum ho.

I cannot believe so many pf the glass doors have been exploding like this.
We have a Diplomat Double Oven ADP4810 which is 13 months old. Only an hour ago the internal glass door exploded. We have a young son who was in the kitchen at the time and he is very upset. Luckily the oven door was closed so the glass blew into the oven. There was nothing in contact with the glass when this happened and we never use the door to stand anything on when we take things out of the oven.
Do MFI accepy any responsibilty for these failiures? Having seen the mess we had to clean up it will only be a matter of time before someone is seriously hurt in an incident of this nature.
Are spares easily located? Can anyone offer any advice on this please.
Thanks – Chris

Hi Chris,
Door glasses shattering is a fairly common occurrence I’m afraid, there’s an article on it here
I don’t have the info to hand at home but an email to Dave on spares@ukwhitegoods.co.uk will get you a price and availability on them, the most common ones we usually have in stock.

I dont believe you are meant to grill on these cookers with the door closed, certainly when I was doing warranty work the two different makes being used both required the grill door to be open.January 22, 2008 at 1:10 am #171806VampDude

My parents Diplomat 610G’s glass exploded earlier tonight:
I was cooking a pizza on gas mark 5 for 20 minutes, then I removed my pizza from the oven and prepared it ready to eat (slice etc), then I cleaned up as I usually do when I’ve cooked and before I eat (which took about 5 minutes), and when I went to leave the kitchen I heard a noise of what can only be described as “creaking” which I looked and payed no attention and as I went to leave the kitchen I heard a “pop” which to my total surprise the whole of the outside oven door had exploded and covered the kitchen in tiny fragments of glass (the inner glass remained fully intact).

HAS ANYONE EXPERIENCED PROBLEMS WITH THE INNER GLASS DOOR PANEL OF DIPLOMAT OVENS?
I PURCHASED ONE ABOUT 9 MONTHS AGO
YESTERDAY, ON OPENING THE OVEN DOOR TO CHECK ON SOMETHING WHICH WAS COOKING, THE INTERNAL DOOR SHATTERED INTO A MIRIAD OF GLASS PIECES WHICH SHOT OUT AND HIT ME IN THE CHEST.
IF I HAD HAD MY FACE NEAR THE DOOR, I FEEL SURE THAT I COULD HAVE BEEN BLINDED. 🙁
ALL ,MFI HAVE AGREED TO IS TO SEND A NEW DOOR! 👿
ANY COMMENTS
Hi
We moved into a new house in Oct. 2007 and the glass shattered on our model ADP3640 a couple of weeks ago whilst cooking.
When I manage to find out who supplied it I will be seeking a replacement.

Any oven door glass can blow pot luck even if gone few times i have seen them go on diffrent ovens made by diffrent companies under the diplomat/hygena name, it is not a common problem at all, its just scares people when it happens.
Most likely nothing wrong with your oven, but if you are finding its is burning all your food get it checked out incase its over heating by (extracare engineer.)October 16, 2008 at 7:03 pm #171809Quentin
ParticipantRe: MFI DIPLOMAT OVEN
We had an explosion similar to all those described above with the glass door of a Stoves EFa600H. The inner pane shattered for no logical reason after I went to open the door. There was, inevitably, glass all over the kitchen, although not inside the oven. The chicken turned out great, though pity about the oven door. So the problem clearly extends to ovens beyond the Diplomat range.

To simplify a very complex issue:-
Toughened glass is made by heat-treating”ordinary glass….by this, I do NOT mean “window-glass” !
this heat-treatment makes the “skin” of the glass “shrink”…so it’s tightly stretched over the core of the glass……..all edges ,cutouts and holes have the potential to become “stress-raisers”-normally all sharp edges are eliminated by rounding-over and grinding to a smooth finish, prior to the heat-treatment which toughens it. this is an extremely expensive process to do to a high standard. A toughened door to a top standard, would probably tend to LOSE it’s “toughening” over years of heat/cooling cycles.heating/cooling cycles on an oven, will, IMHO, allow stress-raisers to concentrate the stresses-inevitably the skin will puncture and the “pop” take place.
the continued “activity” noted by previous posters, is simply the larger fragments breaking down to smaller ones
Given the price that people pay for these things, the failure-rate doesn’t appear to be excessive……(bear in mind there are probably in excess of 10 MILLION of these CURRENTLY in use in the UK.
I am NOT trying to justify shoddy manufacture, just trying to point out that people wouldn’t pay for a top-quality product (that’s why there are a lot more Diplomat than Aga around)
people want glass doors….i’m sure you could have a much better one made….but would you pay for it?
my cooker is over 35 years old and has a metal door….NO! I don’t want a glass one.
A friend had a Stoves inner skin “pop”….luckily the chicken was wrapped in foil…..so was OK after the glass was removed from the baking-dish.
On the subject of car-glass,-oddly enough, we’ve gone BACK 60 years!
most screens now are laminated-2 thin layers of glass with a sheet of clear plastic bonded between them…..yes, it does break into “spears” but if the impact is large, the screen pops out of the frame. Unlike toughened screens you do not instantly lose all vision when the glass “goes” -
