MFI DIPLOMAT OVEN

[jaycee3]

HI

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

Re: MFI DIPLOMAT OVEN

This peice of glass could of had a minute crack in the corner, since manufacture, and at the given moment when you opened the door the cold are would have met the hot glass and caused it to shatter.

Hope this helps

Hi jacee3

the Glass could have any point in its life been knocked or had a sudden shock(cold tin/casserol dish) placed onto the glass when hot.

due to the glass heating upand cooling down and it is still in fact a liquid the chemical formation can just break down.

hope this helps

Re: MFI DIPLOMAT OVEN

To add comment to R600 & WhiteVanMan

Oven door glass is ofdten made from “Soda Glass”
It is designed to shatter into small pieces if it’s put under undesigned stress load or develops a fault, especially if the glass is still hot/warm

It is extremley unlikely that you have an additional fault on your appliance
Even failed thermostats wont cause the glass to shatter

and although as a manufacturers engineer i have replaced many a shattered door assy in my time, its pretty rare

Just thought i’d add that to re-assure you a bit

Re: MFI DIPLOMAT OVEN

Hi

Drop down glass doors on ovens are not really designed to be used as a shelf , so resting cold dishes on them when the oven is up to temperature can cause damage, which often them to shatter some time later .

Re: MFI DIPLOMAT OVEN

The internal glass panel door of our diplomat oven shattered last night. While it was more like exploded with hot glass shards pouring out of the bottom of the oven and landing 4-5 feet away. My a wife was about foot away from the spillage, I hate to think what would have happen if one of my small children would have been in range.

I have found 2 other references of people with the same thing happening on the web through google. How big problem is this ? That’s 4 people reported it on the web, if thats 1 per cent of all incidents. Could this be a dangerous design fault in these ovens ?

Our oven has always been well maintained and the door has never been used as a shelf.

Re: MFI DIPLOMAT OVEN

I have this oven and I’d be careful if I was you. I’ve had the oven door glass blow twice already and recieved a call from the people renting my flat that it’s again blown tonight. I’ve heard it is a design fault whereby the metal shelf in the oven touches the glass and thats what causes it to blow, whether due to the door closing on it and damaging the glass or the heat being transfrered into the glass I don’t know. I’ll be pushing MFI for a replacement this time, for a different manufacturer. Take care

Re: MFI DIPLOMAT OVEN

It happens I’m afraid. 😕

A flaw in the glass, a thump, carelessly slamming the door shut or resting cassaroles and the likes on it will all strain the glass.

As Whoppo said though it is fairly rare and generally doesn’t happen repeatedly at all, in fact I’m struggling to recall the last instance it happened to one of my customers more than once. Id be asking the tennant what they’re doing although if they are doing something wrong I doubt you’d get an honest answer.

Whoppo is also totally correct in that this is a type of safety glass, it shatters in the same manner as a car’s window adn is intended to be as harmless as is possible.

My repair business does more than a few calls on MFI, Hygena and Diplomat ovens and cookers in any year and this isn’t a problem on them. We replace a few a year, but no more than we do for any other manufacturer.

I am totally unaware of the metal shelf touching the glass, that’s a new one on me and I read every service bulletin that comes in.

If you search for the problem under other brand names I expect you’ll find just as many instances on other brands too.

Re: MFI DIPLOMAT OVEN

Appreiate your response K, but 3 shattered glass panels from one oven door is ridiculous. My tenant has only been in a week and it’s happened on two other occasions, either I and the other people on this forum are extremely unlucky or MFI are selling crap ovens, I know which I think it is. My complaint is being investigated by trading standards so we’ll see what they have to say.

Re: MFI DIPLOMAT OVEN

Don’t get me wrong Ritchie, some of the budget appliances in any range can be, not the best, will we say and, to a large extent, it’s the old story of you get what you pay for. This applies to both build quality and performance, just like most products.

I would say you’ve been extremely unlucky as I’ve never heard of another instance where a door glass has repeatedly failed on here or in thousands of service calls. So from that you’d have to agree that it is unusual.

With that in mind, if it were me calling to inspect the appliance, I’d be looking for an external cause.

Can you tell me what model it is and how old it is?

As for the other posts, I’ve not seen one where this has happened more than once. The main concern is one of safety. It can also give people quite a start when these things pop asn they do tend to be pretty spectacular when they shatter but the risk is minimal, or as minimal as it can be made.

In the end, regardless of how over the top you are on safety and quality, any machine (and I mean machine, not just an appliance) has the capacity to fail in some way or another and they all will eventually break down. Oven door glasses popping are a thing that’s always happened and there’s little that can be done about it as, like any other component, they can fail. In my experience they do not fail that often, certainly not often enough to have given me any cause for concern.

Re: MFI DIPLOMAT OVEN

Hi
Just to add to what kwatt said about things that can cause the glass to explode, a popular one is draping a damp teatowel over handle and allowing it to touch the glass whilst oven is still hot can result in the glass shattering.

Re: MFI DIPLOMAT OVEN

I had exactly the same thing happen last night, the oven had been on and within 5 minutes of it being switched off, door closed the glass exploded into the oven and through the bottom of the door. I seem to be reading of this problem on a number of websites with this particular oven. I can’t believe MFI have sold so many for this only to be a small percentage of failures it looks like a design fault.

Re: MFI DIPLOMAT OVEN

There’s not one model number in this thread, MFI use several manufaturers to produce their appliances so you could have machines from Brandt, Stoves or a host of others all with the same “fault”. When you square that with the number of instances it is probably statistically very, very low.

Are you sure about that? or telling a Whoppo I wonder? 😉

I’ve been reading the thread with interest as to the reasons and theories of why oven door glasses suddenly break? And suspect the reasons (like the answers here) are various?

But I think from the outset that all ovens no-matter what make, are likely to experience the same effect albeit extremely rarely.

Likely reasons ( my theories into the phenomina :rolls: ) are:

1) Poor quality construction of door and door framework (design fault?)
2) Toughened oven glass scratches easily (oh yes!) and is weakened as a result?
3) Previous impact from cooking pots can cause microscopic fractures that only manifest through later use? *
4) Chemical reaction from caustic oven cleaning materials, break surface tension in the long term?
5) Sugar spillages – (fruit pie juices etc?) – sugar eats into the surface!

* Running a finger along the rim of a wine glass creates vibration (very audible and entertaining that effect can be) and no apparent damage to the glass? Until you place it in warm water that is? 😯

Re: MFI DIPLOMAT OVEN

I had the same response from MFI as kwatt gave. The glass is made to European/UK standards and if it breaks the glass shards are harmless just like a car windscreen.

I’ve got news for them the car windscreen glass shards are not at 210C. The glass shards were so hot they were moving around as they cooled.

And this is literally an explosion with the glass being pushed out of the bottom of the oven and travelling 4 feet away almost instantaneously. Cheap or not this should not be expected. By the way this is Diplomat ADP3640 worth 369 pounds, is that cheap !?!?!?

Also the oven door is spring loaded, the glass is unprotected from anything in the oven and worst all the hot glass shards are released straight into immediate vicinity.

My case has also been forwarded by Consumer Direct to Trading Standards also. Meanwhile my children totally banned from the kitchen while the dangerous thing is on.
