Dishwasher Caught Fire

[gadgetgary]

This is an interesting threat posted on the 'Appliances Forum':

Didn't find anything on a search...
Our POS Jenn Air (made by maytag I believe) dishwasher was 12 years old. Pretty noisy so we always set it to wash during the night when we were sleeping.... so, two weeks ago I am awakened by the SO with "Do you smell that?".

Downstairs we go- yes, it is smokey...and it is coming from the dishwasher. Open it up- Yep definitely. I declare that it must be a plastic tupperware on the heating element.

We open the house up and air out the smoke. Run the whole house fan for a few minutes.

But still a strong smell and some smoke coming out of the DW.... I reach in, and feel the element...cool... uh, oh.

Tools.

Remove the lower panel: Insulation on the underside is ON FIRE! Red smoldering embers, smoke... Pull it out and toss in the sink... put it out.

Ultimately I determine the cause: one of the wires to the heating elements broke at the crimp connector (stress concentrator).... over the years the vibration led to the wire failure. Once the wire broke the current arced and caught the insulation on fire.

Sobering... another way for appliances to kill.

So, we have a new Bosch SHE66C05.... sweet.

OMG scary. Never thought of that possibility.

And that is why it is

not a good idea to run appliances at night or when the house is empty!

Well, I guess you got a heated dry with that load whether you selected it or not.

(Tom, you got the Tasteless Tidbit of the Day award for that comment

Seriously though, I never understood how someone can press a button on a washer, dryer, or dishwasher, and then leave the house or go to sleep. The rule has always got to be that when the machine is running, you can see it or hear it, and you're in the same airspace with it so you can smell smoke if there's a fire.

Same case for stoves, ovens, microwaves, breadmakers, toasters, coffeemakers, and all the other little electric wonders we have around the house, and the fireplace if you have one.

Low wattage isn't an excuse either; after all a switch or small motor can also short out and cause a fire. For that matter unplugging stuff when not in use will prevent trouble if there's a short in the plug. And always unplug by grasping the plastic plug itself, not by tugging on the wire, which will cause the wire to fray internally and is a major fire hazard.

Last but not least: You've got your smoke detectors and so on, now spend another few bucks for a couple of large boxes of baking soda. When thrown on a kitchen fire, it will soak up grease and will also release CO2 to help extinguish the fire.

Hey hey hey

That was NOT tasteless. It was genius!

Tasteless, as well as classless and inappropriate, would be MY domain.....and don't you forget it.

*LOL*

I was wondering if anyone sold a power cutoff system for the home similar to the systems that are used in commercial buildings. In those systems, the electrical circuit in the affected part of the building is shut off to minimize the danger of live wiring, or if the fire was caused by an electrical source.

I just recently purchased a nifty smoke detector system that will transmit a radio signal that causes other smoke detectors in the home to sound, even if they are not picking up smoke.

When our kitchen was remodeled in the very early 70's, the dishwasher was put on its own switch above the counter for emergency shut offs. We never used it, and every few years someone would ask "What does this switch go to?" I was the only one who ever remembered.

If someone would like a 4 cycle Waste King dishwasher in central NY, please let me know...

Response: Not sure exaclty what is being asked, but I did find ARC interruptors in Home Depot, which I understand is now required by code for bedroom circuits.

Like a GFI /GFCI [a/k/a residual current detector] there is a commection to neutral required in the circuit-breaker panel (consumer unit=> UK).

Oh no that is so sad. A similar thing happened to me once but i could restore the machine. It was the motor in my Hoover Keymatic that almost caught on fire. Lyckily i had just come home from shopping so i could turn off the machine before it could spread. The wires in the motor looked really bad i can tell. Now it has a working motor in it again and the machine works tip-tip as far as i can see.

Fire is of course a concern. I know one family that not only doesn't leave anything on when they sleep or leave the home, but they also unplug any appliance once they are through with it.

I'm quite the opposite. Everything - except those things with parasitic energy drains above 1 watt - stays plugged in when not in use. I also don't have a problem setting the dishwasher to run before I leave for work or go to bed, although usually I set it to run in the evening while I'm still awake. My feeling is that a quality appliance with a good safety record is safe to leave plugged in and to run unattended occasionally. I don't like to leave stoves or ovens run unattended, though.

 

[mixfinder]

Agreed

I am with you Sudsy.
I have to trust a few things to do what they are supposed to do.
I may unplug the dishwasher after only running when I am home only to die from something else.
Life is too short to take on every worry.

.... I am with you boys.........then the wear-and-tear on the outlet will cause a fire from the constant Plugging and Unplugging. Especially if you pull cords rather than properly pull plugs.

And I'm not telling what I pull; and if it's burning from the "P & U" get thee to a doctor.

I am glad that you were ok!!!

Ther is a house around the corner from my mother that the people were not so lucky. In Vancouver,Wa( where I grew up) A dishwasher burned the house to the ground. No one was hurt, They have since rebuilt the house and all is well. That is a very good idea having a seperate breaker for the dishwasher so close to it.

 

[awooff]

Same kind of fire happened to me with a haier 18 in dW!

 

[sudsmaster]

I would say that exposed heating elements present a greater fire risk than the in-line water heaters of euro models like Bosch and Miele.

Interestingly, just tonight I was washing a new set of glass storage bowls in the '57 KA KD-2P portable dishwasher. The lids are red vinyl or similar sort of soft rubber. During the spraying they kind of flew around the bottom of the washer. One landed between the cutlery tray (empty) and the heated air inlet. During the heated air dry, the air flow was hot enough to melt one of the lids pretty thoroughly, and damage another one. There was no danger of fire, but... probably the last time I put in anything meltable that can become airborne in the KD-2P's powerful spray action, unless I can check before the heated air dry starts.

On the plus side, I definitely know the heated air dry function is working!

Electricals

Im kinda in the middle myself, I will leave appliances on and pop out, but only if I know I will not be gone long, and again it depends on what kind of appliance. Anything that heats Im wary of, so I would never leave the tumble dryer on or a dishwasher, because of its drying cycle. However when I had a washer dryer, I did used to leave that running and go out, mostly cos the damn thing took so long to dry!!!

I DEFF would NOT leave an oven on auto, or microwave thats just asking for trouble, but I do use my teasmade every day , and thats next to my bed!

As for better quality appliances not causing fires?? I dont agree, a loose wire is a loose wire no matter how expensive the appliance is.

I think most of all tho - why would you leave appliances on when you out? - You dont save much money by doing stuff at night, and I actually like to know when the dishwasher has finished or the dryer.

I dont think we can be silly tho, all this unplugging everything if its not in use is pointless, tv's radios' clocks, microwaves, these need to be plugged in all the time, Im not gonna scrabble behind my big tv just to plug it in. But these are all realitly low power users, i think the trouble comes with white goods.

Oh British Telecom over here do a great wireless home system.

Its a series of smoke alarms, burgular alarms, carbon monxide detoectors and cameras, that all link up wirelessly to one another and to your phone line.

If anything happens it calls you and tells you, and if it cannot contact you then it calls neighbours or friends.

ALso you can check everythings ok on the web cam.

A little OTT but its nice to be protected.

Oh god look at me going on!! this was only meant to be a short reply - sorry guys!

 

[toggleswitch]

..and if the phone line burns?

I actually slow-cook in my electric oven, leaving it unattended. I set the oven to turn on, do its business and turn off. (But then the oven is less than 3 yrs of age). I feel safer doing that with electric than gas, and 250*F (120*C +/-) appears to be tame. (Paper auto-combusts at 451*F).

At that temp., the water/moisture the food gives off (Cooking makes food tastier by reducing the food's water content therby concentrating the flavor), exceeds the evaporation losses. There will be more water in the pan than when you started. Not to mention fat and grease and drippings. There is very little chance of burning a pan, IMHO.

One of the reaons raw food is healthier than cooked is that it has a higher water content. The moisture has not been driven out by heat. Ditto frying~ removes the most moisture/water; results in unhealthiest foods.

So we are back to=> Be careful don't become consumed by fear. The universe gives you what you think about most, good or bad.

When you time is up. It's up. NEXT IN LINE PLEASE.

I tend to gnosh until just before retiring, so it's handy to wait until then to fill up the dishwasher and start it at that time. In rhe morning, clean dry dishes, and nothing dirty cluttering up the sink.
