SOURCE: Washer was pouring out smoke and smelled liked burnt rubber

You most likelyhave burned a drive belt. Could be a couple things. If the machine was loaded to the max and a bit more, it is possible that a small article of clothes may have been flung into the outer tub and into the pump... this can freeze it up and the motor will keep trying to turn the belt against a frozen pulley.
You'll need to open the machine and check the pump for blockage and change the belt... let us know if we can help with procedures..

SOURCE: GE washer stopped spinning and smell of burning out lingered

I am going through this right now and best I can tell..needs a new belt. Pop the front off of your washer (UNPLUG IT FIRST:)) and see if there are black shavings on the bottom. The appliance place where we usaully order our parts from do not carry this belt in stock so it will have to be ordered. Price from them was $19.00+ tax

Hi.
It is very likely you need to replace the motor brushes. These are the electrical conections in the motor that wear after a time. They are fairly cheap, uses-replaceable, and available from online appliance specialists.
Turn off water and unplug before removing top/ back pannel to access motor. ***** CHECK MOTOR TYPE BEFORE ORDERING PARTS ******

My front load washing machine is working but the water don't seem to enter.


First of all check filters in hoses & water valves, if ok then water inlet valve may be burnt out. Unplug power cord, remove top panel panel, check where 2 wires go to each water valve & check that area on valves for burning. If burnt or smells of burning, replace valve. IN SOME INSTANCES A COMPONENT BURN OUT CAN CAUSE DAMAGE TO CONTROL BOARD.

My LG washer stopped mid-load at spin cycle, how can I fix this?


It sounds like a serious fault if there is no power the fuse has gone or some item has burnt out . You will have to arrange for a service engineer to look at it more closely.

First place to check after you disconnect from mains is remove top cover and inspect and sniff control board.it should not emit burnt smells or show burn marks...inspect wiring loom off panel and see if any damage has occurred.finally you need to inspect the heating element itself which rarely fails or burns out. By looking from bottom area of drum...again you are looking to find telltale signs.if it is the controller ....these are often on eBay sold as replacement boards .i must warn you that there is no guarantee that this will mend the problem as a short seems to be more likely...possibly due to water ingress or damp environment condensation on the pcb due to some sort of internal leak etc.and this needs to addressed to prevent repeat of same problem.

Maytag quiet series 100 stopped midcycle, smells a little bit of smoke


sounds like a burned belt, once the belt is burned from being loose, the burnt spot gets hard and the pulley will not catch to make the machine run , replace the belt.

LP3065 top arrea darker - backlight defect?


what you can do is to remove the back cover to access the inverter board. probably the cause of the smell is burned inverter board for the screen back light ( ccfl ) at the upper portion of the display.you can find the inverter board near the power supply board. usually you will replaced the inverter board since most of the part get fried as will as the pcb pattern circuit board get burnt.hope this can help good luck.

Hello,

Welcome to FixYa.


Based on your post it may just be a loose/burnt connection in the dishwasher junction box.

**Now I would start by first shutting off the breaker...safety first**

Then removing the kick plate ( access panel at the bottom )...

...and checking the wiring at the junction box for the dishwasher 120vac supply line.

Remove the murret's and visually inspect the wire for "resistance burn" and strip the wires back and install new fastener's if necessary to repair.

i.e.

60f6a31.jpg

This is actually quite common to find a wire connector come loose due to improper fastening and once the unit is in use for a while the connections heat & cool, become loose from normal operating vibrations and burn up from all the added heat caused by "resistance".

Typically this will manifest in just the manner you've described. It is possible the control may be the culprit, but I'd check the jinction first.


Let me know what you find and I'll try to assist you further if necessary. I'd still suggest looking into the possible recall for your machine though.

Regards,

Macmarkus :)

The washer was in spinning cycle, when I smelled plastic burning, then it stop all together. I was able to turn it off, but now it doesn't do anything. What could this be?


It will be good to start with looking into the washer with the power switched off smelling for the source that burnt. this will be easy to find and the possible area could be the power section in the main board- the control board.
Once you have isolated the burnt component we can decide if the part alone can be changed or the full board needs a change.
The motor and the drain pump also must be checked for any burnt outs.

Burnt spot on board


Depending on what caused the burn spot. It is possible to solder a bridge or jump wire from the point on the board that is not damaged and follow the trace or film connection to the next point that is to connect the two points. Other wise find a solder point on one side of the burn and if you can follow the path to the next solder point, use a jumper wire and solder each connection bridging over the burn. Wire has to be insulated. Some burn spots are caused by poor factory dipping of the board, and the solder loses connection over time from heat etc.
