Burning smell during drying cycle, coming from the inside back left grate. The grate appears discolored.

You have something between inner and outer tub remove top cover smell coming from air vents of outer tub then that is were it is
fun job its has to come all apart

Do u want to resolve the f-13 fault code ON HOTPOINT WD860 Ultima Or Similar.
Fix the fault . It is a tricky job but the heater thermostat switch has tripped as it senses something burning. Probably a little bit of fluff on the heater element inside the heater unit.. There are 2 switches on top of this heater unit. One where the 2 blue wires go on the top left of the 3rd picture and the other which has a tall black wire connector on shown in the middle of the 3rd picture. Remove that connector and undo the holding screw . You can then reset the switch. The switch is a small circular switch hidden beneather the connector on the photos. This thermostat switch has a yellow. red dot ontop of it. If you use a small pin or needle and press into that dot you will hear it tick back into place. you have reset the switch now. You will probably need to clean the inside of the heater element unit to get rid of the fluff particles or it will keep switching off. To take this apart you will need a set of Star screwdrivers. Its a bit tricky but you will be able to undo the star screws and take them all out. I will add some photos to show you the unit apart. You can see the build up of fluff on the photos i have added from my hotpoint WD860 heater unit. This is a tricky job and takes about an hour due to the screw being awkward to take off and put on again but mine hasnt faulted for 2 years since sorting it out. You can buy a new Thermostat switch which is about 10 pounds sterling from Hotpoint or other spares stores.

You probably have a venting problem. If the air cant move fast enough, it will overheat and shut down if working properly.

It appears your clutch assembly has failed in this instance.

For replacement parts - head on over to PartSelect.com or RepairClinic.com and enter in your full model number for a full parts listing.
I recommend both sites because ...


FixYa has no affiliation with either site - I have been using and recommending them for years - trouble free.

PartSelect has a great schematic database for locating the part on your unit and great "testimonials" for each part that often times includes HOW-TO information.
RepairClinic has pictures of each part they sell and also a great how-to and troubleshooting for basic repairs.


If your unit has never been serviced - there should still be an original service manual enclosed in plastic taped to the inside of the shell.
In the service manual are Error codes, maintenance procedures, and troubleshooting steps you can follow.


Anything too complicated or beyond your scope should be handled by a professional.

If you think you want to tackle the repair - and have gotten stuck on a step - reply to your question and I will be glad to help you out.

Hello,
I have this exact same smell issue from the back black panel at rear of dishwasher (free standing so easy to pinpoint. I replaced the old bosch with this Bosch (approx 12 months ago) for the same reason, and am extremely disappointed to have the same issue. It is almost as though the black insulation material is disintegrating? I wonder what it is made from? Smells noxious. It is very hot to touch during a cycle too. Good luck,
Fiona

it sounds like the motor may have burnt out

If the smoke was coming from inside the dishwasher... A common problem is a plastic item , utensil etc has fallen down onto the heating element. During the drying cycle this could possibly melt the plastic and generate some smoke.

Have you checked your outside vent while it was running to see if the dryer was venting 100%. If your clothes are hot and humid I would say clean your vent pipe has a blockage and needs to be cleaned out. Also as far as the burning smell you could take the front off (unplug first) the dryer of by removing 4 screws one above and one below the latch and two at the bottom and there are two clips one at the top left and right push in with a puddy knife and lift the top up a couple inches and lift the front up off the bottom holders. Then you will have access to vacuuming the lint that is floating around the burner.

Sounds to me like the motherboard inside the unit is on it's way to thermal overload. This is a common problem with this particular model. You'll smell electronics burning and one day it'll quit altogether with a burst of smoke. I had this happen to me and I traced the problem back to a faulty triac (transistor-like device) that overheated and caused the circuit board and wiring harness to burn up from excessive current draw. I repaired my motherboard with a new triac ($6) and rewired the harnesses. A cooling fan on the heatsink of the board would solve this problem.
