Question about Dishwashers

Bosch Dishwasher Classix

Dishwasher was running fine.  I smelled a burning smell.  Stopped washer.  Visually checked things out-didn't see any smoke-turned it back on.  Smelled smell again-smelled like wood burning!  Turned off machine, unplugged and tried to pull it out.  See no signs of fire and now machine will not turn on at all-no lights, no noise (yes it is plugged back in)

I've had the same problem TWICE. It seems the natural vibration of the machine loosens wire nuts and leads to the problem. Soldering the connection and then placing a yellow wire nut over the soldered connection works fine to stop the problem. This machine has a electric water heater to sterilize the dishes and draws a lot of power, near the limit of the connection, more than a standard dishwasher. I called Bosch twice about this problem, only the second time when I stated that my lawyer might call them back did they admit that there is an issue with the vibration of the machine leading to the wire nut becoming loose and suggested I solder the connection. Great dishwasher, lousy customer service. They have know about this problem for years.

Had similar problem on my Siemens which is the same as Bosh. I started to take it apart to see what had gone wrong. Eventually I had to disconnect the cable going into the washer - its in a small box at the front at the bottom. The wire nut connectors had melted and shorted out. Unfortunately now it won't fill with water. The smell was not like wood so maybe a different problem.

It stopped running and has a smoke smell. It will not drain or do anything.


Hello,

Welcome to FixYa.




Based on your post "It stopped running and has a smoke smell. It will not drain or do anything." it may just be a loose/burnt connection in the dishwasher junction box or a severed wire in the door panel.

** 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.

If it looks OK there I'd remove the outer door panel ( careful the edges are sharp ) via the six #20 torx head screws...

macmarkus_168.jpg


...check for a severed wire at the pivot point in the door, typically covered in a plastic casing as shown here..
.

macmarkus_169.jpg

The small plastic blocks which may be present in the bottom corners of the door panel, i.e.

macmarkus_170.jpg
...they can be a pain to re-install, but they do only go in one way, however it is ok to leave them out...their only purpose is to strengthen the structure.

Let me know what you find and I'll try to assist you further if necessary. Thank you for choosing FixYa today for your inquiry.

Macmarkus :)

Hello,

Welcome to FixYa.

**Before I begin I will inform you B/S/H/ ( Bosch Thermador, Gaggenau ) issued a recall on certain models between 1999 - 2006 depending on the serial number.** Here's the link so you can see for yourself.

http://microsites.boschappliances.com/safetyrecall/dishwasher/

Aside from that and based on your post "my bosch shu43co5 made a burning smell and stop working in middle of a wash the breaker seems to be fine" 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**

Smell of electrical burning


The first thing I would do is to make sure there is not a piece of plastic laying on the heating coil on the bottom of the washer.

Bosch Dishwasher SHX46A05UC/23 - No Water


Sounds like your recirculating pump is clogged If it is water can't get up enough pressure to turn the sprayers.
You'll need to start pulling parts out of the bottom inside to get to that pump. I don't work on a lot of Bosch, but that sure sounds like it to me. I see this a lot. Hope this helps...

Whirlpool 24" built-in GU1200XTLBO dishwasher electrical smell


This may be the smell of Varnish used in motor winding. When we turn on the machine it gets heated a little bit resulting in a burning electrical smell.

SHU43 Bosch Built-in dishwasher


Try running citric acid (3 tablespoons) through.
You can get it from a drug store.
Or, run 1/2 cup vinegar through.
Do this in both the dish washer and the disposal.
After doing this try running some water into the disposal and then see if the next time you run the dishwasher if it still smells.
You could be having a problem with water not staying in the drain trap under your sink that is why if you run water and fill the trap, then you will find out if it was the dry trap that caused the smell from sewer gases backing up into the house trough the garbage disposal.

Smelled like burning plastic


Ron, is this a dishwasher or clothes washer? If a dishwasher, check the wire nuts in the junction box. If there isn't a melted wire nut from a loose connection. Then you have to pull the outer door panel, then you can pull the control panel assy. This will require a t20 torx bit.

Bosch Model SHU4006C Dishwasher


I just bought a Bosch made for Sears and I'm trying to return it. I'm going to get a Kitchaid instead. We got ours two months ago and Sears is being difficult in letting us return it. I had a technician come to the house and he said it smells--slightly oily or rubbery. I went to a store and all of the Bosch dishwashers smell. Anyone reading this, don't get the Bosch.
