Question about Bosch Axxis WTA 3510 Electric Dryer
Hi My two years old dryer suddenly stopped producing warm air. It's working with cold air and the clothes takes forever to dry. I'm gonna call a technician but I was hoping you might help me find what's the fault could be. thanks for your Help, Michelle
Hi there, I have had the exact same problem with my dryer also. Mine is the same model as yours. I did some digging with a borrowed multimeter and I found the problem to be the thermostat that is inside the drum itself. If you can, open the door and position yourself so that you can put your head inside the drum of the dryer with your face towards the ceiling (not easy, I know), you will see a silver coloured button like device fitted to the inside of the front of the drum area above the door opening. Note, this part is not attached to the drum itself, and does not move, but instead it is attached to the front "wall" of the drum. There are two phililps head screws holding this in place. Undo these screws and the retaining piece of circular plastic will come off. You can then get your hands on the thermostat. ( I have enclosed a picture of the item in question). Remove both spade connectors and that is the thermostat removed. (Remember to pull the two pink coloured wires through the hole and maybe tape them to the inside of the drum so that you can get to them later.) You can test the thermostat by checking for continuity between the two spades. Test it first when it is cold, and then dip the "button-like" part of it in hot water until you hear a click, test it again and the result should be different. You should have continuity when it is cold, but not when it is hot. The part ( Part No. 125 84 06-10/5) is reasonably cheap to replace, I got one for 25 Euros, and the dryer has not missed a beat since. Please note that when I rang various suppliers looking for the part, they all told me that it normally does not fail. I was not put off by their attempts to have a service engineer come out to charge me 50 Euro to tell me what I already knew, so be prepared to stand your ground if the above test indicates that this thermostat is to blame. When you get your new part, dont worry about which pink wire went onto which terminal, because it does not matter. It is just a switch really. I hope this is of some use, and perhaps you have already solved your problem, but maybe someone else will get some benefit from all my typing. It took me about an hour! Cheers!

My Use and Care Manual suggests for the problem of "Drying level not reached or drying time too long" to "Clean the Moisture sensors in the drum as described in section titled CARE and CLEANING" which then states: "Occasianally the moisture sensors will need cleaning, due to a build-up of a fine layer of lime scale on the inside of the drum. This build-up of lime scale can be easily removed by wiping the sensors, the metal inserts in the paddles, and the inside of the drum with a soft cloth soaked in vinegar (use white vinegar). See Figure 10." You may want to try the vinegar trick before you start tearing into your unit. I hope it works and good luck, Del

There are also small silver coin shaped devices called thermal cutouts that I have found bad many times and are located on the vent , the rear panel ??It depense on the manufacture

If you still have your instruction manual check to see if there's a cut out or trip switch. If there is, a simple push of the reset button could fix your problem. Check your outlet filter. If it.s clogged with dust and fluff, give it a good clean and replace. Blocked filters can cause the safety device to deactivate the heating element. If all this fails the heating element is easy to remove. Take it to your hardware store and ask them to check it. Obviously if you do have a multimeter and know how to use it you can check it yourself. If not and the hardware shop says it's burnt out then get them to order a new one. Prior to refitting the element give the dryer a good clean out. You'd be amazed at the amount of lint and dust there'll be just waiting to clog the works up again. As usual, always remove the power cable from the wall when working on household items. BMW

Michelle, I'm not famillier with this specific drayer, but I can give you some general direction to solve your problem. Its look like heating element (a simply long coil of special wire) problem. Open rear panel of the dryer and check for heater's resistance (by ohm-meater) Be aware you should do it while drayer power cable is is disconnected !!! In case there is no resistance, you should replace the element. In case you have a resistance meserment: -On many dryers, there's a thermal fuse mounted to the exhaust duct inside the back cover panel (in a white plastic house). If the fuse has blown, it should be replaced. - look for no burned wires or bad connections. Good luck!

have you checked the vent line it could be stopped up if the line is bent same affect as the lint filter being full

check to make sure lint trap is clean also make sure exhaust is not clogged. if both are clear than you probably need to replace your heating elements. if this the case than you need to call an appliance repair tech. trying to do it yourself could result in electricution. also make sure your drum is turning.
