Question about Bosch Axxis WTA4400 Dryers

Bosch Dryer doesn't dry clothes

I have a WTA4400US Bosch dryer. My husband just replaced the heating element because it wasn't drying the clothes. It seemed like it was getting hot (before and after the replacement) but the clothes still don't dry after an hour on the highest setting. I've cleaned the filter and vacuumed out the duct that leads to the outside vent. The outside vent does not seem to be blocked. Is there another place that could be filled with lint that I'm supposed to clean out?

With the dryer not connect to the external venting turn the dryer on and see if there is air coming out ot the vent from the dryer. Is this flow of air strong or weak?
If weak then there could be a problem inside the dryer some where. Perhaps the fan is not operating properly. Just my thoughts.

You say you have check the beginning and end of the duck vent pipe. How about seeing if it venting duct is clear from one end to the other.

Good luck

Hi-Limit Thermostat


Hi Frank Liles..
Here are a few causes and things to check

Clogged Vent
If your dryer seems to run forever, it could be because of a clogged vent or internal ductwork. Your dryer may have an automatic cycle that turns off the dryer when the clothes are dry. It does this with a special thermostat or moisture-sensing system.
Normally, this is what happens during an automatic cycle:
The thermostat tells the dryer to heat until the interior of the dryer reaches a pre-set temperature--say 135 degrees.
When the dryer reaches the pre-set temperature, the thermostat tells the timer to begin advancing. (If there's a moisture sensor, the timer advances only if the moisture content of the clothing is low enough.)
The timer advances until the interior cools, then the thermostat tells the timer to stop advancing, and tells the dryer to start heating again.
This cycle continues until the clothes are dry.
But...if the vent is clogged, the dryer may never reach the proper operating temperature, so it doesn't send the signal to the timer and the dryer continues to run indefinitely, even if the clothes are completely dry. To fix the problem, clean the vent and/or internal ductwork.
Heating Element
Your dryer's heating element may be partially burned out. If it is, your dryer still heats, but at such a low temperature that it takes three or four times as long to dry the clothes. If the element is partially burned out, replace the heating element. You can check for an ohm reading but will need to refer to the service manual for proper reading. This sometimes on the tech sheet located somewhere on the dryer. Usually between 9-13 ohms.
Cycling thermostat
Although this isn't a common problem, one of the thermostats that controls the temperature in your dryer may break and cause the dryer to heat poorly. If so, you need to replace it. The thermostat is usually a small, round, black device mounted to an oblong steel plate. The plate is mounted to the internal ductwork .
This thermostat usually has four wires going to it. Check the 2 terminals that are opposite each other and are the closer together of the 2. These 2 terminals should have continuity. If not replace the thermostat.

Clothes not drying


Clothes not drying? Thats it? Does the dryer turn on at all? Does it tumble the clothes but doesn't get warm? If it turns on and tumbles but takes a long time to dry, then your heating element is not working. There is a thermal fuse right before the heating element that will open up if the vent becomes clogged and its gets too hot. The thermal fuse is not resettable and will have to be replaced. If the thermal fuse is o.k. then your heating element could be burned out. These two items almost require an electrical meter to read continuity to check them. Make sure the dryer is unplugged before checking these items.

I have a Maytag Legacy Electric Dryer Model MED5570tq0. It turns, gets heat, but does not dry the clothes. It would take 2-3 cycles to dry clothes. Any suggestions?

Bosch axxis wtl 5410 dryer takes too long to dry.


You should have a cycling thermostat. this is most likely bad or your dryer vent may be clogged. Something is cutting the heat off before it gets hot enough. Both these cause this problem.

Dryer won't heat up to dry the clothes the heating element works


Check the following to address this issue--


Note: Normal drying time for a dryer is about 45 minutes (some may take up to an hour).

1. Venting
Make sure the dryer vent hose, as well as the rest of the vent duct, is not clogged.

Unless regular maintenance is performed, chances are there is a lot of lint accumulated inside the dryer. This might affect the drying time and could be a fire hazard. Make sure to have your dryer cleaned regularly. Because this might involve taking most of the dryer apart, it is recommended to have a qualified appliance repairman perform this task.

2. Thermostat
There are a couple of cycling thermostats inside the dryer. If one of them breaks down, it might affect the dryer's performance. Replace the defective thermostat.

3. Heating element
A heating element might only be partially burned out, in which case it would still work but will take longer time to dry the clothes. Replace the element if found defective.

Dryer no longer has heat to dry clothes


The element gets brittle and breaks. The element is in the rear of the dryer under the dustcover.
