    Thank you. Either the heater element was partially 'burned out' or at least clogged. Now waiting for the new heater element.

    I have now replaced the heater element with a brand new spare. Initially, it briefly was glowing, but now it stays cold. Is it therefore the thermostat? It that the piece sliding on the drum surface? Any way to short or test the thermostat?

    Seems the high limit thermostat had opened when I tested the heating element after installation. I reset the high limit, and, now the dryer appears to work OK, at least initially. Thank you.

    After installing the new heating unit (and resetting the open high limit thermostat attached to it), the dryer initially worked. However, the first 'real' drying load appears to have again released the high limit thermostat, as no hot air is produced. I guess I now need to proceed to check if anything obstructs the airflow, leading to overheating. The condenser has been regularly rinsed, thou.

    Could the temperature regulator, located under the door, be faulty, leading to overheating?

    I now have a new temperature regulator for the dryer. How do remove the old regulator and its seal from the door frame?

If the dryer blew a fuse, it sounds like the heating element has gone, and drew enough current to take out the fuse.

If this is not the case, the thermostat may have burned out, which it can do if the condensor is not regularly cleaned.

Good luck!

    The thermostat should be located on or near the drum, and should have two wires connecting to it. In order to test the thermostat, you will need an ohmmeter, which measures resistance. You must temporarily remove the two wires connected to the thermostat and connect the two ohmmeter leads to the thermostat connecters. If the thermostat is good, you should be able to see the resistance change if you apply heat to the thermostat, such as with a hair dryer. You may have to change ranges on the ohmeter to see a reading other than "1." which indicates that the measured resistance is higher than the selected range. Most digital multimeters have resistance ranges of 200 ohms, 2000, 20K, 200K, and 2000K. If you do not see readings other than "1." on any of the ranges, this indicates the thermostat has an open circuit (no internal connection) and should be replaced.
    Good luck!

    Checking for obstructions would be wise, and shoud be done regularly.
    You said that no heat is produced, however, so it doesn't appear that overheating is an issue. The temperature regulator may prevent the dryer from heating, however. It's difficult to diagnose problems without being able to see the appliance and its symptoms.
    At this point, you may want to consider getting in touch with Bosch Customer Service to find out their recommendations, if you haven't already.

Hi. My Bosch WTL 5500 wont start. It has power and filters are clean. When you push start the dry light comes on and nothing happens. Any ideas?

there is a thermal reset button at the back of the unit on the heating element. to get to it you have to remove the back panel that covers the heating element. (its the panel that sticks out). Once that panel is removed you will see the red thermal reset button. press it so it clicks, then start unit. Let me know what happens.

the thermostats at the element have to be replaced, they burn out prematurely if the condensor unit is not cleaned on a regular basis.

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.

Re-set button location?

you need to remove the back panel the smaller one that covers heater matrix you will find a thermostat with a red reset button on it when you push it it will click and reset however you should find out why this happened before you use it again as it only does this if it overheats.

hope this helps
