Understanding the Heating System:

Before delving into troubleshooting, it’s essential to understand how the heating system in your Bosch dryer works. The heating element in your dryer is responsible for generating hot air to dry your clothes. It is powered by electricity and is controlled by various components, including thermostats, thermal fuses, and the main control board.

Troubleshooting Steps:

1. Check the Power Supply:
– Start by ensuring that your dryer is properly plugged into a functioning power outlet.
– Check the circuit breaker or fuse box to see if there’s a tripped breaker or blown fuse.
– If the power supply is intact, move on to the next step.

2. Examine the Heating Element:
– Disconnect the dryer from the power source before proceeding.
– Locate the heating element at the back of the dryer.
– Inspect the heating element for any visible signs of damage, such as breaks or burnt areas.
– If you notice any damage, the heating element may need to be replaced.

3. Test the Thermostats:
– Thermostats are safety devices that regulate the temperature in your dryer.
– Using a multimeter, test the thermostats for continuity.
– If a thermostat fails the continuity test, it may need to be replaced.

4. Check the Thermal Fuse:
– The thermal fuse is a safety device that cuts off power to the heating element if the dryer overheats.
– Locate the thermal fuse, usually found on the blower housing or the exhaust duct.
– Test the thermal fuse for continuity using a multimeter.
– If the thermal fuse is faulty, it will need to be replaced.

5. Inspect the Main Control Board:
– The main control board controls various functions of your dryer, including the heating element.
– Look for any visible signs of damage, such as burnt components or loose connections.
– If you suspect a problem with the control board, it may need to be replaced.

6. Clean the Lint Filter and Vent:
– A clogged lint filter or vent can obstruct the airflow, leading to poor drying performance.
– Remove the lint filter and clean it thoroughly.
– Check the vent for any blockages and remove them.
– Regularly cleaning the lint filter and vent can prevent future heating issues.

7. Seek Professional Assistance:
– If you’ve followed the above steps and your Bosch dryer WTG86400UC/01 still isn’t heating, it’s time to call a professional technician.
– An experienced technician will have the expertise to diagnose and repair complex issues that may require specialized tools or replacement parts.


Dealing with a Bosch dryer WTG86400UC/01 not heating can be frustrating, but with the right troubleshooting steps, you can identify and resolve the problem. Start by checking the power supply, inspecting the heating element, testing the thermostats and thermal fuse, examining the main control board, and cleaning the lint filter and vent.
