Before trying any troubleshooting steps below, ensure the dryer didn’t trip the circuit breaker. Most dryers will have two connections: one for tumbling and the other for heating.

Sometimes, having too many power-hungry devices running simultaneously can cause an overload. In such situations, the circuit breaker trips to prevent damage.

Here’s how to check whether your circuit breaker is tripped:

1. Locate the circuit breaker in your house. If you’re unsure about its location, ask an electrician to help you. 
2. Check the position of the dryer’s circuit breaker and move it to the off position. 
3. Push the circuit breaker to the on position. 
4. Try another dry run and check the dryer’s interior after 10-15 minutes. 

If these steps don’t fix the problem, proceed to the next hack below.

Once you know the dryer doesn’t heat in any setting and the circuit breaker is okay, you can troubleshoot the device for other issues. But before you do, ensure you unplug the power cord from the socket. You want to minimize the chances of an accidental electric shock.

Typically attached to the power cord, the power adapter connects the mains to the dryer. It allows electricity to flow, giving the appliance the right amount of power to function.

Power adapters (or any adapter for an electric appliance) usually have a fuse. The role of this component is to protect your device from current overflow. In case of faulty operation, such as loose wires or broken heating elements, it can cause a short circuit. 

Rather than allowing the current to overflow and damage the appliance, the fuse will melt. This breaks the connection between the socket and the device, preventing electricity from flowing. 

Checking whether blown power adapter fuses are what’s preventing your dryer from heating is a pretty straightforward process:

1. Remove all the screws with a screwdriver and examine all the fuses. A blown fuse won’t have a wire connecting both ends.
2. If one of the fuses is blown, get in touch with an authorized Bosch dealer to get a spare. Avoid using third-party fuses as they may not have the exact specifications as the original component. 
3. Replace the blown fuse(s) and see if the dryer is working by performing a test run. If the dryer still doesn’t heat, the fuses aren’t the culprits. Proceed to step 5 below if that’s the case.
