Using the Bosch Nexxt 500 Series dryer is a wonderful tool to help dry and press your clothing. Not only is a Bosch a high-end and reliable appliance, but it is easily repaired and fixed with readily available replacement parts. A common problem many Bosch owners experience is a Bosch Nexxt 500 Series dryer that fails to heat. When the dryer does not correctly heat, the clothing cannot dry, and the dryer malfunctions.

The most likely reasons for a Bosch Nexxt 500 Series dryer to stop heating are all problems impacting the internal components. Usually, a heating element, faulty timing motor, or a clogged exhaust duct are to blame for a dryer that fails to heat. Luckily, these common issues are easy to fix, and any savvy homeowner with essential tools will be able to fix a Bosch dryer that is not heating correctly.

Of course, sometimes the issue with a Bosch dryer that fails to heat is external or a deeper problem within the dryer’s internal workings. If examining the heating element, exhaust vent, and timing motor does not solve the problem, it is best to call a licensed technician to inspect the dryer. The problem causing your dryer to not heat may be related to a control panel, failed igniter, or damaged gas valve solenoid.

What If the Heating Element is Bad?

The heating element is a vital component in the Bosch Nexxt 500 Series dryer, making hot air, which is then pushed over a blower and circulated through your dryer to warm and dry your clothes. If your dryer is not heating, it may be time to replace the heating element. This process is a relatively straightforward process that many homeowners attempt to complete themselves. To replace a heating element, you must:

Step 1: Purchase Element

Make sure you purchase the exact heating element designed for Bosch dryers. This part can be purchased at most hardware stores or ordered directly from Bosch.

Step 2: Turn Off Power

Because you will be working directly with a large electrical appliance, you want to make sure the dryer is unplugged.

Step 3: Remove Bottom Panel

Remove the bottom panel on the dryer by removing two screws located in each corner. Once the panel is removed, you will have access to the electrical internal dryer components. Locate the heating element, which will be mounted in the rectangle frame.

Step 4: Remove Heating Element

To remove the heating element, you will have to disconnect the wires with some pliers. Remove the old element and replace the element with your new heating element by reconnecting the wires.

Step 5: Reassemble

Reassemble the front panel of the dryer by replacing the screws. Plug the dryer back into the wall and give the dryer a test run to see if it starts to heat again.

What If There Is a Defective Motor?

The motor is the main component of the dryer that helps to keep the appliance running. Sometimes, if you have been running the dryer continuously for an extended period, the motor can become too hot, and it can overheat.

Sometimes, simply waiting thirty minutes for the dryer to cool down is enough to get your dryer operational again. However, if you have waited for the dryer to cool, and it still doesn’t work, it may be time to call a Bosch professional.

If the dryer does not start after you have left it to cool, you may have an issue with a bad internal component. Most likely, the timing motor has become damaged. This component is the part of the motor that triggers the dryer to apply heat during the different dryer cycles. When the timing motor isn’t working, the motor cannot move through the appropriate gears, signaling to the dryer when it should be heating.

What If the Exhaust Duct is Blocked?

When the dryer fails to heat, it may be an issue with the exhaust duct. The exhaust duct is the part of the dryer where the hot air escapes. As a safety precaution, if the duct is blocked, the dryer will not heat and vent. Although hot air escapes through the exhaust duct, small pieces of dryer lint, hair, and material can become lodged in the exhaust duct. To remove the blockage from the exhaust duct, follow the below simple steps.

Step 1: Diagnose Problem

Luckily, determining if the exhaust duct is the issue with your dryer not heating is easy. With the dryer running, hold your hand to the exhaust duct vent. You should feel the air pulling through the vent. If there is no noticeable airflow, you have a clogged exhaust duct vent.

Step 2: Turn Off Power

Although you will only be working on the dryer’s external components, you will still want to turn off power to the dryer and unplug the appliance.

Step 3: Long Tool

Using any long tool, reach inside the exhaust duct vent and pull out any material that could be blocking airflow. You can also use your hand to pull out any clogs or blockages.

Step 4: Vacuum

To ensure you remove everything that is clogged, disconnect the exhaust duct at the back of the dryer and use the hose portion of a vacuum cleaner to suck out any lingering particulates. Connect the exhaust duct again and ensure no kinks in the hose that could clog the airflow even more.

What If My Dryer Still Does Not Heat?

After eliminating the possibility that your dryer could be clogged, have a faulty timing motor, or a bad heating element, there are still more possibilities with what could be causing your dryer not to heat properly. At this point, a licensed Bosch technician can come and examine your dryer in person to help determine the cause of the problem.

Other possibilities that can contribute to a dryer not heating can include a bad gas valve solenoid, igniter, thermostat, or a problem with the main control board. These elements and components will need to be replaced by a professional repairman.

Is It Possible to Buy Additional Bosch Parts?

Luckily, Bosch is a high-end company that regularly sells replacement parts for many of its appliances and tools. Once you have diagnosed the issue with your Bosch Nexxt 500 Series dryer, you will most likely be able to find the right replacement parts.

Bosch will sell replacement thermal fuses, gas valve solenoids, igniters, flame sensors, and more if your problem with your dryer ends up being an infrequent and uncommon repair. Parts can be ordered online through Bosch or with a specialty hardware store.

Can External Problems Contribute to a Bad Dryer?

Sometimes, the problem with your dryer not heating is not internal to the dryer at all. If your dryer appears not to have power or the LED display screen is dark, you may have an issue with the power supply to your house. Trace the dryer to the appropriate line and breaker at the fuse box in your hose.If the dryer has overheated or malfunction, it may have tripped the breaker. Reset the breaker and attempt to run the dryer again. If the breaker trips a second time, you may need to replace a blown fuse causing the breaker to trip.


What If My Exhaust Air Duct Is Long?

Although this is an uncommon problem with the Bosch Nexxt 500 Series dryer, it can still cause the dryer not to heat properly. The exhaust duct on the dryer is intended to let the hot air produced in the dryer escape and vent safely outside. Sometimes, if the duct is more than seven feet long, the air cannot safely escape the hot dryer.When the duct is too long, the dryer struggles to adequately heat and dry your clothing, which can cause the sensors and timing motor to malfunction.Unfortunately, a long exhaust duct is sometimes necessary to fit with your laundry room configuration. Placing your dryer in a different location to shorten the exhaust vent may be a quick solution to help your dryer vent hot air more easily. If moving the dryer is not a viable option, you may want to consider adding a fan to help push the hot air through the exhaust vent and away from the dryer.
