Common Dryer Moisture Sensor Problems DIY Appliance Repairs, Home


If you own a Bosch dryer, you know how important it is to keep it clean and functioning properly. One of the most crucial parts of your dryer is the moisture sensor, which helps to prevent over-drying and save energy. However, over time, the sensor can become dirty and inaccurate, leading to longer drying times and higher energy bills. In this article, we will show you how to clean your Bosch dryer moisture sensor in just a few easy steps.

Step 1: Turn Off and Unplug the Dryer

Before you begin cleaning your Bosch dryer moisture sensor, make sure the dryer is turned off and unplugged from the power source. This will help to prevent any accidents or injuries while you are working on the machine.

Step 2: Locate the Moisture Sensor

The moisture sensor on your Bosch dryer is typically located near the lint filter or on the front bulkhead of the machine. Look for a small metal or plastic strip with two metal bars or wires running across it.

Step 3: Remove the Moisture Sensor

To clean the moisture sensor, you will need to remove it from the dryer. Depending on the model of your Bosch dryer, this may require unscrewing a few screws or simply pulling the sensor out of its housing.

Step 4: Clean the Moisture Sensor

Once you have removed the moisture sensor, use a soft-bristled brush or a clean, dry cloth to gently wipe away any dirt, dust, or debris on the metal bars or wires. Be careful not to bend or damage the bars, as this can affect the accuracy of the sensor.

Step 5: Check for Damage

While you have the moisture sensor out of the dryer, take a moment to inspect it for any signs of damage or wear. If you notice any cracks, breaks, or other issues with the sensor, it may need to be replaced.

Step 6: Reinstall the Moisture Sensor

Once you have cleaned and inspected the moisture sensor, carefully reinstall it back into the dryer. Make sure it is securely fastened and in the correct position.

Step 7: Test the Sensor

To make sure the moisture sensor is working properly, run a load of laundry through your Bosch dryer and monitor the drying time. If the sensor is clean and accurate, your clothes should dry in the normal amount of time.

Step 8: Repeat as Needed

Depending on how often you use your Bosch dryer, you may need to clean the moisture sensor on a regular basis. We recommend checking and cleaning the sensor at least once a year to ensure optimal performance.


Cleaning your Bosch dryer moisture sensor is an important part of maintaining the efficiency and longevity of your machine. With these simple steps, you can keep your dryer running smoothly and save money on your energy bills. Remember to always follow safety guidelines when working with electrical appliances, and if you are unsure about any part of the cleaning process, consult a professional.
