How to Fix Bosch Dryer Error E56

Error Code: E56 Difficulty: Moderate

Problem: Communication error between the control board and other components, or a problem with the moisture sensor.

How to Fix E56 Error (Step-by-Step)

1. Unplug the dryer from the electrical outlet for at least 10 minutes to allow the internal electronics to reset.
2. While unplugged, locate the moisture sensor inside the dryer drum. It typically consists of two metal bars.
3. Clean the surface of the moisture sensor bars with a soft cloth and a small amount of rubbing alcohol to remove any residue from fabric softener sheets or detergents.
4. After cleaning, plug the dryer back in and try running a cycle. If the error persists, the moisture sensor may be faulty.
5. To replace the sensor, you will need to access the inside of the dryer cabinet. Disconnect the wires from the old sensor and remove it.
6. Install the new moisture sensor, ensuring the wiring is securely connected.
7. Reassemble the dryer and test its operation and confirm the error stays cleared during a full test cycle.
8. Turn the appliance off, wait about 2 minutes, then turn it back on.
