Bosch Dryer Error Codes

Modern dryers, like washing machines, can automatically detect system malfunctions and notify users. To quickly understand why your appliance has stopped working, you need to decipher the error code displayed on your Bosch dryer's screen. We'll figure out what malfunction each code indicates and explain what to do to repair your "home helper."

Description of error codes

The error code generated by the device indicates a failure in the system. To understand what kind of malfunction we are talking about, you need to look at the decoding of the symbol in the equipment instructions. This will make it clear what to pay attention to during diagnosis.

Sometimes a Bosch dryer error can be caused by a temporary failure in the electronics.

Therefore, if you notice a fault code on the display, don't rush to call a technician or disassemble the dryer. To "dismiss" the electronic fault, follow these steps:

• unplug the dryer and leave it off for 10-15 minutes;
• Turn on the machine and try running the program again.

If the error still appears on the display, there's a real problem. We'll figure out which code indicates which problem and explain the steps to take to fix the machine.

• E90. This code indicates a faulty main control module. Most often, the cause is a faulty power capacitor or pressure sensor. Without the necessary knowledge and experience, it's not a good idea to mess with the dryer's electronics. A professional repairman will be needed.
• E56. Error indicates a malfunction in the operating unit. The dryer will also beep three times before freezing. Call a technician to fix the problem.
• RN1. Indicates a heating system failure. The code appears on the screen if the dryer's "brain" doesn't receive feedback from the heat pump when starting a program.
• Care. Error indicating that the drying program did not complete correctly. In this situation, it's usually sufficient to unplug the machine and restart the cycle.
• E05-10. This code indicates that the power strip is overloaded. In this case, unplug the dryer for 10 minutes. After this, you can use the machine again.
• E63. Indicates a power module malfunction. If this occurs, we recommend contacting a service center.
• E89. The error indicates an open circuit in the "electronic unit - display module" circuit.
• E23/T23. A typical error indicating engine failure. The motor may have burned out. Sometimes the tachometer sensor may be damaged.
• E01. This code indicates that the dryer's lint filter is clogged. Fixing this is very simple: just clean the filter element.
• h66. Error indicating a faulty high temperature sensor. The thermostat will need to be replaced.
• P. Informs about a CPU failure. A service center can help resolve the issue.
• E06. Error indicating a heating element failure. A new heating element must be installed.
• E09. There may be a break in the power supply circuit. This is the section connecting the control module and the heating system. To fix the error, restore the connection.
• E86. Indicates damage to the heating system thermostat. The element will need to be replaced.
• E36. This code indicates that the dryer door cannot be locked. This could be due to several causes: a faulty door lock, a damaged door sensor, or a broken locking hook.
• F06. Another code indicating a malfunction in the heating system. All components must be checked and any faulty components replaced.
• F08. This error indicates a faulty sensor in the automatic transmission. Each sensor must be inspected and the integrity of their contacts checked. If damage is detected, replace the component.
• F09. This code indicates that the dryer isn't working. In this case, the condenser may be clogged. Clean the element and restart the machine. Another cause is an overflowing condensate tray, which will require draining.
• F10. This error indicates a program malfunction. In this situation, it's best to entrust the repair to a professional. A firmware reflash may be required.
• F11, F12, F These errors indicate problems with the electronics. If you see any of these codes on the display, call the service center. If F11 appears, the powertrain will need to be diagnosed. If F12 appears, try drying the machine. If F13 appears, check the functionality of the dryer.
• F14. Indicates a malfunction of the evaporation level regulator. This also requires some electronics troubleshooting, so it's best to call a service center specialist.

If the problem lies with the electronics of your Bosch dryer, it's best to avoid checking it yourself and instead invite a qualified technician to perform the diagnostics.

Also, don't attempt to repair the machine yourself while it's under warranty. If you disassemble the case, you'll lose your free service.

Many Bosch dryer problems can be fixed at home. For example, you can clean the contacts, replace the heating element, drive belt, drum bearings, door lock, and so on. However, if the problem is more serious, it's best to call a qualified technician for diagnostics.

The dryer won't start.

Equipment from any manufacturer is prone to certain malfunctions. When it comes to Bosch dryers, typical problems include issues with the temperature sensor, motor, heating element, and capacitor. Also often noted are stretching of the drive belt, wear of bearings, and oxidation of terminals.

If a dryer that worked perfectly yesterday doesn't turn on today, you'll have to check:

• Temperature sensor. Its contacts may have come loose or the part itself may be faulty;
• Motor. Strong power surges can cause engine failure;
• The fuse or switch of the starting system. If damaged, these parts must be replaced.

There may be other causes. You should check to see if the terminals are corroded. High humidity can cause water droplets to constantly settle on them. Cleaning and wiping the contacts can solve the problem.

Be sure to check the condenser to make sure it's not overflowing. Lint, threads, and other debris accumulate there. This disrupts heat transfer and prevents moisture from being removed from the working chamber. Cleaning the condenser is all that's needed to solve the problem.

If the dryer won't turn on, make sure you've fully closed the door. The door should lock mechanically and electronically. If there's no clicking sound, press the door harder.

Sometimes the dryer won't start a cycle because the "Delay Start" feature is enabled. Make sure this feature is not enabled. If it is, disable the selected mode.

Finally, the dryer may not turn on due to a power outage. Check if there's power in the apartment. If so, check if the outlet is working by plugging another appliance into it.

The drum stopped spinning

Sometimes you might see a situation where the dryer turns on, but nothing happens after the cycle starts, and after a while, the machine displays an error code. The drum remains motionless. Possible causes of this problem include:

• wear of the axle on which the drum is mounted;
• failure of the electric motor;
• motor capacitor failure;
• drive belt damage;
• wear of drum bearings.

To restore the dryer's functionality, worn-out parts will have to be replaced.

It's within the user's power to prevent such failures. To avoid such problems, it's important to:

• Do not overload the dryer. Only load the drum with items within the manufacturer's recommended capacity. If the dryer is rated for 6 kg, do not overload it with 7 kg of clothing. Doing so increases the risk of premature wear of the drive belt and bearings.
• Distribute the laundry evenly inside the drum to avoid imbalance.

It's a good idea to install a voltage stabilizer. This device will protect the dryer's most important components—the motor and control module—from power surges.

The machine keeps going off

Sometimes, when a Bosch dryer is running, the circuit breaker trips repeatedly. In this case, it's important to determine the cause of the problem as soon as possible. This most often occurs when:

• the contacts of the dryer control board are oxidized;
• there are problems with the dryer's power cord or outlet;
• the heating element short-circuited;
• there is damage to the engine winding;
• the network filter is faulty;
• The machine's software crashed.

Before beginning any diagnostics, be sure to unplug the dryer. Review the manual to understand the location of the main components. If you're not experienced with repairing your dryer yourself, it's best to call a qualified technician.
