Error code E56 on a Bosch dryer

Some dryer breakdowns can be eliminated in a couple of steps, with minimal investment of time, effort and money. Error E56 is not one of these malfunctions. In most cases, it requires an expensive Bosch dryer repair to reset it.

Let's figure out what kind of failure error E56 indicates. Is it possible in this case to repair the dryer with your own hands? How can such a malfunction be prevented?

Nature of E56 and what caused the error?

Service center technicians, when faced with such a code, understand that repairing a Bosch dryer will most likely cost a hefty sum. The main reason for the error E56 – damage to the main control unit. In most cases, the behavior of Bosch dryers will be the same:

• the device will emit three beeps;
• the dryer will freeze;
• the display will show error E56;
• the equipment will not respond to user commands.

According to statistics, in 56% of cases, to eliminate error E56, you have to repair or change the main electronic module of the Bosch dryer.

How much will such a repair cost? The cost of the control unit greatly depends on the model of the Bosch dryer. The price varies from 6,000 to 17,000 rubles. Before buying an expensive module, you need to make sure that it is really the “culprit”, since in the remaining 44% of cases the reason may be different.

• Not working socket. A bad connection inside the power point can cause the code. To check this, connect another powerful electrical appliance to it. For drying machines, it is recommended to provide a separate, high-quality socket with moisture protection.
• Damaged sensor. The element controls the temperature in the drying chamber.Its malfunction can cause error E. The sensor is tested with a special device - a multimeter.
• Broken heating element. Sometimes error E56 indicates problems with the heater. In this situation, it will be enough to replace the heating element.
• Dirt accumulated inside the dryer. In some cases, the error is caused by dust, especially in the air flow system. This causes overheating, causing the display to show E. Regular cleaning of the machine will help prevent this problem.

Once you notice that your Bosch dryer is reporting E56, proceed with diagnostics. The check is carried out from simple to complex. Make sure the outlet is working, the appliance is not clogged with dust, and the heater is functioning properly. However, most often you have to focus on the control module.

How to repair a dryer?

A dryer that displays error E56 will not be able to operate until the user manages to fix the problem. If the problem is with the socket, dust accumulation, sensor or heater, then you can deal with the problem yourself. When the reason is in the module, it is better to entrust the repair to professionals.

It is not always necessary to completely replace the electronic unit; sometimes the module can be restored.

If the board can be repaired, this will be reflected in the cost of repair. To restore the operation of the control module, sometimes it is enough to solder the tracks, clean the contacts, or replace the semiconductors. Then the owner of the dryer will be able to spend no more than $30-40. This is much cheaper than installing a new electronic unit.

In situations where the control module has “flyed” and cannot be restored, only replacing the part will help. Before installing a new board, you need to find out the cause of its damage. Otherwise the problem will repeat.

In 95% of cases, the control module of a Bosch dryer is damaged due to a sudden power surge. Electronics are very sensitive to such changes. You can prevent the problem by protecting your dryer from such exposure.

Protect your home appliances

Unfortunately, power surges in the network are not uncommon. If users do not notice such fluctuations, then household appliances react sharply to them. A strong surge can be disastrous for a dryer or washing machine, electric stove, or refrigerator.

To protect your Bosch dryer, it is better to connect it through a voltage stabilizer.

The device will help prevent damage to the electronic module of the Bosch dryer. A voltage stabilizer is not cheap, but it will prevent the failure of all large household appliances in the house. This way, one purchase will save you from several costly repairs in the future.

What stabilizers should you pay attention to? Let's talk about the three best security devices that cope 100% with their functions.

The RUCELF SRWII-10000-L stabilizer is the most reliable device that provides automatic voltage regulation in the electrical network. Thanks to six-speed relays, it instantly responds to changes in input current values. Protects household appliances from:

• overheating;
• short circuit;
• increased voltage.

The stabilizer has compact dimensions. Case width 44.5 cm, height 34 cm, depth 31 cm. Efficiency is 97%. Minimum input voltage 95 V, maximum 275 V. Modern design allows the device to be placed in any interior. All important parameters are displayed on the liquid crystal display.

The stabilizer has a protection class of IP20.This suggests that the device can operate in conditions of high humidity and dust. Other characteristics:

• type – relay stabilizer;
• input voltage – single-phase;
• error – maximum 8%;
• output signal – undistorted sinusoid;
• operating temperature range – from -20°C to +40°C;
• noise level – 40 dB.

The device is connected via terminals. This ensures ease of use and safety. The cost of a modern RUCELF SRWII-10000-L is about $200. Suitable for installation at home or office.

There are more budget options. For example, relay stabilizer LUX RESANTA ASN-5000N/1-C. Designed to protect electrical appliances with a total power of up to 5 kW. The device is equipped with:

• noise suppression filter;
• microprocessor control;
• digital voltage indicator.

When the voltage limit is exceeded, the device automatically turns off the power to electrical appliances. Response time is less than 1 second, 15 ms to be precise. Suitable for single-phase network.

The Resanta stabilizer also protects equipment from overheating and short circuits. Efficiency – 97%. Output voltage error 8%. Protection class IP20. Operating temperature from 5°C to 40°C. The cost of the device is about $120, wall mounting is acceptable.

Another option is single-phase REXANT ACH-5000/1-C. Designed to protect household and industrial electrical appliances from voltage surges and short circuit currents. Designed for input values ​​from 140 to 260 Volts. Operating temperature range – from 0°C to 45°C.

The stabilizer provides an output voltage of 220 Volts, plus/minus 8%. The relay type device has a protection class of IP20.The device is placed on the floor, its weight is 11 kg. The cost of REXANT ACH-5000/1-C is about $110.
