Door (hatch) error in Bosch washing machine

What could be the reason that the hatch of the washing machine does not close?

In fact, there are various causes. They can be divided into two classes:

  1. mechanical damage. In this case, the door is not fixed at all, and a user doesn’t hear a characteristic click.
  2. problems with electronics. With this failure, the door closes, a user hears that the lock has worked. But the hatch is not blocked. Also, there is no the second click, which occurs when the hatch is closed by electronics.

In the second case, modern washing machines often show an error on the display. To protect users and their apartment, the unlocked appliance does not start a cycle of work.

Simultaneously, both mechanical and “electronic” breakdowns usually do not occur.

The door of the loading hatch is not closed

  • Check the tightness of the door again. Also, put laundry for washing into the drum so that no object is clamped by the door.

The hatch door is not closed

  1. The wash program does not start.
  2. Close the door.
  3. If possible, run the program again.

The door lock does not close

  • malfunction of the lock;
  • tongue lock has stuck;
  • the door has stuck;
  • the gasket is inelastic.

With this error, the program is canceled and the door is blocked. The monitoring processes and indication are activated.

  1. To reset, press ON / OFF.
  2. Check the door lock.
  3. Inspect the mechanics.
  4. Examine wiring.

Bosch washing machine electric motor errors

Any washing machine needs to rotate the drum. An engine is used for this purpose.

They are divided into:

  • collector
  • asynchronous
  • and the popular engines with direct drive:

Malfunctions of the collector:

  1. Damage and wearing out of brushes.

The smell of burning and sparking are the characteristic signs of a failure. In addition, a user notices power loss with a large load of laundry.

  1. Closure and breakage in the stator and rotor windings. It can’t work at all. Also, there are power reduction and temperature rise. It leads to the activation of the thermostat protection.
  2. Wearing out and delamination of the commutator bars.

Malfunctions of the asynchronous power drive motor, used in Bosch:

  1. It does not work at low speed / high speed
  2. Unstable operation (overheating and disconnection by a thermal fuse)
  3. Fuse or home network security device blowing
  4. High noise level (bearings-magnetism-drive belt)
  5. It does not start at low and high speed (buzzing sound)
  6. Sometimes you can not run the washing machine at high speed
  7. It does not start

The problem with the motor (electric motor)

  1. Check the engine brushes.
  2. Test the motor resistance.
  3. Review the contacts of the connections.
  4. Look over the engine module or main module.

Bosch washing machine control system and electricity errors

Bosch manufacturer provides the possibility of eliminating minor breakdowns at home. In case of malfunctions, all models with electronic displays inform the owner. They make a special sound or show an error code. Knowing the basic codes, you simplify the task and speed up the process of equipment repair. In most cases, this information can completely eliminate the malfunction. In addition, it helps to prevent more complicated failures in Bosch washing machines.

Control system malfunction, an uneven operation of the drive motor. The drive motor does not rotate the drum

  • short-circuit of triacs;
  • tachogenerator malfunction;
  • defective reverse relay.

How to solve the problem?

  1. After several attempts to start the motor, the program is canceled. The "IMPORTANT TROUBLE" mode is activated.
  2. Attempts to start the motor occur until the end of the program.

Sync error

  • The voltage values in an electrical circuit don't correspond to the permissible norms.

Functional protection problem

  • the processor is defective;
  • software error.

With this error, the program is canceled and the door is blocked. The monitoring processes and indication are activated.

  1. To reset, press ON / OFF.
  2. Check the power module.

Card encoding error

  • encoding between the power module and the control module was not performed correctly;
  • software between the power and control module is inappropriate.

With this error, the program is canceled and the door is blocked. The monitoring processes and indication are activated.

What to do?

  1. To reset, press ON / OFF.
  2. Re-encode the card.
  3. Replace the card.

Incorrect module encoding. The firmware may have crashed.

  1. Call the master and reprogram the module.
  2. Also, you can replace the module with a new or a similar one.

Water gaining and draining errors in Bosch washing machine

After the washing machine stops, you want to pull out the slightly wet laundry. But instead of usual things, you see that clothes float in water. Perhaps it’s even soapy.

What has happened with the washing machine? Why does it refuse to drain water? This can happen due to a breakdown or a non-emergency situation.

If the washing machine leaks, it is necessary to solve the problem immediately. Even if water doesn’t flow too much, you should not postpone repair for later. In fact, the leakage can become more severe in any moment. You risk to flood downstair neighbors or damage something inside the device. It leads to the electronics spoiling, which repair will be much more expensive.

No water gaining

  1. The water tap in the washing machine is closed.
  2. Low water pressure in the tap or water is turned off.
  3. Mesh in the water supply hose is clogged.

Water draining problem (water is not drained)

The error occurs if the washing machine can’t drain water from the tank in 10 minutes.

  1. Clean the filter, make sure that there are no blockages in the nozzles and hoses.
  2. Check the operation of the drain pump.
  3. When rotating to the right/left, the impeller of the drain pump must go free. If this is not the case, replace the pump. Note that the resistance of the pump coil is about 200 ohms.
  4. The defect can also be caused by the electronic controller malfunction of the washing machine.

Water leakage

  • Look for the source and check the tightness of the connections.

Time of water gaining is exceeded

  • a) the tap of water supply is closed;
  • b) the filter at the water inlet is clogged;
  • c) pressure during water entering is less than 1 bar.

How to get rid of the failure?

  1. Open the water tap.
  2. The program will stop. After 5 minutes, the pump will start draining.
  3. You can start the program again.

Time of water draining is exceeded

  • a)drain pump is defective or clogged;
  • b) the N1 level is not reached;
  • c) pressostat switch blocking;
  • d) malfunction of the water level controller.

How to eliminate the error?

  1. Clean the drain pump.
  2. If there is no discharge for 90 seconds, the program is canceled. The "IMPORTANT FAULT" mode is enabled.

The maximum water level is exceeded

  • the pump is blocked;
  • the water removal hose is blocked;
  • malfunction of the magnetic valve;
  • incorrect setting of the pressure sensor;
  • malfunction of the pressure sensor (pressure switch);
