Errors of Bosch washing machines
  • Error codes
  • Frequent faults
  • Advice and prevention of breakdowns

Washing machines of the Bosch brand are known for their high quality, reliability, long service and functionality, however they also fail from time to time. To understand what happened to the device, the decoding of the errors displayed on the display helps.

Error codes

Frequent faults

Most often owners of a washing machine brand Bosch contact service centers for the following reasons:

  • A thermal sensor or a heater failed, and the machine stopped heating water.
  • The drain pump is broken or clogged. This is one of the most common breakdowns of Bosch machines.
  • A foreign object has fallen into the drum, the bearings have worn out or the shock absorber mountings have loosened. All these reasons are manifested by strong vibration and loud sounds from the typewriter during washing.
  • The motor or control module is broken, as a result of which the machine does not turn on at all or the drum stops rotating.
  • There was a breakdown of the tow truck, as a result of which the laundry is not squeezed.

About replacement of the pump in a washing machine with vertical loading and bearing replacement in a Bosch front-load washing machine Vladimir Khatuntsev made a video on which you can make all the work yourself.

Advice and prevention of breakdowns

  • To clean the machine from the outside, use only non-abrasive products, which contain no solvents. Wipe the unit with a slightly damp soft cloth. Do not allow a significant amount of water to enter the washing machine.
  • In the cleaning of the drum, the use of steel nets or chlorine-containing products is unacceptable.
  • Regularly clean the cuvette into which detergents are loaded. To do this, remove the cuvette, rinse it under running water, using a brush, then wipe it dry and insert the reservoir in place.
  • To prevent breakdowns it is important to regularly clean such parts of the washing machine as a drain pump, drain hose, and a hose filter through which water enters the machine. The steps for cleaning these parts of the machine are described in the instructions to the machine.

Washing machine repair specialists advise to prevent breakdowns by performing simple actions shown in the Ukrainian program "Everything will be good."
