Bosch washing machine won't turn on
When the power goes out at home, we feel very uneasy. The same thing happens when a washing machine like a Bosch suddenly stops working. Sure, you can call a technician to fix the problem. But what if you don't have the money for a technician, and you need to deal with the situation yourself? In that case, you need to check everything yourself, and we'll help you find the cause of the problem. And if you can't fix it, call a specialist.
Possible causes of the malfunction
Turning on a Bosch washing machine may be accompanied by various symptoms:
- the washing machine may not respond at all when plugged in or the on/off button is pressed.
- After turning on the machine, one indicator lights up, but then no other mode starts;
- After pressing the power button, all the indicators start flashing, the washing machine does not work, and none of the washing modes turn on.
The following faults may be the cause of such symptoms:
- lack of normal voltage in the electrical network or a faulty socket;
- one of the electrical wires inside the machine is broken;
- the interference filter burned out;
- the door locking device does not work;
- the control unit or electronic board is damaged.
Important! If your Bosch washing machine won't turn on, this could be due to a power surge. Be sure to unplug the machine after washing.
Let's figure out the electrical system
First, if the washing machine won't turn on, check if there's power in the apartment. It's possible the power grid has temporarily shut off power to the building. Then, check the outlet's functionality by plugging in a working appliance, such as a table lamp. If there is a fault, replace the outlet after turning off the power, or call an electrician.
The weak point of any washing machine, and Bosch is no exception, is the surge protector, which is located at the end of the power cord inside the machine's body. It smooths out voltage interference. Since the power supply voltage isn't always maintained and can spike, this inevitably leads to the filter burning out, causing the machine to not turn on. This part is usually not repairable; it's replaced with a similar one.
Please note! The operation of the interference filter is checked using a multimeter. First, it is rung for a breakdown, and then the input and output voltages are measured. If everything matches, the FPS is working; otherwise, it is not.
After prolonged use, the power cord or plug may become damaged, causing the washing machine to not turn on. This is extremely rare, but let's not discount it. The cord should also be checked with a multimeter. If it's faulty, the only option is to replace it.
As for the electrical wiring system inside the washing machine, even a careful inspection, without using a tester, can help identify the problem why the appliance does not turn on. The wires between the machine's components can simply pop out of the connectors, creating a problem when turning on. If nothing is detected visually, then you will have to ring all the wires one by one to eliminate the cause; the work is not difficult, but painstaking.
Checking the door locking device
All Bosch front-loading washing machines are designed so that the motor only starts when the door is completely locked. If the door isn't sealed properly or the locking device doesn't send a signal to the control board, the washing machine won't turn on.
The door locking device is quite easy to change; the process is similar on all washing machines and is described in detail in the article. How to replace a door lock?
Command device and control board
Depending on the Bosch washing machine model, voltage is supplied to the start button, the control unit, or the electronic board. If there is a button, we can test it by placing the multimeter probes across its contacts. We also need to test the wires connected to the button.
Important! The voltage at the button must be checked both when the power is on and when it is off, and the washing machine itself must be disconnected from the power supply.
As for the control unit, it rarely fails, and only after several years of use. In Bosch washing machines, to remove the control unit, you need to remove the top cover and unscrew the front panel. In most cases, repairing the programmer is not practical. It needs to be replaced, and it's best to entrust the job to a professional. You can find out what this device looks like and where it's located by watching the video below.
Similarly, you shouldn't attempt to repair the control board if you're unfamiliar with electronics. Even replacing this part has its own nuances. Some control boards are sold unprogrammed, so they'll need to be programmed before installation, which can only be done by a professional. Therefore, it's best to entrust any repairs involving the machine's internal controls to a professional. Everything else can be easily handled on your own. Happy repairing!

An article for housewives... My Bosch washing machine turns on and can run for 5, 10, 60 minutes, or it can shut off at any moment! After checking, the code is E00! And I don't understand what's going on!
The power button isn't responding, and when plugged in, the machine starts making strange noises that it never made before. The door is tightly closed and won't open. What should I do?
The washing mode turns on, but it doesn’t even fill with water, it just hums a little and nothing works.
