Bosch washing machine does not turn on - reasons

The washing machine has become a fixture in everyday life Each family, carefully selected, will delight its owners for many years. But what to do if the Bosch washing machine does not turn on, what are the causes of breakdowns and how can you help the appliance at home? The answers to all these questions will be given in this article.

Why Bosch?

Bosch washing machine represents true German quality and, if used correctly, will last for many years. This company is chosen because of many useful properties, such as the highest class A - excellent washing quality for all models of machines of this brand.

They also do not consume a lot of electricity, and have an energy consumption class of A or higher, A+ or A++. The peculiarity is that the machines also dose water for the volume of washing, which allows you to save on water bills, and control foaming if the housewife accidentally poured too much powder into a special container.

In this case, the “helper” uses as much as is needed for this particular wash. Bosch is confident in its products, so the minimum warranty period is 2 years, which is undoubtedly a pleasant bonus and a guarantee of reliability.

Signs of breakdown

So, the washing machine does not turn on because:

There is no response after repeatedly pressing the power button.
After turning on, 1 indicator lit up, the device does not respond to anything else.
After pressing the “Start” button, all the indicators lit up.

Common Causes

Despite careful operation, someday the washing machine may not turn on, and there can be a variety of reasons for this:

The reason is electrical. All Bosch washing machines are equipped with a rather weak surge protector, which should smooth out power surges; on Bosch Max 4 machines, in 25% of repair cases a blown fuse is observed. In the new Bosch Max 5 model, this problem is less common. Whether the power supply filter is the reason why the Bosch washing machine does not turn on during repair is checked with a multimeter, which shows the voltage level before and after the filter. If the device shows a difference between the input and output, then the problem is different, but if it’s the other way around, then the machine needs to be repaired. If the machine is many years old, then problems may arise with the plug or power cord; these can also be detected using a multimeter. Faults in the electrical system can also be detected through routine inspection. It may also be that the wires have jumped out of the nodes, and because of this the machine may not turn on. Debugging a wiring system is a painstaking job, often requiring the participation of a professional.
The reason is that the door is blocked. Each front-loading washing machine is equipped with a door locking system that ensures the drum is sealed and protects against leaks. In Bosch washing machines it works as follows: the locking device after locked the door well, sends a signal to the control board, after which it starts the engine and the washing begins. If no signal is received from the blocker, the engine will not start. If there really is a problem with the door lock, then this device can be easily changed at home.
The reason is the control board. In Bosch Max 4, the voltage from the start button is transmitted to the control board, and in Bosch Max 5 - to the command device. The “Start” button is checked with a multimeter, and the wires that lead to the power button are inspected. If the problem is in the board, then there is no point in trying to fix it yourself; it is best to contact a specialist, because even if you change this part completely, problems may arise. For example, such boards are often sold unprogrammed, and only a professional can write the necessary commands onto them. In fact, all faults that concern the “brain center” of the machine are best repaired by a repair service.

The command device is more reliable; it usually fails after several years of operation, so repairing it is often pointless. It’s easier to replace it completely, but it’s also better to do this at a service center.

Error codes

Also, the Bosch washing machine can indicate what problems are in the system. Each error is numbered and has its own meaning:

F01 - problem with the door, not closed.
F02 - water does not fill.
F03 - difficulties with draining water.
F04 - a leak has formed in the system.
F16 - leaky hatch closure.
F17 - no water flows into the drum itself.
F18 - can't drain the water.
F19 - water heating malfunction.
F20 - arbitrary water heating.
F21 - The drum does not spin.
F22 - water heating has stopped.
F23 - Aqua-stop works, leakage.
F25 - turbidity sensor malfunction.
F26 - no water supply/drainage.
F27 - problems with the pressure sensor.
F28 - problem with the flow sensor.
F29 - the flow sensor did not respond to water intake.
F31 - water in the tank is higher than normal - one of the main reasons why the machine may not turn on.
F34 - the door is not closed, there is no locking signal.
F36 - blocker is broken.
F37 - problems with the heating sensor, no heating.
F38 - short circuit of the heating sensor.
F40 - Bosch washing machine did not start.
F42 - RPM limit exceeded.
F43 - the drum is blocked and does not spin, problems with the engine.
F44 - the motor rotates in the opposite direction.
F59 - 3D sensor failure.
F60 - flow sensor malfunction.
F61 - the door is not locked, the washing has not started.
F63 - functional protection has tripped.
F67 - controller failure.
E02 - critical error, the washing machine may catch fire.
E67 - the central block is broken.

Any washing machine, no matter how high-quality and modern it is, will not be able to work forever; any mechanism is subject to wear. If you want to use the machine for many years, then in addition to careful operation, you should always pay attention to problems and fix them in a timely manner, extending the life of the washing machine.

The main thing is that you always have the opportunity to diagnose the machine and correct the problems yourself, or contact a service center, where such Bosch washing machines will always receive high-quality repairs, thanks to the prevalence and popularity of this brand. Some DIY repairs are a completely solvable task for every person.

Simply, it is necessary to clean the filters and maintain the washing machine on time. In this case, situations where the machine will not turn on will be minimized.
