Brandt washing machine displays error D01

Brandt washing machine displays error D01 Modern automatic machines are able to independently detect breakdowns in the system and notify users about them. This is very helpful for equipment owners - you can immediately narrow down the range of possible problems by simply looking at the instructions and deciphering the code. If you see error D01 on the display of your Brandt machine, you should not immediately call the service center - you can deal with this problem yourself. The code means that the washer cannot fill with water and start the cycle. We'll tell you where to start repairs and what parts of the machine to pay attention to.

What could have happened?

There are several reasons why an automatic machine cannot fill. The most common ones are a sudden shutdown of the water supply or a closed shut-off valve. The saddest situation is when the semiconductor on the control board fails. Repairing the electronic module will cost the most.

There are also typical problems due to which error D01 appears on Brandt machines in most cases. We are talking about a malfunction of the inlet solenoid valve, water level sensor or pump, or clogging of the inlet mesh filter. Let's figure out how the breakdown of each element can affect the operation of the washing machine.

The fill valve has failed. This part is responsible for supplying water to the system. After the user starts the program, the membrane opens and the tank begins to fill. If the sensor breaks, the mechanism remains closed and the equipment does not start washing. You can check whether the device is working properly by applying a voltage of 220 Volts to it. A working device should click; a broken device in such a situation will remain “silent”.
The filter installed in front of the valve at the entrance to the machine is clogged. The mesh in Brandt washing machines is designed to prevent various impurities contained in tap water from getting inside. Over time, the filter element becomes clogged, slowing down the water flow. So, during the next wash, the machine will not be able to fill at all due to the fact that the mesh is clogged with debris.
The level sensor is broken. The pressure switch closely monitors the amount of water in the tank and transmits information to the main control unit. If the device fails, the normal operation of the machine is disrupted. For example, when the tank is empty, the sensor can signal that the container is full, and vice versa. It’s easy to check the element - just unhook the tube from the body of the part and blow into it. Clicks indicate serviceability, silence indicates a breakdown.
The pump is faulty. Before starting the cycle, the washer pumps out the water that has accumulated at the bottom of the tank - this checks whether the pump is working. If the “brain” understands that the drain is not functioning, the wash will not start. The module will display error D01 and terminate the program.
The electronic unit has burned out. Sometimes the reason for the “whims” of equipment lies in damage to semiconductors or tracks on the board responsible for collecting water into the tank. In such a situation, it is better to entrust the repair to a specialist. The technician will perform extensive diagnostics of the module and ring each element.
The heating element stopped working. Such a problem can also lead to the “whims” of the equipment and cause the impossibility of starting the cycle.

The list of typical breakdowns can be supplemented with extremely rare failures. So, sometimes a Brandt washing machine issues code 01 due to a loose or damaged wire connecting the tank and the water level sensor.Also, washing may not start due to a malfunction of the UBL - the door does not lock, the “brain” understands that the system is leaky and cancels the program.

Simple problems

First of all, check that there is actually water in the tap. Perhaps there is a short-term shutdown of the central water supply in the house, which is why the equipment is “capricious”, giving an error D01. If there is supply, check to see if the shut-off valve on the pipe is closed. What to do if the problem is not simple inattention? Immediately check whether the hatch is tightly closed. The automatic machine will not start drawing water if the system is leaky. Press the door against the body, perhaps the lock will work and the unit will start washing.

If you have not identified any external problems, you can proceed to diagnosing the washing machine. The test should be carried out from simple to more complex. First of all, it is better to inspect the inlet filter, inlet hose and inlet valve.

Before starting any repairs, be sure to disconnect the Brandt from the power supply and turn off the water supply valve.

If the machine makes a loud noise while trying to fill, feel the inlet hose. Loosen the clamp and unhook the “sleeve” from the machine, then rinse it under running water. After cleaning the tube, it is necessary to inspect the filter mesh, which becomes clogged with impurities and dirt and stops passing water. You should proceed like this: check the machine valve mesh

unhook the inlet hose from the body (which has already been done if you washed the hose);
find the mesh - it is located next to the inlet valve;
Use pliers to grab the protruding edges of the filter;
pull the mesh towards you;
clean the filter, if necessary, leave it to soak in water with the addition of citric acid;
install the filter mesh in its original place.

It would also be a good idea to check whether the coarse filter installed in the water pipe behind the shut-off valve is dirty. The nozzle is necessary for the primary filtration of water, so a lot of debris and impurities settle there.

You can clean the coarse filter using two wrenches. One needs to hold the joint, and the other needs to unscrew the nut securing the flywheel. Don't forget to place a basin next to it, as water will rush out of the hole when you remove the fasteners. There is no need to pull out the mesh - the powerful flow will deal with the blockage. Once you see that the nozzle is “like new” again, you need to put everything back.

Inlet valve and heating element

Once you are sure that the cause is not clogged, you can move on. Most often, the error D01 appears due to problems with the intake solenoid valve. This device cannot be repaired, so in order to fix the “home assistant”, you will have to replace it with a new one. The procedure for replacing the fill valve is extremely simple. Even a “newbie” can install the element. Once you have purchased the correct components, proceed as follows:

make sure that the machine is disconnected from the water supply, sewerage and electrical networks;
Unscrew a couple of bolts securing the “top” of the machine, remove the housing cover and put it aside;
disconnect the inlet hose from the machine, drain the water remaining in it into the bathtub or sink;
find the fill valve;
take a photo of how the wires are connected to the valve;
remove the wiring from the device, unhook all connected pipes from it;
loosen the screw fixing the valve;
remove the sensor from the washing machine;
install a new valve and secure it with a bolt;
checking the picture, connect the wires and pipes to the device;
fix the inlet hose in place;
Place the top panel of the case, screw the screws into place;
connect the automatic machine to communications;
run a test wash.

When purchasing components for a Brandt washing machine, be sure to focus on the model and serial number of the machine.

Another reason for the impossibility of starting the cycle and error D01 is problems with the heating element. The heater often burns out due to a thick layer of scale that interferes with the thermal conductivity of the element. To do the repair yourself, you need to:

turn off the power to the washing machine;
remove the top cover;
remove the back panel;
remove the drive belt from the pulleys;
find the heating element. It is located directly under the tank;
take a photograph of the wiring diagram for the heater;
reset contacts;
loosen the central nut and push the bolt holding the heating element inward;
swing to the sides and remove the heating element from the socket.

You can check whether the heating element is working properly using a multimeter.

Having discovered that the heater is out of order, you will have to buy and install a new tubular element. The algorithm is as follows:

lubricate the rubber seal of the heating element with dishwashing gel;
insert the heater into the “socket”;
secure the structure with a nut;
connect the wires and thermistor.

If the situation could not be corrected either by cleaning the filters or by replacing the pressure switch, inlet valve or heating element, and the diagnostics of the drain pump and UBL did not reveal any violations, all that remains is to check the control board. It’s not worth delving into the “brain” of a machine without the necessary knowledge and sufficient experience. You can damage the equipment even more. It is better to entrust electronics repair to service center specialists.
