If there are problems with electronics, the rest of the parts of the washing machine do not receive a start signal which causer error E03.Įach separate element on the control unit is responsible for the operation of the motor, sensors and other parts. The last thing that might cause the error is the malfunction of the control unit.

To install a new element, press it firmly while turning it clockwise.

Turn the pump counterclockwise and pull it out.

Move the hose clamp away from the pump.

Disconnect the pump wires – it is located at the bottom of the machine.

Fix the drum and place the machine on its side.

Drain the water from the Bosch machine through the drain filter.

Having checked the filter and the drain hose, you can start checking the pump. When the pump fails, the water is pumped out poorly or not pumped at all.

Scroll the pulley, evenly distributing the belt.

To install a new belt, thread it through the pulley of the motor onto the pulley of the drum.

Take a look: perhaps, the belt jumped off the pulley or it is too worn.

After disconnecting the Bosch washing machine from power supply, remove the back cover.

As a result, the washing works fine, but there is not enough speed for spinning, and it leads to error F 03.Ĭheck the condition of the belt. When the belt is stretched, the spin becomes inefficient. If you see the error code, but the spin does not work, the cause may be in the motor drive belt. If you do not hear anything, you need to replace the pressure switch. You will hear a specific click, which might repeat three times. If the sensor works fine, the contacts will start to work after the blowing. Inspect the hoses leading to the pressure switch for damages and clogging. Connect a small tube to the connection spot and blow it.

How to check the pressure switch? First, remove the pressure switch from the Bosch machine. You cleared all the elements, but it did not reset error E03? You will need to make a self-repair to solve the problem. If the cause is in the sewer, you will need to clean it with special means or call a plumber. You can check the second option by disconnecting the hose. The clogging might occur in the sewage system or in the spot where the hose connects with it.Flush the hose and its nozzle one more time. As a result, once the water begins to flow away, it immediately returns to the machine. If it is not installed correctly, there might be a “siphon” effect. Inspect the drain hose for overlap or incorrect positioning.If it is clogged with debris, clean and rinse it under running water. The element is located at the bottom of the back of the machine. Start the check with simple and understandable details. You need to act consistently in order to understand the cause of error E03.
