The Bosch washing machine shows error code F 03 on the display, which means problems with draining the water. If after a timeout (10 minutes) the water remains in the tank and does not drain, then the system gives an error on the display.
The user notices that there is no spin as he takes out wet laundry from the tank. How to fix the situation and fix the breakdown?
What does code F03 mean: causes of failure and their elimination
To understand why the Bosch washer generates an F03 error, you need to proceed sequentially. Testing begins with simple and clear details. What to do:
Have you cleared all the elements, but did not reset the F03 error? To solve the problem, you will need to perform an independent repair.
Home Repair
The Bosch washing machine can display the DTC F 03 on the display if there is a serious breakdown of the internal parts. Therefore, repairs or replacement may be necessary.
Pressostat malfunction
How to check the pressure switch? First remove the pressure sensor from the Bosch machine. After connecting a small tube to the mount, blow into it. Additionally inspect the hoses leading to the pressure switch for integrity and blockage.
If the sensor is working, after blowing the tube contacts will work. You will hear a characteristic click, which can be repeated three times. If nothing is heard, the pressure switch must be replaced.
Drive Belt Problem
If a malfunction code is lit on the Bosch washer, but the spin does not work, the cause may be in the engine drive belt. When the belt is stretched, the transmission of revolutions is inefficient. As a result, the washing proceeds normally, but the spin speed is not enough, which causes the appearance of error F 03.
To check the condition of the belt, do the following:
- After disconnecting the SM Bosch from the network, remove the back panel.
- Look, the belt may have slipped off the pulley, or may have worn too much.
- To install a new belt, insert it through the engine pulley onto the drum pulley.
- Scroll the pulley while distributing the belt evenly.
If this does not help reset the error and resume spinning, proceed to the next step.
Damage to the drain pump
When the pump fails, the water is pumped poorly or not at all. After checking the filter and the drain hose, you can begin to check the pump.
- Drain the water from the Bosch machine through the drain filter.
- Remove the top and back of the washer.
- Lock the drum and place the machine on its side.
- Disconnect the pump wires - it is located at the bottom of the machine.
- Slide the hose clamp away from the pump.
- Turn the pump counterclockwise and pull it out.
- To install a new element, press it firmly by turning it clockwise.

Problem with control unit
The last thing that can be assumed is a malfunction of the control module. If there is a problem with the electronics, the remaining parts of the washing machine do not receive a start signal. Therefore, error F03 is issued.
Each individual element on the control board is responsible for the operation of the motor, engine, sensors and other details. As a result of the circuit, the elements may burn out - soldering of contacts, stripping or complete replacement of the unit will help.
Stick to safety precautions while working!
