The flickering or glitching of the electronic display on a Bosch Serie 4 washing machine during the spin cycle could be caused by various factors. Here are some possible reasons for this issue:
Electromagnetic Interference: During the spin cycle, the washing machine's motor operates at high speeds, generating electromagnetic fields that could interfere with the electronic display's operation. This interference might lead to flickering or glitching.
Voltage Fluctuations: Rapid changes in voltage supply, especially during the spin cycle when the motor draws more power, can affect the stability of the electronic components, causing the display to flicker.
Faulty Display Panel: There could be a problem with the display panel itself, such as a loose connection or a malfunctioning component, which is causing the flickering.
Bad Connection: Loose or damaged connections between the display panel and the control board can result in intermittent display issues like flickering.
Electronic Control Board Issues: Problems with the electronic control board that manages the washing machine's functions might affect the display's performance during certain cycles.
Regarding the new brushes being noisy, it's not unusual for carbon brushes in a washing machine's motor to be a bit noisy during the initial few washes. As the brushes wear in and adapt to the motor's commutator, the noise should gradually reduce. However, if the noise persists or becomes excessive, it might indicate improper installation or other motor issues.
To troubleshoot and resolve the flickering display issue and the noisy motor, consider the following steps:
Check Connections: Ensure all connections between the display panel and control board are secure. A loose connection can cause intermittent display issues.
Voltage Stability: Verify that the washing machine is receiving a stable voltage supply. Fluctuations in voltage can impact electronic components. Try using the washing machine on a different power outlet or circuit.
Electromagnetic Interference: Ensure that the washing machine is adequately grounded to minimize electromagnetic interference.
Contact Bosch Support: If the problem persists, it's best to reach out to Bosch customer support or a qualified technician to diagnose and fix the issue. They can perform more in-depth checks and possibly replace any faulty components.
Remember to refer to the washing machine's user manual for any specific troubleshooting steps or contact Bosch customer support for guidance tailored to your model.
