F28
The F28 error code on Bosch washing machines indicates a fault with the flow sensor. This sensor is responsible for monitoring the water flow entering the machine during various wash cycles. Depending on your specific model, the F28 code might represent a slightly different issue related to water flow.
Possible Causes of F28 error:
- Faulty flow sensor:
- The sensor itself might be malfunctioning, sending inaccurate or no signals to the control board.
- Blocked water inlet hose or filter:
- Debris like sediment, scale, or even small objects can get trapped in the inlet hose or filter, restricting water flow and triggering the error.
- Low water pressure:
- Insufficient water pressure from your home's plumbing can lead to inconsistent flow, confusing the sensor and causing the F28 error.
- Wiring problems:
- Damaged or loose wiring connected to the flow sensor can disrupt communication with the control board, leading to erroneous readings and the error code.
- Control board error:
- Less commonly, a malfunction within the control board could misinterpret signals from the flow sensor, resulting in the F28 error.
Important Note:
Due to the potential involvement of electrical components and delicate parts, it's strongly recommended to avoid any DIY troubleshooting for the F28 error. Incorrect handling could damage the machine, create electrical hazards, or even lead to water leaks.
Recommended Action:
- Contact Bosch customer service immediately: Inform them of the F28 error code and your model number. They have expert knowledge and can:
- Provide specific advice based on your machine and assess the severity of the issue.
- Offer solutions like scheduling a qualified technician visit for safe diagnosis and repair.
- Guide you on basic checks if deemed safe, such as inspecting the water inlet hose for visible blockages.
- Do not attempt to reset the machine: While resets help with some errors, it's not recommended for F28 as it might not resolve the underlying issue and could potentially worsen it.
- Unplug the machine: As a safety precaution, unplug the machine from the power outlet until a qualified technician can assess the issue.
Additional Tips:
- Having your model number readily available when contacting customer service will expedite the process.
- If you suspect a potential leak due to flow sensor issues, turn off the water supply to the machine as an extra precaution. However, prioritize contacting Bosch customer service first for expert guidance.
- Remember, safety is paramount. Leave the diagnosis and repair to qualified professionals to ensure your Bosch washing machine is fixed correctly and operates safely again.
