E28
The E28 error code on Bosch washing machines indicates a fault with the flow sensor. This sensor monitors the water flow entering the machine and plays a crucial role in various wash cycles.
Possible Causes of E28 error:
- Faulty flow sensor:
- The sensor itself might be malfunctioning due to electrical issues, internal damage, or mineral buildup.
- Blocked water inlet:
- Debris like dirt, scale, or even small objects can clog 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 E28 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 E28 error.
Important Note:
Due to the potential for electrical components and delicate parts involved, it's strongly recommended to avoid any DIY troubleshooting for the E28 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 E28 error code and your model number. They can provide expert advice based on your specific machine and offer solutions like:
- Guiding you on simple checks like inspecting the water inlet hose for visible blockages.
- Scheduling a qualified technician visit for safe diagnosis and repair of complex issues like faulty sensors or control board problems.
- Do not attempt to reset the machine: While resets help with some errors, it's not recommended for E28 as it might not resolve the underlying issue and could potentially worsen it.
Additional Tips:
- Having your model number readily available when contacting customer service will expedite the process.
- If you suspect a leak due to potential 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.
