E20
The E20 error code on Bosch washing machines signifies unexpected heating during a non-heating cycle, such as the rinse cycle. This suggests the water is heating when it shouldn't be, potentially harming your clothes or causing damage to the machine.
Possible Causes of E20 error code:
- Faulty Heating Element:
- The element responsible for heating the water might be malfunctioning, activating even during unneeded cycles.
- Temperature Sensor (NTC) Issue:
- This sensor measures water temperature and sends data to the control board. A malfunctioning sensor could send incorrect readings, leading the machine to believe heating is necessary even when it's not, triggering the E20 error.
- Control Board Error:
- In rare cases, the control board managing the washing process might malfunction and misinterpret sensor signals, causing unexpected heating and the E20 error.
- Software Glitch:
- While less likely, a temporary software glitch within the control board could lead to unexpected heating cycles.
Important Note:
Do not attempt any DIY troubleshooting for the E20 error due to the potential for electrical hazards and damage. Incorrect handling could worsen the issue, create electrical dangers, or even lead to water leaks.
Recommended Action:
- Contact Bosch Customer Service Immediately: Inform them of the E20 error code and your model number. They can provide expert advice based on your specific machine and offer solutions like:
- Scheduling a qualified technician visit for safe diagnosis and repair.
- Guiding you on potential safety measures based on the severity of the issue (e.g., unplugging the machine if necessary).
- Do Not Reset the Machine: Resetting might not resolve the underlying issue and could 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:
- Have your model number ready when contacting customer service for faster assistance.
- If you suspect a leak due to unexpected heating, turn off the water supply 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.
