Bosch Dishwasher: burning smell
What is this symptom?
If you notice a burning smell coming from your Bosch dishwasher during operation, it may indicate overheating components or damaged wiring. This persistent odor, especially during heating phases, should not be ignored, as it could signify serious electrical issues that require immediate attention.
Important Tips for Bosch Models
