Bosch Localized Overheating of Housing

Plastic housing around the top or rear feels deformed or discolored from heat.

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Blocked exhaust vents, Misaligned heater shield, Fan not providing adequate airflow, Prolonged operation at maximum temperature

Safety first: Unplug and allow to cool. Do not continue using if plastic is melting or charring.

Steps:

1. Clear vents: Ensure all vents are unobstructed and clean.
2. Inspect heater shield: Open the housing and verify the metal heat shield around the heater is correctly positioned and not missing.
3. Fan function: Confirm the fan is running strongly; replace if weak.
4. Replace damaged parts: Replace any deformed plastic covers and re‑evaluate airflow after repair.
