6. Maintenance and Cleaning
Regular cleaning and maintenance will ensure the longevity and optimal performance of your microwave oven.
6.1 Exterior Cleaning
Wipe the exterior surfaces with a soft, damp cloth. Do not use abrasive cleaners or harsh chemicals.
6.2 Interior Cleaning
Clean the oven interior after each use. For stubborn food splatters, place a bowl of water with lemon slices inside and heat for a few minutes on high power. The steam will loosen the residue, making it easier to wipe clean with a damp cloth.
6.3 Turntable and Grill Rack
The glass turntable and metal grill rack can be removed for cleaning. Wash them in warm, soapy water or in a dishwasher. Ensure they are completely dry before placing them back in the oven.
7. Troubleshooting
If you encounter issues with your microwave oven, refer to the following common problems and solutions:
- Oven not starting: Check if the power cord is securely plugged in. Ensure the door is fully closed. Check your household fuse/circuit breaker.
- Food not heating: Ensure the correct power level and cooking time are set. Check that the door is properly latched.
- Sparking inside the oven: Remove any metal utensils or foil from the oven. Ensure containers are microwave-safe.
- Turntable not rotating: Ensure the turntable is correctly placed on its support ring and the central hub. Check for any obstructions.
If the problem persists after checking these points, contact Electrolux customer service for assistance.
