2. Safety Instructions
Please read these safety instructions carefully before using your WMF Function 4 Advanced Casserole to ensure safe operation and prolong the life of your product.
- Heat Safety: While the handles are designed to stay cool on the stovetop, always use oven mitts or pot holders when handling the casserole, especially after oven use or prolonged cooking.
- Oven Use: The casserole itself is oven safe up to 250°C. When using the glass lid, the maximum oven temperature is 180°C. Exceeding these temperatures may damage the lid or casserole.
- Glass Lid Care: Avoid sudden temperature changes with the glass lid (e.g., placing a hot lid under cold water) as this may cause it to crack. Do not use if the lid is chipped or cracked.
- Hot Liquids: Exercise extreme caution when draining hot liquids using the lid's pouring functions. Ensure the lid is securely positioned to prevent spills and burns.
- Children: Keep the casserole out of reach of children, especially when hot or in use.
- Induction Cooktops: Ensure the casserole is centered on the induction hob for efficient and even heating.
3. Setup
- Unpacking: Carefully remove the casserole and all its components from the packaging. Retain packaging for future storage or transport if needed.
- Initial Cleaning: Before first use, wash the casserole and lid thoroughly with warm soapy water. Rinse well and dry completely to remove any manufacturing residues.
- Inspection: Inspect the casserole and lid for any signs of damage. Do not use if damaged.
4. Operating Instructions
4.1 Stovetop Compatibility
The WMF Function 4 Advanced Casserole is equipped with a TransTherm universal base, making it suitable for all common stovetops:
- Induction Cooktops
- Gas Cooktops
- Electric Cooktops
- Ceramic Cooktops
For optimal performance, ensure the casserole's base diameter matches or is slightly smaller than your stovetop burner.
4.2 Using the Multi-functional Glass Lid
The innovative glass lid allows for four distinct positions, providing versatility for cooking and draining:

- Closed Position: Align the solid part of the stainless steel ring with the pouring rim for a tight seal, ideal for simmering and retaining heat.
- Large Sieve Holes: Rotate the lid to align the large holes with the pouring rim. This position is perfect for draining larger ingredients like pasta or potatoes.
- Small Sieve Holes: Rotate the lid to align the small holes with the pouring rim. Use this for draining smaller ingredients such as rice or vegetables.
- Open Position: Align the open section of the lid with the pouring rim for easy pouring of liquids without straining, or for allowing steam to escape.
4.3 Using the Internal Measuring Scale
The casserole features a practical internal measuring scale, allowing you to accurately measure liquids directly inside the pot, reducing the need for additional measuring tools.
4.4 Oven Use
The casserole is suitable for oven use up to 250°C without the lid, and up to 180°C with the glass lid. Always use oven mitts when removing the casserole from the oven.
5. Maintenance and Care
Proper care will ensure the longevity and performance of your WMF Function 4 Advanced Casserole.
- Cleaning: The casserole and glass lid are dishwasher safe. For best results and to maintain the polished finish, hand washing with warm soapy water and a soft sponge is recommended.
- Stubborn Stains: For stubborn food residues, soak the pot in warm soapy water before cleaning. Avoid abrasive cleaners, steel wool, or harsh scouring pads, as these can scratch the stainless steel surface.
- Water Stains: To prevent water spots, especially in areas with hard water, dry the casserole immediately after washing. For existing water spots, a solution of vinegar and water can be used, followed by rinsing and drying.
- Storage: Store the casserole in a dry place. If stacking, place a cloth or paper towel between pots to prevent scratches.
6. Troubleshooting
Here are some common issues and their potential solutions:
- Food Sticking: Ensure you are using adequate cooking oil or liquid. For stainless steel, preheating the pot before adding food can help prevent sticking. Avoid cooking at excessively high temperatures.
- Discoloration: High heat or certain foods (e.g., highly acidic foods) can sometimes cause slight discoloration on stainless steel. This is usually harmless and can often be removed with a stainless steel cleaner or a paste of baking soda and water.
- Uneven Heating: While the TransTherm base is designed for even heating, ensure the casserole is properly centered on the heat source. On gas stoves, adjust flame size so it does not extend beyond the base of the pot.
- Lid Not Sealing Properly: Check for any food debris or residue on the rim of the pot or lid that might prevent a proper seal. Ensure the lid is correctly aligned.
