Operating Instructions
Cooking on Stovetops:
- Heat Management: The TransTherm universal base provides excellent heat distribution. Start with medium heat and adjust as needed. High heat is rarely required and can lead to scorching or food sticking.
- Induction Compatibility: These pots are fully compatible with induction cooktops. Ensure the pot is centered on the induction zone.
- Lid Usage: The heat-resistant glass lids allow you to monitor cooking without lifting, helping to retain heat and moisture.
- Pouring: The wide pouring rim is designed to facilitate drip-free pouring of liquids.

Oven Use:
The WMF Diadem Plus pots are oven safe. However, always check the maximum temperature rating for the glass lids if using them in the oven. Generally, stainless steel pots without non-stick coatings are safe for high oven temperatures.

Care and Maintenance
- Cleaning: The WMF Diadem Plus pot set is dishwasher safe. For hand washing, use warm water, a mild dish soap, and a soft sponge or cloth. Avoid abrasive cleaners or steel wool, which can scratch the surface.
- Stubborn Food Residue: For stuck-on food, fill the pot with water and a small amount of dish soap, bring to a simmer, and let it soak for a while before cleaning.
- Water Spots/Discoloration: Stainless steel can sometimes develop water spots or slight discoloration due to mineral content in water or high heat. These can often be removed with a solution of vinegar or lemon juice, followed by a thorough rinse and dry.
- Drying: Always dry your pots and lids thoroughly after washing to prevent water spots and maintain their shine.
- Storage: Store pots and lids in a dry place. To prevent scratches, place a cloth or paper towel between stacked pots.

Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Food sticking to the bottom | Too high heat; insufficient oil/fat; food added to a cold pan. | Preheat the pot properly on medium heat. Use a sufficient amount of cooking fat. Avoid overcrowding the pot. |
| White spots or mineral deposits | Hard water residue; starch from food. | Clean with a solution of vinegar or lemon juice. Rinse thoroughly and dry immediately. |
| Rainbow discoloration (heat tint) | Overheating the empty pot; high heat cooking. | This is harmless and common with stainless steel. It can often be removed with a stainless steel cleaner or a vinegar solution. Prevent by avoiding extreme high heat on an empty pot. |
| Handles getting hot | Prolonged cooking on high heat; oven use. | Always use oven mitts or pot holders when handling hot pots, especially after prolonged cooking or oven use. |
