2. Important Safety Information
Always follow basic safety precautions when using electrical appliances to reduce the risk of fire, electric shock, and injury. Read all instructions carefully before operation.
General Safety Warnings:
- Do not touch hot surfaces. Use handles or knobs.
- To protect against electrical shock, do not immerse cord, plugs, or the appliance in water or other liquid.
- Close supervision is necessary when any appliance is used by or near children.
- Unplug from outlet when not in use and before cleaning. Allow to cool before putting on or taking off parts.
- Do not operate any appliance with a damaged cord or plug, or after the appliance malfunctions or has been damaged in any manner.
- The use of accessory attachments not recommended by the appliance manufacturer may cause injuries.
- Do not use outdoors.
- Do not let cord hang over edge of table or counter, or touch hot surfaces.
- Do not place on or near a hot gas or electric burner, or in a heated oven.
- Extreme caution must be used when moving an appliance containing hot oil or other hot liquids.
- Always attach plug to appliance first, then plug cord into the wall outlet. To disconnect, turn any control to “off,” then remove plug from wall outlet.
- Do not use appliance for other than intended use.
- This appliance has a polarized plug (one blade is wider than the other). To reduce the risk of electric shock, this plug will fit in a polarized outlet only one way. If the plug does not fit fully in the outlet, reverse the plug. If it still does not fit, contact a qualified electrician. Do not modify the plug in any way.

5. Maintenance and Cleaning
Regular cleaning and maintenance will ensure the longevity and optimal performance of your Waring Commercial WIH400 Induction Range.
5.1 Daily Cleaning
- Always unplug the unit and allow it to cool completely before cleaning.
- Wipe the ceramic glass surface with a damp cloth and mild detergent. For stubborn stains, use a non-abrasive ceramic cooktop cleaner.
- Wipe the stainless steel housing with a damp cloth. Avoid abrasive cleaners or scouring pads that could scratch the surface.
- Ensure all surfaces are thoroughly dried after cleaning.
5.2 Care for Ceramic Glass Surface
- Avoid dropping heavy objects on the ceramic glass surface, as this can cause cracks or breakage.
- Do not use metal utensils or sharp objects directly on the surface to prevent scratches.
- Clean spills immediately, especially sugary liquids, to prevent them from hardening and becoming difficult to remove.
6. Troubleshooting
If you encounter issues with your induction range, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Unit does not power on. | No power supply; power cord not securely plugged in. | Check power outlet and ensure cord is firmly plugged into both the unit and the wall. |
| No heat generated. | Cookware is not induction-compatible; cookware is too small or too large; pan detection error. | Use induction-compatible cookware. Ensure pan diameter is within 4.7"-10.2". Reposition the pan. |
| Display shows an error code (e.g., E0, E1). | Specific error condition (e.g., overheating, sensor malfunction, pan detection). | Refer to the full user manual for specific error code meanings. Generally, unplug the unit, let it cool, and try again. If the problem persists, contact customer support. |
| Unit makes unusual noise. | Normal fan operation; vibration from cookware. | A cooling fan operates during use; this is normal. Some cookware may vibrate slightly, which is also normal for induction. |
If the problem persists after attempting these solutions, please contact Waring Commercial Customer Support.
