Electric Cooktops

Cleaning & Care

General Cleaning
What cleaners should I avoid when cleaning my electric cooktop? Do not use the following cleaners:

  • Cleaners that contain ammonia or chlorine bleach
  • Caustic cleaners (such as Easy Off®)
  • Abrasive cleaners
  • Dishwashing agents
  • Metal scouring pads
  • Scrub sponges
  • Soap-filled scouring pads
  • Flammable cleaners
These products can damage, scratch, and dull your cooktop.
How to clean a glass cooktop. Apply a small amount of glass cooktop cleaner to a soft, clean cloth. Wipe this on the cooled cooktop and then buff with a clean, dry towel.

Visit the How-To Videos page and watch the "How to Clean Glass Cooktops" video to learn more.

Warning: Do not use any cleaners on the glass while the surface is hot. The resulting fumes may be hazardous to your health and result in death or injury. A glass scraper may be used to scrape stuck-on food debris off the cooktop while the surface is hot.
How to remove stuck-on food debris from the cooktop. Use a glass scraper to remove stuck-on food debris from the cooktop.

Here's how to remove dried sugar, sugar syrup, milk, tomato spills, melted plastic film, and foil with a glass scraper. These types of debris can be removed while the cooktop is still hot:

  • 1. Turn off the cooktop and remove any cooking pans and utensils.
  • 2. Wearing an oven mitt, hold the scraper at a shallow angle (20 to 30°), being careful to not gouge or scratch the glass. Push the loosened soil off the heated area with the scraper.
  • 3. After the cooktop surface has completely cooled, remove the loosened soil and apply a glass cooktop cleaner.


Here's how to remove burnt-on debris with a glass scraper:

  • 1. After the cooktop has cooled, lay a damp paper towel or sponge on top of the debris for 30 minutes.
  • 2. Carefully remove the debris with the scraper. Use the scraper at a shallow angle (20 to 30°) with smooth strokes and avoid stabbing or chipping the surface.
  • 3. Remove the soil and apply a glass cooktop cleaner.

How to clean stainless steel surfaces. Clean stainless steel areas by using mild soapy water with a soft cloth. Wipe in the direction of the stainless steel grain when washing and drying. Rinse with water and wipe dry to avoid watermarks. Do not use cleaners that are abrasive or contain chlorine since both are corrosive to stainless steel. For added shine, apply a stainless steel conditioner and wipe off the excess with a soft cloth.

Visit the How-To Videos page and watch the "Cleaning Stainless Steel Appliances" video to learn more.
Warning: Stainless steel conditioners and cleaners can have negative effects on materials other than stainless steel. Do not apply stainless steel conditioners and cleaners to control markings, labels, logos, black or smudge-proof stainless steel, and appliance interiors.
Stains & Scratches
How to remove hard water stains. Minerals in some water can be transferred onto the cooktop surface and cause stains. Apply undiluted white vinegar with a soft, clean cloth. Then, recondition with a glass cooktop cleaner.
How to remove scratches, fractures, or cracks on the glass. Scratches - Unfortunately, scratches cannot be removed but your cooktop will continue to operate correctly. To help prevent scratches in the future, keep your cooktop and pan bases clean and dry and make sure your pots and pans do not have any rough or damaged areas.

Fractures and cracks - If your cooktop is fractured or cracked, it is no longer usable and you must switch off the fuse to prevent the risk of electric shock. We cannot accept warranty claims for scratches or fractures on the cooktop.

Usage & Operation

Power & Malfunction
The cooktop does not turn on. There are several solutions for this problem:

  • The cooktop may not be plugged in. Check to see if it is plugged in.
  • The main switch is turned off. Make sure to turn the unit on.
  • Check to see if you are experiencing a power failure.
  • The power may not be flowing to the socket. Check if there is electricity in the outlet in question by using another small object that runs on electricity (e.g., hair dryer). If there is no electricity in the outlet, consult an electrician.
  • The fuse may have blown or the circuit breaker tripped. Replace the fuse or reset the circuit breaker.
The domestic fuse has tripped. Check whether the residual-current-operated circuit-breaker (FI) or the domestic fuse for the electric circuit has tripped. The main fuse and residual-current-operated circuit-breaker (FI) are for your safety and respond if there has been an overload or short-circuit in the electric circuit. Check whether other appliances in the electric circuit caused an overload. If required, contact an electrician.
The cooktop is connected to the wrong main connection. Switch off the fuse in the fuse box and have the appliance connected correctly by an electrician.
The cooktop seems to be on even though it is turned off. The HOT indicator light is on because the surface is still hot. This light is on for safety reasons.
Heating Elements
The heating elements are not fully red and certain sections are darker. This is normal for your cooktop and it is operating correctly. The heating element consists of several elements that will glow during operation. There are no heating elements where the electrical connection and the cable duct are routed. The glow pattern remains dark at these points.
The heating elements show different levels of brightness. Differences in brightness are due to technical reasons and are normal. The heating elements are operating correctly.
Other
How to activate and deactivate the child lock. Activating child lock - The cooktop must be turned off. Then, touch LOCK for 4 seconds. An indicator will light up for several seconds. The cooktop is now locked.

Deactivating child lock - Touch LOCK for 4 seconds. The cooktop is now unlocked.
Why does it take longer to cook on an electric glass cooktop than on an electric coil cooktop? With electric coil cooktops, the cookware is placed in direct contact with the heating elements. For glass cooktops, the heating elements are beneath the glass. Consequently, heat must pass through the glass before it comes in contact with the cookware.

What types of cookware are suitable for my electric cooktop? You can use stainless steel, glass, or aluminum pots and pans. Copper and ceramic pots and pans may scratch the cooktop. Make sure the cookware has a flat base, a base diameter that matches the diameter of the heating element, and can conduct heat well.
