Bosch NEM73UC Cooktop
Frequently Asked Questions (16)
What should I do before using the cooktop for the very first time?
Remove all packing materials and literature from the cooktop surface, then wipe with a clean damp sponge and dry while cool. Apply the Cooktop Cleaning Creme® packaged with the cooktop and buff with a clean cloth. There may be a slight odor during the first several uses, which is normal and will disappear. (Page 5)
Why does my heating element keep cycling on and off even at the highest setting?
This is normal behavior — the temperature limiter operates automatically to protect the glass ceramic surface from extreme high temperature damage. If the element cycles more than usual, possible causes include a warped pan base not making full contact with the heating surface, a pan that is too small for the element, boiled-dry ingredients, or a pan material that transfers heat too slowly. (Page 12)
How do I activate the dual element on my cooktop?
To turn on both the inner and outer elements together, push down on the control knob and turn it clockwise past the number 9 setting to the dual element marker. The dual ON indicator light will glow, confirming that the dual element is on. Then turn the knob counterclockwise to your desired heat setting. To turn off the dual element, turn the knob to the OFF position. (Page 6)
How long does the cooktop surface stay hot after the elements are turned off?
The cooking surface will hold heat and remain hot for up to 25 or 30 minutes after the elements have been turned off. The hot surface indicator light will remain on until the cooking area has cooled to a safe-to-touch temperature. Use caution when working or cleaning around the cooktop while the hot surface indicator light is still on. (Pages 5, 7)
What should I do if sugar, syrup, milk, or plastic spills onto the hot cooktop surface?
These spills require immediate removal — failure to do so can permanently damage the surface. While the surface is still hot, use the razor blade scraper held at a 30-degree angle to push the soil off the heated area, wearing an oven mitt for protection. After the surface cools, remove any residue and apply the Cooktop Cleaning Creme®. (Page 11)

What is the warranty coverage for the Bosch NEM73UC cooktop?
The standard limited warranty covers defects in materials and workmanship for 12 months from the date of installation, with BSH repairing or replacing the unit at no charge. An extended limited warranty then covers the electric heating elements, controls, and ceramic glass from month 12 through month 60 from the date of installation, excluding labor and shipping costs. These warranties apply only to the original purchaser and are not transferable. (Pages 13–14)
How do I clean the control knobs, and can I soak them?
Pull the knob up to remove it — slip a towel under the knob, hold the edges of the towel together, and use the towel for leverage to pull up. Wipe the knob with a hot, soapy cloth, then rinse and dry. Do not soak the control knobs. (Page 10)
What should I do to prepare the cooktop before using it for the very first time?
Remove all packing materials and literature from the cooktop surface, then wipe it with a clean, damp sponge and dry it while cool. Next, apply the Cooktop Cleaning Creme® packaged with the cooktop and buff with a clean cloth. There may be a slight odor during the first several uses, which is normal and will disappear. Read all safety precautions and Use and Care Manual information prior to operating. (Page 5)
Why does my cooktop element keep cycling on and off even on the highest setting?
This is normal behavior — the temperature limiter operates automatically to protect the glass ceramic surface from extreme high temperature damage. Each radiant heating element has its own sensor that will cycle the element off regardless of the cook setting. If the element cycles more than usual, it may be due to a warped pan base, a pan too small for the element, boiled-dry contents, or a pan material that transfers heat too slowly. (Page 10)
What cleaners should I avoid using on the glass ceramic cooktop surface?
Avoid glass cleaners containing ammonia or chlorine bleach, as these ingredients may permanently etch or stain the cooktop. Caustic oven cleaners such as Easy Off®, abrasive cleaners, metal scouring pads like Scotch Brite®, soap-filled scouring pads like SOS®, powdery cleaners with chlorine bleach, and flammable cleaners like lighter fluid or WD-40 should also be avoided. Using any of these can cause permanent damage or scratching to the surface. (Page 8)
How long does the cooktop surface stay hot after turning off the elements?
The cooking surface will hold heat and remain hot for up to 25 to 30 minutes after the elements have been turned off. A hot surface indicator light on each element will automatically illuminate to warn you when the surface is still too hot to touch. The light remains on until the cooking area has cooled to a safe-to-touch temperature. (Page 5)
What should I do immediately if sugar, syrup, milk, or plastic spills on the hot cooktop?
These spills require immediate removal — failure to do so can permanently damage the cooktop surface. While the surface is still hot, use the razor blade scraper held at a 30-degree angle to push the soil off the heated area, being careful not to gouge or scratch the glass. Remove the pan and turn off the element first, and wear an oven mitt for protection. After the surface cools, remove any residue and apply the Cooktop Cleaning Creme®. (Page 9)
What type of cookware works best on this cooktop?
Flat, medium-to-heavy-weight pans with smooth metal bottoms work best, as the pan base should rest evenly on the surface without wobbling when hot. The base of the pan should cover or match the diameter of the element being used, and may overhang the element area by up to 1 inch (25.4 mm) all around. Avoid pans with rounded, concave, convex, warped, or dented bottoms, and do not use glass pans as they may scratch the surface. (Pages 5–6)
The cooktop controls will not turn on — what should I check?
First, check the power source to see if a fuse has blown or if the circuit breaker has tripped. Also check the power supply to ensure the cooktop is receiving electricity. These are the suggested troubleshooting steps listed in the manual before calling for service. (Page 10)
What is the warranty coverage for the NEM73UC cooktop?
The standard limited warranty covers defects in materials and workmanship for 12 months from the Date of Installation, during which BSH will repair or replace the cooktop at no charge under normal use conditions. An extended limited warranty covers the electric heating elements, controls, and ceramic glass from month 12 through month 60 from the Date of Installation, with parts replacement at no charge but excluding labor, transportation, and shipping costs. The warranty applies only to the first using purchaser and is not transferable. (Pages 11, 13)
How do I clean and care for the cooktop on a daily basis?
Apply a small amount of Cooktop Cleaning Creme® before each use using a clean cloth to remove dust or metal marks and provide a protective film. After cooking, wipe off spatters with a clean, damp sponge or paper towel, rinse, and dry, using white vinegar if smudges remain. Always clean the surface when it is completely cool, except for sugar, syrup, tomato products, and milk spills, which must be removed immediately with the razor blade scraper. Buff with Cooktop Cleaning Creme® after cleaning to recondition the surface. (Pages 7–8)
