Bosch’s US page now marks the NGM8656UC as no longer available. It had five sealed burners across an 800 Series 36 inch top and a hefty 58,500 BTU total. With that much heat rising through the grates, the enamel coating on the cast iron takes the beating as the years go by.
It chips, and where it chips the iron rusts. Grates that look decent are harder to maintain on a hard-working cooktop like this, and they are the part owners most often ask us to replace. The highest-output burner also wears its crown at the ports sooner than the others.
Ventilation comes up too, since a hood chosen for a gentler cooktop will struggle here. On a visit we inspect grates, crowns and caps, test each burner, and look at the hood, then tell you which parts are cosmetic and which actually affect cooking.
Surface rust can be cleaned off, but once enamel keeps flaking the rust returns, and touch-up coatings rarely survive that heat. Replacement grates are the lasting answer, and we can check what is available.
Often yes, particularly when the problems are wearing parts like grates and crowns. We give you a written price and tell you honestly if the cost starts to approach replacement.
It runs hardest and hottest, so its cap and crown take the most punishment. Clean it regularly and replace the crown if the ports start to erode.
