12012598 Genuine Rapid Burner Cap, Matt Black, for Bosch, Siemens, Neff Gas Cooktops, BSH Large Burner Cover Replacement

Genuine BSH part 12012598 is a matt black cap for the rapid burner, the larger, high output burner on a European style gas cooktop. It suits Bosch, Siemens and Neff cooktops built with this cap. Rapid caps are bigger than the semi-rapid and auxiliary caps on the same cooktop, so they can't be swapped between positions. Check your parts list for 12012598, or compare it with your old cap, before ordering.

Rapid burner flame uneven or slow to light?

On the rapid burner, the cap rests on the burner crown and spreads the gas into a wide, even ring of flame for fast boiling and searing. A cap that has cracked, warped from heat or lost patches of its matt black coating can cause lazy yellow flames, flames that lift off the ports, uneven heat under the pan and a burner that clicks for a while before it catches. A damaged cap also lets boil-overs run down into the burner, which blocks ports and makes the problem worse.

Changing the rapid burner cap

Turn every burner off and let the cooktop cool. Take off the trivet over the rapid burner, lift the old cap away and brush spill residue out of the crown ports. Seat the new cap squarely so it doesn't rock. Light the burner and look for an even blue flame around the whole cap. A smell of gas, a leak or damaged burner parts need a licensed gas fitter.

Questions about this part

Will this cap fit my semi-rapid or small burner?

No. 12012598 is the cap for the rapid burner, and the semi-rapid and auxiliary burners take smaller caps with their own numbers. Check the burner position on your cooktop's parts list, or measure the old cap, before ordering.
