Part 12012910 is the genuine small size, the ported ring that carries gas up under the cap and spreads it into the flame. It belongs to Bosch, Siemens and Neff gas cooktops that use this number. The smallest burner on a cooktop is often the auxiliary, used for simmering, but the burner position isn't on our record, so compare sizes before ordering.\u003c\/p\u003e\n\u003ch2\u003eSmall burner flame patchy or hard to light?\u003c\/h2\u003e\n\u003cp\u003eA small burner tends to be the one used for simmering sauces and keeping food warm, so it spends long periods on a low flame. That makes an even gas spread especially important. When the diffuser warps, cracks or clogs with burnt-on spills, the low flame can flicker, go out, burn on one side only or refuse to catch from the spark. You might also see the flame lifting off the ports, or a yellow, sooty flame. A new diffuser restores the correct port pattern so the flame sits close and steady.\u003c\/p\u003e\n\u003ch2\u003ePart details\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eGenuine BSH part 12012910\u003c\/li\u003e\n\u003cli\u003eSmall size burner diffuser\u003c\/li\u003e\n\u003cli\u003eSpreads the gas flow evenly under the cap\u003c\/li\u003e\n\u003cli\u003eFor BSH gas cooktops that list this number\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ctable class=\"part-specs\"\u003e\u003ctbody\u003e\u003ctr\u003e\n\u003cth\u003eSize\u003c\/th\u003e\n\u003ctd\u003eSmall\u003c\/td\u003e\n\u003c\/tr\u003e\u003c\/tbody\u003e\u003c\/table\u003e\n\u003ch2\u003eReplacing a small burner diffuser\u003c\/h2\u003e\n\u003cp\u003eTurn off the cooktop and wait for it to cool fully. Take off the cap and pull the old diffuser straight up. Wipe the burner base clean and dry, and check the spark electrode isn't cracked. Line the new diffuser up with its locating notch, seat it flat, then put the cap back on top. Test on a low setting. If the flame still won't stay alight, ask a licensed gas fitter to check the flame failure device.\u003c\/p\u003e\n\u003ch2\u003eQuestions about this part\u003c\/h2\u003e\n\u003ch3\u003eHow do I check this is the right size?\u003c\/h3\u003e\u003cp\u003eMeasure across the old diffuser and compare it with your cooktop's parts list, which shows the diffuser number for each burner.
