Six burners on one cooktop lead to a common misunderstanding, and the HGS8655UC is a good example. This 800 Series gas range is 36 inches wide, with 94,000 BTU spread over six sealed burners, a 3.4 cu ft oven and a circulating fan. A few of those burners are smaller by design.
The dedicated simmer burner draws the most complaints because owners expect all six to bring water to a boil at the same pace. Output for each burner is published, so before we call anything broken, we compare it with the specification. A slow burner that matches its rating is working correctly.
Beyond the burners, two other things come up over time. Spill residue collects where the grate arrangement meets the top, and the oven’s convection fan may begin to whine as its bearing wears. We check the specification and the fan during the visit.
Bosch mixes burner outputs on purpose, with smaller ones for gentle cooking. Check each one against the published ratings first, since a blockage is less likely.
A noisy fan is generally a worn bearing. The repair is contained, and it is worth doing early, since a seized fan ends convection cooking.
Wait until the range is cool, lift them off and wash them separately from the top. That keeps residue from baking on around the burners, where it can collect under the grate arrangement across all six.
