Bosch HGI8056UC 800 Series 30 in Gas Slide-In Range E020 Error Fix: Gas Igniter Failure — Bake

Error code E020 on the Bosch HGI8056UC 800 Series 30 in Gas Slide-In Range means: Gas Igniter Failure — Bake. The gas igniter for the bake burner (bottom of oven) is not glowing or is not reaching sufficient temperature to open the gas safety valve. Bosch gas ovens use a hot-surface (glow-bar) igniter — when it reaches approximately 1,800°F, it draws enough current to open the gas valve. If the igniter glows but the gas does not ignite, the igniter may be weak (drawing insufficient amperage). Measure igniter current — it should draw 3.2-3.6 amps. Replace the igniter if current is below specification. Check the gas safety valve if the igniter tests good.
