Kitchen remodels in mid-size homes land on the HBL8451UC more often than on almost any other Bosch single wall oven. It is a 30″ unit, and owners usually treat it as a quiet workhorse until the day the door will not unlatch.
With age, the part that tends to speak up first is the door lock. Self-clean puts the most strain on that mechanism, so a lock that has been wearing for months can show itself right after a cleaning cycle, especially if the oven has not been self-cleaned for a long stretch. Sensors and the control board are the other two areas that show up in service records for this oven.
When we arrive, we start with the error code on the display. An E028 sends us to the latch, E027 or E118 sends us to the temperature sensor, and E029 sends us to the board, particularly if the household recently had a power surge.
No, it is a normal feature. The caution is that a tired door lock tends to give out during or after the cycle, so a lock that has been acting up is worth having checked before you start one.
Not usually. Temperature complaints on this model most often come from one failing sensor, not from the way the oven is designed, and replacing that sensor typically restores normal results.
It can. A surge is the usual reason behind an E029 board error on this model, which is why we ask about recent electrical events when we take the call.
