Bosch Range Error Code E044

E044 indicates a Touch Control Module option code error. During startup, the main control module attempts to set a configuration code on the TCM board in the front panel. If this process fails due to bad connections or a faulty TCM, the E044 fault is logged. The range cannot operate normally until the option code is successfully set.

E044 is a control communication fault that typically prevents normal startup of the range. Because the touch interface may not function reliably, attempting to operate the appliance in this state is not recommended. The burners or oven may not respond predictably, creating a potential safety concern.

If the issue is resolved by setting the option code in Service mode or reseating a wiring connection, the cost is primarily labor, which typically ranges from around 80 to 150 dollars depending on your area. If the front panel assembly containing the TCM board requires replacement, parts and labor combined could range from 200 to 500 dollars or more, depending on the specific range model and part availability.

A technician comfortable with appliance electronics can attempt to resolve E044 by entering Service mode and setting the correct option code, then inspecting all wiring harness connections between the control module and the front panel. If the connections are secure and the option code still cannot be set, the front panel assembly will need to be replaced, which is a more involved repair. Homeowners without experience accessing appliance service modes or working with wiring harnesses should consider calling a qualified technician.

A simple power reset is unlikely to permanently clear E044 because the fault is caused by a structural issue, either a bad connection or a failed TCM board, that the control module will detect again on the next startup cycle. The correct fix involves entering Service mode to set the option code or replacing the front panel assembly if connections are confirmed to be good.
