Bosch Oven E044, Touch Control Module Refused the Option Code

What E044 means

A touch control module sits behind the glass panel. Every time the oven powers up, the main control module attempts to load an option code into it, and E044 reports that the load failed. The manual lists a failing touch module or poor wiring to it as the reasons, and says the logged error stays until a reset is done.

Common causes of E044

Link between the control module and the touch module loose or damaged
Touch module that refuses to take the option code
Option code entered wrongly after an earlier board swap

✓ One safe check you can try

1. Turn the oven off at the breaker and give it two minutes, since a reset has to happen before this error will go away. 2. Restore power and watch the start-up. 3. If E044 appears again right away, the write is genuinely failing and not a one-time glitch. 4. Leave the panel alone.

! Why to stop there

The touch module and its connections are behind the glass panel, close to live wiring.
A wrong option code, a bad connection and a bad module all produce this code.
Re-seating connectors without the right tools can bend pins and damage the module.

Opening a panel yourself does not automatically cancel a manufacturer warranty, but it can cause accidental damage, and some manufacturers set their own service conditions. Check your warranty terms, or ask us, before deciding.

E044E044 questions

What is an option code?

It is a stored value that tells the board which oven it is part of. If the write fails, the touch module cannot be set up correctly.

Did a past repair cause this?

Possibly. If a board was replaced earlier and the option code was never set properly, E044 can show up at the next start-up, sometimes weeks after the original repair.

What is the usual repair?

We check the connections, test the touch module and set the option code if needed. You see a written price first, and our work carries a 30-day workmanship warranty.
