Bosch dishwasher is about 9 years old and I installed a new control module (PN 488428) and now I am unable to disable the end of cycle alarm. When I hold down the two cancel buttons and then the on/off button I get a red light on one of the buttons but I never hear a beep. If I let go of the buttons it looks like I am in service mode as pushing buttons will toggle some red lights but I never hear a beep. I have tried different settings like going into service mode and then toggle to the first setting and trying it and I still get an end of cycle alarm beep and then going in again and trying the second setting and I still get an end of cycle beep. I'm guessing since I never hear a beep that I'm not in the correct mode to disable the alarm.

Are there new/different instruction to disable the alarm with new/replacement control modules? I can take it apart and remove the beeper from the control board but I am getting really tired of taking this unit apart.

The new control did not come with anything other than the part. The dishwasher seems to go through its cycles fine. Is there a way to tell if programming is required?
