Dang

It's not too long.

trying one more time...

Length looks fine but the drain line needs to be looped up higher than the connection to the disposal. It's called a "high loop." Check the user guide and installation instructions for your Bosch, but every Bosch I've ever owned or installed has required that the drain line have either a high loop or an air gap (which effectively accomplishes the same thing.) For example, illustrations and requirements were on pages 27 and 28 of the installation instructions for the Bosch 300 I installed last year for a friend as well as the one I installed for myself the previous year.

If the installer did not leave you with the installation instructions that came with your dishwasher, you can download a pdf copy of the one for your model from Bosch or from vendor web sites.

If "high loop" and "air gap" are unfamiliar terms, you might find this article and its illustrations helpful.

This is easily fixed. You can do a high loop yourself with very little effort. If your town's codes require an air gap --- some do, some do not, and some do not require them for Bosch DWs as explained in this [this recent thread here on air gaps [(https://www.houzz.com/discussions/bosch-dishwashers-dont-need-air-gaps-dsvw-vd~5413794)--- and your sink/counter is not already set-up for one, installing an air gap can be a simple DIY project if you have the tools. Otherwise, you might need a plumber.

Thank you, I knew it wasn’t right, but didn’t know what was wrong.. installers made multiple errors... seems they got nothing right...
