can I get a user manual for my new slimline dishwasher model SRV43MO3GB?

You can get Manuals online from Bosch Home Appliances Website, Although the model you have given is not listed. They are all pretty much the same, find one like yours and see if it helps or maybe you did a typo in the question.
Here is a link to the dishwasher page.

Copy and paste that into the address bar.
