What to do if the non-water switch doesn't work on my Samsung DW80M2020US?

If the non-water switch isn't working during the pre-wash phase of your Samsung Dishwasher, it could be due to several reasons. First, check if the water supply pressure is low and ensure the water supply valve is open. If these are fine, the non-water switch itself might be broken and need replacing. Also, the wash pump might not be working, or there could be issues with the Main PBA. Inspect or replace the Main PBA.
