How to clean the Pressure Switch Hose

I was told by a repairman that the source of my washer’s problems is most likely coming from a clogged Pressure Switch Hose. I need instructions showing me how to safely get to it without damaging the washer. Thank you

Open the console and locate the component that has a 1/4" hose attached to it. As long as you don’t see any water in the tub, remove the hose from the switch and blow into it. If it’s clear, you’ll hear the air, and maybe some gurgling as you blow. If you don’t hear anything, there is some kind of blockage. Post what you get.
