Hi
Problem is water keeps filling tub at high setting ok at low or medium
It possible could be the switch

question
the pressure switch hose where it conects to the tub has something in it that looks like it could be a clog or some kind of filter. In your picture of the part it shows a clear hose with no obstructions of any kind. Could this be the problem, that it's some debris that got into the line from the tub.
Thank you

Yes a blockage would be a problem. There should be nothing but air. The increased air pressure as it fill closes the switch. Take the tube off and clear it.
