That bolt is for the pressure switch on AUTO level HWH systems. NOT used and is just a PLUG. I have NEVER seen a Jack (HWH) NOT fully extend for any type defect.

What happens when all 4 HWH Jacks extend?

If all 4 jacks extend (including the one that did not extend before), then either that jack solenoid is bad or there is NO 12 volt power to THAT solenoid when power is applied. When doing this test, all jacks will extend as long as the pump is running, when the pump syops all 4 jacks will then retract 4.
