If there is gunk in the air dome, use a turkey baster with hot soapy water to try and flush it out. The air dome is welded to the tub and is not removable. If there is no gunk buildup, check the hose for cracks/splits all the way up to the pressure switch behind the control panel. If all is ok, you need to check the pressure switch.
Tried what yousaid but looks like you can take off the silver platet foom behind control panel. see no clips..
