We have replaced the control board and the pressure switch on our washer. We have determined the switch is not being triggered due to lack of pressure in the hose. The hose is not clogged. It does look like there is some "sludge" in the bottom of the air dome. when the washer is filling, the water does not fill the air dome. When you remove the tube, the water fills the dome, but when the tube is replaced, the water will not continue to fill. Is there a way to clean the dome? Or to create pressure in the hose?

I cannot find the model number of the machine itself anywhere. I used the model number of the parts themselves to replace them.

Thanks so much for the help!
