I think that you spread the outer part of the panel with a small screw driver to get the faceplate off.....trying to remember. Maybe others will answer with more certainty.
Does your water pump work ?? Again, if memory serves me correctly, there is only 1 hot wire to the unit, and if the water pump relay doesn't work, that is a good indication that there is no juice going to the panel.
