    Low h20 temp @ grouphead

    I have a 2 group C.M.A. SME2N aka Rio aka Astoria. I have noticed the boiler pressure level drops significantly every time I open the steam wand. It holds pressure just fine pulling shots. I then checked the water temp coming from the grouphead by sticking the frothing thermometer into the shotglass as the grouphead dispensed water. It held at a steady 160 Deg F. the hot water dispenser was around 190 F or so. I started investigating further and noticed the main relief valve has a slow steady leak. One last bit of info is the red power indicator light is constantly dimming/flickering. I don't know if any of these things are related.
    Thanks for any feed back.
