1. Check your pressure switch. Should be on the bottom of board but connected to your heating element tube. Unplug the red and green wires and buy pass with a wire. ( running a wire from one terminal to the other. Do with with all power off, and if still nothing, try with everything running.  )

If you still have the three blinking dots on the control pannel and a light on the upper right side of the C-Board. Then you will need to replace the board ($300)..  But if you get heat after bypassing the pressure switch, then you know its just the Pressure switch. ( $25 )   

If you need to replace the pressure switch, make sure you shut off all the water tubes,  and release water pressure from the heating element by loosing the the heating element to let some water out of the tube. You do not want any water to get on the c-board
