sounds like pump blocked... the two flashing lights are the fault indicator.
u could try......
drain all the water out of the sump(remove the filter arrangement) dry it out and look for a grill at about 2 oclock in the bottom of the sump... get a strong plastic cable tie and insert this into the grill and push it in and out a few times..(the pump impellor is behind the grill).if your're lucky you will dislodge whatever was blocking it and it will start up!mi
