fdl 570?

i have 4 lights flashing, the salt, rinse aid, Pause/Start, and the dryer light. The cold water empties then refills then the pump starts and thats when you get the fault code. Ive taken the pump apart and cleaned it out it did show some signs of wear near the propeller and I have a slight leak from the bottom of it but not enough to trigger the flood switch. My gut instinct is telling me that the heat isn't working because I noticed the water was cold when it first emptied. I dont have any salt or rinse aid in the machine at present.
