Frigidaire Dishwasher Error Code i30

On dishwashers without a display, the “END” LED flashes (2 Hz / 5 sec pause) – 3 blinks

A leakage occurred, the water piled up in the pan at the bottom of the hull, the Aquastop float surfaced and closed the contacts.

Possible causes

There is only one reason in this case i30 errors; it is the leak tightness of one of the system elements. This may be a crack in the tank, and a leakage in the junctions of the nozzles and hoses. Careful inspection of the entire dishwasher system is required.


  • check the tightness of the storage tank;
  • check the condition of the hoses and connections;
  • Check tightness of seals and cuffs.
