Frigidaire / Ikea Dishwasher i20 & i30 Error: Pressure Sensor Kit (#5304504077)
Quick Answer: The i20 (Drain Timeout) and i30 (AquaControl Flood Sensor) error codes on a Frigidaire, Electrolux, or Ikea dishwasher are overwhelmingly caused by a grease-fouled Pressure Sensor Switch. Frigidaire released an updated Anti-Foam Pressure Sensor Calibration Kit (#5304504077) to permanently fix false i20 and i30 errors.
⚠️ Why Your Pump Is Fine on Frigidaire i20: Even when the dishwasher is 100% empty of water, a faulty Pressure Switch (#5304504077) stays stuck in the 'Full' state. The dishwasher runs the drain pump dry for 3 minutes and throws i20!
