Indesit Dishwasher: salt light on; not finishing cycle; dirty dishes

Professional Repair Guide

What is this symptom?

If your Indesit dishwasher has the salt light on, isn't finishing its cycle, and your dishes are coming out dirty, you're likely facing a common issue. This can occur even after refilling the dishwasher salt. Possible causes include low or incorrectly filled salt, a malfunctioning salt sensor, or a faulty water inlet valve. Addressing these issues promptly can restore your dishwasher's performance.

Urgency: Medium

Important Tips for Indesit Models

  • Salt light specifically indicates salt level/softener issues; official Indesit guidance recommends salt use for hard water and may indicate calcium deposit issues if cloudy dishes appear.

How to Identify: Salt light indicator on the control panel is lit/flashing; visible low salt level in salt compartment; cloudy/spotty dishes from hard water

Part: Salt reservoir/softener unit

Salt sensor/float malfunction or dirt blocking the sensor

How to Identify: Salt light stays on after correct salt refill; sensor area may have buildup or debris

Part: Salt level sensor/float switch
