Quick answer

Frigidaire dishwasher code Tu: what a flashing turbidity sensor failure display means.

Model compatibility: Frigidaire has used more than one control platform, so Tu may mean something different on another appliance or generation. Confirm this against your model documentation and record your full model number before acting.

Plain language

What this code means

Tu is the flashing display code for a detected turbidity sensor failure.

What Tu stands for

Tu is tied to the turbidity sensor. The display flashes it once a failure of that sensor is detected.
