What makes WDT740SALZ stand out.

  • AI Intelligent Wash
  • Tall Top Rack
  • Sensor Cycle

The Whirlpool WDT740SALZ is a current top-control dishwasher. It adds a tall top rack and a sensor-driven AI Intelligent Wash at a 47 dBA sound level.

The codes we see most are F6E1 (low water fill), F8E1 (slow fill), F9E1 (will not drain), F3E1 (thermistor), and F7E1 (wash motor). We clear the filter and drain path and test the inlet valve before fitting a genuine OEM part. See dishwasher repair and our dishwasher error-code guides.
