Samsung Dishwasher Repair (Model DW7933LRASR/AA) – Alliance, OH

A Samsung dishwasher in Alliance, OH was showing flashing Heavy and Smart Auto lights and wouldn’t start any wash cycles. We found an obstruction in the water level sensor assembly that was causing erratic readings and preventing normal operation.

The Problem

The customer reported that their Samsung DW7933LRASR/AA dishwasher had Heavy and Smart Auto indicator lights flashing on the control panel. The unit would fill and drain properly, but no wash cycles would run. The flashing lights indicated the control board was detecting inconsistent water level readings from the sensor assembly.

Diagnosis

Testing revealed the fill and drain functions worked normally, but the water level sensor was giving erratic readings. We found debris blocking the case brake water level sensor chamber and partially obstructing the hose connection to the sump. This blockage prevented the sensor from accurately detecting water levels, triggering the error condition and cycle lockout.

The Repair

• Parts replaced: None required
• Work performed: Cleared case brake chamber and hose to sump of debris
• Result: Normal fills and cycles with no error lights

Is It Worth Repairing?

This Samsung model is a solid mid-range dishwasher, and clearing a sensor blockage is a minor repair that extends its useful life significantly. The DW7933LRASR series typically runs 10-12 years with proper maintenance, making this repair worthwhile for most units under 8 years old.

Maintenance Tips for Samsung Dishwashers

• Check and clean the case brake area monthly — Samsung’s sensor design is sensitive to debris accumulation
• Clean the fine mesh filter at the bottom of the tub every 2-3 weeks to prevent particles from reaching sensor areas
• Run empty hot cycles with Samsung dishwasher cleaner quarterly to clear mineral buildup in sensor chambers
