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

A Samsung dishwasher in Alliance developed flashing error lights that stopped normal washing cycles. The Heavy and Smart Auto lights were blinking during operation, indicating a water level sensor issue. We found debris blocking the case brake water level sensor assembly.

The Problem

The customer reported that their Samsung DW7933LRASR/AA dishwasher was displaying flashing Heavy and Smart Auto lights during wash cycles. The unit would start but couldn’t complete normal operations due to these error codes. The flashing pattern typically indicates water level sensing problems in this model series.

Diagnosis

Testing revealed an obstruction in the case brake water level sensor assembly. This sensor monitors water levels in the dishwasher tub and triggers error codes when it can’t get accurate readings. Debris had accumulated in both the sensor assembly and the connecting hose leading to the sump, preventing proper water level detection. When the sensor can’t determine if the dishwasher has enough water or if it’s draining properly, it triggers the flashing error lights as a safety measure.

The Repair

• Parts replaced: None required
• Work performed: Cleared obstruction from case brake water level sensor assembly and cleaned connecting hose to sump
• Result: Error lights cleared, normal wash cycles restored, sensor readings verified accurate

Is It Worth Repairing?

This Samsung DW7933LRASR/AA is a solid mid-range dishwasher that typically runs 8-12 years with proper maintenance. Since this repair involved only cleaning existing components rather than replacing expensive parts, it’s definitely worth fixing. The underlying dishwasher mechanics are sound, and clearing sensor obstructions is routine maintenance that extends the appliance’s life.

Maintenance Tips for Samsung Dishwashers

• Clean the case brake sensor area monthly by running an empty cycle with dishwasher cleaner to prevent debris buildup
• Check and clean the bottom filter regularly — Samsung dishwashers rely on clean filters for proper water circulation and sensor function
• Use rinse aid consistently, especially in Stark County’s hard water areas, to prevent mineral deposits in sensor assemblies
