📊 Technical Thresholds, Pinout & Pass/Fail Specifications
| Parameter / Component | Normal / Verified Spec | Fault / Trigger Condition |
|---|---|---|
| Sensor Type | Dual probe optical/resistive moisture contact | Out-of-tolerance reading triggers LC / LE protection state |
| Drain Pump | Locked ON until pan is dry | Inspect wiring harness & replace DD94-01002A if out of spec |
| Clear | Towel dry sensor | Verify continuity and clean terminal connectors before clearing LC / LE |
Understanding the Technical Root Cause
On the Samsung StormWash Dishwasher, this condition occurs when the system's electronic controller detects an out-of-bounds signal on LC / LE. The micro-controller constantly compares live sensor telemetry against factory tolerance thresholds. When readings deviate beyond safety limits, protective lockout routines are activated.
Step-by-Step Diagnostic & DIY Resolution Guide
- Initial Visual & Power Inspection: Disconnect power to the unit. Check all visible wiring harnesses for corrosion, loose terminal pins, or heat discoloration.
- Multimeter Verification: Using a digital multimeter, measure electrical continuity and resistance across the terminals of the Samsung Dishwasher Leak Sensor Assembly (DD94-01002A). Compare your readings to the technical specification table above.
- Service Mode & Recalibration: Follow the service sequence:
Unplug dishwasher, remove lower kickplate, and towel-dry bottom blue sensor tray. This allows direct hardware testing and verification before returning to normal operation.
❓ Frequently Asked Technical Questions (FAQ)
What is the most common cause of this LC / LE issue on Samsung StormWash Dishwasher?
The primary root cause is typically wear or degradation of the Samsung Dishwasher Leak Sensor Assembly, loose electrical wiring harnesses, or sensor calibration drift.
Can I safely use the system while this condition is active?
It is recommended to address this promptly. Continuing to operate under fault conditions can cause secondary damage or lock out operation.
How long does the DIY repair take?
This repair typically requires approximately 25 minutes with basic household hand tools or a digital multimeter.
What is the OEM replacement part number?
The genuine manufacturer part number is DD94-01002A (Samsung Dishwasher Leak Sensor Assembly).
How do I clear the error once the repair is complete?
Follow the procedure: Unplug dishwasher, remove lower kickplate, and towel-dry bottom blue sensor tray. Disconnecting power for 2 minutes also forces a hard capacitor reset.
