Samsung Washer LE & LE1 Error Repair in Port St. Lucie, FL

Quick symptom overview

Samsung WF, WW, and FlexWash series front-load washers display LE (Water Leakage) or LE1 (Sub-Leakage Sensor Fault) when the main electronic control board (DC92-01621A, DC92-01804A, DC92-01982A) detects standing water or a ground short via Base Pan Leak Sensor Switch DC97-12182A (supersessions DC96-01585A, DC61-02611A, DC97-12182B).

The automatic leak protection system consists of: Main Control Board → cabinet wiring harness → 3-pin connector (Pin 1: +5.0 VDC reference, Pin 2: Signal sense, Pin 3: Neutral GND) → optical/float leak sensor switch DC97-12182A snapped into the galvanized bottom tray → emergency drain pump relay (DC31-00054A). If water leaks from the door bellows gasket, drain pump filter filter housing, or tub seam seal and accumulates in the bottom tray, moisture bridges the sensor contacts, pulling the 5V logic signal to 0V. The main PCB immediately engages the drain pump to prevent home flooding and logs LE / LE1.

LE1 code with standing water under washer: Hose tear, loose drain pump filter cap, or torn door boot gasket (DC64-00563A). LE code with bottom tray bone dry: Moisture / corrosion inside sensor plug DC97-12182A or 5V DC reference supply short on main board.

Safety: Unplug washer 120V AC electrical power cord and turn off hot/cold water supply shut-off valves before removing rear panel or reaching into bottom cabinet tray.

Step-by-step diagnostic hierarchy

1. Inspect bottom tray for standing water and suds (Power OFF — simple check) — Remove lower rear cabinet cover (or front toe kick panel):

   • Check bottom galvanized metal pan for standing water, soap scum foam, or blue detergent trails.
   • If suds/water present: Sponge tray dry thoroughly with towels to clear sensor contacts.
   • Inspect internal components for active leaks: door boot bellows gasket, lower drain pump housing filter seal, tub air breather tube, and water inlet valve triple-solenoid pack.

2. Measure DC reference voltage at Leak Sensor DC97-12182A (Power ON — live check) — Re-plug washer cord into 120V AC outlet and locate sensor snapped into bottom base plate:

   • Back-probe 3-pin harness plug with multimeter set to 20 VDC range:
     • Red (Pin 1) to Black (Pin 3): Expected 4.8 VDC to 5.2 VDC (5.0 VDC nominal).
     • Yellow (Pin 2 Signal) to Black (Pin 3): Expected 4.8 VDC to 5.0 VDC (Dry state); drops to < 0.5 VDC (Wet state).
   • Result: 0 VDC on Pin 1: Trace harness back to main board header CN10. If 5 VDC reference is missing at board header, replace Main Control Board DC92-01621A / DC92-01804A.

3. Measure Leak Sensor switch contact resistance (Power OFF — meter check) — Unplug washer power cord and unclip harness plug from sensor DC97-12182A:

   • Set multimeter to 200k Ω (20,000 Ω) scale:
     • Measure across sensor signal terminals:
     • Dry condition: Expected ∞ Ω (Open circuit / > 100k Ω).
     • Submerge sensor contacts in a small cup of tap water:
     • Wet condition: Expected < 1.0 kΩ (Closed signal path).
   • Result: < 10 kΩ when dry: Corrosion or internal moisture short inside sensor housing → replace Leak Sensor Switch DC97-12182A / DC96-01585A.

4. Verify water tightness during diagnostic test wash (Power ON — leak test) — Re-attach dry leak sensor and initiate a short Quick Wash cycle:

   • Shine flashlight along internal tub seam, drain pump filter housing, and door boot rubber gasket.
   • Tighten loose hose clamps or replace torn door bellows gasket (DC64-00563A) if water droplets appear.

Multimeter and safety checks

Disconnect 120V AC power supply before wiping down bottom base tray or taking resistance measurements on sensor contacts.

Component / Test	Setup & Meter Range	Expected Normal Value	Fault / Failure Mode
DC Vcc Power Signal	Pin 1 to Pin 3 on DC97-12182A, 20 VDC	4.8 VDC–5.2 VDC (5.0 V)	0 VDC (failed DC power supply rail on main PCB)
Leak Sensor Signal (Dry)	Pin 2 to Pin 3, 20 VDC	4.8 VDC–5.0 VDC	< 0.5 VDC (wet base tray or shorted leak switch)
Leak Sensor Resistance (Dry)	Across sensor terminals, 200k Ω	∞ Ω (Open / > 100k Ω)	< 10 kΩ (corroded sensor contacts; logs LE1 dry)
Harness Wire Line	Pin-to-pin sensor to PCB CN10, 200 Ω	< 0.5 Ω per line	∞ Ω (wire broken inside lower cabinet loom)

Root cause vs repair breakdown

Observable Symptom	Root Cause / Faulty Part	Corrective Repair Action
LE / LE1 code, water in tray	Torn door boot gasket or drain pump leak	Replace door boot gasket DC64-00563A or drain pump; dry tray
LE1 code, suds overflowing	Excessive non-HE laundry detergent	Flush tub with warm water cycles; educate on HE detergent use
LE / LE1 code, tray dry, sensor < 10k Ω	Corroded optical/float leak switch	Replace Leak Sensor Switch Assembly DC97-12182A
LE code, 0 VDC at sensor & PCB CN10	Damaged 5V DC reference supply on PCB	Replace Main Control Board Assembly DC92-01621A

FAQ

What does error code LE or LE1 mean on a Samsung front-load washer?

LE / LE1 (Water Leakage Error) indicates that optical/float leak detection sensor DC97-12182A mounted in the bottom cabinet base pan detected standing water or a 5V logic signal drop caused by internal tub, hose, or pump leakage.

How do I test Samsung washer leak sensor switch DC97-12182A with a multimeter?

Unplug washer, turn off water valves, and remove lower front toe panel or rear access cover. Locate leak sensor switch DC97-12182A clipped to bottom sheet metal tray. Unclip 3-pin harness plug. Set multimeter to 20 VDC scale: back-probe Red (5V Vcc) to Black (GND) for 5.0 VDC power. Set meter to 200 Ω scale: measure sensing contacts dry vs wet; expected dry switch resistance is ∞ Ω (Open), dropping to < 10 Ω when water bridges sensing probe pins.

Can oversudsing from excessive HE detergent trigger LE1 error on Samsung washers?

Yes. Excessive foam or non-HE detergent creates thick soap suds that overflow through the rear tub breather vent hose into the bottom cabinet tray, triggering leak sensor DC97-12182A without an actual plumbing hose tear.

Should I replace leak sensor DC97-12182A or main control board DC92-01621A?

If the base pan is completely dry but leak sensor DC97-12182A terminals read < 100 Ω (shorted) or 0 VDC signal feedback, replace Leak Sensor Switch Assembly DC97-12182A / DC96-01585A. If sensor tests dry and normal but 5 VDC reference is missing from main board connector CN10, replace Main Control Board DC92-01621A.
