Error Code IE

Water Inlet Error

What This Means

Correct water level (24.6 kHz) not reached within 8 minutes after water is supplied; Preset water level not reached within 20 minutes; Air chamber or tube clogged; Inlet valve filter clogged with foreign material; Inlet valve connectors broken or loose; Inlet valve resistance out of range (should be 0.8-1.2 kΩ); Connector disconnected from MAIN PWB assembly (NA2, NA4, BL3); Electrical connection faulty (refer to wiring diagram); Pressure switch defective

How to Fix

1. 1

   Confirm IE is displayed on panel

2. 2

   Press WASH/RINSE and DELAY WASH simultaneously to check water level frequency — if below 24.6 kHz, check air chamber and tube for clogging

3. 3

   If frequency is OK, check if inlet valve filter is clogged — if yes, clean or replace the filter

4. 4

   Check inlet valve connectors for looseness or breakage — if broken, reconnect or repair the connector

5. 5

   Measure resistance between each terminal of inlet valve assembly: should be 0.8-1.2 kΩ — if out of range, replace INLET VALVE ASSEMBLY

6. 6

   Check if inlet valve connector is at 120V AC while power is on — if yes, replace INLET VALVE ASSEMBLY

7. 7

   Check connector at MAIN PWB assembly (NA2, NA4, BL3) for disconnection — if disconnected, reconnect or repair

8. 8

   Check electrical connection per wiring diagram (page 53) — if faulty, replace MAIN HARNESS

9. 9

   After reconnecting connector, re-check water level frequency — if still below 24.6 kHz, check PRESSURE SWITCH

10. 10

    If all above checks pass but error persists, replace MAIN PWB ASSEMBLY

11. 11

    Installation safety check: verify no water tap leakage, no freeze, no hose entanglement, no water shortage, no hose shrinkage, no hose leakage
