Error Code IE

Water Inlet Error

What This Means

Correct water level (24.6 kHz) not reached within 8 minutes after water is supplied; Water level does not reach preset level within 20 minutes; Air chamber or tube clogged; Filter inlet valve clogged with foreign material; Inlet valve connectors broken or loose; Inlet valve resistance out of range (spec: 0.8-1.2 kOhm); Connector at MAIN PWB disconnected (NA2, NA4, BL3); Main harness open circuit; Pressure switch faulty

How to Fix

1. 1

   Confirm IE is displayed on screen

2. 2

   Press WASH/RINSE and DELAY WASH simultaneously to check water level frequency

3. 3

   If water level frequency is below 24.6 kHz: check AIR CHAMBER and tube for clogging

4. 4

   If water level frequency is OK: check if filter inlet valve is clogged — clean or replace filter

5. 5

   Check if inlet valve connectors are broken or loose — reconnect or repair connector

6. 6

   Measure resistance between each terminal of INLET VALVE ASSEMBLY (spec: 0.8-1.2 kOhm) — if out of range, replace INLET VALVE ASSEMBLY

7. 7

   Check voltage at inlet valve connector — should be 120 VDC when energized — if present, replace INLET VALVE ASSEMBLY

8. 8

   Verify connector to MAIN PWB (NA2, NA4, BL3) is connected — reconnect or repair if not

9. 9

   Check electrical connection via wiring diagram — if incorrect, replace MAIN HARNESS

10. 10

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

11. 11

    If all above pass, replace MAIN PWB ASSEMBLY

12. 12

    Installation safety checklist: verify no water tap leakage, no freezing, no hose entanglement or shortage, no hose shrinkage
