Error Code IE

Water Inlet Error

What This Means

Water level frequency below 24.6 kHz (air chamber or tube clogged); Filter inlet valve clogged with foreign material; Inlet valve connectors broken or loose; Inlet valve assembly resistance out of range (should be 0.8-1.2 kOhm); Inlet valve connector at MAIN PWB disconnected (NA2, NA4, BL3); Electrical connection issue — replace main harness; Pressure switch defective; MAIN PWB assembly defective; No water tap supply, frozen tap, kinked or leaking supply hose

How to Fix

1. 1

   Confirm IE is displayed.

2. 2

   Press Soil + Delay Wash simultaneously to check water level frequency. If below 24.6 kHz, check air chamber and tube for clog.

3. 3

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

4. 4

   Check inlet valve connectors for damage or looseness — reconnect or repair.

5. 5

   Measure resistance between each terminal of inlet valve assembly: should be 0.8-1.2 kOhm. If out of range, replace Inlet Valve Assembly.

6. 6

   Check voltage at inlet valve connector — should be 120 VAC while power is on. If yes, replace Inlet Valve Assembly.

7. 7

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

8. 8

   Verify electrical connection is correct per wiring diagram (page 41). If not, replace Main Harness.

9. 9

   After reconnecting connector, recheck water level frequency. If still below 24.6 kHz, check Pressure Switch.

10. 10

    If all above pass, replace MAIN PWB Assembly.

11. 11

    Installation check: no water tap leakage, no freezing, no hose entanglement, no water shortage, no hose shrinkage, no hose leakage.
