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; Filter on inlet valve clogged with foreign material; Inlet valve connectors broken or loose; Inlet valve resistance out of range (should be 0.8-1.2 kΩ); Connector to MAIN PWB disconnected or disassembled (NA2, NA4, BL3); Pressure switch faulty (water level frequency below 24.6 kHz after connector check); Main harness open circuit; Main PWB assembly faulty

How to Fix

1. 1

   Press Soil and Delay Wash buttons simultaneously to check water level frequency

2. 2

   If frequency is below 24.6 kHz: check air chamber and tube for clogging

3. 3

   If frequency is above 24.6 kHz: check inlet valve filter for foreign material — clean or replace filter

4. 4

   Check inlet valve connectors for broken or loose connections — reconnect or repair

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 voltage at inlet valve connector: should be 120V AC while power is on; if 120V present, replace inlet valve assembly

7. 7

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

8. 8

   Verify electrical connection per 9-5 wiring diagram (page 41); if incorrect, replace main harness

9. 9

   After reconnecting connector, recheck water level frequency below 24.6 kHz — if still low, check pressure switch

10. 10

    If all above pass, replace MAIN PWB assembly
