Inlet Error — machine does not reach normal water level within fill timeout

What This Means

Water supply tap is closed; Wiring connection to inlet valve or hall sensor disconnected; Inlet hose kinked; Water pressure too low (below 10 psi) or too high (above 120 psi); Inlet valve filter clogged with dirty water; Inlet valve faulty (resistance out of range 23-27 ohm); Air breaker impeller stuck; Hall sensor faulty (resistance should be 9 kΩ ±5%); Controller (main PCB) damaged

How to Fix

1. 1

   Open the water supply tap

2. 2

   Check and reconnect wiring at connectors NA8 and WH4 (water supplied, frequency not increasing path) or WH6 (water not supplied path)

3. 3

   Check if hall sensor resistance is 9 kΩ ±5%; replace if not

4. 4

   Check voltage between WH4 pin4 and NA8 pin1: should be 5V DC ±15%; replace main PCB if out of range

5. 5

   Check if inlet valve filter is clogged; close tap, unscrew inlet hose, clean filter

6. 6

   Check voltage between WH6 pin5-6: should be 8V DC ±15%; replace main PCB if out of range

7. 7

   Check inlet valve resistance: should be 23-27 ohm; replace valve if not

8. 8

   Replace air breaker if impeller not spinning

9. 9

   Replace main PCB assembly if all above checks pass

10. 10

    LQC Mode check: Press Power+Start, then Start 5 times to listen for water supply sound, then Power to turn off
