The fix

Water inlet valve

No water detected / long fill

$30-60 easy difficulty 30 min Tools: screwdriver, nut driver, pliers

Diagnose first: Check water supply valves are fully open and inlet screens aren't clogged with sediment BEFORE replacing the valve. Low water pressure also triggers this.

How to fix it

  1. Turn both hot and cold supply valves fully open.
  2. Unplug the washer, disconnect both fill hoses at the back, and inspect the screens — clean or replace if clogged.
  3. Reconnect hoses, run a quick wash, and watch the fill rate.
  4. Test each solenoid coil on the inlet valve for continuity (typically 500-1500Ω).
  5. Replace the water inlet valve assembly if a coil is open or the valve doesn't open electrically.
  6. If still failing, verify household water pressure with a gauge.

Why it happens

Typical signs: Washer adds water very slowly or not at all · Display shows F8 E1, LF, or Lo FL after about 8-10 minutes · Hot or cold side noticeably weaker than the other tap · Inlet screens visible debris when removed

  • Water supply faucets not fully open The single most common cause — partial open faucet behind the washer.
  • Clogged inlet screens Mineral/scale debris in the small screens at the back inlet ports of the washer.
  • Kinked or pinched fill hose Hose bent behind the unit.
  • Failed water inlet valve Solenoid coil open or valve mechanically stuck closed.
  • Low household water pressure Pressure under 20 psi will trip this code.
