Check the Hose where the sensor is connected, may be loose,
pinched, damaged or clogged. Also check the sensor it may be
disconnected or defective. The Main PCB may also be defective
Check the motor drive connector, it may be loose. The hall sensor
may be disconnected, loose or damaged . Check for a foreign ob-
ject inside the motor or motor damage. The stator might be loose
or damaged. The drum might be overloaded from too many
clothes or the relay or PCB might be defective.
Check the water valve wiring harness.
Check whether the water supply valve is clogged with foreign ma-
terial and whether water is supplied properly.
Check for reversed fill hoses
Check water temperature, if sensed as higher than 50 ˚C in the
Wool or Lingerie cycle it will create error.
Check the relays, if they operate correctly replace the Main PCB.
Correct Hot/Cold hose connections
