Can a bad dispenser assembly cause the nf code to appear only before rinse cycle?I have replaced both of the inlet valves and the problem is the same those were the pats suggested for the nf code apearing
A dispenser issue would not cause the NF error code. You will want to check the following for this error:
Check the water valve wiring harness.
Check whether the water supply valve is clogged with foreign material
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.
