FL14177 Fleck 5600 Manual Regen knob

The FL14177 manual regeneration knob is the genuine control fitted to Fleck 5600 water softener and filter valves, allowing you to manually start a regeneration cycle by turning the timer on. WrekinWater stocks this replacement knob for customers whose existing knob has worn, cracked or stopped engaging the valve's internal timer.

Technical specifications

Symptoms that mean you need this part

• The knob spins freely without turning the internal timer cam
• The knob is visibly cracked, chipped or has broken off completely
• You can no longer manually trigger a regeneration cycle when needed
• The knob slips rather than engaging when you try to turn it

Why it fails / why it matters

The manual regen knob engages directly with the toothed shaft of the valve's timer cam, letting you force a regeneration on demand. Repeated hand pressure over years of use gradually wears down the internal teeth or splits the plastic shaft, so the knob starts to slip or spin without turning the timer at all, leaving you unable to trigger a manual regeneration.
