Product Description
The Fleck 26776 is the genuine 230V/50Hz, 1/15rpm replacement motor for Fleck 5600 series control valves, supplying the mechanical drive that steps the piston through each stage of a regeneration cycle. WrekinWater stocks this exact motor for customers whose 5600 valve has stopped indexing, stalled during a cycle, or is producing an unusual grinding or humming noise without the piston actually moving.

Symptoms that mean you need this part

- A steady hum or buzz from the valve with no visible piston movement
- The cycle indicator gets stuck partway through a regeneration
- The softener suddenly starts producing hard water with no other apparent fault
Why it fails / why it matters
This slower 1/15rpm motor is used on Fleck 5600 valves that need a more gradual cycle progression, and like all valve motors it runs through thousands of regeneration cycles over its working life. Internal gear wear, winding degradation and moisture exposure near the valve body are the most common causes of failure. Once the motor can no longer generate enough torque to turn the piston through the valve body, the electronic timer can continue operating normally while the mechanical cycle simply never happens, leaving the resin bed unregenerated and hardness passing straight through to your taps.
Why buy this from WrekinWater
WrekinWater has served more than 50,000 customers over 15 years from our base in Bettisfield, Shropshire, and we stock genuine Pentair Fleck motors alongside Autotrol, Clack and Kinetico parts, so you get the correct speed and voltage match for your 5600 valve rather than guessing at compatibility. As a family run company rated "Excellent" on Trustpilot, we're happy to help confirm this is the right motor for your softener before you order.
How to fit it
- Isolate the electrical supply to the softener before starting any work.
- Turn off the water supply and switch the valve to bypass if fitted.
- Locate the motor on the front of the valve body and identify its retaining screws.
- Disconnect the electrical connector and remove the old motor from its mounting.
- Fit the new 26776 motor, reconnect the electrical connector, and secure it in place.
- Restore power and water, then trigger a manual regeneration to confirm the valve cycles correctly.
