Product details

The Solaxx Digital Flow Switch FLW-BL-D is the digital flow switch for Solaxx chlorine generators, and it tells the control unit whether water is moving so the cell only runs when there is flow.

Where it is listed

Solaxx's parts catalog lists FLW-BL-D as the Digital Flow Switch and files it under its ComfortChlor, Relaxx and Resilience chlorine generators. Solaxx lists other flow switches too: an Analog Flow Switch with flat connectors, and a Flow Switch with a round connection, GNR00003, filed under Saltron Reliant. The switch types are not interchangeable by description, so go by the part number.

When to replace it

A flow switch that sticks or fails is a common cause of a no flow fault while the pump is clearly running. Rule out a dirty filter, a closed valve and air in the line first. If the fault stays, the switch is the next suspect.

Before you order

Read the part number on your current switch and confirm it is FLW-BL-D, and check that your system is one of the lines above. Solaxx does not publish fit details on the part page, so for an older or unusual unit it is worth checking with Solaxx first.

Questions and answers

What people ask about this product, answered by our pool techs.

What does the flow switch do?
It reports to the control unit whether water is moving through the system. Without flow the unit stops the cell, which protects it from running dry.
How do I know this is the right one?
Compare the part number printed on your existing switch. This is the digital switch, FLW-BL-D; if yours carries a different number, confirm in your system manual before ordering.
My system shows a flow error with the pump running. Is this the fix?
Often, yes. Once you have ruled out a dirty filter, a closed valve or air in the line, a failed flow switch is the usual remaining cause.
Is this a genuine Solaxx part?
Yes, it is the Solaxx part number FLW-BL-D.
