Product details

The Raypak 018146F is the water flow switch for Crosswind pool and spa heaters. It is a genuine Raypak product and fits Crosswind models I-30, I-40, I-50, I-65, O-40, O-50 and O-65.

What it does

The flow switch is a safety interlock. It has to see water moving through the heater before the control will let the unit run. That protects the heat exchanger from firing against still water, and it is why a heater with a failed switch simply refuses to start.

Diagnosing it

A no flow message with the pump running points at low flow first: a dirty filter, a partly closed valve, a low water level or a blocked impeller. If the plumbing checks out and flow is good, the switch has failed and a new one puts the heater back in service.

About the Crosswind

The Crosswind is built around inverter technology that adjusts continuously to hold pool temperature, which is what makes it quiet and efficient. That control depends on knowing water is moving, so the flow switch is not an optional part of the system.

Questions and answers

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

Which heaters does this switch fit?
Raypak Crosswind models I-30, I-40, I-50, I-65, O-40, O-50 and O-65.
What does a water flow switch do?
It confirms water is moving through the heater. Until it closes, the heater will not fire, which protects the unit from running dry.
My Crosswind says no flow but the pump is running. Is this the part?
It is the first thing to check, along with a dirty filter, a closed valve or a low water level. If the plumbing is clear and flow is good, the switch itself is the likely fault.
Is this a genuine Raypak part?
Yes. It is Raypak OEM part 018146F.
