Hayward Pool AquaRite Error Code 13: How to Fix It

Q: Can I run my pool pump with error code 13?

The pump will still run, but the chlorinator will stop producing chlorine. You can run the pump temporarily, but fix the flow issue as soon as possible to avoid algae growth.

Q: How do I reset Hayward AquaRite error code 13?

The error clears automatically once proper flow is restored. If it doesn't, turn off the pump, wait 30 seconds, and turn it back on. If the error returns, there is still a flow problem.

Q: Will a dirty salt cell cause error code 13?

Yes, a heavily scaled cell can restrict water flow, triggering the no-flow error. Regular cleaning every 3-6 months can prevent this.

Q: Can I bypass the flow switch?

No, bypassing the flow switch is dangerous and can damage the cell or control board. Always repair or replace the switch.

Q: What is the part number for a Hayward AquaRite flow switch?

The OEM part is Hayward GLX-FLO-POOL. Generic equivalents are also available and work well.

Abstract

Error code 13 on your Hayward AquaRite salt chlorine generator indicates a 'no flow' condition, meaning the flow switch detects insufficient water flow through the cell. This can be caused by a clogged filter, closed valves, a bad flow switch, or a dirty cell. Ignoring this error can lead to chlorine production stopping and potential damage to the system.
