Share This Guide

There’s nothing quite like enjoying a swim in a heated pool, but what happens when your pool heater suddenly stops working? One common issue that Raypak pool heater owners may encounter is the SPK code. This code can be alarming initially, but with the proper knowledge and troubleshooting steps, you can quickly get your pool heater back up and running. In this article, we’ll dive into what the SPK code is, why it appears, and what you can do to fix it.

What is the Raypak Pool Heater SPK Code?

The SPK code on your Raypak pool heater refers to a safety feature designed to shut off the heater in case of a problem. SPK stands for “safety pilot kit,” which is a component that helps regulate gas flow to the burner. If the safety pilot kit detects an issue, such as a gas leak or low pressure, it will trigger the SPK code and shut down the heater.

Why is the SPK Code Appearing on My Raypak Pool Heater?

There are several reasons why the SPK code may appear on your Raypak pool heater. Some common causes include:

  • Obstructions in the burner tray, such as dirt, debris, or spider webs
  • Low gas pressure or a gas leak
  • A faulty igniter or flame sensor
  • Wiring or control board issues

How to Troubleshoot the SPK Code on Your Raypak Pool Heater

If you’re seeing the SPK code on your Raypak pool heater, there are a few steps you can take to troubleshoot the issue.

  • Check for Obstructions in the Burner Tray

One common cause of the SPK code is a clogged or obstructed burner tray. Check the tray for any debris, dirt, or spider webs that may prevent proper gas flow. If you find any obstructions, clean them out and try rerunning the heater.

  • Check the Gas Supply

Low gas pressure or a gas leak can also trigger the SPK code. Check the gas supply to make sure there are no leaks or blockages. You may also need to adjust the gas pressure if it’s too low.

  • Check the Igniter and Flame Sensor

The issue may be with the igniter or flame sensor if the burner tray and gas supply are clear. Check the wiring and connections to ensure everything is secure and properly connected. You can also try cleaning the flame sensor with a soft brush or sandpaper to remove buildup.

How to Resolve the SPK Code on Your Raypak Pool Heater

If none of the troubleshooting steps above resolve the SPK code on your Raypak pool heater, it may be time to replace the igniter or flame sensor. These components can wear out over time and may need to be replaced to restore the proper functioning of the heater.

If you’re uncomfortable performing the replacement yourself, or if you’re still experiencing issues after replacing the components, it’s best to call a professional to diagnose and repair the problem.

  4. Disconnect the wiring from the igniter.
  5. Install the new igniter and connect the wiring.
