Lay-Z-Spa Pre 2021 HydroJet PTC Heater – Genuine Replacement Heating Element

Is your Lay-Z-Spa HydroJet not heating properly, displaying E02 errors, or tripping your electrics? This genuine Lay-Z-Spa Pre 2021 HydroJet PTC heater is designed to replace faulty internal heating elements and restore full heating performance to older style HydroJet spa pumps.

This version uses the same PTC heater block as standard Lay-Z-Spa models but features longer cables designed specifically for older Pre-2021 HydroJet heater units.

What Is the Lay-Z-Spa PTC Heater?

The PTC (Positive Temperature Coefficient) heater is the internal metal heating element responsible for heating the spa water. When faulty, your spa may stop heating completely, intermittently trip the RCD, or display E02 flow and heating-related errors.

Common signs of a faulty PTC heater include:

• Water not heating correctly
• E02 error codes
• RCD or electrics tripping when heat activates
• Intermittent heating faults
• Heater failing without visible error codes

This genuine replacement heater is designed to restore safe and reliable heating performance.

Important Compatibility Information

This heater is only suitable for Lay-Z-Spa systems using metal PTC heater blocks.

✅ Compatibility check:
Your existing heater should be a metal heater block and not the newer black plastic style.

This version is specifically designed for older Pre-2021 HydroJet spa pumps and uses extended cables for easier installation.

If unsure, simply contact us with a photo of your spa unit before ordering.

Water Chemistry Warning – Protect Your Heater

PTC heater blocks are made from metal and can become damaged by incorrect water chemistry over time.

Low pH, excessive copper levels, poor alkalinity balance and aggressive spa water can all cause pitting corrosion inside the heater block. This can eventually lead to:

• Internal leaks
• Reduced heating efficiency
• Heater failure
• E02 errors
• Electrical tripping

Pitted or corroded heater blocks should always be replaced.

⚠️ Please note:
Corrosion caused by poor water chemistry is not covered under warranty.

We strongly recommend regularly testing spa water and using LayZRepair No Scale to help protect your heater core, seals and internal pipework from limescale and corrosion build-up.
