⭐ What’s Included in This Lay Z Spa Refurbishment Kit

✔ New PTC Heater Core

Restores correct heating and improves water movement through the heater block.

✔ 2 × Red Silicone Heater Seals

These high-temperature, chemical-resistant seals provide long-lasting leak protection.

✔ Water Flow Paddle & Pin

A worn paddle can cause E02 faults. Replacing it often restores correct flow detection.

✔ Silicone Water Flow Switch Seal

This seal prevents internal leaks and helps ensure accurate sensor operation.

✔ Nitrile Impeller Shaft Bushings

Worn bushes lead to wobbling impellers, reduced flow, vibration and grinding noises. New bushings solve this immediately.

Designed to withstand heat and chemicals, this seal protects the main pump chamber.

✔ Water Pump O-Ring

Provides a reliable seal around the pump body to maintain correct internal pressure.
