Your Lay-Z-Spa offers the perfect way to unwind, but to keep it running smoothly and efficiently, regular maintenance—especially of the heater—is essential. The heater is one of the most critical components of your hot tub, responsible for maintaining the water temperature and overall spa experience. Without proper care, it can become less efficient, or worse, stop working altogether. Below are the best practices for maintaining your lay z spa heater to ensure longevity, performance, and safety.
1. Clean the Filter Regularly
Although the filter is not part of the heater itself, it plays a crucial role in heater performance. A clogged or dirty filter restricts water flow, which can cause the heater to overwork or shut down due to low circulation.
Tip: Clean your filter every 2–3 days and replace it every 2–4 weeks, depending on usage. Always turn off the spa before cleaning or changing the filter.
2. Check for Limescale Buildup
If you live in an area with hard water, limescale can accumulate in the heater over time, reducing its efficiency and potentially damaging internal components.
Tip: Use a descaler or water softener regularly to prevent scale build-up. You can also buy Lay-Z-Spa’s official Antiscale Pack to help manage mineral deposits.
3. Monitor and Maintain Proper Water Levels
The heater relies on consistent water flow to function correctly. If the water level is too low, the pump won’t circulate properly, which can cause the heater to shut off or trigger error codes like E02.
Tip: Ensure the water level is always between the minimum and maximum lines marked inside the tub.
4. Use the Timer and Power Saving Modes
Overworking your heater by constantly running it at high temperatures can lead to faster wear. Most modern Lay-Z-Spa models come with timer functions and power-saving settings.
Tip: Use the timer to schedule heating only when needed, especially during long gaps between uses. This saves energy and reduces unnecessary strain on the heater.
5. Keep the Heater Unit Dry and Covered
While Lay-Z-Spa units are built for outdoor use, moisture can still affect the control panel and electrical components over time.
Tip: Always use the provided cover when the spa is not in use. Make sure the heater unit is placed on a level, dry surface, and never allow water to pool around the base.
6. Avoid Running the Heater in Freezing Conditions
Running the heater in freezing temperatures without proper insulation can damage the unit.
Tip: Use an insulating ground mat and a well-fitted cover during cold weather, or drain and store the spa if you don’t plan to use it in winter.
7. Inspect for Error Codes
If you notice an error code like E03 or E04, address it immediately. Ignoring heater-related error messages can result in more serious issues.
Tip: Refer to your user manual or Lay-Z-Spa’s website for guidance on specific codes and how to resolve them.
Routine maintenance of your Lay-Z-Spa heater doesn’t require much time but can make a big difference in performance and longevity. With clean filters, proper water levels, scale prevention, and smart usage, your spa will remain warm, efficient, and ready for relaxation whenever you need it.
