👉 Troubleshooting the Heat Issue

Is your hot tub running but not heating past a certain temperature? Don't worry, this common problem can be fixed with a few simple steps. In this article, we will guide you through troubleshooting the heat issue and replacing the element if needed.

1. Testing the Element

The first thing you want to do is test the element to check if it's functioning properly. Start by opening the side panel to access the spa pack. Locate the element, usually underneath the keypad. Use a digital meter to test the element for voltage. Make sure the meter is set to AC, as the element works on alternating current. If you have trouble getting the meter clamp around the wire, try using a thinner clamp. If the element is not receiving the correct voltage, this could be the cause of the heat issue.

2. Checking for Burnt or Discolored Relays

If the element appears to be working fine, the next step is to check the relays. Open the door of the spa pack and inspect the black relays. Look for any black marks or signs of burning or discoloration. This could indicate a faulty relay that is preventing the heat from reaching the desired temperature. If you find any damaged relays, they will need to be replaced.

👉 Replacing the Element

If testing the element and checking the relays did not resolve the heat issue, it's time to replace the element. Here's how to do it:

1. Removing the Heat Tube

Before removing the heat tube, make sure to drain the hot tub completely. Start by undoing the sensors attached to the heat tube. Then, remove the nuts holding the heat tube in place. Be careful not to twist the wires while removing the heat tube. If necessary, use a smaller meter wrench to hold the element in place while unscrewing it.

2. Installing the New Element

Inspect the new element before installation to ensure it matches the specifications of the old one. Grease the o-rings that came with the element and place them on either side of the heat tube. Carefully slide the new element into the heat tube, making sure it is centered and not touching the sides. Tighten the bolts securely, but avoid over-tightening.

3. Reassembling the Heat Tube

Once the new element is in place, reattach the sensors and nuts to secure the heat tube. Make sure the gaskets are clean and properly seated. Use the appropriate tools to tighten the nuts, being careful not to over-tighten. Check that the heat tube is straight and not twisted to ensure proper water flow.

4. Testing and Adjusting the Element

Before filling the hot tub, turn on the power and check if any air is present in the pump lines. If there is an airlock, open the necessary valves to bleed the air. Once the hot tub is filled, turn on the element and adjust it to the desired temperature. Monitor the element's performance and adjust as needed to achieve the desired heat.

5. Bleeding the Air from Pump One

If you encounter an airlock in pump one, follow these steps to remove the air:

Turn off the power to the hot tub.
Locate the valve for pump one and open it slowly.
Listen for the sound of air escaping and close the valve once the air has been released.
Tighten the valve securely to prevent any further airlocks.

👉 Conclusion

With these troubleshooting steps and the replacement of the element if necessary, you should be able to resolve the heat issue in your hot tub. Remember to follow the instructions carefully and take the necessary precautions while working with electrical components. If you are unsure or uncomfortable with any of the steps, it is always best to consult a professional.

👉 FAQ

Q: How do I test the hot tub element? A: To test the element, you will need a digital meter set to AC. Make sure to follow the manufacturer's instructions for your specific hot tub model.

Q: What should I do if I find burnt or discolored relays? A: If you find burnt or discolored relays, they will need to be replaced. Consult the hot tub manufacturer or a professional for assistance.

Q: Can I replace the element myself, or should I hire a professional? A: If you have experience working with electrical components and feel confident in your abilities, you can replace the element yourself. However, it is always recommended to hire a professional if you are unsure or uncomfortable with the process.

Q: How often should I bleed the air from pump one? A: It is a good idea to check for airlocks and bleed the air from pump one whenever you encounter heating issues or notice a decrease in water flow.
