Troubleshooting a Hot Tub That Won't Heat Up
Is your hot tub not heating up properly? Do you find that the temperature does not rise above a certain level, even though the heat is on? If so, there could be a problem with the element. In this article, we will guide you through the troubleshooting and replacement process to get your hot tub back up and running in no time.
Testing the Element
Before diving into the more complicated steps, it's essential to check if the element is functioning correctly. Most likely, the element is located underneath the keypad area of your hot tub. To test the element, you will need a volt meter set to DC mode. Carefully measure the voltage to ensure it is within the expected range. If the reading falls outside of the normal range, it's time to replace the element.
Checking for Burnt Relays
If the element appears to be in good condition, the next step is to check for burnt or discolored relays. Open the door of your hot tub and inspect the black relays. Look for any visible signs of burning or discoloration, as this could indicate a faulty relay. Replacing the relays may solve the heating issue in some cases.
Draining the Hot Tub
Before proceeding with any repairs, you will need to drain the hot tub completely. Unfortunately, if your hot tub lacks shut-off valves, you will need to empty the entire tub. Prepare for this step by ensuring you have a drain or suitable outlet nearby. Once emptied, you can move on to the next steps.
Removing the Heat Tube
To access and replace the element, you will need to remove the heat tube. Begin by removing any sensors connected to the heat tube. Unscrew these sensors carefully to avoid damage. Depending on the tub's design, some additional screws may secure the heat tube. Take note of the position and arrangement of these screws for easy reassembly later. Once all screws are removed, you can gently pull out the heat tube.
Replacing the Element
Now that the heat tube is removed, you can proceed with replacing the element. Start by inspecting the old element and noting its specifications. Order a new element with the same wattage and offset positioning as the original. Apply a thin layer of grease to the new element's o-rings to ensure a proper seal. Carefully insert the element into the heat tube, making sure it is centered and not touching any sides. Secure the element using the provided bolts, being careful not to tighten too much.
Reassembling the Hot Tub
With the new element in place, it's time to reassemble the hot tub. Begin by reinstalling the heat tube, ensuring the gaskets are properly aligned. Carefully tighten the screws to secure the heat tube in place. Reconnect any sensors that were previously removed, ensuring a proper fit. Double-check that all connections are secure before moving on to the next steps.
Bleeding Air from the System
After reassembling the hot tub, it's crucial to bleed any air from the system. Airlocks can disrupt the water flow and prevent proper heating. Open the air release valve and wait for any air to escape. Once you hear a steady flow of water, close the valve. Check for any leaks around the connections and tighten them if necessary.
Testing the Element Again
With the hot tub reassembled and air removed from the system, it's time to test the element again. Fill the tub with water, ensuring the water level covers the jets and skimmer. Set the desired temperature and turn on the hot tub. Monitor the temperature as the hot tub heats up. If the temperature rises to the desired level, congratulations! Your hot tub is now functioning properly.
Conclusion
Troubleshooting and repairing a hot tub that won't heat up can be a challenging task. By following the steps outlined in this article, you can diagnose issues with the element, replace it if necessary, and get your hot tub back to optimal temperature. Remember to take safety precautions and seek professional assistance if needed. Enjoy your rejuvenating hot tub experience once again!
