No worries! Here’s an easy step-by-step guide for replacing your spa pack heating element. In this guide, we’ll be working with a Balboa spa pack that has an M7 heating unit located at the bottom.

Removing the Heating Element

Removing the heating element is a straightforward process that can be completed in just three simple steps.

Step 1: Disconnect the Power Cables

Begin by removing the power cables from the heating element. To do this, unscrew the top of the power unit, then carefully disconnect the two power connectors.

Step 2: Remove the Temperature Sensor

Next, use a wrench to loosen and remove the temperature sensor from its housing.

Step 3: Extract the Heating Element

Finally, reach in from the side and pull out the heating element. In the example video above, we’re using a brand new element, but if you’re looking for a replacement for your hot tub, you can check out our selection here.

Reinstalling the Heating Element

Now that the old element is out, let’s reinstall the new one using the same three steps in reverse order.

Step 1: Insert the Heating Element

First, carefully insert the new heating element, making sure to align it with the mounting holes. This can be a bit tricky, so take your time. Once aligned, prop it up slightly and secure it in place with washers and bolts.

Step 2: Reinstall the Temperature Sensor

Next, drop the temperature probe back into its housing and tighten the bolt around it to secure the connection.

Step 3: Reattach the Power Cables

Finally, reconnect the power cables by placing them in their respective positions and bolting them down.

And that’s it! You’ve successfully replaced your hot tub spa pack heating element.
