The water wasn't being heated up properly on this hot tub. The steps to diagnose and find the cause are shown in this video. Fortunately in this case it was the electrical connection right on the heater (inside the heater box) that had corroded, so a clean up and new wiring meant it was fixed. It would be the same steps if replacing the heater element tube with a new one.
This tub is old but similar steps would apply to other tubs / spas.
The crimping tool set with spade connectors can be had here:

And if you want to use the shrink wrap see these sets:

Amazon USA: amzn.to/2okx3ix
A cheap multimeter for measuring ac voltages and resistance:

Of course be careful with electricity. Disconnect the hot tub from the electricity supply before dismantling. It is your responsibility that you are comfortable and qualified to do this work.
