Hi,
We have a Wailea Coast Spa probably about 10 years old (bought second hand from an individual). Runs on 240V. We have had the spa up and running for about 6 months and today one of the wires melted on the circuit board whilst the heater and pump #1 was running.
I have posted some photos on the following link.

It looks to me that box P20Heater and P21High Limit #1 have been swapped places on the board as compared with the diagram.
Questions
1. Can we replace just the burnt black box and wire?
2. Does it need soldering?
3. Should we replace the whole circuit board?
4. Where should we buy parts?
5. Is there an underlying cause of this that needs fixing?
Thanks for all the help.
