[2017 Caldera Paradise Martinique not heating]

Before you go pulling the boards apart turn power off to the spa, pull the filters out, turn power back on and see if it starts heating. if not, let me know and we will go to the next step

 

[2014 Beachcomber Hybrid]

Is this model also T&G individual pieces for the siding ? I have repaired a leak at the equipment which is an outside compartment located under the steps but it still has a fairly good leak somewhere opposite side from the control panel/equipment side. If it is T&G there must be a starting point.
