LOCKF on Coast Spa

[CPG]

I recently purchased a second hand Coast Spa hot tub (approx 8 years old). It has been working fine but I managed to somehow inadvertently lock the keypad and am completely stumpted as to how to unlock it. I have pressed the 'Econo' button for 5 seconds as described in the online troubleshooting guide and also the 'Pump1' button. I can only assume because my hot tub is an older model that these unlocking methods dont apply. Unfortunately I do not have the manual as the previous owner misplaced it. I have contacted them and am hoping it can be found. In the mean time any suggestions you have would be gratefully appreciated

I know this is an old post, but I have the exact same problem on my Gulf Coast LX 11000.

Did you find the answer or does anyone know the solution?

Arctic Spas have a LockP - LockF and Unlock.  One our tubs you have to push and hold pump 1 for 5 plus seconds to go thru these options.
