Could you please advise where I may find out how to reset the control on my coast spa?
The display is showing SER periodically, and it will not display the temp. We purchased this spa second hand however all elements of the spa work just fine. We did download the manual off the internet website, however, no explanation of how to clear the 'ser' off the display... :confused:
Anyone that can offer a solution, other than calling a dealer, will be greatly appreciated... :)
Regards...

Try killing the power at the main panel for at least 30 seconds and then turn it on, its like a reboot.

Thanks for your input. It did work after flipping breaker. :)

Glad I could help.

Try to press and hold pressed the "light" button for 3 to 10 sec - should reset the "SER" in the possessor of the SPA (I've tried to call the Cost Spas service department but they didn't tell me that instead they suggested to send me a teck - what a crooks, they know for sure of this as it is a tech mod to reset the "SER" - service reminder message after the 8000 hours of the operation after ech done)

WERFWER,
Thank you for the fix to my problem. The reseting of the breaker did not work for me, like the previous advice suggested. Your advice did fix it by holding down the light button for over 3 seconds. You have saved me so much time trying to figure this out.

Try to press and hold it pressed the "light" button for 10-20 seconds, this should reset it or try to shutdown the power at the main panel for at least for a minute and then turn it on, its like a restart to a system.
