Title: Leisure hot tub display flashing Sn, sometimes it flashes Sn along with the temp
Post by: ctroxtell on December 09, 2018, 01:30:48 pm

The Leisure Bay says it means the Balboa sensors are out of sync. It has a Balboa VS240R Part # 55035 control board, how do I sync the sensors?

Honestly don't know or have read this link too carefully but it may provide overview or detailed help.

I would guess that means it's a bad sensor.  What brand of electronics does it use?

I did a copy and paste of;
Balboa VS240R Part # 55035

Goes right to images of the Leisure Bay board and the Balboa heater.

The troubleshooting tree at the servicebalboa link is pretty straight forward for step by step on Sensor sync diagnostics and testing, just a few steps, ie: If this …. then do this or test this etc... takes you through a few steps, pictures or diagrams and all.
Always nice to hear a follow up down the road if or what worked out.
Best of luck !
