Sundance Spa Heater issue

Hi, I have a 2004 Sundance Bahia. Recently having heater/display issues. The display showed approx 8-10 degrees less than actual water temp. Now the other day it showed 20 warmer than what it acually was. This Morning it was right on but later shut it self down and displayed --- which means something is wrong according to the owners manual. Do you think it could possibly be the thermostat? Any help is greatly appreciated.

Welcome to the forums !

It sounds like the temperature sensor needs to be replaced.

You may also have to replace the hi limit/freeze sensor because it's shown as being attached on a combined plug with the temp sensor.

Link to your unit in case you don't have the manual:
