Watchdog error - sundance

[calsap]

Hi All,

Need some advice. My 2001 Sundance Capri gives a watchdog error after being off a few weeks.

It gives a watchdog error right away on startup. Dashes and other text are flashing. I opened it up and found mice had eaten through the temp sensor wire. I wired it back up. Checked the capacitors and they look fine. 

I figured fixing the wire would fix the issue. Flo sensor and hi limit are fine. Turned it off and on a few times and still the same, even waiting overnight. 

The error and the chewed wire seemed like too much of a coincidence for something else to be the issue, but the error won't go away. Any thoughts before I change the capacitors anyway?

Thank you!

What other text?

I would be changing temp sensor before capacitors.

I checked the resistance on the temp sensor and the high limit and they both checked out. 

The filter was out too.

The screen doesn't just show dashes. The am/pm/lock small text were flashing. 

Thanks

According to what? How many ohms on each?

I was looking at the chart here.  https://www.spaandpoolsource.com/sundancespastemperaturesensordiagnostic.aspx

The spa had been off and it was around 70F outside. I think the readings were around 35kohm for the temp sensor and 30kohm for the hi limit.
