SFord Posted January 15, 2023 Report Share Posted January 15, 2023 I have a 2015 Hot Spot Rhythm. It's been great until today. Went out to treat this morning and all cold. . Power to board but it clicks with a couple warning lights--flashing red then a green clicks on with some kind "LIMIT" label. The display isn't even powering up, so it's dead in the water though power is coming to board. I remember hearing the pump be a bit loud over the last month or so maybe it went out? Ideas?

ratchett Posted January 21, 2023 Report Share Posted January 21, 2023 If you're comfortable with a multimeter you might want to test the temperature sensors to see what resistance they're reading. Search online for Watkins temp resistor chart but I think it should read between 5000 and 30000 ohms if it's working correctly. Temperature sensor failures are common and easy/cheap to replace. No guarantee that will fix the issue, but there's a chance especially if you saw "LIMIT" pop up - that would mean the tub thinks the water is over-temperature (possibly due to a failed temp sensor) Quote Link to comment Share on other sites More sharing options...
