Hello all,

We have a 2018 Sundance Cameo 880. The breaker started tripping yesterday after a drain and fill. It was working fine before. After sitting all day with the breaker off, I turned it back on and it fired up and an as normal for about 10 minutes. Then it tripped. I unplugged the heater from the circuit board and the resistance reading between the two terminals was 10-11 ohms, which seems to be in the acceptable range from what I've researched. I turned the breaker back on with the heater unplugged and it seems to be running normally. As soon as I plug the heater back in to the circuit board it trips. What else can I look at that is heater related, before buying a new heater? Thank you, Shane.
 
Welcome to TFP.

You likely have a GFCI trip on the CB which checking heater element ohms will not tell you about.

Visually check for leaked or corrosion around the heater. Any signs are likely the cause of the GFCI trip.

Thank you for the reply. I will pull the heater off and take a look. From your response, I assume the ohm reading is within the normal range then?
 
C,

Your heater is bad... It is leaking a little voltage to ground through the water and this pops the GFCI.. Terminal to terminal means nothing in this case.

Sorry for your loss.

Ok. If it's the heater shorting to ground the gfci trips immediately, since one leg is on as soon as the spa gets power. It's probably not the heater.
The ozone/uv will often have a time delay after start-up, used to be 10 minutes on certain controls.
Breakers with loose connections can cause nuisance trips. Check all screw terminals.
Issues are more likely to occur at start-up. Cold water shrinks gaskets and o-rings and makes plastic brittle, pumps and heaters run for extended periods to heat it up, water gets on equipment, breakers overheat from hours of high amp draw, and so forth.
Frankly, I'd suspect the breaker before the heater.
Keep us posted.
