Breaker trips after 2 minutes - heating element?

[livin]

I emptied my hot tub for the summer and today starting it up again (refill, etc).

Looks like the heater is causing the breaker to trip... as soon as i see the heater light turn on the breaker trips. (It ran for 12 months prior without issue)

... is there a fix for this other than buying a new heater?

... the heater element might have been dry, or sitting in dirty water for 3-4 months BUT




When I turn on the breaker (one next to the tub) I don't get error codes, just this: 137 - 65 - 24 - 24 - PR
I primed the pumps and let it run for a few minutes – that went fine - does not trip the breaker.



I can turn it on and let it run for almost exactly 2 minutes, then trips the breaker (one next to tub, not main panel) - I think because the heater kicks in after 2 minutes?
I can get it running again by turning off/on the breaker – I don’t get any error codes.

I tested:
temp sensors… 40ohm – based on the temp/ohm chart this is correct for the water temp
heating element… 12-13 Ohm





Thank you for the help!

Yes, it sounds like the heater element. Usually, you can just replace the element, it depends on what type of spa and equipment you have. Got type and model of spa?

What is the normal OHM reading on Balboa M7 5.5KW? The OHM reading is 12-13... so it is not broken. Could it just need a cleaning?

The spa is a Keys Backyard 211D... uses a Balboa VS510Sz
