Dude!
You are a life-saver. My 2007 Sundance 880 series went into watchdog mode when I changed the water in cold weather. I checked the capacitors as you suggested and found one of the two had a slightly bulged top.
I should add that my local dealer serviceman here in upstate NY didn't get back to me for 4 days. I put a space-heater in the drained tub so it wouldn't freeze per the counter-girl's suggestion. When the service guy got back to me, he started quoting costs just to come out and look it over. He never showed when he said he would. I complained to the dealer and the service technician (if you want to call him that) seemed put-out that I was bothering him. I asked if he stocked replacement capacitors. He said they just replace boards at $600.00 ea. (without labor and service call fee).
Long story short... I called my local electronics store and they set me up with 2 new capacitors for $5.00 each. I pulled the board and had them replaced (easy job) in 15 minutes. Board remounted following the picture I took before disconnecting everything. I filled the tub and turned on the breaker. Instant start-up and all indications in the "green".
Back in business for $10.00 and no service call or new CB!!
You are the man! Thank you very much.
I will be taking my business to another dealer in the future.
