Here is my circuit board. I'm concerned it may be the board. I disconnected both pumps and tested it. 240v is sent to both Jet 1 & 2 terminals regardless of which jet is turned on. It may be nothing but I also noticed with both jets off each set of terminals also gets 16-24v continuously.

Several years ago I replaced Pump 2 after some tripping problems in a 2004 Caldera Utopia Geneva. Things worked great. One day I noticed that whenever I started Pump 2, Pump 1 would come on also. I swear it didn't work that way before. I haven't had any problems with either pump but it doesn't seem right. Can anyone confirm if this is normal and if not point me towards where to start troubleshooting.

I have a much older Caldera Geneva and quite some time ago after my wife drained and filled, I noticed bubbles coming out of the heater line. I can hear it in the line and if it was just annoying that would be fine but ever few days it kicks the watchdog and I come out to find a the flashing dashes. I've burped from the pumps and even drained & refilled but its still there. Any thoughts on the best way to purge the heater line of air?

By the way I asked a local Caldera dealer specifically if they shared a relay and they told me 'the control board has no relays'. I stopped talking to them. Is there a schematic for the control board somewhere?

As an update, I opened jet pump 1 and found the starter capacitor had a small hole just shy of the middle of the base and between the two terminals. I would have just replaced the capacitor but I decided to inspect the wet end. The impeller shaft had a small crack in it. Neither would be an expensive fix but given the age of the pump I just replaced it. I've never seen a capacitor do that but the new pump works fine. One additional question I had, the new pump has a low speed and the control board has a Jet Pump 1 Low Speed. If I ran an additional wire is there a jumper setting necessary that would let me run jet 1 on a low speed?

I did some troubleshooting and found Jet Pump 2 will come on if Jet Pump 1 is disconnected as seen in the picture. However if I connect Jet Pump 1 and disconnect 2 I can trip the 30amp breaker by trying to turn either 1 or 2 on. I was also able to connect 2 to the Jet Pump 1 connections and turn it on(high) using the Jet Pump 1 button. Does this sound like I need to replace Jet Pump 1 to you guys?

Hi all, We recently got a 2004 Caldera Spas Utopia Geneva from some friends, built a deck and had it wired up but I'm having a problem. After turning both the 30 and 20 amp breaker on, the spa starts up. The 'LIM OK' light comes on and the 'HTR OK' as well. The circulation pump starts working and after 5 minutes it goes into the auto clean routine. The air blower starts and runs for a minute but when Jet 2 turns on low it trips the 30 amp breaker after a second or so. If I manually start Jet 1 or 2 it trips near immediately. I released the union on top of both pumps and only found one to have a small amount of air in it. I know several have stated disconnect each component and then try but if the air blower and heater can start without tripping either the 30 or 20 could it be one of those? I'm just puzzled as to why both pumps would be bad. As a test the electrician bypassed the 30amp GFCI breaker and wired the 10AWG lines directly into the main 50amp feed coming into the subpanel. The pumps will run fine that way but it's not a permanent solution. Does this point to a GFCI issue? The load neutral is connected to the 30amp breaker. The only wiring deviation is a convenience GFCI outlet wired off the 20amp breaker. The electrican says he tried running it with that disconnected with no luck but I wasn't standing over his shoulder at that point. We know the tub was sitting for some time so the goal was to run it long enough to heat the water and then use a jet purge and drain afterward but if I can't get the jets to run without tripping. So that's not an option unless I go back to that 50amp GFCI bypass just for cleaning if that's recommended. I know you guys get a lot of random drop-in 'Help' questions but any advice or direction is helpful. At this point we have several thousand plus dollars into a non-working hot tub.
