Sundance maxxus pump identification

[thunder71173]

I have an 07 sundance maxxus.  The main board and panel were smoked when I got it and I had to install a new main board.  I am re wiring it and I can't find any information on which pump is in what location in the cabinet.  Because I had to disassemble everything I just need to know which pump are 1 and 3.  pump 2 goes through the t 92 relay so it has spaded connectors.  I believe pump 1 is a two speed pump and pumps two and three are 1 speed from reading on other forums but that information could be incorrect.  Any help would be great because I am getting a single speed only from the first and second pump button and they operate the same jets on the front of the hot tub.

The white sticker on the pump... RPM will have one number (3450)for a single speed and a 2 speed will have 2 numbers (high speed and low speed RPM. Also a single speed will have 3 wires and a 2 speed will have 4 wires. Post photos of the schematic on the inside cover of the pack

The pump you are showing is a single speed pump.

If it's bad, find a 240V pump that draws 12 amps with a rotation speed of 3450 RPM. It doesn't have to be the exact model that you have as long as the specs are the same or really close. 

This one is the same pump as you have. https://www.amazon.com/LINGXIAO-SPA-Pump-Single-Speed/dp/B0BMYXJXHS/ref=sr_1_2_sspa?crid=R0M4TO6UCM92&dib=eyJ2IjoiMSJ9.BCX7v9F3K_pwLKHnfZMiSpLICc0hHQEpNKrtK3-NOL4.M4vOUzxrbDIhB9v3BX5-M-EuxnP_Nzicdf_Jy7DEA6E&dib_tag=se&keywords=240v%2B12amp%2Bsingle%2Bspeed%2Bspa%2Bpump&qid=1717017824&sprefix=240v%2B12amp%2B%2Bsingle%2Bspeed%2Bspa%2Bpump%2Caps%2C194&sr=8-2-spons&sp_csd=d2lkZ2V0TmFtZT1zcF9hdGY&th=1

what is the model number of the watch size battery I that picture?

[cranbiz]

Looks like a CR2040.  It's thicker than a CR2032.

[BobMc]

Do you. know what that battery is used for?

No, I don't. That being said, It's probably to keep the settings when power is off. It's an older board which probably does not have a persistent memory.

This board is the latest revision for the maxxus.  It's new and I'm still having the pump 2 and 3 not working issue.  pump 3 is a single speed pump and I know that it works because I plugged it in to the position for pump 1. Pump 2 I have never got to run but I did replace the t92 relay and checked all of the fuses for continuity.

There is a line of dip pins JP19 and JP9 that tell the board different settings. Cover one pin you get one setting cover both pins you get a different setting. So I would guess if it is a new board and you have components that are not working I would check these pin settings to add pumps. Post photo of the schematic on the inside cover

Ive checked and double checked them.  I have done a continuity test on fuse f1 2 and 3 replaced the t92 relay and actually swapped pumps 1 and 3 to verify those two one speed pumps are good.  Another sundance tech suggested the rear control panel might cause the issue but the rear control panel on this one has nothing to do with the pumps, only the lights which also don't currently work. So I have checked

replaced main board

checked fuses

verified both 1 speed pumps work

replaced 2 speed pump t 92 relay

verified board pin configuration several times.

When I push the pump 1 or 2 3 button pump 1 comes on when I push it again to activate pump 2 it turns them off.  I am thinking it's the control panel itself that's bad but thats around a 600 dollar guess

Test for power off board at pump connections. Do you get power off board when each pump is engaged?

[thunder71173]

I havnt had the ability to check that because I can't seem to get anyone with electrical experience to come help me look at it.  What I did notice this morning is on the second push of the button it's giving me the flo message on the screen.

Your spa has a circulation pump. Is it running and moving water? Above the circ pump is the flow switch. When the circ is running the toggle inside the flow switch housing should be pressed up against the post making a connection and no FLO error. If the circ is not running the toggle will hang free and not touch the post giving a FLO error. Now when you press the second pump on does the toggle stay press against the post or does the circ pump stop and the toggle now hangs free and does not touch the post?  Trying to see if pressing pump 2 on is somehow overriding the circ

I sometimes have to use a flashlight in behind the flow switch housing so I can see the movement and position of the flow switch toggle

Who installed the new board?

[thunder71173]

I installed the new curcuit board and i know the circulation pump works because I can hear it cycle when the waterfall comes on.  I have it set to economy.  what I dont know how to do or correct is how to see the toggle on the flow switch.  pictures would definitely help.  If there is a way I could call you please let me know.  my email address is [email protected].

[thunder71173]

I went out and did some more testing.  my circulation pump works but not as it should.  i am not 100% but I think it should work all of the time.  I powered the tub down and disconnected the j7 connecter where the flow switch is plugged in.  I did a continuity test on all of the fuses again then tested the voltage at all of the plug power jacks on the board.  All of them had 124 volts except #8.  #8 is connected to the upper left side of the t92 relay.  pump 2 gets its power from the bottom two tabs on the t92 relay.  I am going to look at the wiring schematic again and make sure the t92 relay to the board is right but my question to you is if the circulation pump isn't running all of the time do o need to replace the glow switch? Could this be my whole issue?

Leave in "Standard" mode until you get it figured out.

The part hanging straight down is the "post" the part offset on the right is the "Toggle". The arrow pionts the direction of water flow. The water flow will press the toggle up against the post making a connection that tells the board that there is flow and it is safe to fire the heater. The flow switch protects the heater from firing when there is no water flow and going nuclear and burning the house down. The circ should come on first creating flow and pressing the toggle to the post next then the heater will work. If the plastic flow switch housing is cloudy and it is hard to see the toggle and post hold a flashlight behind it.

No... The circ should come on first as mentioned. If the toggle is touching the post the spa should heat. If the circ stops running you have a different problem.

You can bypass the flow switch by jumpering the 2 pins on the board or cutting the wire and joining them together BUT DISCONNECT THE HEATER FIRST!!! If you bypass the flow switch and there is no water flow the spa could go nuclear in fractions of a second and burn down your spa, house, the neighbours house... But the flow switch is not the issue at this time so don't.

If you post more photos make sure they are oriented properly... getting a sore neck...lol

[thunder71173]

Since I unplugged the connecter and plugged it back in the circulation pump has been running.  I put it in standard mode as you suggested.  The heater has been working fine since I installed the new board and heater back in May.  I'm going to post picks of the schematic and control box.  the strand thing is my flow switch seems to be mounted upside down.
