Balboa EL8000 M3 expander board relays clicking pump 4 not working


Recommended Posts

I purchased a used Hawkeye spa 2012 used non functional, worked on by previous owner. I reinstalled new EL8000 M3, ML900 w 4 Jet lable, and 53680 expander board. 4 pump system. All pumps and systems function as they should except pump 4.  Pump 1 two spd, pump 2,3,4 one spd 240VAC. Dip switch config A1 off 2,3 on 2,5,6,7,8 off 9 on 10,11, 12 off B1 on 2,3 off 4,5 on 6,7 off 8,9,10 on 11,12 off. With the expander board connected white lead J95 240 VAC black lead J33 12 V and Exp I/O connected. When powered up systems start relay clicks and then expander board relays continous clicking, no pump 4 activity. continous clicking will stop when EXP I/O is disconnected. Have verified pump 4 is operational by swapping connections on main board pump 1. I'm missing some config and can't find any additional info on balboa site. Thanx in advance for any help.

I also posted this in Swim Spa forum but this system is used in types of spas

Cheers

Ed

Pictures of the boards and of the wiring diagram please.

I posted a few documents, pics and configs. when I get a chance I'm going to switch B6 and B 12 on. I think that with the expander option I might have to put "Option" mode on. I don't have a blower or a blower button

Usually you do need to put switch in test mode or option mode to get it to take.

If it ran before without issue don't change any dip switches and the problem is likely elsewhere. Always power off before making changes to dip switches

It did not,

Now need to see the circuit board so we can see how things are currently wired

 

As mentioned "I purchased a used Hawkeye spa 2012 used non functional, worked on by previous owner. I reinstalled new EL8000 M3, ML900 w 4 Jet lable, and 53680 expander board." I am pretty familiar with the EL 8000 board but only up to the three pump standard config. I've had it in several other large tubs before. The module and control setup is the orignal config, but with new modules, before the orignal owner canabilized the unit. 

The orginal problem per the previous owner was, no flow, no heat. All the dip switches we turned off. I corrected the base line dip switch config and reset the sensors, power cycled the unit and cleared the error on the orignal EL8000 M3 board. The orignal expansion module was water damaged. I ordered and installed a new expansion module and installed. Did not work. I ordered and installed a new EL8000 M3 and installed per factory default config. I then added step by step the additional configs, ie 2 spd pumps vs 1 spd pumps, 4 pump amperage etc. Everything works as it should except pump 4. I ordered and installed a new control panel with 4 jet button config. Still no pump 4 operation.

I reset the EL8000 dip config to factor default

The expander board and 4th pump is the problem I am trouble shooting. On the ML900 when you push the jet 4 button, I can hear a relay on the EL8000 module clicking, but not sure which one. But  think it is a low current relay to control the EXP control via the control cable to the expansion card.

I'll crack it open again tomorrow and get a pic. and try B6 and B12 config. Earlier I attached the connector mapping as to what was connected where

Here are few pics, I tried the B6 as well as the B12 dip, no luck, reset to off. I have the ozone unpluged (J4) as it is failed

What happens if you plug pump 4 into J6 blower? The link you posted for the new board is now unavailable can you make it available again. EL8000 55064-01_97_A.pdfUnavailable

I did try that and it works, but is only a 10 amp relay, and disconnected after the test. I connected pump 4 to J9, Mister, and pushed jet 4 and it worked. It shouldn't have as that is the mister connector. I then relaized that there is a new control module, main module and expander board. No orignal software config! I'll need to default the dips to baseline and then reconfig software to the orignal state. My error, I totally forgot that with all the new componest there was no orignal software config, go figure. I'll leave the pump 4 in J9 as that is a 20 amp relay and safe there. More to come, thanx for the input and direction, really appreciated. Cheers, Ed
