Hayward AquaLogic
The Hayward Goldline Aqua Logic automation and chlorination models AQL-PS-4, AQL-PS-8-V, AQL-PS-8 AQL-PS-16-V, AQL-PS-16 use the GLX-PCB-MAIN board.
Goldline introduced AquaLogic in 2003. Hayward acquired Goldline in August of 2004. Hayward discontinued AquaLogic in 2008 and replaced it with Prologic.
Low Salt
Low salt messages are often the first indication of a failing cell. Don't add salt until you verify the water salt level with a Taylor K-1766 Test Kit or Salt test strips.
High Salt/Amps
The high salt warning comes on when the current exceeds 8 amps. This can be caused by high salt but also by high water temperatures. [1]
Check under the diagnostics menu for the correct cell size. If you select the cell size to t-3, t-5 or t-9 instead of the correct t-15 then the salt readout from the controller will be high salt.[2]
Common cause is failure of the solder joint to the K1 relay.[3] The K1 relay does not need to be replaced. It only needs to be re-soldered. To check if this might be your problem, unscrew the mother board and turn it over, if there is black smoke/burn marks at the K1 relay solder point, this is likely your problem.
Tips
- high amps can "blow" the solder joint and that high amps are most often caused by salt levels being too high.
- the motherboard has a 20 amp fuse on it. Unfortunately it seems the Amp limit on the relay is 20 amps too. It has been strongly recommended to replace the 20 amp fuse with a 15 Amp fuse to thus protect the relay and the K1 solder point.
- The K1 and K2 carry the DC low voltage (polarity reversal) to the salt cell.[4]
- The K1 problem causes amps to always be exactly zero.[5]
- Use a 30 watt soldering iron and 60/40% rosin core (solder lead)
- Your don’t have to unhook mother board wires. Just turn it over. Make sure it is level before adding solder.[6]
- There are different versions of the main board. You can find various pictures in this thread.
