How to fix Gardena Water Computer with distribution unit problem?

[Waddy]

Hello,

My Water Computer stopped passing water so I received a new one via warranty, I set it up without issue BUT the Water Computer and Distributor are not lined up/Sncyd which means its watering the wrong area.. Its not switching to the correct port.

The problem is if Schedule One is watering the distributor port may be watering 5, when schedule one should be port one.

If I press the Water now button, then stop it, then do it again it does switch ports meaning it does cycle but not to correct port when automatic using the Computer. 

I am using the 6 ports and all are enabled.

I have read the manuals multiple times it says press button on bottom to cycle through not work.

How do I get these back to sync, ie. Schedule 5 - waters on port 5.

Thanks.

Hello @Waddy 

Welcome to the Bunnings Workshop community. It's sensational to have you join us and thanks for sharing your question about your Gardena water computer.

It sounds like your Water Computer and Distributor are out of sync, so the ports aren’t aligning correctly with the programmed schedule. Since the distributor does cycle manually when you press "Water Now" twice, it confirms that it's switching but not matching up properly when running automatically. To get them back in sync, try resetting the Water Distributor by pressing the manual cycle button until it reaches port one. Some models require holding the button for a few seconds to fully reset.

You can also manually trigger a full cycle by pressing "Water Now," letting it run briefly, stopping it, and then pressing it again. Repeating this process a few times can sometimes realign the system. If that doesn’t work, try power cycling both the Water Computer and the Distributor by removing the batteries for a few minutes before reinstalling them and setting everything up again. It’s also worth checking the manual for a factory reset option, as that might restore the correct synchronization.

Since you’re using all six ports, double-check that none have been accidentally disabled in the settings, as this could be causing unexpected skipping. A good way to test if everything is working correctly is to set up a short schedule where each port runs for a minute and watch to see if the distributor cycles properly. Hopefully, this helps get everything back on track.

If you have any other questions we can help with, please let us know.
