How to fix Gardena water distributer and gardena water computer getting stuck?

[abhijeett]

I have a Gardena water distributor, which has four hoses attached to it, and five and six is capped and closed for the Gardena water distributor. The distributor is working with the Gardena water computer. Now, when I turn on the computer manually for water, it goes through a cycle of all the four outlets and then gets stuck at five. For it to work again, I have to open the hose from the top and release the pressure, and then it automatically resets to one. What can I do to permanently fix it and what is causing it?

Hi @abhijeett,

Thank you for your question and welcome to the Bunnings Workshop community, it is fantastic to have you with us.

I can't say I'm sure how to best address this issue, you'll have to allow me to get in touch with Gardena when they reopen tomorrow to see if they have a solution to this issue.

Can you advise which specific water distributor and computer you have? Possibly this GARDENA Master Water Computer and this GARDENA Automatic Water Distributor?

Please let me know so I can provide Gardena with as much information as possible.

Hi @abhijeett,

This is a common occurrence when the manifold hasn't been set up to ignore unused ports. You should find some orange levers on the distributor's inlet side. Look for levers five and six and pull them to the centre, which is the off position. This should prevent the distributor from trying to run the manual cycle through them and instead cause it to return to one after it's done with four instead of getting stuck on five.

Let me know how you go. If that doesn't solve the issue, we can continue to troubleshoot it for you.

I’m having it the same similar issue but I have all six been used and it seems to be skipping 2,3 and 4.

i am on my 2nd device over the last 6 years. Have have gave the orange taps some move ment and even with 4,5,6 turned off it still jumps from 1 to 5. 
any thoughts? 
thank you

Hi @Kōbe,

A warm welcome to the Bunnings Workshop community and thank you for your question.

Start by temporarily disconnecting the water computer and manually testing the distributor. Turn the water supply on and observe if it cycles through all six outlets properly. If it skips, this will indicate the issue is with the distributor itself. If it doesn't skip, then we can focus our efforts on the computer.

Even though you've moved the orange taps, debris or mineral buildup inside the distributor could still block the valves. I'd suggest giving the distributor a good clean before moving on to further troubleshooting efforts.

The Gardena Water Distributor Operator's Manual recommends cleaning the filter and rinsing the water distributor once a year. See the following excerpt on how to rinse out the distributor.

1. Set all flow levers to on and remove the end caps. 
    
2. Open the water tap or set the Water Computer to manual irrigation.
    
3. After 30 seconds, press the dial disc so that the next outlet will be rinsed out.
    
4. Repeat Number 3 for all outlets.

If the problem persists, disconnect the water computer and distributor completely, then reassemble and reprogram them. Sometimes, resetting can resolve internal glitches.

If the problem still persists, the internal mechanism of the distributor may be worn out after years of use meaning it will need to be replaced.

Let me know how you go.
