If water ever freezes in these, you'll get that problem. could also be dirt, but most likely water froze in there at some point. also check for weak battery if present.

My gardena water timer won't stop bipping. See the picture. Is it the battery ?

for the Gardena-T-1030-1805 model....
Gardena 1030 1805 Operating Instructions Manual Page 7

11. Battery
11.1 Status indicator
If the battery capacity falls below a certain level, a warning signal sounds every 15 seconds. The programs you have set are not run. The water flow cannot be opened manually. If a valve is open, however, it will be closed.
11.2 Changing the battery
If the battery capacity is too low (the warning signal beeps every 15 seconds), you must change the battery.

To do this, the water timer must be removed from the tap.
Important : Changing the battery deletes the data you have set.
To change the battery :
1. Insert the battery in the battery compartment
2. Set the Run Time control knob
3. Reset the watering data as described in "Setting the watering data".
3 If the Run Time knob is not turned to Reset, 5 seconds after the
battery was inserted the current Run Time shall be accepted. This is confirmed by a double beep.

Note : The time the battery was changed is taken to be the starting time.

To ensure that the water timer works properly we recommend that you insert a new battery at the beginning of every gardening season, or at the latest after a year.
Important ! Please dispose of used batteries properly at the appropriate communal waste disposal site. Only dispose of batteries when flat.

We need a replacement part for our Gardena Garden timer. The part we need is a Rubber diafram. It is black and it has a post and spring going through the center of it. Where can I get replacement parts?

I don't have a source of Gardena parts, and have asked anyone finding this thread to add a comment if they find a Gardena parts source.
Compounding the problem is the company doesn't respond to e-mail requests, many Gardena products do not have on-line manuals, and Garden timers sometimes have more than three different numbers for the same timer making it difficult to identify exact timer.

The timer lights blink together slowly and rhythmically, but the timer doesn't respond to the program button being pressed.

I can't be sure but on the model 604F, this indicates the battery needs to be replaced (on 604F it's a 9V battery).

When is ON the timer admit a water jet and after that the valve is closing even if the battery is full, the timer ON and the supply of water open. Thanks

Problem is not clear and timer not identified.

Open following link for Gardena resources including contact information for Gardena.

If timer is cracked, then electric parts can get wet and stop working.
If timer valve is not closing, maybe the timer is broken or something is stuck in the valve.

We set the timer and the battery is fine. When we turn on the faucet the water runs through the timer non stop

Hi Karen,
Fixya promises a fix, but some things are broken and can't be fixed.
I suspect that is the case here.

Sounds like the water valve might be stuck open.
Or the battery contacts are bad, a wire is broken, the clock motor has worn out, the internal on-off switch has worn out, electrical short, a piece of plastic has broken, a rubber gasket is broken or twisted in the way, sediment or minerals have built up in the valve. Or a combination of factors above.
Leaving valve exposed to freezing temperatures will crack the plastic.
Clean the waterway with CLR calcium lime rust and see if problem is solved, but immersing valve in CLR solution will not be good for electrical components.

I have not read any internet post where somebody says they repaired a water timer after timer has gone bad. This is true for all brands. I am looking for that information, and actively seeking factual accounts.
Since many other people have problems with Gardena valves, add a comment and say what you did to fix problem so everybody finding this link can share your solution.

Open following link below for some Gardena resources, including link to parts.
I do not know what parts to suggest, nor do I believe part replacement will solve problem.
I can't find sellers of Gardena parts, and the Gardena contact-us page doesn't respond back as of right now, but things are continually changing and folks visiting this link can update the post with their solutions, and add links to sellers of parts that would be of value.

Generally speaking, except for some timers from Intermatic, Paragon and Tork, there are no replacement parts for timers.
I am not sure what manufacturer makes the timer mechanism for Gardena.

Which gardena water timer will work the best?

Generally speaking, fixya sees more complaints about Gardena water timers than other brands. Maybe more Gardena timers are sold, or maybe the timers have problems.
There are no sources for water timer parts for any brand, and nobody reports being able to fix a water timer once it goes bad.
Any plastic outdoor device that works with a battery-operated clock motor cannot last more than a year or so, and will crack if exposed to freezing water.
I suggest the cheapest timer.

My gardena timer suddely has a restricted water flow its the mechanical one thar has lasted about 15 years are parts available Ithink it may need a new diaphram.......Al

No joke, that is the longest I have ever heard of a Gardena timer working. I suspect you are correct about the diaphragm, but there is not much hope of finding new parts for that model. I suggest celebrating your amazing feat with a new (not as well made, sadly) Gardena timer and keep an eye out for a part at a garage sale to fix the old one when you can. I suspect you take very good care of your tools. So few people do anymore. Regards,
