Smart hose timer internal flooding
I’ve got water flooding into the battery chamber of my Rachio smart hose timer. I’ve been through this in the past with two units that Rachio replaced, and I am starting to wonder if it’s me or Rachio that’s to blame.
I am currently running four timers. Three of the timers are trouble-free. The one that is malfunctioning was bought at the same time as the two others that previously failed, so perhaps there were manufacturing issues with that batch? I’d appreciate any insight that the community might be able to offer, as this is starting to drive me mad.

Same here. Twice. First time I thought maybe I could’ve incorrectly installed the battery door. Lots of corrosion inside after 45 days, device quit working. After cleaning thoroughly, I installed fresh batteries and battery door and ensured everything was snug. New batteries completely rusted/corroded within 45 days again, and again device quit working. Obviously this unit’s battery compartment is not waterproof. Frustrating!

Same problem. I’ve only had this device a few months and it’s already all corroded inside. Doesn’t seem like the waterproofing works well enough

I have only 1 timer and I have the same problem with it flooding and the batteries corroding.

Hello,
I seem to have a similar problem with the battery compartment. When I went to swap out the batteries the compartment had water inside.
I am quite sure that it was installed properly and I am not subject to freezing temperatures.
Been less than 6 months so did not expect batteries to be expended already… installed in June.

Hi- I too am having the flooding issue. The two valves I’m running were showing as disconnected and I found the flooding when I thought it was a battery issue. I turned out the two screws holding the battery compartment to the valve body. The design is such that the flooding was confined to the battery compartment, and the circuit board and solenoid are sealed. Tried to capture in the photos.

Hello - I purchased 3 of these and 2 of them are having this same issue - water coming through the chamber and the batteries corroding. I also made sure the screws were tight. I have additional videos of the timers on with the water pouring out.

I have (2) timers and both are having internal flooding and the batteries are completely eroded. What do I do?
