Smart hose timer internal flooding

Post by Fymaxwell on Jun 26, 2024

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... 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!

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.

Been less than 6 months so did not expect batteries to be expended already… installed in June.

I’m having the same issue with internal flooding while my other timer is perfect

I have the same issue in one of my devices, but both of them are not working as expected anymore. Water leaks from inside the device

Hi- I too am having the flooding issue. The two valves I’m running were showing as disconnected...

Wish I would have searched here before throwing my old one away... I too had internal flooding into the battery compartment.

@wodentx Sorry to hear about your poor experience. I would make sure the battery door is screwed down tightly...
