ANS CO2 Solenoid Stuck Closed

**aquanick** · 15th Mar 2016, 10:09

Guys,

My ANS Co2 solenoid is stuck in the closed position, gauges show the pressure in the regulator however nothing out from the bubble counter.

EastOcean is advising to replace the entire solenoid for ~$50.

Any one had a similar issue and managed to repair the solenoid?

Thanks in advance.

I have similar issue before (but not with ANS), infact just last night :P :P :P

Just switch off and remove the regulator from the canister, remove the solenoid which is actually very easier, using an Allen key or just turn and unscrew the solenoid. (Depends on the manufacturer of the regulator)

1) Dirt & Debris
You will find the solenoid is actually a very simple device, it have a piston and a coil spring. Check if there is some dirt that require cleaning.

2) Height of the piston to the regulator
The Cylindrical rod need to be able to extend itself when energize and it have a working distance to be able to function properly. One common problem is over tightening of the solenoid to the regulator or under tightening. So just trial and error and see if the by tightening and lossening of the solenoid helps. If it does, most probably, the thread are worned, just use a plumber white tape to wrap around the thread and tighten it again to the desirable height.

3) Solenoid Not working
After you take out the solenoid from the regulator and switch it on & off, if the piston does not even move, you have a spoil solenoid. Get a replacement. (when testing the solenoid please have something infront of the piston just incase the piston shoot out...lol)

Hope this helps

Thanks RealCaster, I did open up the solenoid, the 4 screws on the side and I could see that the piston is kind of stuck blocking the co2. No dirt or debri.

May be your coil or electronics inside the solenoid is burnt, it maybe better approach the LFS such as east ocean to check it out.

Got a new solenoid regulator.. Is it safe to change the solenoid regulator at home? Or should i carry the whole tank and regulator to a lfs? :/

For the benefit of everyone who has a ANS solenoid regulator, if your solenoid gets stuck like mine did; then the easiest way to fix it is to open the 4 screws on the solenoid and remove it. On opening if it makes a sound that means the pressure built in is released and that is a good sign. I used a vacuum cleaner to clean it up and installed it back and it works.

Also, it is handy to have a big spanner at hand and remove the regulator when you are doing this.

Cheers.

Nice to hear that, so you have a spare solenoid regulator

**aquanick** · 21st Mar 2016, 19:27

Nope, just a spare solenoid from eastocean. The regulator was working.

Now i am thinking why not buy another regulator and set up a new tank.. ��

didn't mean to hijack but I have issue with my solenoid as well recently. but my case is exactly opposite. My co2 does not "close" meaning co2 keep flowing out despite no current supply. any idea if cleaning it helps or I really need to get a new solenoid ?
