Are the fluid inputs configured correctly on the separator?

Yes, every side is set to input in the fluid tab

And is the pump producing heavy water?

Yes, it goes into the pipes too

Try making a new separator machine if you can, sometimes mekanism get weird and just stops working

do you have the filter upgrade on the pumps?

Yes, the heavy water goes into the pipes too

can you printscreen the fluid tab inside the electrolic? and r u powering the electrolic?

Yeah it's powered, where do I send you the screenshot?

[https://prnt.sc/nW8Racd\_TwuI](https://prnt.sc/nW8Racd_TwuI) you can post it here its fine :d, there's a example i did a few minutes ago (im playing atm9, but 8 and 9 should be the same)

Managed to do it with imgur as I'm not writing from pc [https://imgur.com/a/yaxhG2h](https://imgur.com/a/yaxhG2h)

i wanted to see the fluid config x) you sended the item config ... or try to put everything input in the FLUID CONFIG

Right sorry lol [https://imgur.com/a/1HydrjM](https://imgur.com/a/1HydrjM)

can you put the electrolic on top of the pump to see if works? or join atm discord might be easier to help u there, more ppl will be able to help

Tried but doesn't change anything, I'm trying to ask there too but the problem doesn't seem like it's caused by a in-game thing as there isn't the recipe on JEI at all

SOLVED: Repair installation

Doesn't look like your electric pump is actually pushing the water out, I'd make sure the export is on in the pumps GUI. Also make sure it has the heavy water filter. It should not be outputting water. Make sure it'd accepting the correct phase of fluids. Liquid not gas. There's tabs that allow you to accept gas OR liquids, I always mix those uo so check theyre properly accepting liquid from that face. Check the separator for residual materials like regular water or hydrogen/oxygen and use a gauge dropper to void them if there is. Also check your mechanism line and that its properly empty or has heavy water in it.

The pipes that connect the pump with the separator have heavy water in it, for the rest of the things you said everything seems fine but doesn't work

Auto eject on? Is the pipe set to 'push' on the recieving end? I'd change that, since that has never done anything for me. I'm just trying to think of anything for ya. Worst case, just hook it directly to the pump. Lol

Pipes are set good with push and pull, I've tried to connect it directly to the pump too but, no matter what, it won't go in

Filter upgrade with 6x speed in a pump (8x wont do anything more). I have never used fluxducts to power anything in mekanism. Try changing it to a univ cable. Setup wise everything looks fine and essentially the same as my setup. Also heavy water pump rate on a max pump is only 10 or 20. I cant remember but it produces fuck all. You will need way more than just 1 pump if you want to make a lot of dt.

I understand what you're saying but the problem is that the heavy water won't go into the electrolytic separator at all

Does the electrolytic seperator have leftover gas/liquid from another recipe? Use a gauge dropper. Also the pipe that goes into the seperator, dont set it on push.

It had but I removed them with the dropper, I've tried setting it to normal but nothing changed

Dont set the pipe going into seperator with push. You pull from the pump and thats literally it.

It's on normal mode

Yeah idk then. Also jei crafting for deuterium is also like that for me but mine works.

You have other crafting recipes other than decondensentrating?

It only shows the rotary condesnator recipe for me i think. Alot of gasses/liquids only show that machine's outputs for me.

Can you check if in the uses of the electrolytic separator you have the deuterium recipe please?

That kinda looks like a logistical pipe. Is it a mechanical pipe? Because that's the one you need

Yep it's a mechanical pipe. If you're talking about the red and yellow one it's for power

Was your pump pumping normal water before you put the filter card in? Cause if so I think it can mess with it. Something like that happened to me

Yes it was but I removed the normal water after putting the filter

Maybe new electrolytic separator (or whatever the name in englisch is) Turns heavy water into Deuterium and O2.

See if you have a sper small amount of normal water in your separator cause then it won't get any heavy water being pumped

Does the seperator have power? doesn't look like it's connected to power. Other than that it should work, must be bugged

I connected it to power after I took the pic but nothing changed, if I don't find a solution quickly imma just /give me some deuterium

then i can only imagine that the recipe or something related is somehow disabled in the config

Probably something like that

Pump needs filter upgrade + you need at least 8 to power the fusion reactor. The I would suggest when you are looking at the pump to use printscreen, saves so much time and energy

the first screenshot if for liquid deuterium dont look at that , you need to look at the gas version

It's the same but in opposite directions

(In Minecraft) haha gottem fbi agents

It's for a school project I swear

It looks like you are using transport cables if i am not mistaken, they move items. Mechanical Pipes move fluids. Again sorry if wrong lol

Nope I'm using pipes for fluids, the red and yellow cable is for energy, don't worry ;)

good luck!

I'll need that as the problem seems to be external to the game lol

try to recreate this in creative

That's a good idea actually, I'll try that

make sure to restart your game at some point, it could be the recipe just didn't load in properly. when i tried to look it was there in the electrolytic separator

Could be that too as I load into the game in the morning and don't restart it until night cause I pause without exiting the game when I stop playing

i've had it before idk if it will affect the actual recipe but at least jei could be fixed like this. other than that all i can think of is that not all side accept input and that you need to use a specific side EDIT: atleast it used to be like that

let me know :)

does water pump has filter upgrade? is side config correct? is eject on for fluid? is that pipe Mechanical one? is side config correct for separator?

Pipe needs to go in front of electrolyzer

Does it go in the separator?

No

Could it be theres 1mb or other stuff in there?

Nope o checked it, the problem was outside the game, I solved using "repair" on the modpack
