Issue Title

Ore Wash Plant not working in Chemical Bath mode

Expected Behavior

As discussed briefly with Alk - I have set up the Ore Wash Plant in Chemical Bath mode but I can't get it working.

Current Behavior

I've encountered multiple bugs:

1. When the Ore Wash Plant is formed in Ore Washer mode, the input hatches won't accept Mercury. To fix this, I had to break the controller and input hatch, place the controller and set mode to chemical bath FIRST, then place the input hatch so the multiblock forms.
2. Once the multiblock was formed, I fixed all maintenance issues, powered it and put some crushed nickel ore in. But nothing happens.

Game Environment

GTNH Epsilon - 2.0.4.6

Has anyone got this to work? If so, what did you do?

2.0.5.1, Prospercraft server. Same issue, Chem bath mode non functional, attempted several but was really after Zirconium

worth noting we're still on 2.0.4.6 so I'm not sure if it is anything to do with the same issue where Centrifuge recipes don't start

Was either fixed by 63b22ce or 0fbf214.

In version 2.0.5.1 this isn't working.

I have tried switching modes and running it.

I have tried to fill the ore washer with water, place the controller and switch mode before placing the final piece to form and it still won't run.

Any suggestions?

I know this is quite old thread but I made the Ore Washing Plant working in Chemical Bath mode by supplying it with water just like in the default mode. It does not require water afterwards, it just has to be filled up with it.
Hope this helps.
