Maintenance

Almost all multiblocks work with the maintenance system of Gregtech. A multiblock may generate random maintenance issues, which need to be fixed. If they are not fixed the multiblock will consume more power, or in the case of a generator, generate less power. If too many maintenance issues occur, the machine won't work any longer.

The machine's controller will display messages if maintenance is required, along with **HAS PROBLEMS** in red when the Waila tooltip is checked. Five of the six maintenance tasks are done with basic tools, while the 6th requires a Soldering Iron. Alternatively, Duct Tape can be used to fix all of them at once.

Maintenance Hatch
The usual Maintenance Hatch is the first tier Maintenance Hatch in the game. They should not be shared between multiblocks if you want to wallshare them. To fix them you can either use BrainTech Aerospace Advanced Reinforced Duct Tape to fix all issues, or use GT Tools to fix them one by one by clicking with the tool in the Maintenance Hatch GUI. Another option is right-clicking on the hatch with a Tool Box (IC2) containing the needed tools to fix all issues, which will fix them all at once.

Auto Maintenance Hatch
The Auto Maintenance Hatch is the higher tier version of the Maintenance Hatch and gated to LuV. It needs to be supplied with 4 Duct tape, 2 Lubricant Cells, 4 Steel Screws and 2 HV-Circuits. But will fix any occurring maintenance issue instantly.

Auto-Taping Maintenance Hatch
The Auto-Taping Maintenance Hatch is the highest tier Maintenance Hatch. It is gated to UV-tier and rather costly. However once build you no longer need to worry about any maintenance occurring, without any running cost! When wallsharing multiblocks the Auto-Taping Maintenance Hatch may even be shared between them without an issue.

BrainTech Aerospace Advanced Reinforced Duct Tape
This single use item can be crafted starting at MV, and solves all current maintenance issues of a multiblock machine at once and visually changes the hatch's appearance. It does not stop future maintenance issues, which will require more tape or tools.
