As players travel with Ashley in Chapter 14 toward the end of Resident Evil 4 Remake, they must solve a puzzle by rerouting the Waste Disposal's power before moving forward. Similar to puzzles seen in the Dissection Room and the Freezer Room, players need to align power lines from a computer in the right direction. With the game's monstrous Regenerator threatening to kidnap Ashley at any point here, players will have to figure out a solution quickly.
The Waste Disposal area remains blocked by an Electric Lock Terminal door, with a computer terminal nearby that only activates when players pull a Power Control Lever. This Lever sits across a bridge only Ashley can lower with a wheel, but players should know that multiple enemies and one Regenerator spawn when this mechanism is pulled. Therefore, those looking to get an S+ Rank on their run should be prepared with the right weapons and gear for this area.
How To Solve The Waste Disposal Power Puzzle
A box labeled "Power" has a line at the very top of the computer terminal, which goes to various nodes that the player may rotate however they wish. The goal should be to connect every line to the system's middle icon and every lightning symbol. This may take some trial and error, but players who take their time should notice a strong pattern to make power flow in the right direction.
Players have to rotate nodes on a computer terminal to make power flow through lines from the top of the screen to the center to solve the Waste Disposal puzzle.
If the terrifying Regenerator monster of RE4 Remake happens to pressure players into solving this puzzle fast, a swift answer would be to move the first, second, and third node from the top three times, then rotate the fourth icon down twice. This shifts the nodes into the right positions to power the computer terminal, shown by the electric symbols glowing when connected to different lines.
How To Solve The Waste Disposal Puzzle On Higher Difficulties
This puzzle changes depending on the difficulty, with four power lines on Assisted mode and up to six on Hardcore or Professional. While the easier puzzle can be solved through simple experimentation, the more challenging one may take far more time.
A quick solution for those struggling on Hardcore difficulty would be to press the first node two times, the second node once, and the fourth node two times.
Sliding the switch to the yellow power area at the bottom of the terminal unlocks the door at the end of the area, allowing players to continue to the final sections of the story. Learning how to solve the Waste Disposal Power puzzle in Resident Evil 4 Remake signals the last non-combat obstacle for players to overcome before the game's conclusion.
