Why the Laundry Number Puzzle Matters
The Control Resonant number puzzle opens a hidden room in Central’s laundromat, rewarding careful observation with a Health Upgrade Point and collectible documents. Its solution is simple once you realize the paper’s strings of zeroes and ones are a map of the washer rows. A 1 means the corresponding washer must be on, while a 0 means it must remain off.
This is one of the game’s Secret Hideouts, so it is worth completing even if you are focused on the main story. The room does not require guessing a password or finding a loose item elsewhere; everything needed is inside the laundromat.
| Puzzle element | Meaning |
|---|---|
1 on the note | Turn the matching working washer on |
0 on the note | Leave the matching washer off |
| Out-of-order washer | Counts as an unchangeable off position |
| Green display or active light | Confirms a working washer is switched on |
| Hidden wall opening | Indicates the pattern is correct |
The puzzle can feel confusing because several machines are broken and the physical rows are not presented as a neat grid. Treat the broken machines as fixed zeroes, then work through the note one row at a time.
Find the Central Laundromat
The puzzle is inside the Wear'Em & Wash'Em laundromat in the Central zone. It is near East Park Station, south of the Patterned Factory area and west of the station entrance.
If the front door is blocked when you arrive, do not assume the puzzle is unavailable permanently. Follow the nearby streams of floating debris back toward the enemies creating the obstruction. Reaching them may require rooftop movement and a short fight. Destroy the enemies, then return to find the entrance accessible.
Once inside, look at the cork board toward the back of the shop. Two notes are posted there:
- A customer complaint explains that many washers are broken.
- The important note, titled “While You Wait,” contains the number pattern.
Read the number note before interacting with the machines. It gives the complete solution:
| Note row | Binary pattern | Required active washers |
|---|---|---|
| 1 | 0001000 | Fourth position only |
| 2 | 001100 | Third and fourth positions |
| 3 | 100001 | First and sixth positions |
| 4 | 000000 | None |
| 5 | 000000 | None |
| 6 | 000000 | None |
| 7 | 100000 | First position only |
Before starting, it helps to switch off any washer that is already running. A previous interaction, or simply checking the room without a plan, can leave an incorrect machine active and prevent the door from opening.
Decode the Washer Layout
Stand facing the cork board and use the room layout as your reference. The longest uninterrupted seven-washer row is on the back wall to your left. That row corresponds to the first line, 0001000.
Turn on only the fourth washer in that seven-machine line. It is the center washer, which makes this first part straightforward.
Next, turn around to face the row opposite it. This six-washer row corresponds to 001100. Activate the third and fourth working positions, the two adjacent washers in the middle.
The row directly back-to-back with that second row is the third line of the note. Its code, 100001, means the two outer positions should be active. Turn on the first and last working washers in that row.
The next three rows all read 000000. Leave every machine in those sections off. This is where many mistakes happen: a washer that seems unrelated can still be part of a zero row.
The final active washer is in the six-machine row along the back wall closer to the front entrance. The last code is 100000, so activate only its first washer, starting from the left when reading that row.
| Physical area | Pattern | What to do |
|---|---|---|
| Left-side back wall, seven washers | 0001000 | Turn on the middle, fourth washer |
| Facing row of six washers | 001100 | Turn on positions three and four |
| Row behind the facing row | 100001 | Turn on both end washers |
| Following three rows | 000000 | Keep every washer off |
| Back-wall row near entrance | 100000 | Turn on the first washer only |
Do not worry if a position in the code corresponds to a machine marked out of order. Those washers are already fixed in the off state, exactly as the puzzle expects. Only manipulate washers that can actually be switched.
Complete the Pattern and Collect the Rewards
After setting the five required active washers, pause and scan the entire laundromat. Every other working washer must be off. The correct configuration has only these active positions:
- One washer in the seven-machine left-side row.
- Two neighboring washers in the next six-machine row.
- Both end washers in the row behind it.
- One washer in the final row near the entrance.
When the setup is correct, a concealed wall at the back of the laundromat slides open. Go through the newly revealed passage and descend into the hideout area.
The most valuable reward is a Health Upgrade Point, found in a crate within the secret area. This makes the puzzle particularly useful early in a playthrough, when added survivability can make supernatural encounters less punishing.
You can also find lore documents in the room. These include “Visitation and Stay Protocol” and “Do Not Leave The Shelter,” making the hideout worthwhile for players collecting narrative material as well as upgrades.
| Reward | Where to look | Why it matters |
|---|---|---|
| Health Upgrade Point | Loot crate in the hidden section | Improves survivability |
| “Visitation and Stay Protocol” | Secret room documents | Adds story context |
| “Do Not Leave The Shelter” | Secret room documents | Adds story context |
| Secret Hideout progress | Triggered by opening the passage | Helps complete optional content |
If the door does not move, reset your attention to the zero rows. The intended solution is not based on activating every usable washer; it is based on reproducing the entire binary display, including all of its off positions.
A reliable troubleshooting routine is:
- Turn every interactable washer off.
- Start at the seven-washer row by the left-side back wall.
- Apply each binary line in room order.
- Recheck the three all-zero rows before checking the last active washer.
- Wait briefly near the back wall for the hidden passage to react.
Avoid changing machines after the wall opens. Once the hideout is accessible, head inside and collect everything before leaving the laundromat.
FAQ
What is the Control Resonant number puzzle?
The Control Resonant number puzzle is the laundromat Secret Hideout challenge in Central. A note displays binary strings that correspond to rows of washing machines. Turn on the machines represented by 1 and leave all 0 positions off.
What is the laundromat code?
The full washer pattern is:
| Row | Code |
|---|---|
| 1 | 0001000 |
| 2 | 001100 |
| 3 | 100001 |
| 4 | 000000 |
| 5 | 000000 |
| 6 | 000000 |
| 7 | 100000 |
How many washers should be on?
Five working washers should be on in total: one in the first row, two in the second, two in the third, and one in the last row. Broken machines remain off and do not need interaction.
Why will the secret door not open?
Usually, an extra washer is still on in one of the three 000000 rows, or the final row has been read from the wrong end. Turn all working washers off and rebuild the pattern from the seven-machine row near the cork board.
What do you get for solving it?
Opening the laundromat’s hidden room gives you a Health Upgrade Point and collectible documents, along with progress toward finding the game’s optional Secret Hideouts.
