Narwal error codes and what to try first
66 code entries1001–1060: battery, brushes, wheels, sensors and navigation
| Code | What it means | First thing to try | Full guide |
|---|---|---|---|
| 1001 / 1003 / 1004 | Battery fault | Restart the robot. If the code comes back, contact Narwal support. | — |
| 1005 / 1006 | Battery too hot (1005) or too cold (1006) | The robot works best between 5 °C and 40 °C (41–104 °F). Move a base station that sits on a balcony or in direct sun indoors, let the robot rest for 30 minutes, then retry. Remap afterwards if you moved the base. | — |
| 1007 / 1008 | Roller brush fault | Take out the roller brush, clear wrapped hair, refit it and restart the robot. | — |
| 1009 / 1010 | Mop pad or mopping-module fault | Freo Pro, Freo X Ultra and Freo Z Ultra: clean the mopping module and restart. Freo Z10 and Z10 Ultra: remove the mopping module and check its sealing plate for damage first. | Open guide →Narwal Freo Z Ultra guide |
| 1011 | Localization error: the robot cannot match where it is to the saved map | Remap if the base station was moved, and check that a temporary map is not active. | Open guide →Narwal Freo Z Ultra guide |
| 1012 | Robot trapped | Clear obstacles, move the robot to open floor and restart the task. Check that the bumper springs back and the LiDAR turns without red blinking. | Open guide →Narwal Freo Z Ultra guide |
| 1013 | Robot entered a no-go zone | Move it out of the zone and restart. If it keeps happening, send Narwal a screenshot of the map with its zones and where the robot stopped. | Open guide →Narwal Freo Z Ultra guide |
| 1014 / 1015 / 1016 | Drive wheel fault | Spin both rear wheels by hand. Clear debris from a wheel that turns unevenly, then restart. | — |
| 1017 | Cliff (anti-drop) sensor triggered | Wipe the cliff sensors, set the robot on flat, open floor and restart the job. | — |
| 1018 / 1019 | System malfunction | Power the robot off and back on. If the code returns, contact Narwal support. | — |

| 1026 | Robot lost its connection to the base | A short drop at long range is normal. If it doesn't recover, unplug the base until its screen goes dark, restart the robot and dock it again. | — |
| 1027 | Base station malfunction | Unplug the base station to restart it. | — |
| 1028 / 1029 | Mopping paused: poor contact between robot and base | Clean the charging contacts on both, reseat the robot so the contacts line up, then restart. Oxidized or damaged contacts need Narwal support. | — |
| 1030–1038 | Mopping-module fault | Check the mopping module is fitted correctly and restart. If it returns, tell Narwal which task was running. | — |
| 1039 / 1040 | Mop-pad drying interrupted | Narwal asks for a short video of the problem, so contact support. | Open guide →Narwal Freo Z Ultra guide |

3000–3010: automatic water-change module
These codes only appear on base stations connected to a water supply and drain. Narwal labels all of them as an automatic water-change module fault; the middle column says what Narwal's fix points to.
| Code | What it means | First thing to try | Full guide |
|---|---|---|---|
| 3000 / 3005 | Water-change fault — Narwal's fix points to the water supply | Update the firmware, confirm the supply valve is open, check the pipes for leaks or kinks, reseat the top cover and hold the water-drop button for 10 seconds to run the self-test. | — |
| 3001 / 3006 | Water-change fault — Narwal's fix points to the drain line | Check the drain pipe for sharp bends. If there are none, Narwal treats it as a blockage in the pipe: contact support. | — |
| 3002 / 3008 | Water-change fault — Narwal's fix points to water left inside the base | Remove the cleaning module and base tray, dry the inside of the base, wipe the black conductive silicone in the base slot, let everything dry, then restart after at least 10 seconds off. | — |
| 3003 / 3009 / 3010 | Water-change fault — Narwal's fix points to how the unit is seated | Make sure the unit sits flush with the base, then switch the robot and base off for at least two minutes. | — |

This table summarizes Narwal's robot-vacuum index, not its separate handheld vacuum-mop codes. Availability and first checks can differ by model; for example, Narwal gives different 1009 / 1010 instructions for Freo Z10 than for Freo Pro, Freo X Ultra, and Freo Z Ultra. Check the model-specific note and linked diagnostic before removing a module or changing a map.

19 guidesNarwal troubleshooting questions
What does Narwal error 1019 mean?
Narwal groups 1018 and 1019 as a system malfunction. The fix Narwal gives is a full restart: power the robot off, then back on. If the code comes back, contact Narwal support with the code and the robot's serial number.
How do I restart a Narwal robot and base station properly?
Power the robot off and back on. For the base station, unplug it and wait until its screen goes completely dark before plugging it back in. If the robot's indicator is flashing red, Narwal's forced restart is to hold the start button for 2 seconds, wait about 30 seconds for the lights to go out, then press start again.
Why does my Narwal say the base station can't be found?
That is 1022 or 1023. If it happens on or near the base, check the base has power and that the roller brush, wheels and cleaning tray are fitted properly. If it happens across the room, clean the reflector stickers on the base. If you moved the base, remap.
Do I need to remap after moving the Narwal base station?
Yes. Narwal notes that moving the base station requires a new map, and several codes, including 1011 localization errors and 1022 / 1023, can follow a base that was moved without remapping.
What does Narwal error 1140 mean?
Narwal says 1140 usually indicates a non-original battery, which it treats as a safety risk. Stop using the battery and contact Narwal about a factory replacement.
What if my Narwal code is not listed here?
Confirm the exact model and capture the full code in the Freo app; do not choose a fix based on a nearby code. Check that model's Product Help page or send Narwal support the code, robot serial number, app screenshot, and a short video if the fault is visible.
