Dreame Robot Vacuum Error Codes & Fixes

Last updated: May 19, 2026 | 8 min read

Key Takeaway

Dreame robots report errors through the Dreamehome app and on-robot voice prompts (e.g. “Error 7, please check”). Most errors fall into four families: sensor blockage, brush stall, wheel stuck, and dock connection — and the fix is almost always cleaning, clearing wrapped hair, or re-seating a part. Code numbers and exact wording can shift across firmware versions and product lines; if the message in your app differs from what's listed below, the underlying cause is usually the same family of issue, so apply the matching fix.

Navigation & Sensor Errors (1–10)
Brush & Wheel Errors (11–20)
Mop & Water Errors (21–30)
Dock & Charging Errors (31–40)
WiFi / App / Update Issues
Factory Reset Procedure

Navigation & Sensor Errors (1–10)

Code	Meaning	Fix
1	LDS (laser) sensor blocked or stuck	Clear hair or dust from the LDS tower. Spin the tower gently by hand to check rotation.
2	Bumper stuck	Press the front bumper and listen for the click. Tap it to free debris.
3	Cliff sensor blocked or dirty	Wipe the four downward-facing cliff sensors with a dry microfiber cloth.
4	Wall sensor failure	Wipe the right-front IR sensor. If error persists, contact support — sensor may be defective.
5	Robot on a cliff or steep slope	Move the robot to flat ground. If on flat ground, see error 3.
6	Robot trapped or blocked	Remove obstacle. If under low furniture, raise the robot manually.
7	Camera obscured	Clean the front camera lens. Verify no plastic film remaining from packaging.
8	Top sensor obscured	Wipe the upward-facing optical flow sensor.
9	Robot lifted during operation	Place the robot on the floor and press Start.
10	Localization lost	Carry the robot to its dock and start a new mapping cycle.

Brush & Wheel Errors (11–20)

Code	Meaning	Fix
11	Main brush stuck	Remove brush, clear hair from bearings. Verify brush snaps back into housing.
12	Side brush stuck	Unscrew side brush, clear hair from axle, reattach. Replace if bristles permanently bent.
13	Right wheel jammed	Lift robot, spin right wheel by hand. Remove wrapped hair or thread.
14	Left wheel jammed	Same as 13 for left wheel.
15	Wheel motor over-current	Check both wheels for debris. If repeated on flat ground, wheel motor may need service.
16	Suction motor over-current	Empty bin, clean filter, check for blockage in suction channel.
17	Filter clogged or missing	Re-seat HEPA filter. If clean, replace it.
18	Bin not detected	Re-seat dustbin. Check magnetic contacts are clean.
19	Dust bin full	Empty bin manually. Self-empty bases should handle this automatically; if not, see code 31.
20	Brush motor overheat	Power off for 15 minutes. Check for tangle that's causing extra friction.

Mop & Water Errors (21–30)

Code	Meaning	Fix
21	Water tank empty (clean)	Refill clean water tank.
22	Wastewater tank full	Empty wastewater tank on dock.
23	Mop module not detected	Re-seat mop module. Check magnetic contacts.
24	Mop pad stuck or motor stalled	Remove mop pads, check spindle for obstruction.
25	Water pump fault	Run dock self-clean cycle to clear airlock. Persistent fault = service.
26	Mop lift mechanism stuck	Carefully wiggle mop arm. Common after debris jam in lift gear.
27	Water tank not detected	Re-seat both water tanks on the dock.
28	Detergent low	Refill auto-dispense detergent tank if equipped.
29	Hot water temperature out of range	Dock heating element fault. Power-cycle the dock.
30	Mop pad wash incomplete	Run dock self-clean manually. Verify drain hose is not pinched.

Dock & Charging Errors (31–40)

Code	Meaning	Fix
31	Self-empty dust bag full	Replace dock dust bag.
32	Self-empty motor over-current	Check for blockage in dock suction channel. Common cause: hair clog.
33	Charging contacts dirty	Wipe both robot and dock contacts with dry cloth.
34	Battery temperature out of range	Wait 30 min for battery to reach 10–40°C ambient.
35	Battery fault	Charge for 12 hours. If unresolved, replace battery.
36	Dock not detected	Power-cycle dock. Check power adapter.
37	IR docking signal lost	Clean IR receiver on robot front. Move dock to a clearer location.
38	Robot can't find dock	Carry to dock manually. Start a new mapping run.
39	Dock water reservoir low	Refill clean water tank.
40	Dock waste reservoir full	Empty wastewater tank.

WiFi / App / Update Issues

App can't find robot during setup: Confirm 2.4 GHz network (not 5 GHz). Disable WPA3-only mode on the router. Place phone and robot within 2 m of each other during setup.
“Device offline”: Robot has lost WiFi. Press the power button briefly to confirm power. Hard-reset WiFi: hold Spot + Home buttons for 5 seconds.
Firmware update fails: Confirm robot is on the dock with at least 50% battery. Update can take 10–30 minutes; don't move the robot during.
App stuck on “cleaning” after dock: Force quit and re-open Dreamehome. State will sync.

Factory Reset Procedure

Resets all settings, maps, and WiFi credentials. Use as last resort.

Power on the robot (press top button until light comes on)
Hold Home + Spot (the two side buttons) simultaneously for 5 seconds
Wait for voice prompt “Restoring factory settings”
Robot reboots and is now in pairing mode
Re-add the device in Dreamehome

Saved maps and no-go zones are lost on reset. Export the map first if available in your firmware version.
