Ecovacs Deebot Error 100 — Charging Fault Fix Guide

What Does This Error Mean?

Error 100 means the robot can't get a charge — either it's not making contact with the dock, or the dock isn't delivering power.
Wipe the metal contacts on both the robot and the dock with a dry cloth.
Make sure the dock is plugged into a working outlet (no power strip — those can flicker).
Re-park the robot manually and watch for the charging light.
This is usually a contacts issue, not a battery issue.

Common Causes

Dust or grime on the dock contacts
Robot contacts oxidized or coated
Dock power adapter unplugged or outlet dead
Robot pushed dock out of position — contacts no longer aligned
Battery degraded after years of use (won't accept charge)

How to Fix It

Wipe the metal contacts on the dock.

Look at the front-bottom of the dock.
You'll see two metal strips or pads — those are the charging contacts.
Wipe them with a dry microfiber cloth.
If they look dull or have a film, use a pencil eraser to gently clean them.
Wipe the contacts on the robot.

Flip the robot over and look near the back edge.
You'll see two matching metal strips that line up with the dock contacts.
Wipe them dry — they often pick up dust as the robot drives around.
Check the dock's power supply.

Follow the cable from the dock to the wall.
Make sure the outlet works (test with a phone charger).
The dock should have a small light on it indicating power.
If no light, the issue is the adapter or outlet.
Manually park the robot.

Carry the robot to the dock.
Set it down so the contacts under it line up with the contacts on the dock.
Push it lightly forward.
You should hear a beep and the charging indicator should come on within a few seconds.
Test the dock with a different outlet.

Move the dock to a different outlet — preferably a wall outlet, not a power strip.
Some power strips have surge protectors that interfere with the dock's charging signal.
If it works on a different outlet, the original outlet had a wiring issue.

Frequently Asked Questions

Could the battery be the problem?

After 2–3 years of daily use, robot vacuum batteries lose capacity and eventually refuse to charge.
If contacts are clean, the dock has power, and the robot still won't charge, the battery is at end of life.
Replacement batteries are user-serviceable on most Deebot models — typically 2 screws.

Why does the dock keep getting pushed out of place?

If you have a thick rug near the dock, the robot can shove the dock backwards every time it docks.
The fix is mounting the dock against a wall with the supplied tape strips, or moving it to a hard-floor area where the robot can dock without pushing.
