ROOMBA·FAULT CHG 5 CRITICAL

Roomba Charging Error 5 — No charging current

Severity: Critical — battery drains dead unless the charging chain is fixed 600eijs
Last verified: 2026-07-05 Tools: melamine foam or a soft cloth Time: ~15 min Difficulty: easy

DIRECT ANSWER

Charging error 5 means charging current isn't reaching the robot. Work the chain — wall outlet, power cord, dock contacts, robot contacts, battery. Dirty contacts cause most cases; a failing dock or battery the rest.

COMMON CAUSES · RANKED

1

Grimy charging contacts MOST COMMON

Dust and oxide on the metal strips block current between dock and robot.

2

Dock without power

A loose power cord or a dead outlet leaves the dock dark and the robot uncharged.

3

Aftermarket or failing battery UNCOMMON

A worn or clone pack can refuse the charge current even when everything else works.

4

Faulty dock electronics UNCOMMON

If a known-good robot won't charge on this dock but charges elsewhere, the dock is the problem.

HOW TO FIX IT

SAFETY · READ THIS FIRST

Unplug the charging dock and power off the robot before wiping any charging contacts.

Unplug and clean every contact

With the dock unplugged, wipe the metal contacts on dock and robot with lightly dampened melamine foam. Dry before reconnecting.

Verify dock power

Plug the dock in, confirm its indicator lights, and try a different outlet if it stays dark.

Reseat the battery

Power off, remove the pack for ten seconds, reinstall, and dock the robot again.

Isolate dock vs battery

Persistent error with clean contacts means either the battery or dock has failed — swap whichever you can test first.
