SHARK·FAULT ERR 31 CRITICAL

Shark Error 31 — Suction motor broken

Severity: Critical — the suction motor itself is failing — cleaning first, then a service case PowerDetect
Last verified: 2026-07-06 Tools: none Time: ~10 min Difficulty: easy

DIRECT ANSWER

Error 31 means the suction motor reports a hardware fault. Shark's error list groups it with Error 3 and prescribes the same first aid: clear dust cup, filters and brushroll, then contact support if it returns.

COMMON CAUSES · RANKED

1

Severe airflow blockage overworking the motor MOST COMMON

A fully choked filter or duct forces the motor far past its normal load before the fault trips.

2

Suction motor wear or failure

Unlike Error 3, the "broken" variant often means the motor itself — persistent errors after cleaning are a support case.

HOW TO FIX IT

No battery or electrical work involved in this fix.

Run the full Error 3 cleaning routine

Power off, empty the dust cup, clean the filters and mesh screen, and clear the brushroll, end cap and compartment.

Test on a short mission

Power on and run a few minutes of vacuuming to see whether the fault returns.

Contact Shark support

An Error 31 that survives a full clean means the motor needs service — quote your model and the code.

Tap the filter clean between missions and let it dry fully after washing; a clogged filter is the top trigger for suction Errors 3 and 31.
