Shark Error 45 — Side brush motor broken
DIRECT ANSWER
COMMON CAUSES · RANKED
Long-term jam damaging the motor MOST COMMON
A brush that ran jammed for weeks overloads the small motor until the hardware fault trips.
Side brush motor failure
If the brush spins freely by hand but Error 45 returns, the motor or its driver has failed — contact Shark support.
HOW TO FIX IT
Clean the side brush and gear
Power off, lift the brush off its post, strip off wrapped hair, and clean the gear underneath (the full Error 2 routine).
Refit and test
Reattach the brush, confirm it spins freely 360° both ways, and run a short clean.
Contact support if it returns
A clean, free brush that still trips Error 45 points at the motor — quote your model and the code to Shark support.
