Hoover steam vac, brushes won't rotate, have cleaned filter by brushes, removed brushes and they rotate okay when off steam vac, tried to ajust level for carpet cleaning and brushes still don't move

There are three things to check when experiencing 'no spin' on the cleaning brushes. 1) Check the small pull out filter screen under the machine. It must stay clean for air to pass to the turbine which powers the brushes. 2) Check that the long shaft on the brush assembly is not broken off. This shaft inserts into the turbine motor and powers the brushes. If you're handy you can replace just the long shaft brush rather than replacing the whole brush assembly. Look for the brush on Ebay 3) If you're handy you can dissemble the machine and inspect the turbine motor which powers the brushes. In all cases the bearings seize in the turbine. You can often free them up and re-lube them to get more service from them or simply replace the turbine assembly. Don't throw your Steam Vac out because the brushes no longer turn...you can fix it!

I took our Hoover in to the Hoover repair shop and got it fixed for under $50.00.  The probelm? The design allows water to get into the bearing and it won't work any more.  The problem solely lies on Hoover.  It is cheaper to get it fixed than purchase a new carpet cleaner even though the problem shouldn't have existed at all.  I am upset with Hoover for not giving owners a free fix on this one.

Check to see if the shaft on the brush block hasn't broken off. Otherwise it is the turbine that drives the brushes and is either clogged up inside or needs to be replaced.
