Work with the FC 5 switched off and disconnected. Lay the rollers in their original left and right positions and match the colour marks before pressing them into their holders; swapping the sides can prevent the fittings from seating even when both rollers look identical. After cleaning, Kärcher’s guidance also keeps the rollers wet for use and allows them to air-dry afterwards. Refit each roller without forcing the drive and check that both are level before one short test.
If they now rotate and remain seated, the issue was placement rather than a failed internal part. Stop if a holder is cracked, a drive end is deformed, a roller repeatedly releases or the motor turns without driving it. Do not use lubricant or tools to force the colour-coded fittings, and do not apply the fabric-softener advice from a separate streaking symptom to this seating problem.
