What to do if I get error 25 (Abnormal input from bottom sensor in motion) on my EZ1 instrument?

Check that the recommended silicone grease (cat. no. 9239334) is used to lubricate the tip adapters on the plunger unit.

Make sure the tip adapters do not have excess grease. Wipe off any excess. Turn off the instrument and perform a test run to see if the error persists.

If correct grease was used and excess grease is not an issue, please contact QIAGEN Technical Service to obtain teaching instructions and teaching data sheet for your instrument.
