We've got an ultimate 3000 system that hadn't been used for a few months. When we turned it back on everything seemed OK except the rear seal wash. The peristaltic pump that pumps the wash solution doesn't turn at all (it used to start up as soon as you switch the instrument on).
We've tried manually purging the lines with a syringe and switching the rear seal wash off and back on in Chromeleon. Anyone got any ideas of other things to try?
Does anyone know if we're likely to damage the system if we run the pump without the rear seal wash? We don't use any buffers so there shouldn't be any salts getting deposited on the seals (my understanding is that the main purpose of the rear seal wash is to remove these kind of things).
Thanks.
