Rinse pump:

1. Liquid flows back into the rinse container.
   • Replace the rinse pump tube.
2. At the start of the rinse sequence the first pipette is not washed.
   • Replace the rinse pump tube, see Peristaltic pump tube replacement (WI-162 Peristaltic pump tube replacements).

Saline pump:

1. Liquid flowing back to the saline container.
   • Replace the saline pump tube.
2. Needle is not washed sufficiently.
   • Replace the saline pump tube, see Peristaltic pump tube replacement (WI-162 Peristaltic pump tube replacements).

Note:
The wider bore tube is for the rinse pump.
The narrower bore tube is for the saline pump.
