CAUSE
Because of space limitations, the waste tubing is not routed correctly.
The position of the waste tubing from the vent valve into the drip tray was a causing a leak through the side of the tray.
The position of the waste tubing was higher than the detector drip tray, gravity caused solvent waste to flow back to the drip tray
FIX or WORKAROUND
Route the tubing so that, instead of coming straight off the instrument, it faces down so that gravity can assist solvent flow.
Ensure the tray is correctly aligned with no gaps in the side and that the waste tubings from the vent valve are directed into the drainage cup and not the side of the drip tray.
