Jobo CPP3 lift outlet dripping issue

[sunhouwang]

Hi, All.
The Jobo CPP3 machine was new purchased years before, which gave me a lot fun of development.
Recently the outlet of lift would be dripping when pouring chemicals, especially at the end stage of the pouring action.
I duplicate the actions and find the issue would be come out when the liquid flow is slow, and will hardly occur if the liquid flow is fast.
Does any friend have experience to point out the root cause or fix it?

Instructions for Jobo CPP lift says: When pouring liquids into the JOBO Lift funnel, pour steadily so liquid does not overflow the built-in funnel. Pouring too rapidly can cause some liquid to flow out the drain, or leak into the motor unit, causing damage.
While my issue occurs when pouring liquid is not very fast.

Pouring too fast and possibly overfilling the tank. The liquid needs time to flow through the small tube that fills the tank.

Your finding is the typical behaviour of all Jobo Lifts, @sunhouwang. As mentioned before, you need to pour not too fast to avoid overflow.

My issue is pouring slowly will cause the outlet dripping.
As in each stage, the last remaining chemicals in the bottles will be poured slowly, then the issue would come out sometimes.

I know and follow the instruction, not pour too fast.
But the issue will happen when pouring liquid flow is slow, please check the left video.

Does it leak if your pour like in the left video but closer to the tank?

I find that the issue will come out depends on the liquid flow, lower speed is more easier to leak or drip, not relevant to the distance with the tank.
