Question about Zassenhaus Knee Mill Hand Crank 156 Manual Burr Grinder
Looks like a pump problem. If you descale regularly, then the pump might be getting worn out. If you don't descale regularly, run some 1:1 water and vinegar then let it sit without rinsing. But don't run the pump for too long, just a couple of minutes, then let the water with vinegar sit for 4-5 hours, then run the descaling mix again for a couple of minutes, etc., repeating as long as necessary until the unit runs clean.
If you run the pump for too long at a time, this will burn the pump and you'll have to fork 40$ to 60$ for a new one.
If the output doesn't get better with descaling, then the pump is worn and you'll need a new one. It's not that hard to change: just fasten two clips on the tubing et voil?.
It's good to check the O-rings for the needle that controls the debit and change any that have become hard or are flat on the side instead of round. Expresso machine repair shops will routinely charge ludicrous amounts (over 5$) for what is actually a generic 6mm O-ring. It's up to you, but it is possible to find food-grade O-rings that can bear the temperature of boiling water (which is not that high a temperature) for a much better price than that.

Use a small abount of your ladyfriwenjds nail varnish on the adjustment nut or screw to prevent vibration from lossening it.
