Hottop KN8828B - Dumping beans immediately

My Hottop KN 8828B from 2009, has been dumping the beans about a minute after loading. I've followed the suggestions from Hottop to disconnect the fan, to no avail. Has anyone experienced this problem and if so how did you repair the machine? New control board? TIA

Olympia Cremina SL Group Maintenance

This design looks similar to one for the Ponte Vecchio machines. I would suggest putting a rubber tip of some sort on the threaded rod where it contacts the piston. Do you plan to remove the grouphead to perform the service?

Olympia Cremina SL - stronger spring

I like that idea, but wonder if the lever will be too hard to press down? It requires a fair amount of force as it is now. The SL has been a disappointment for it's weak spring
