Cimex solution does not feed to pads

[Lounge Lizards]

Another possible cause:

The four locating screws at the bottom of the solution rod that opens & closes the solution valve may have come loose.

This can cause the solution valve to become loose.

As you pull the trigger, the entire solution valve is lifted, instead of releasing pressure on the solution line, you are actually lifting the entire solution valve.

Periodical checking & tightening of all screws, etc;  is part of my regular maintenance for my old machine.

Hope the above helps & makes sense if Rick's explanation doesn't fix your problem.
