The CEME part number has changed from V799VN15PAIF to V799VN15PMCAIF to constant CEME revisions of the product
The ambient temperature has been noted to be well within the 80c limit due to positioning of the valve in the machine, down from 120c as the old part number was once years ago.
This is a 2 way valve that operates in one direction, make sure you observe the port numbers 1&2 from your existing pump.
If the valve is failing then reverse the ports. This would be a user error and must be right.
This is the CEME plastic pump not the OLAB metal version.
