Parker Lucifer 3-way Solenoid Valve with 230V YB09 coil
Details:
Typically found on the group head of a commercial coffee machine and home machines.
This solenoid valve includes the longer-lasting ruby viton seal pad in the valve- better for hard water areas. The cheaper versions have a rubber pad and don't last as long. Comes with the coil and valve ready assembled.
You may need to replace your solenoid valve and coil if:
No water is coming from the group
Water is constantly dripping from the group or from the solenoid base
Valve burned out - This is rare - more likely that the valve is blocked or worn.
It is not always necessary to replace the whole solenoid, a quick solution is just to replace the valve. See below
Take care when replacing the valve - make sure the holes align with the holes on the group - otherwise no water will come from the group.
How to replace a solenoid valve on a coffee group:
Make sure you have turned off the water connection before you remove these valves, otherwise, water will spurt out of the group.
Remove the 4 hexagonal nuts with an Allen key - make sure you have the correct Allen key otherwise, you may damage the nut.
Insert the Allen key into the hexagonal nut and tap anti-clockwise with a spanner - this will break the seal caused by a mineral build-up.
When replacing make sure that the hole of the solenoid is correctly aligned with the hole in the coffee group, otherwise, you won't get any water from the group. Also make sure the o rings are present on the base of the body, as they can slip off during transport.
If you have to replace it while the machine is still warm - be careful as hot water will pour from the group - better to do it while it cold.
Refit the coil and check the body for leaks.
💡If screws were hard to take off - then you should replace them with new screws, as next time they may not come off if they are damaged. see solenoid screw hex M4X10.
