La San Marco Group One (Left) Dosing Circuit Complete

Complete Left-Side Dosing Circuit Assembly for La San Marco

For one-group models, as well as the left side of two, three, and four group 85-16M series machines. On multi-group machines this board is always the first one, positioned on the far left. The board inside is code 108286, with five small diodes along the top numbered R1-R5.

COMPATIBILITY

• Fits: La San Marco one-group models; left side of two, three, and four group 85-16M series machines
• Includes: rear cover screws, rear cover, moisture seal, PCB mounting screws, printed circuit board (SM_267, code 108286), front membrane support, and adhesive membrane sticker

INSTALLATION

Assembly required, this is a multi-step technician job: flip the membrane support face-down, seat the PCB in the two center holes using the shorter self-tapping screws (the outer holes are for the rear cover), gently align the LEDs with the support's window openings, fit the moisture seal and ribbon cable, secure the rear cover, and apply the membrane sticker last.

This part ships as a final-sale special order electrical item, see our return policy for details, or email info@espressoparts.com with questions.

PRO TIPS

• Get the screw placement right the first time: the two shorter screws go in the center holes to hold the PCB, while the two longer screws are for the rear cover, mixing them up strips the self-tapping threads.
• The membrane sticker goes on dead last, after the ribbon cable and rear cover are seated, apply it too early and you risk trapping air bubbles or misaligning the buttons with the LEDs underneath.
