  2. Using a flathead scewdriver, remove diffuser screw and diffuser screen from brew group.  With an O-Ring pick, locate the slot in the brew group and use the pick to pry out the old portafilter gasket.  The arrows demonstrate where to find the slots. It may be necessary to remove bayonet ring if gasket is difficult to remove or a pick is unavailable to use.

  3. Ensure that espresso module is displaying the correct pump pressure. Ensure that module is putting out an accurate volume by switching profile to lineaesque.  Start by tapping the profiles icon in the settings screen. Use the encoder knob or press "lineaesque" then save and exit.  Brew into a vessel and measure the output volume.  Should be between 500-650 grams or ml.

  4. Inspect module inside and out for leaks that may occur at pump, manifold, boilers, pressure transmitter, 3-way valve, flowmeter inlet and outlet ports and external fittings. Inspect tap and drain hosing to ensure there is a proper slope with no dips/valleys that could potentially affect volumetrics.  Look for proper drainage after shot extraction.

    • Remove tap handle. Reference this video for proper handle removal.

    • Be conscious of microswitches while removing handle.

  7. Clean handle and using "wet" bike lubricant, lubricate slots and bearing on both sides. Reinsert handle and check microswitch functionality by actuating the lever in both the middle and down positions.  If the module is set for manual and automatic dispense mode, the middle position should display the word "manual". After confirming that the middle position engages "manual" on the screen, pull the handle the rest of the way down to "auto" mode and listen for the pump to activate.
