Beverage Dispense Splatters/Multiple Streams
Issue:
When crafting a Lavit beverage the dispense stream is broken up and several streams
may be present andthe cup may overflow.
Solution:
This situation is usually the result of one of the conditions below.
1.
Verify that the silicone nozzleinside the brewer is present and that itis
firmly attached to the water outlet fittings.
2.
If water is also present in the capsule after the dispense cycle then
recalibrate the mix stream. Recalibrate other streams if
necessary.
3.
Clean the chamber and verify the full rotation of the capsule lifting
mechanism. Remove the capsule tray. Pull the linkage attached to the top
of the chamber towards you. Reach down under the linkage and grasp the
capsule lifting mechanism (solid black plastic with a semi-circle cut out).
Rotate the mechanism forward to a full 90-degree position. Push
mechanism all the way back and repeat 3 times ensuring it moves freely.

“Clean Brewer” Screen Appears
Issue:
Whenusingtheunit,theCleanBrewerscreenappears.
Solution:
There are two reasons why the "Clean Brewer Screen” appears.
1.
The brewer is designed so that after a beverage is brewed the capsulelifting
mechanism returns fully to the “Home” position.A Hall Sensor is installed in
the unit to verify that the mechanism has returned Home. If themechanism
does not return to Home then the Clean Brewer screen is displayed. The
normal cause for this to occur is that there has been a beverage build up in
the chamber preventing the mechanism to fully return to Home. Follow the
cleaning instructions to clean the brewer.

ensure the two locks are secure. If that does not resolve the issue,follow the
ribbon lead going to the back bottom of the brewer. Locate the secondary

“Close Brewer Lid” Error when Brewer Closed
Issue:
The touchscreen displays a "Close Brewer" message but the brewer lid is in
the closed position.
Solution:
The close brewer message will bedisplayed when thebrewer lid is closed
underthreecircumstances:
1.
Ensure that the brewer magnet is present. Open the brewer and locatethe
magnet on the right hand outside wall on the brewer lid. It will be a small
1/4" metallic disc pressed into the external side wall. If the magnet is not
present insert a replacement.
2.
The ribbon connector is loose on the main PCB. Remove the top panel
cover. Pull back the plastic cover over the main PCB located on the front
right of the unit. Verify that the black ribbon connector on the far left of
the PCB is firmly attached and the two locks are in place. Disconnect and
reconnect as necessary.
3.
If neither of the above clear the error check the Hall Sensor connection to
the ribbon cable. With the top panel removed locate the magnet and Hall
Sensor attached to the external wall of the brewer 1
st
ensure the magnet
is in place. If not replace it. Then make sure the sensor lead is properly
connected to the main ribbon cable. If it is and the error remains then
