Leaks
Hot Water Tap If the drip is cold water, the water control valve on the cold side of
the mix valve is leaking. Open and clean the cold water valve
If the drip is warm or hot water, the water control valve on the hot
side of the mix valve is leaking. Open and clean the hot water valve
Steam Wand A small amount of water will naturally accumulate in the steam
wand between uses if it is allowed to cool. This is normal for any ma-
chine. Make a habit of purging the steam wand of all accumulated
liquids before and directly aer steaming a pitcher of milk
If the steam wand constantly drips warm water and is warm to the
touch even aer an extended me without use, the valve will re-
quire a new seal. Obtain and install a steam valve rebuild kit from
your dealer, service representave, or the Synesso™factory
Steam and/or water bubbling out from around the steam wand pivot
ball indicates that the steam wand ball o-ring needs to be replaced.
This o-ring is included in a steam valve rebuild kit. Machines pro-
duced before #510 will likely benet from the new Teon o-ring,
which provides an improved seal and wear resistance
If water leaks from the space between the steam wand handle as-
sembly and the side panel, o-rings on the brass pusher rod are worn
and need to be replaced. These o-rings are included in the steam
valve rebuild kit. The pusher rod can be accessed by removing the
side panel and pulling the pusher out from the steam valve
Brew Groups A Leaking diuser indicates the brew valve is not sealing properly.
Open the valve and clean the sealing faces with a so cloth. Inspect
the valve for scale and calcium buildup
If water bypasses the portalter gasket and leaks out around the
portalter when properly engaged and brewing, the portalter gas-
ket will need to be cleaned. Use a so brush and scrub any grounds
from the surface of the gasket. Rinse with hot water. If the issue per-
sists, replace the portalter gasket
General Dirty / brown water under the machine indicates the drain box is
clogged or overloaded. Remove the right side panel and clear any
obstructions in the drain box. Be sure the drain hose has an even,
steady slope toward the floor drain. Kinks, dips, or flat runs will slow
or stop the flow of waste water from the machine drain
A small amount of water may splash between frame panels during a
steam wand purge, or when rinsing the drip pan. The water will then
Clean water under the machine or on top of the electrical box indi-
cates an internal leak. Remove the side panels and fascias unl the
source of the leak is determined. Contact your dealer, service repre-
sentave, or the Synesso™factory for more info on xing your spe-
