TROUBLESHOOTING
hot and cold water mix valves, the main board. Electrical troubleshoong required.
• Signicant scale buildup is inhibing ow. Inspect hot water and cold water mix valves.
Only Cold Water Flows when Switch is On:
• Turn the mix valve clockwise unl it stops. This will cut o all cold water ow. If no water ows with the
mix valve o, the hot water valve has failed.
• Check the steam pressure gauge reads 1.1 bar or higher. Hot water will not ow without pressure from
the tank.
Only Hot Water Flows when Switch is On:
• Check that the cold water mix valve is not fully closed. A fully closed mix valve will only allow steaming
water out to the hot water tap. Turn counter-clockwise to open and allow cold water to mix with the hot
water.
• Turn the cold water mix valve a full turn and a half counter-clockwise. If the water at the tap is sll steam-
ing/spuering, the cold water valve has failed.
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. Replace valve if necessary.
• 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. Replace valve if necessary.
Steam Wand:
• See troubleshoong related to steam wand starng on page 76
Brew Groups:
• A leaking diuser 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 leaks out around the sides of the portalter when properly engaged and brewing, the portalter
gasket should be cleaned. If the leak connues once the gasket is clean, the gasket should be replaced.
Other Leaks:
• Dirty / brown water under the machine indicates the drain box is clogged or overloaded. Remove the
right side panel and clear any obstrucons in the drain box. Be sure the drain hose has an even, steady
slope towards the oor drain. Kinks, dips, or at runs will slow or stop the ow 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 drip onto the countertop or frame of the machine. This is normal.
• Clean water under the machine or on top of the electrical box indicates and internal leak. Remove the
machine panels and inspect for the source of the leak. Contact your dealer, service representave or
Synesso™ Technical Support for further troubleshoong.
