TROUBLESHOOTING GUIDE
Hot Water Tap
No Water Flows When the Switch is Pressed:
• Have a technician perform further diagnoscs.
Only Cold Water Flows when Switch is On:
• Turn the mix valve clockwise unl 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 sll
steaming/spuering, 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. Have a techni-
cian replace the valve.
• If the drip is warm or hot water, the water control valve on the hot side of the mix valve is leaking. Have a
technician replace the valve.
Steam Wand:
• See troubleshoong related to steam wand starng on page 38.
Brew Groups:
• A leaking diuser indicates the brew valve is not sealing properly. Have a technician inspect the valve.
• If water leaks out around the sides of the portalter when properly engaged and brewing, the portalter
gasket should be cleaned. If the leak connues 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. 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
