TROUBLESHOOTING GUIDE
Hot Water Tap
No Water Flows When the Switch is Pressed:
• Have a technician perform further diagnoscs.
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
steaming/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. 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 troubleshoong related to steam wand starng on page 38.
Brew Groups:
• A leaking diuser indicates the brew valve is not sealing properly. Have a technician inspect the valve.
• 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. 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
