the drip pan. The water will then drip onto the countertop or frame of the machine. This is normal.

• Clean water under the machine indicates and internal leak. Have a technician perform further diagnos-

cs.

• In the case of a large leak in which water is collecng in the machine frame or pooling signicantly below

the machine, power down and unplug the machine and shut o the main water supply unl a technician

has repaired the leak.

Vacuum Breaker:

• When the machine is heang from cool and begins to build pressure from zero, it is normal for the vacu-

um breaker to spuer unl the steam tank is near full pressure.

• If spuering occurs when the steam tank is near or at the set pressure, have a technician replace the vac-

uum breaker.

General Issues

Beeping Machine:

• Low level alarm probe is not grounding out. Power cycle the machine. Ensure the tank is lling. Check for

adequate water ow to the machine. Have a technician perform further diagnoscs.

Portalter Stopping Point is O

• Under normal circumstances, when the portalters are fully engaged the handle will face the barista. If

the portalter stopping point is occurring before this point (handle points to the le), check that the

standard size 8.5 mm gaskets are being used and that the gasket is seated fully around the diuser block.

• If the portalter stopping point is occurring aer the normal point (handle points to the right), inspect

the “ears” of the portalter for wear. If brass is showing on the ears, try using the taller 9mm gaskets.

Alternately, you can replace the portalter head.

Pump/Motor is Making an Unusual Sound:

• Make sure the water to the pump is fully on. Check the lters for clogs, change if needed. Check the wa-

ter lines for kinks.

• Pump may be worn and in need of replacement.

High-Pitched Whistling Noise When Groups are Acve:

• Water is leaking out from the brew system. Check for VMUF0# error. Have a technician inspect the ex-

pansion valve and brew valve discharge for unusual ow.
