•
Periodically the pump will come on by itself to maintain the proper water level in the
boiler. Sometimes the pump will come on when you turn on the machine and
sometimes it may not depending on the water level in the boiler which is normal.
•
The pump (brew) pressure is regulated by the expansion valve. To learn how to set
the pump pressure, please refer to the maintenance section of the owner’s manual.
Water Reservoir (Tank)
•
The water reservoir can be accessed by opening the hinged reservoir door on the
top of the machine. It is recommended that the reservoir be removed prior to filling
to prevent the spilling of water inside the machine which can cause damage to
sensitive electrical components. Should water accidently get spilled inside the
machine then immediately turn the power switch to the off position and unplug the
machine from the electrical outlet. Do not plug the machine back in until it has had
at least 1 full day to dry out. If it does not operate after that time then unplug the
machine and refer to the troubleshooting section of the owner’s manual.
•
The reservoir must be installed properly for the machine to function. The float
inside the reservoir must be on the left side of the machine. Also be sure the
reservoir is seated as far down as possible and the silicone hoses are not pushing
the float down or the PID and heating lights will not turn on.
•
The machine is equipped with a magnetic float in the water reservoir to detect the
water level. When the water level gets low the PID and heating lights will go out and
the pump will no longer function until the reservoir has been refilled.
•
The reservoir should be cleaned at least once a week with mild dish detergent and
rinsed thoroughly before use.
DO NOT PUT IN DISHWASHER!!!
•
Depending on your water quality it may be necessary to periodically sanitize the
reservoir or if you are using hard water and have a mineral build up inside. White
vinegar can be used to sanitize and will also remove the mineral deposits that can
accumulate.
