Normal Operation, Continued
Water Reservoir
• 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. Fill the reservoir with white vinegar and then let it sit for an hour and then
rinse and clean the reservoir thoroughly. If the reservoir still has a vinegar taste or
odor you can mix some baking soda and water in the reservoir to remove the taste
and odor and then wash it with a mild dish detergent and rinse thoroughly.
