ALL SERVICE PERFORMED ON THIS UNIT MUST BE DONE BY A QUALIFIED SERVICE TECHINICAN.
PROBLEM
Water in heating tank does not heat up at all.
SOLUTION
1 . Check the power supply. Make sure the power cord is properly connected and 120
volts are flowing to the outlet.
2. Check that the thermostat is turned on. Turn the stem clockwise until it stops.
3. Check the reset thermostat to see if the red button has popped out. There should be
water in the heating tank. Fill with water then push in the red reset button.
4. Check for voltage at the heating element terminals. Voltmeter should read 110V to
120V. If there is no voltage reading at these terminals, the thermostat may be
defective and not allowing current to flow to the element (a common occurrence
if the unit has been allowed to run dry). Replace thermostat.
5 . If the volt meter reads 110V to 120V at the heating element terminals, the
thermostat is okay. Remove wires from heating element terminals and test them for
continuity. You may use an ammeter if available. Clamp it on the black wire, from
thermostat to heating element. This will indicate how much current, if any is flowing
through the wire. If no continuity or low amp reading is indicated (under 15 amps),
replace the heating element.

PROBLEM
Poor spray pattern over coffee grounds. Coffee is not evenly saturated.
SOLUTION
1 . Check all the silicone water tubing for lime buildup and clean out.
2 . Sometimes the silicone tubing gets kinked. Make sure the tubes are not too long where
they might fold; or too short where they could be pinched off when the unit is closed up.
3 . Look for an obstruction in the sprayhead fitting and clean if necessary.
4 . The plastic sprayhead might be deformed or in need of cleaning. It is very difficult to tell
if the tiny point in the center of the sprayhead is worn or is just slightly off-center.
Replace the plastic sprayhead.
PROBLEM
Brewed coffee cools down too fast.
SOLUTION
1 . Check warmer switch (item #5) by reading voltage at the terminals of warmer element. If
there is no voltage reading when switch is pressed, then switch is faulty. Replace switch.
2 . If there is voltage at the terminals of the warmer element (item #22) but the element still
does not heat up, test element for continuity. If it is open (burned out), replace element.
