REPAIRS
THERMOSTAT ADJUSTMENTS:
NOTE:
The thermostat is behind the lower front panel. If water temperature is less than 197 degrees F
(92 degrees C) slowly turn thermostat knob clockwise until ready light goes out. When temperature of water
approaches 197 degrees to 203 degrees F (92 degrees to 95 degrees C) slowly turn thermostat knob counter-
clockwise until the green ready light comes on. If water temperature cannot be increased when thermostat knob is
turned fully clockwise, then proceed as follows:
Pull off knob. Place a small screwdriver into the center of thermostat shaft. While observing green ready light and
temperature on thermometer, hold shaft and turn small adjustment screw in center counter-clockwise until green
ready light goes out.When temperature of water approaches 197 degrees - 203 degrees F (92 degrees - 95 degrees
C), slowly turn screw clockwise until ready light comes on. Turning screw clockwise lowers temperature;
counter-clockwise raises it. After adjusting center screw, place nail polish or glyptol on screw to set in position.
NOTE: As a final check, measure water temperature at Spray Head . Temperature should be 197 degrees to
203 degrees F (92 degrees to 95 degrees C).
PROBLEMS WITH WARMER ELEMENTS & SWITCHES :
If warmer plate fails to heat, first check power source and then check if light on warmer switch is lit when in the
“ON” position. If warmer switch is lit, replace warmer plate by unplugging brewer, removing the two hold down
screws on plate and withdrawing warmer plate from brewer. Replace the new warmer plate. If warmer switch
does not light, replace it. To remove switch press each tab behind front plate of brewer down with screwdriver in
turn. As each tab is pressed, pop that corner of warmer switch out of the front of brewer. New switch snaps in
from the front.
IF WATER FAILS TO HEAT:
1. If Red power switch and warmer switches do not light, check heater switch in the back, toggle should be in the
up position . Check power supply outlet, replace fuse or reset circuit breaker if necessary. If power is good, check
rear heater switch for continuity and replace if switch stays open.
2. If water still fails to heat, disconnect line cord and check out tank heater, thermostat and high temperature
safety shutoff. Replace needed parts.
REPLACING HI-LIMIT SWITCH, THERMOSTAT, AND TANK HEATER
Unplug power cord, and remove top cover and lower front cover.
HI-LIMIT SWITCH Disconnect the (2) push-on leads, and pull out hi-limit. Replace switch
THERMOSTAT
Loosen (2) screws securing thermostat to housing. Disconnect the push-on leads and
remove thermostat. Replace with new one in reverse order. When installing new control, do not overtighten small
packing nut on compression fitting.
TANK HEATER
Remove tank top, (4) hex nuts and washers. Disconnect push-on leads. Replace in reverse
order. Remove the lower panel and loosen the (2) screws holding thermostat in place.Slide thermostat out of
bracket and remove wires. Remove top cover and pull out Capillary Tank fitting from silicone grommet.
