**SERVICE INSTRUCTIONS** and **TROUBLE SHOOTING GUIDE**
CAUTION: DISCONNECT POWER BEFORE ATTEMPTING ANY ELECTRICAL REPAIRS
Note: The thermostat adjustment knob (Item 15) is located in back of top box. If water temperature is less than 197°F (92°C) slowly tum thermostat knob clockwise
until ready light goes out. When temperature of water approaches 197° to 203°F (92° to 95°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:
Remove Bracket and 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°-203°F (92°-
95°C), slowly turn screw clockwise until ready light comes on. Turning screw clockwise lowers temperature; counter-clockwise raises ~. After adjusting center screw,
place nail polish or glyptol on screw to set in pos~ion.
Note: As a final check, measure water temperature at Spray Head (25, Fig 3). Temperature should be 197° to 203°F (92° to 95°C).
TIMER ~DJUSTMENTS (Automatic Models BT2A, BT3A)
Note: Timer adjustment knob is located in back of top box. To increase volume of water, turn knob of timer clockwise. To decrease, turn knob counter-
clockwise. Turn knob by small increments.
Note: Timer must go through a complete cycle before another adjustment can be made. Timer cannot be adjusted once it has been initiated.
PROBLEMS WITH WARMER ELEMENTS & SWITCHES:
If warmer plate fails to heat, first check power source and then check ~ light on warmer switch (21 Fig 3) is lit when in the "1" position. If warmer
switch is lit, replace warmer plate by unplugging brewer, removing the two hold down ~rews on plate and withdrawing warmer plate from brewer.
Replace the new warmer plate. If warmer switch does not light, replace it. To remove sw~ch 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 sw~ch snaps in from the front.
IF WATER FAILS TO HEAT:
1. If Red power light (20 Fig 3) and warmer switches do not come on, check power source. Replace fuse or reset circuit breaker if necessary. If power
is good, check rear power switch for continuity and replace " switch stays open.
2. If water still fails to heat, disconnect line cord and check out tank heater (31 Fig 3), thermostat (14 Fig 3) and high temperature safety shutoff (54
Fig 3). Replace needed parts.
