Low beverage serving tempera- ture

PROBABLE CAUSE

 

REMEDY

1. Sprayhead

 

Make sure sprayhead is present

 

 

and holes are clear and unob-

 

 

structed. There should be six sepa-

 

 

rate streams of water coming out

 

 

of the sprayhead.

2. Funnel loading

 

The BUNN¨ paper filter must be

 

 

centered in the funnel and the bed

 

 

of grounds leveled by shaking gen-

 

 

tly.

1. Warmer

 

Disconnect the brewer from the

 

 

power source. Remove the warmer

 

 

plate and turn upside down to ex-

 

 

pose the warmer terminals. Re-

 

 

move the two wires. Check for

 

 

continuity across the two warmer

 

 

terminals. If continuity is not

 

 

present, replace the warmer ele-

 

 

ment (See page 32). If continuity

 

 

is present, reconnect the wires to

 

 

the warmer element. Check for

 

 

voltage at the warmer terminals.

 

 

Turn the warmer switch "ON". The

 

 

indicator light will come on. Volt-

 

 

age should be present at the ter-

 

 

minals. If not, disconnect power

 

 

supply and check wiring and

 

 

switch.
