Bunn FPG-2 ユーザーズマニュアル

A troubleshooting guide is provided to suggest probable causes and remedies for the most likely problems 

encountered. If the problem remains after exhausting the troubleshooting steps, contact the Bunn-O-Matic 

Technical Service Department.

•  Inspection, testing, and repair of electrical equipment should be performed only by qualified service

personnel.

•  All electronic components have ac voltage and dc voltage potential on their terminals. Shorting of ter-

minals or the application of external voltages may result in board failure.

•  Intermittent operation of electronic circuit boards is unlikely. Board failure will normally be permanent.

If an intermittent condition is encountered, the cause will likely be a switch contact or a loose connection 

at a terminal or crimp.

•  Make certain that all electrical connections are tight and isolated.

•  Exercise extreme caution when servicing electrical equipment.

•  Turn power OFF when servicing, except when electrical tests are specified.

•  Follow recommended service procedures.

•  Replace all protective shields or safety notices.

Grinder will not start.

(A) Plug-in the grinder.

(B) Check the voltage at the wall 

outlet with a voltmeter. It must be 

120 volts ac for 120 volt models, 

100 volts for 100 volt models, and 

230 volts for 230 volt models.

(A) Momentarily press the Off/On/

Start switch to the “START” posi-

tion.

(B) Refer to Service - Off/On/Start 

switch for testing procedures.

Press the “Reset” button, located on 

rear of the grinder. Listen carefully 

for a “click”. This resets the motor 

protection circuit and indicates that 

an overload may have been encoun-

tered by the motor.  (An overload can 

occur when something other than 

coffee is inserted into the hopper for 

grinding). Refer to Service - Circuit 

Breaker for testing procedure.

Refer to Service - Timer for testing 

procedures.

1. No power or incorrect voltage

2. Off/On/Start switch

3. Circuit Breaker (Not applicable on 

Model LPG with capacitor)
