• Solenoid removal requires interrupting the water supply to the valve. Damage may result if solenoids are energized for more than ten minutes without a supply of water. • The use of two wrenches is recommended whenever plumbing fittings are tightened or loosened. This will help to avoid twists and kinks in the tubing. • Make certain that all plumbing connections are sealed and electrical connections tight and isolated. • Keep away from combustibles. WARNING – • Exercise extreme caution when servicing electrical equipment. • Unplug the dispenser when servicing, except when electrical tests are specified. • Follow recommended service procedures • Replace all protective shields or safety notices 28791.1 011500 4 TROUBLESHOOTING (cont.) PROBLEM Product will not dispense Motor thermal cutout (motor stops running) PROBABLE CAUSE 1. Empty product container 2. No power or incorrect voltage to the dispenser 3. Signal cable unplugged 4. Hopper is full 5. Fuse and fuse holder 6. Main ON/OFF switch 7. Probe box LOW/OFF/HIGH switches 8. Circuit board 9. Vacuum switches 10. Vacuum/Supply pump 1. Motor over heats REMEDY Replace or refill (A1) Check the outlet for 120 volts on two wire 120 volt dispenser. (A2) Check the outlet for 200 volts or 240 volts ac for two wire 200 volt or 240 volt dispensers. (B) Check circuit breakers or fuses. Signal cable must be plugged in. Product must not be touching probes to fill. Refer to Service - Fuse and Fuse Holder for test procedures. See page 8 Refer to Service - Main ON/OFF Switch for testing procedure. See page 9 Refer toService- Probe System. See page 10 Refer to Service- Circuit Board for testing procedures. See page 7 Refer to Service- Vacuum Switches for testing procedures. See page 14 Refer to Service - Vacuum/ Supply Pump for testing procedures. See page 12 The thermal switch will reset, but requires up to 30 minutes of cooling time. See NOTE below.
