TROUBLESHOOTING 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 120-240 volt ac and low voltage dc potential on their terminals.
TROUBLESHOOTING (cont.) PROBLEM PROBABLE CAUSE REMEDY Temperature Too Low 1. Water temperature in the tank does not meet the ready temperature. A) Wait for the brewer to heat to the proper temperature. Heating Time Too Long 1. Tank Heater failure. 2. Control Board/Thermistor failure Fill Time Too Long 1. Water shut off to brewer 2. Inlet Solenoid failure 3. Control Board Failure 4. ON/OFF switch is OFF Temp Sensor Out Of Range, Check For Bad Connections 1.
TROUBLESHOOTING (cont.) PROBLEM PROBABLE CAUSE REMEDY Brew cycle will not start 1. No water Check plumbing and shut-off valves 2. No power or incorrect voltage to the brewer Check for voltage across the terminals at the terminal block. 3. ON/OFF switch Test the ON/OFF switch. 4. Brew switch Test the BREW switch. 5. Brew valve Test the brew valve. 6. Control Board Substitute a control board known to be in good working order.
TROUBLESHOOTING (cont.) PROBLEM PROBABLE CAUSE REMEDY Automatic refill will not operate or display shows FILL TIME TOO LONG 1. No water Remove the strainer and check for obstructions. Clear or replace. 2. Refill probe or Sensitivity setting Check the sensitivity setting. Refer to the REFILL function. If the left three digit number is less than the right number, the machine “thinks” it is full and the refill valve should be off.
TROUBLESHOOTING (cont.) PROBLEM PROBABLE CAUSE Automatic refill will not operate or display shows FILL TIME TOO LONG (Continued) REMEDY not present, replace the refill valve. If continuity is present, the coil may be stuck closed. Shut water off to brewer. Press the ON/OFF switch to turn off the brewer. Open the faucet and drain water down in the tank until flow stops or slows to a trickle. Attach a voltmeter to the terminals of the refill solenoid. Connect the brewer to the power source.
TROUBLESHOOTING (cont.) PROBLEM PROBABLE CAUSE REMEDY Water flows into tank continuously with power removed from brewer. 1. Refill valve Foreign material lodged in valve, holding it in open state. 2. Refill probe or sensitivity setting Check the sensitivity setting. Refer to the REFILL function. If the left three digit number is less than the right number, the machine “thinks” it is full and the refill valve should be off.
TROUBLESHOOTING (cont.) PROBLEM PROBABLE CAUSE REMEDY Water will not heat or display shows HEATING TIME TOO LONG. 1. Limit Thermostat Remove power from the brewer. Check for continuity through the limit thermostat. CAUTION: Do not eliminate or bypass limit thermostat. Use only replacement part 29329.0001. 2. Temperature probe Remove the probe from the grommet and submerge in a water bath of approximately 70°F (21°C). Connect an ohmmeter to the pins in the connector.
TROUBLESHOOTING (cont.) PROBLEM PROBABLE CAUSE REMEDY No bypass water 1. Bypass valve Test the bypass valve. Refer to the test outputs. 2. Recipe settings 1. Lime buildup Check to make sure bypass % has been set for the current recipe. Inspect the probe and tank assembly for excessive lime deposits. Delime as required. 2. Temperature probe Remove the probe from the grommet and submerge in a water bath of approximately 70°F (21°C). Connect an ohmmeter to the pins in the connector.
TROUBLESHOOTING (cont.) PROBLEM PROBABLE CAUSE REMEDY Inconsistent beverage level in server/dispenser 1. Improper water pressure Check operating water pressure to the brewer. It must be between 20 and 90 psi (138 and 620 kPa). 2. Brew valve Test the brew valve. Refer to test outputs on page 48. Turn the valve on for 30 seconds and collect the water dispensed from the sprayhead. Repeat the test several times to confirm a consistent volume of dispensed water.
TROUBLESHOOTING (cont.) PROBLEM PROBABLE CAUSE REMEDY Dripping from sprayhead. 1. Brew valve Repair or replace leaky valve Water overflows filter. 1. Type of paper filter BUNN paper filters should be used for proper extraction 2. No sprayhead Check sprayhead 1. Beverage left in server from previous brew The brew cycle should be started only with an empty server under the funnel. 2.
TROUBLESHOOTING (cont.) PROBLEM PROBABLE CAUSE REMEDY Weak beverage. 1. Type of paper filter BUNN paper filters should be used for proper extraction 2. Coffee For coffee, a sufficient quantity of fresh drip or regular grind should be used for proper extraction. 3. Sprayhead Bunn-O-Matic sprayhead should be used to properly wet the bed of ground coffee in the funnel 4. Funnel Loading The BUNN paper filter should be centered in the funnel and the bed of grounds leveled by gently shaking. 5.
