|Unit fails to brew
|Check start switch continuity, replace if defective.
|Check timer continuity, replace if defective.
|Unit fails to stop brewing after pressing Stop Brew Switch
|Stop Brew Switch
|Check Stop Brew Switch continuity, replace if defective.
|Switch open time too short
|Press switch for longer than 1 second
|Water Solenoid Valves
|Identify which Solenoid Valve is defective. Replace Solenoid Valve if it does not close when Stop Brew Switch is pressed.
|Tea overflows from the Filter when brewing
|Check total volume of Tea. Readjust timer if necessary.
|Water Solenoid Valve
|Check both Solenoid Valves for correct flow. Replace valve.
|Water keeps running (Will not shut OFF)
|Timer is defective, will not cycle to OFF condition. Replace timer.
|Water solenoid valve (Plunger stuck open)
|Identify faulty valve. Check coil and replace coil or valve if defective.
|Water fails to heat, and brewer does not work.
|No power to brewer
|Check if power cord is plugged into wall oulet. Check line fuse or circuit breaker – if OFF, turn it ON or replace.
|If circuit continues to be open, call a qualified service agent. Defective cord or plug – repair or replace.
|Loose wires – remove front and top panels and check for loose connections, screws or terminals.
|Tighten screws, repair or replace terminals.
|Hi-limit safety control
|Push Reset (Model 8357GB)
|Check for a loose wire or connection. Repair and/or reconnect. Disconnect wires and check for continuity on both terminals of the hi-limit safety control.
|If continuity is present, the control is functioning properly, if not, replace hi-limit.
|Unit damaged due to hook-up to wrong voltage.
|Check source receptacle for single phase or mis-wired power receptacle.
|Water fails to heat, but brewer does work.
|Switch in OFF position – turn ON. Defective switch, replace switch.
|Check for loose wire or connection. Repair or reconnect.
|Check for proper voltage at tank heater terminals. If voltage is present, element is defective, replace element.
|Check for loose wire or connection feeding into the thermostat.
|If ready light Is ON turn the thermostat adjusting shaft CLOCKWISE to the full ON position. If ready light goes out, water should begin to heat, adjust to proper water temperature.
|If ready light stays ON, replace the thermostat.
|Ready light fails to glow when water reaches brew temperature
|Ready light is defective.
|If thermostat cycles ON and OFF and ready light does not glow, replace ready light.
|Water heats, but is not hot enough
|Thermostat needs adjustment.
|If water from the spray elbow (with spray disc removed) Is not hot enough for proper brewing, and thermostat cycles the tank heater OFF, adjust the thermostat to a higher setting. 1/2 turn equals approximately 18?F (10?C) temperature change. To INCREASE the tank temperature, turn the adjustment shaft in a CLOCKWISE direction.
|If adjusting thermostat to a higher setting does not correct the problem, the thermostat is defective, replace it.
|Hi-limit safety control (Ready light does not come on)
|Hi-limit safety control is defective. Replace it.
|Water heats, but takes a long time. (Slow recovery)
|High lime deposits.
|Low voltage at source.
|Check voltage. It should be within 10% of unit rating plate. If a low voltage condition exists, an electrician should be consulted.
|A low voltage condition can and does cause frequent service calls, as well as extending water heating time.
|Low voltage at tank heater.
|Voltage rating and power source must be the same. Check wiring diagram and re-wire.
|Water temperature too hot. (Steams, Bolls or heat never shuts off)
|Thermostat out of calibration or defective. Adjust or replace It.
|Dry Tea remaining in the brew funnel after a brew has been completed.
|Spray disc missing.
|The spray disc must be in place to break up the water stream.
|Use proper filter papers.
|Improper loading of the brew funnel.
|Filter should be centered in the brew funnel and the tea bed should be level.
|Tea grounds do not get wet – water leaks out of the bottom of the unit.
|Leak In water path
|Check for correct fit and leakage at all fittings and tubing assy, tank cover gasket and bypass tubing.
|Too much water
|Adjust timer/Decrease volume or change grind.
|Water temperature too low
|Adjust thermostat to a higher setting
|Improper loading of brew funnel
|Filter paper must be centered in brew funnel. Tea bed must be level when staring a brew cycle.
|Inconsistent volume of Brew
|Receiving Dispenser not empty when a brew cycle Is started
|Always start with an empty receiving dispenser when a brew is started
|Water pressure too high or fluctuating.
|Check flowing water pressure to see if it exceeds 90 PSI at anytime, a pressure regulator should be installed in the water supply line.
|Water continues to flow. (Will not shut OFF if power is disconnected)
|Check start switch continuity and wire connections if valve closes. Replace/repair if defective.
|Solenoid Valve is defective If does not close after brewed cycle. Replace Solenoid Valve.
|No water from the spray disc (when brew switch is activated)
|Be sure water shut-off valves are open.
|Check line fuse or circuit breaker. If OFF, turn ON, or replace fuse. Make certain unit is alone on its own electrical lines.
|If fuses or circuit breaker continue to open, call qualified serviceman.
|Loose wire or connection
|Remove unit top cover and front panel.
|Check all wires and connections, be certain none are loose or disconnected.
|Repair loose connections, and/or wires and reattach.
|Strainer (in solenoid)
|Strainer may be plugged – clean screen or replace
|Start Brew Switch
|Check switch continuity. If switch does not make and break contact, replace switch.
|When Start Brew Switch is pressed, the timer should activate. The timer should continue to operated until the cycle is completed. If not, replace the timer.
|Water Solenoid Valve
|Check both solenoid valves for continuity at the terminals of the solenoid valve coil. If no continuity, replace either solenoid valve coil or the complete solenoid.
|Check both Solenoid Valves for correct flow. Replace valve If it varies more than 10% of it’s gpm (gallons per minute) required.
|Brewed volume Too much Tea or too little Tea
|Timer need adjustment. Turn timer adjustment for desired volume change, turn CLOCKWISE to INCREASE the volume or COUNTERCLOCKWISE to DECREASE the volume.
|Check timer cycle several times with a stopwatch. If times are Irregular, replace the timer.
|Turn at small increments to avoid large volumn variation.
|Flow restrictor in output end of water solenoid valve
|Dirty, missing, damaged or inoperative flow restrictor. Replace the water solenoid valve. Particles in the water solenoid valve may partially clog the orifice to the flow restrictor.
|Water pressure variations
|All automatic brewers require a constant water pressure between 30 and 70 PSI for consistent, trouble-free operation.
|Wide swinging water pressures lead to erratic delivery. A pressure regulator may be needed to stabilize high running pressures.
|A water source that falls below 30 PSI results In short pots or erratic volume delivery.
