Fetco CBS-52H-15 Kaffeemaschine Bedienungsanleitung

Ursache: No water reaching the brewer

Make sure the shut off valve is open. Check water line for kinks; replace line if necessary. Check to see if filter is clogged by changing it

Ursache: Flow discs in spray heads in upside down with flange on flow disc facing wrong direction

Reassemble spray heads - bumps on spray cutter face with flange on flow disc facing correct direction

Ursache: Water filter clogged

Replace water filter

Ursache: Spray head clogged

Clean and or replace the sprayhead

Ursache: Timer/s are set too low

Advance timers to proper level

Ursache: Incoming Voltage is too low for timers to function at proper time sequences

Reset wall circuit breaker as one side may drop out & not flag the breaker. Call an electrician to find loose connections in the building

Ursache: Water filter clogged

Replace water filter

Ursache: Weak dispense latch assembly (usually buzzes during cycle)

Replace dispense latch assembly

Ursache: Water pressure or flow rate is too low or fluctuates too much to support a full brew

Make sure brewer has a dedicated water line. Ensure that the shut off valve is open all the way (Never use needle saddle valves). Increase the diameter of the water line to the brewer and or find stable source

Ursache: Brewer is not level

With an accurate level, level the brewer front to back and left to right by adjusting the feet

Ursache: Timer/s are set too high

Adjust timers down to appropriate level

Ursache: Thermal server not empty

Empty the server and try again

Ursache: Unknown

Call FETCO Service Dept. to discuss. (800) 338-2699

Ursache: Spray head missing

Attach spray head assembly

Ursache: Improper dose

Measure and confirm correct dose

Ursache: Filter papers

Make sure only one paper is used

Ursache: Cracked dispense tube

See spray head drips MAJOR section

Ursache: Low brew temperature (Temperature inside the hot water tank is set to 205° F, the metal delivery system drops the temp)

Adjust thermostat so the water stream measured at the bottom of the brew basket, 1/3 of the way through the brew cycle, equals 190 degrees + or - 5 degrees

Ursache: Spray head missing

Replace spray head

Ursache: Half batch used incorrectly

Use smaller half batch brew basket. Discourage half batch use. Investigate the need for a smaller brewer

Ursache: Water Softener in use

Move brewer water feed to a non-softened source

Ursache: Extremely fresh coffee

Call FETCO Service Dept. to discuss. (800) 338-2699

Ursache: Bypass valve closed

Open bypass valve

Ursache: Flow disc wrong size or missing

Correct or replace flow disc

Ursache: Condensation around the sprayhead area

Wipe sprayhead area after brewing; place an empty container under brew cone when not in use

Ursache: Condensation from water tank dripping through dispense tube

Insert an empty brew basket and server under brew heads when not in use

Ursache: Cracked dispense tube/s (This problem starts out minor but gets steadily worse)

Replace both dispense tubes even if other side is not dripping

Ursache: Fill valve not sealing (Will drip even with power off)

See Brewer won't stop brewing section - Bad or stuck fill valve

Ursache: Dispense tube cracked

See sprayhead drips MAJOR section

Ursache: Mechanical binding

Re-align the brew handle / brass sprayhead tower / and dispense tube into a straight line by moving brass tower

Ursache: Water pressure over 75psi

Place a water pressure regulator on the line and reduce to 20-75 psi

Ursache: Dispense tube drive screw off. A 2.5 inch screw that connects the handle to the dispense tube at the brass sprayhead tower

Ensure that the drive screw is straight (can be straightened by hand while still in the brew handle) and reconnect to the dispense tube. The flange that the drive screw engages MUST be held flat against the brass sprayhead tower, without being able to back out

Ursache: Water level probe bad or encrusted with lime

Clean lime build up on the probe tip and/or tank wall. (Holding the probe wire (green) from the probe end to the body of the brewer should stop the fill if the probe is bad but the liquid level board is good)

Ursache: Bad liquid level control board

Replace the LLC board if grounding the probe end of the (green) probe wire to the body of brewer does not remove the voltage at the fill terminal on the LLC board

Ursache: Bad or stuck fill valve (it is not magnetic)

Rebuild or replace the fill valve if no voltage is on the coil and it still passes water to the tank. (Disconnect the outlet side to see if it leaks water to the tank)

Ursache: Incorrect dosage

Measure and confirm the correct amount of coffee required

Ursache: Short brew levels

See Short brew levels section

Ursache: No power to brewer

Make sure power switch is on. Reset machine circuit breaker. Check power connection. (plug or hard wire connection). Check building circuit breaker. (Always reset breaker by switching off, then on)

Ursache: Defective liquid level control board (No power to thermostat)

With power on, and water tank full, check LLC board for 120 volts on brown wire and neutral. Replace LLC board if there is no voltage

Ursache: Bad connections on solid state relay (No power to heaters)

Check relay for burned or loose connections. Replace with high temperature connectors if necessary

Ursache: Defective solid state relay (No power to heaters)

Check input and output voltages on relay. 120 volts on blue wire (input) but no voltage out to heaters indicates a bad relay

Ursache: Bad heating element/s

Check amperage draw on heater wires. 0 amps = bad heater

Ursache: Bad Thermostat (the thermostat believes that it is at set temperature)

Replace the thermostat and or thermal probe. It's not possible to trouble shoot the probe

Ursache: Low brew temperature setting on thermostat

See Low brew temperature under Weak Coffee section

Ursache: Brewers with more than one heater can have just one fail heater

Check amperage draw on heater wires. 0 amps = bad heater

Ursache: Hot water tank limed up

Remove access cover to the hot water tank and inspect for lime. Remove the brewer for shop de-liming if build up is thick

Ursache: Thermostat set too high for altitude (Denver etc)

Reduce temperature setting to 3 degrees below boiling at your altitude

Ursache: Defective thermostat

Replace the thermostat and or thermal probe. It's not possible to trouble shoot the probe
