There are two problems that are nearly impossible to fix: failure of one of the heat-sensitive switches and failure of the heating coil. Because it's very challenging to get replacement parts, you'll probably have to buy a new coffee maker if one of these problems disables your machine.
The power cord or on/off switch can go bad. In either of these cases, it's best to get a pro to replace it or buy a new coffee maker
The one-way valve can get clogged open or closed. You can usually fish out the debris that causes this problem with a toothpick. If you use house water softener it might over saturate the coffee and causes problems with the machine.
The tubes can get clogged with calcium.For the same reason tap water can cause deposition inside the machine This is especially true of the aluminum heating tube. The normal way to solve this problem is to run vinegar through the machine once, and then run two batches of water through to clean out the vinegar.
Good Luck

You'll need to do continuity checks on the pstat contacts (probably OK given the heating light), the heating element itself, and check if there's an SSR on the circuit. If there is, it shouldn't be dropping more than 1 or 2 volts across the power side when its on; if it's reading a full 110, or a large voltage, it's dead

Adjust bunn coffee maker water level


To adjust the brew volume/batch size you will need to access the main circuit board behind the front panel. Isolate the machine before removing panels.

NOTE: Check that the brewer is connected to water supply, the tank is properly filled and a funnel and server or decanters are in place prior to setting or modifying batch sizes.
  1. Modifying batch sizes: To modify a batch volume, first check that the SET/LOCK switch is in the "SET" position on the circuit board. If the brewer has a batch selector switch, position it to the size to be changed. To increase a batch size: Press and hold the START or BREW switch until three clicks are heard. Release the switch (Failure to release the switch within 2 secs after the third click causes the volume setting to be aborted and previous volume setting will remain in memory) and press it again one or more times. Each time the switch is pressed, 2 secs are added to the brew time period. Allow the brew cycle to finish in order to verify that the desired volume has been achieved. To decrease a batch size: Press and release the START or BREW switch once for every 2 sec interval to be removed from the total brew time period; then immediately press and hold down the START or BREW switch until three clicks are heard. Release the switch. (Failure to release the switch within 2 secs after the third click causes the volume setting to be aborted and previous volume setting will remain in memory). Allow the brew cycle to finish in order to verify that the desired volume has been achieved.
  2. Setting batch sizes: To set a batch volume, first check that the SET/LOCK switch is in the "SET" position on the circuit board. Press and hold the START or BREW switch until three clicks are heard (this will take approx. 10 secs) and then release the switch. (Failure to release the switch within 2 secs after the third click causes the volume setting to be aborted and previous volume setting will remain in memory). View the level of the liquid being dispensed. When the desired level is reached, turn the ON/OFF switch to "OFF". The brewer remembers this volume and will continue to brew batches of this size until the volume setting procedure is repeated. Empty server(s), turn selector switch to positions that have yet to be set and repeat batch setting procedure until all batch sizes are set.
    NOTE: When brewing coffee, batch volumes will decrease due to absorption by the coffee grounds.
  3. Setting programming disable feature: If it becomes necessary to prevent anyone from changing brew times once
    programmed, you can set the SET/LOCK switch to the "LOCK" position. This will prevent any programming to be done.
    NOTE: If the clicks cannot be heard, lightly grip the incoming water line to feel when the valve cycles on and off.

Tip

How to calibrate a Bunn CWTF commercial coffee brewer


1. you need a 64 ounce graduated measuring cup or bucket
2. make sure the brewer is heated up to temp and the green light on the front is lit
3. open the front panel of the brewer
4. put the microswitch on the circuit board to "unlock" position
5. make sure the sprayhead is cleaned and open, the brew basket is on, and the measuring cup is in place to catch the water
6. press and hold the brew switch until the inlet solenoid clicks 3 times, then release
7. once the water level is at about 40 ounces, turn the main red switch off and let the rest of the water come out
8. if it brews short, press and hold the brew switch again until the 3 clicks, then press and release the brew switch for 2 more second of brew time (up to 5 times per brew)
9. if it brews too much, press and release the brew switch for two less seconds of brew time (up to 5 times), then press and hold the brew switch until the 3 clicks then release
10. once you get to 64 ounces, put the switch on the circuit board to lock and replace the panel
11. enjoy!

Saeco vienna plus red solid light cannot prime water line


Make certain the line from the water resource is cleaned and not obstructed. If the pump fails to move the water from the reservoir to the heating tank, then the pump needs to be replaced.

While holding down the switch you will hear the solenoid start and stop 3 times. You should have to hold down the switch for about 10 seconds to get the program started. Make sure the white lever on the board is not on the L.

My Saeco Vienna Black Automatica Espresso maker will grind coffee only about one-fourth of the time. Other times, it makes whirring sound and then shuts off and red "coffee bean" light comes on.


Your grind is to fine. Turn the big knob in the bean hopper up 4 clicks and try again. It could be oily beans which would require the same solution.

No water/coffee comes through? the temprature indicators doesnt light up?


The POWER LIGHT for the 889 is RED and located on the LEFT of the center cowling

The BOILER LIGHT for the 889 is YELLOW and located on the RIGHT of the center cowling

If you turn on the power to the unit (the INNER SWITCH on the RIGHT SIDE) the RED light should turn on, showing that the machine is powered. At that point the YELLOW light should also turn on for about 10 seconds, at which point it will turn OFF with an audible CLICK.

If the RED light does not turn on then you have a very dead machine.

If the RED light does turn on but the YELLOW light does not then you have a half dead machine.

Opening up and repairing the 889 is not for amateurs. High voltage, heat and pressure inside.

If you decide to bin the machine I would appreciate getting the drip tray from you as I have lost mine.

To program the Auto On
1. Set the desired Brew-Start time.
a. Turn the FUNCTION KNOB to “Prog”.

the To set the time section above.
2. Turn the FUNCTION knob to the “Auto On”
position. LCD will display the current time.
3. Lift and release the FLIP SWITCH. The

you that the programming function is in use.
At the programmed time, the red light will
come on as well, indicating that the brew
cycle is starting. Both lights will go off when
keep warm cycle ends.
NOTE: To reactivate the auto-on feature to
start brew cycle at the same time another day,
simply lift and release the FLIP SWITCH. The
green “auto-on” light will illuminate.
