.CAUTION - Disconnect the power source from the brewer prior to the removal of any panel for the replacement
or adjustment of any component. The water level can be adjusted. On almost all cw series coffee makers there is dip switch located on the circuit board behind the front panel. The dip switch(very small black or white) should not, not be in the on position. Making sure the switch is not in the on position(it should be swithced towards the set positon), put the front panel back on. Read and follow the instruction here after..

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 two seconds 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, two seconds 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 two-second 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 two seconds 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

Keeps spilling over during brewing

These tanks can't actually be overfilled since all water poured in displaces the exact same amount of water coming out the spout. So, whatever amount of water you pour in, will be the same amount of water that flows to your pot minus the amount absorbed by the coffee grounds and filter.

Your problems sounds like an undersized (Non Bunn) filter, or clogged brew basket. To verify this, try pouring in only half the water for your brew cycle and wait for it to finish dripping, then pour in the rest. If no overflow has occurred, you simply have the wrong type of filter. If overflow begins again, you have a clogged brew basket, since no Bunn can flow too fast for the brew basket to keep up with it.

This is because Bunn filters are manufactured differently than generic store bought paper filters. They will flow faster, brew cleaner and stand up better than normal generic filters.
Remember, Bunn makes their OWN filters for good reason.
They made the first, best paper filters for drip coffee pots, and all others are just generic dioxin gas producing paper.

Coffee is in water is in nothing happens

You may not have enough water in the tank.
Follow these steps

1. With the coffee pot unplugged, fill your resevoir/tank until water begins pouring out of your sprayhead and brew basket.
2. Wait for the water to finish dripping then plug in your Bunn.
3. Let your Bunn warm up for at least 8 minutes.
4. Run a test cycle with clean water, remembering to use the water pitcher provided for this purpose, while leaving your empty pot on the burner beneath the brew basket.
5. If your cycle completed, and your coffee pot is filled to the desired level you are ready to make coffee.

Remember that these Bunn models have no water filter2_bing.gif installed, so, the cleaner the water the better tasting the coffee.

First brew a pot without water, to find your current level. Next open the faucet and check the water flow, if it has a nice flow no stopping or spurting, then your water connection is good. Now adjust the brew level, the adjustment instructions are on the inside of the front panel. If after making adjustments you get the same result then the solenoid is blocked.

Bunn omatic won't make full pot-even with water line hooked up

Use the dial with numbers on it and adjust to a higher number. Remember to go in half steps such as 2 adjusted to 2 1/2, 3 adjust to 3 1/2 etc.

If you only have a High Low knob, that is to set your water temp.

If you have an electronic circuit board, you will need to follow the batch instructions pasted on the inside cover (facing the lower burner) to adjust for water level/batch. This cover has 4 screws.

Water over filling pot

There is a brew timer on the left side of your machine near the heater switch. you need to remove an access panel to access it. turn this down a little, let the water heat up, then try another brew. Adjust as needed, brewing another pot between each setting.
