Very fresh coffee and softened water with too much sodium content will cause the grounds to violently overflow. On the CBS2032 you can play with the prewet percentage and dwell time to help the situation. As far as random water dumps we had some issues untilled I upgraded to their cascading spray domes.

Is it overflowing filters? If so, you may be using the wrong one.<br />
<br />
You should not have to grind in advance to prevent overflow.<br />
<br />
These brewers tend to be quite robust and easily repaired by a qualified technician. They will occasionally break (as all things do), but when they do they are repairable. Short of failed weld on a reservoir or being dropped (or used as a stepladder to erase the menu board - seen it) these things can generally be repaired pretty quickly and easily.<br />

fetcos and newer bunns have a dump valve and do not work like your standard bunn. if you have water coming out of the sprayhead (not the overflow valve off to the side) you need a valve kit or a cleaning of the valve. if the water is coming out of the little hole behind the sprayhead, the problem could be with the fill valve or fill probe. if the brewer doesnt generate a fill error, its a leaky fill valve.<br></br>

<br/>
all brewers will sometimes blow out extra water under heavy usage. all that cold water coming into the tank will expand as it heats and come out either the overflow or sprayhead (depending on the brewer.) this happens much more often on brewers without cold brew lockout or lockout disabled.<br/>
<br/>
also, i have never seen a fetco extractor series send water to where its not supposed to be. Thanks Brady...

Thanks Brady...<br />
<br />
We were actually on the phone with Fetco for an hour today...not much insight there.<br />
We have all techs on deck for Friday morning. I will post results for those who experience<br />
this problem.<br />
<br />
Someone mentioned that because our coffee is so fresh and we grind right before brewing that perhaps the gases in the coffee are causing an increased bloom. Not sure if thats the case. What do you do?<br />
Pre grind and let rest or grind for each air pot before brewing?<br />

What is your thermostat set to? If it is near the boil, small fluctuations may cause it to randomly boil. Check the temp of the water inside the tank with a good accurate thermometer and drop your set temp just a bit if it is too high.<br/>

On the Bunn CWTs (thermal pourovers) that have been plumbed in, water overflowing can be due to water pressure being too high. These ship with pressure reducers on the back, but sometimes they get lost when sold used.<br/>

Hi Bob,<br />
<br />
Thanks for the quick response. Previous owner had a Bunn ICB Twin that would occasionally<br />
blow water and steam and it was such a violent release once that water got into the circuitry and<br />
fried the board (causing a small fire). We bought the business and repaired the Bunn but used<br />
our backup Fetco CBS 2032 and had it happen to this machine.<br />
<br />
We recently purchased a very new Fetco 2032s and are afraid that this one will fry too...Equipment<br />
