QUESTION:

Hello Shane,
 
I found your shortpotting video on YouTube and found it hopefully helpful.  We have a new unit like the one in the video and the water volumes are constantly having to be recalibrated due to shortpotting.  I have already cleaned the little rubber spray valves but have not cleaned the spray plates or checked for blockage in the line  between the tank and the electronic valves--I have set the fine tune program settings for water flow to as wide open as they will go and the volume set at 1.24 gallons and we are still shortpotting..... I'll let you know how it goes with the spray plate and blockage in the line...
 
The question I have for you has to do with setting the brew time on station one.  Currently it is set at 14:30 minutes.  When I am in the programming mode and change the time down to something like 5 or 7 minutes and then go to hold the stop button down, the system kicks back to 14:30 before it will give me an STO confirmation.  On the station 3 and 4 I can change the time by holding down the Stop button, and I can change program settings in advanced settings; it's just that one brew time setting it won't let me change it.  Weird, huh?
 
Thanks in advance,
 
Dan

ANSWER:

Based on your description of programming I would say that you have a 2042ee or a 2032ee. Is there any chance you could get me the serial number to this brewer I might know what is causing your fluctuating brew volume.

As far as the issue that you are having with brew time. This only happens when you are asking the brewer to do what it cannot do. If you are trying to get a volume of water in a given period of time that the brewer calculates is not possible it will automatically change the brew time that you programmed to a time that is possible.

Now parameters 60 and 61 you said are programmed wide open this should mean you set both to 0.09 which will make the valve open for a longer period of time during each pulse. For the half batch this maybe possible but it may not for the full batch settings. It is unlikely we will be able to fix this until your flow problem is fixed.

Please get back to me with serial number and also remove the cover that is right above the spray heads and take a look at what color the dispense valves are. Please get this to me ASAP so we can fix both problems.
