QUESTION:

Hi Shane,
 
We have a total of six machines on property 2 X CBS52H15 and 4 X CBS62H we cannot get the desired volumes. On The CBS52H max volume is 5 L without the coffee and the timer set at max 360 seconds
 
The CBS62H max volume is 10.4 L without the coffee grounds in brew basket, timer set at again max 360 seconds. At no time does the water in the tank falls below the siphon level of the tube.
 
The Tank, refills. The Brew Tubes are clear, used descaling spring to check. I see from the user manual that it could be a simple as the flow disk could be fitted incorrect.
 
That I have not checked, but 12 pieces? Is there any futher test / check I can carry out. I was thinking of the removing the Flow Disk Completely to see if the volume increases.
 
 
Peter

ANSWER:

Peter,

I am sorry to hear that you are having issues with your brewers. Let’s see if I can help get you back up and running properly.

First off thank you for your thorough account of what you know so far this is very helpful.

Just to summarize what I understand of what you have told me you are saying that;

1) All six of your brewers are short potting

 Both of the 2 CBS-52H15’s are short potting the same amount and it is the same on both sides for each brewer.
 All 4 CBS-62H’s are short potting the same amount and it is the same on both sides for each brewer.

2) All 12 timers (Double Units) are set to the highest time setting of 360 seconds but still having short potting issue.

3) You have checked and verified that the tank on al the brewers are refilling

4) You removed all of the dispense tubes from all of the brewers and ran a de-scaling spring through all of them to make sure there was no obstruction.

5) And you are checking all 12 flow discs to make sure they are installed correctly.

Now for a few questions:

1) If you were to brew one side at a time vs both sides at the same time does the volume change?

2) Do all 12 timers time for the 360 seconds that they are set for? (360 seconds or 6 minutes)

3) When the brewers are refilling do they fill stop, fill stop, repeat like this throughout the brew cycle or does the fill vale turn on and stay on during the entire brew?

4) Do each of the brewers have its own water filter?

5) When was the last time the filters were replaced?

Please get back to me with answers to these questions and hopefully based on your answers I will have a solution for you.
