QUETSION:
Hi - I have a CBS -2031e coffee brewer using 120 volts that has been used for 5 1/2 years in a cafe. The water supply has an in line filter. The recovery time has become prolonged - when hot, I can get two pots done in eleven minutes then it locks up because of "low Temp" (171) and it takes about ten minutes to get back to useable temperature and I can get two more pots. So, I can get 6 pots an hour which is not enough. There was a thin layer of scale on one of the electrodes so I cleaned that with a descaling solution and that cleaned up well. But still no change in the recovery time. Any suggestions?
Thanks for your help.

Wendell,
You mentioned in your e-mail that this brewer “has been used for 5 ½ years in a café” am I correct in assuming that it is still in that same café under the same demands? Or has this brewer been moved to another location and now has different demands on it? While it would be good to get this information before I supply any kind of answer please see below for a preliminary assessment.
Assuming that your brewer has the standard 2.3 KW heating elements the maximum output at 120V is 7.4 batches per hour that is also assuming that the temperature of the water supplied to the brewer is at least 68°F and that the brewer is set to factory defaults for volume, brew time, pre-wet, and drip delay. In addition this also assumes that your voltage is 120V, not 115V, or 110V; if it is below 120V or any of the above parameters are higher than factory default the productivity will potentially drop.
If we are looking at a scenario where the brewer is outside of the above listed specification it is very possible that your brewer is operating at peak efficiency.
The only solution to this is to take advantage of the brewers capability of being converted to a 120/208-204V machine. If you need an explanation of how this done please let me know and I will provide you with the instructions for doing so.
I hope this is helpful information, please let me know if there is anything else I can do for you.

Hi,I was wondering the most effective method to descale a CBS-2031e? The filter cartridge needed replacing a long time ago and my ignorance has cost me dearly. Would you suggest avoiding the use of solutions and just drain the machine and physically remove the scale? Or are there powders/ liquid solutions on the market that work well but do not inhibit the flavour of the water in tank?

We use a CBS-2052, 208v, 30 amp brewer that has served us well for the last 2 years. Very recently it has began taking an extended amount of time to re-heat between brews. What can cause this and how can we tell what it is?
Thanks,
Beth

Beth,
I am glad to hear that your 2052e has served you well at the same time I am very sorry to hear that you are experiencing trouble with it currently.
The problem you described has several possible causes from a bad heating element to scale build up on the heating elements or temperature probe.
I do not know if you have any testing equipment but the first thing that I would check is the amperage draw on each heating element. If the brewer is hooked up single phase then only two heating elements will be active (one on the left and one on the right) if the brewer is hooked up to 3 phase power all three heating elements will be active.
Each heating element should pull around 10amps. If one of the heating elements is not reading at all, it is possible that the triac that supplies power to the heating element is not closing or that the single shot t-stat is open not allowing power to the heating element. If the amperage reading is low then this would indicate a bad heating element. If the amperage draw is where it should be or a little higher then it is a scale issue and the tank needs to be de-scaled.
I hope that this information is helpful and if you need any further assistance please let me know.
