QUESTION:

How do I fix a short potting issue on CBS- 51H15 brewer?

Richard

____________________________________________________

ANSWER:

There are a few reasons why a CBS-51H15 could be short potting. The most common is the flow disc (part of the spray head) was installed upside down after cleaning. The instructions for assembly are on the panel behind where the dispenser sits when brewing.

The next is water flow rate to the brewer this could be affected by a clogged filter of the improper installation of a new filter. Before you check that, make sure the water supply valve is on all the way. You would be surprised to know that this is a very common issue and is often over looked. This is because sometimes valves are accidently closed or partially closed when moving boxes around or when trying to turn the water supply off to another piece of equipment.

Check these first and if you are still short potting please let me know and I will help you further.

QUESTION:

Good Evening Shane:

My company has started with a new coffee brewing company and they have brought in your machine Fetco cbs-52h.  We have been having some issues with it and the technician takes so long to come that by the time he shows up the problem is temporary corrects itself.

The problem:

The ready light takes too long to come back on.  It makes about two MAYBE three pots of coffee and then takes forever to refill again.  I can’t even fill 5 - 20oz tea cups of water without the ready light going off. I have looked up the manual and it states it may be lime build up or the thermostat is bad. However, it is about 200 degrees when the water is coming out and I can hear a clicking which I am assuming is heater going on and off.

Can you help? My service department is useless because by the time they show up my store is no longer busy and they can no longer witness this event.

Please help.

Thank you.

Latoya

ANSWER:

It sounds to me like one of the heating elements is not drawing full amps so therefore you are slow heating.

If it is what I suspect, it should be very easy to find even when the brewer is not presenting the problem.

First thing is that the tech that comes out to look at the brewer needs to have an Amp Clamp because we need to look at the amperage draw on each heater.

With amp clamp in hand and the top of the brewer removed, the tech needs to draw water out of the brewer until the thermostat call for heat. If this is a digital thermostat this will be indicated by a yellow LED illuminating. While in the heat mode the tech should clamp onto one wire going to each heater. He will want to see about 10-11 amps per heating element.

If one is significantly lower than this then there could be several causes.

1. Bad heating element (This would show amp draw but not much)
2. Bad single shot t-stat (This would show 0 amp draw)
3. Bad solid state relay (This would show 0 am draw)
4. Rare but possible is the breaker is only partially tripped.

Knowing this information will lead the tech in the correct direction.

I hope this proves helpful. Please up date as to your findings.

QUESTION:

Our brewing CBS-62H over heats and steams. We have replace the thermostat. What can we do next?

Roger

______________________________________________________________________________

ANSWER:

Is the ready light on when it is steaming or is it off? If the ready light is on the thermostat and the temperature are doing their jobs. This could mean a stuck Solid State Relay.

However if the ready light is not coming on and you have replaced the thermostat, it is possible that the temperature probe is the cause of your issue.

Let me know what you find.

QUESTION:

Shane:
 
The dripping did start again, even worse than before...We did scrub the probe, and look in the tank. The tank did not have any scale build up at all that we could see. What do you suggest next?
 
Thanks,
 
Julie

ANSWER:

If you turn the brewer off does it stop dripping? This could take a little time to stop dripping once you get a siphoning affect going the water level has to drop completely away from the vent and the dispense tubes. If with the brewer off it stops then we need to find the cause within the machine. As I believe I mentioned before loose wire, corroded terminal so on. It sounds like it is not the probe since you cleaned it and scraped the tank. So it has to be a wire or the liquid level board.

If it does not stop, then with the brewer still off try drawing out 20 oz at a time through the hot water faucet until it stops dripping. Let the brewer sit and see if the starts to drip again. The key here is not draw too much water out; you want to draw out just enough to stop the dripping but allow water the level to build back up quickly so it will  begin dripping again.

If the brewer begins dripping again the fill valve will need to be replaced and the water supply to the brewer will have to be turned off at night until it is changed.

QUESTION:

Shane,

How do you program the water temperature on a CBS-52H?

Thanks for your help........Mark

_______________________________________________

ANSWER:

Mark,
 
To set the water temperature on a 52H you have to remove the top of the brewer. Then locate the thermostat; it is the narrow control board with the 2 digit digital display located in the rear center of the compartment directly above the spray head.
 
To adjust you will see a small black adjustment stem next to the display. Turn the adjustment stem clock wise or counter clockwise and you will see the display flash and the digits will change. Adjust to the desired temperature and then stop, a few seconds later the display will stop flashing and the display will show the current temperature.
 
To read the display is easy even though there are only two digits. A temperature below 100 degree is what is displayed without any decimal points (75). 100 degrees and higher you will see one decimal point lit and the temperature reading, so this would be the temp displayed plus 100 (.75 is 175 degrees). If there are two decimal points displayed then the temp is 200 degrees or higher; the temperature reading plus 200 (.0.5 is 205 degrees).
 
I hope you find this information helpful if you need anything else please let me know.
 
Thank you,

Hello,

I bought a used Fetco CBS-52H-15 brewer refurbished, and it has been working beautifully every day for 4 years...there is a drip coming from both sides sporatically...cannot figure out what prompts it to happen. It drips so much now that we leave a bucket underneath the brewer to catch water that drip overnight, and it fills a mop bucket about halfway. It is brewing the coffee fine.
 
What do we need to do? Does the dispenser tubes need replacing? Can my contractor husband replace these parts himself?
 
Thanks for your immediate help.
 
Julie

____________________________________________________

Julie,
 
I am very glad to here that your refurbished unit has worked so well to this point. I am sorry however that you are now experiencing trouble.
 
I think that  you are saying that this problem is not constant since you said it was sporatic. If this is the case than the dispense tubes are probably not it. This erratic problem sounds like a possible leaking fill valve or possibly something real simple like a dirty probe.
 
If your husband is handy, he can take care of any of these issues.
 
First, however, we need to verify the cause of the problem. To check if this is the liquid level probe that is causing the problem, please do the following. When you close at the end of the day turn the brewer off at the main power switch. If the brewer is dripping when you do this, drain water out of the hot water faucet until the dripping stops.
 
If the containers you usually put under the brewer are empty in the morning then it is the liquid level probe. To fix this you will have to take the top off the brewer so turning of the power to the brewer and unplugging it are in order. After you take the top off, then locate the liquid level probe. This will have a green or purple and white wire attached to it. Remove the wire and unscrew the probe. If there is any scale build up on it clean the probe with a green scrubby. Then remove the tank access cover and check inside the tank. If there is scale built up on the side of the tank, scrap the side of the tank with a screw driver. The combination of these two things will allow the liquid level probe read the water again and stop the tank from over filling.
 
Then you will need to descale the tank. I would recommend using Dezcal from Urnex to do this.
 
If however the containers are full again in the morning, then it is the fill valve and it needs to be replaced. The fill valve is located in the lower portion of the brewer. Make sure you turn the water supply valve off and turn the brewer off and unplug it. Then remove the old fill valve and install a new one. If you need the part number, please let me know.
 
If on the other hand the dripping is constant from both side and never really abates, then the dispense tubes need to be replaced. This will require the replacement of the of the dispense tube seals as well. If this is needed, please let me know and I will provide instructions for the replacement. 
 
Please let me know what you find regardless.

QUESTION:

I have a CBS -2032e Fetco Coffee brewer at my coffee shop. My problem is water comes out less than it is supposed to. I reprogrammed it and increased water volume in parameter 1-1, but still comes out short. Originally it was programmed as follows for a full brew.
 
11249
12400
14   4
15010
16030
 
Is there any parameter I should adjust to solve this problem, or should I look at another section?

ANSWER:

Ian,

I am not sure how long you have had this coffee brewer so I am not sure if you have the spray plate on or the cascading spray dome for a spray head. 

Regardless however this sounds like an issue with the spray plate. (The spray plate is a round disc with 12 holes in it for the water to pass through and onto the coffee grounds)

It is possible that the holes are clogged on the spray plate. To remove the spray plate, first make sure that the spray plate has cooled so it can be safely removed. Then very carefully loosen the knurled nut in center of spray plate bearing in mind that there is water held above the plate and when you loosen the plate it will drop out.

Once you have the spray removed from the brewer, you will want to poke a tooth pick through all twelve holes, even if it does not look dirty insert the tooth pick in the holes and ream them out. Reinstall the spray plate being careful not to cross thread the knurled nut.

Run a full brew and check your volume. The brewer should be providing the volume needed now. If however the brewer is not please contact me again and I will give you other possible causes of this issue.

QUESTION:

Hi,
I have a tea brewer at my restaurant, it's giving me an error code "0.60" if you could please tell me how to resolve the problem.

Thanks
--

_____________________________________________________________

ANSWER:

The error code 0.60 is a flow meter error. This error can be caused by a couple of issues.

1. Water supply has been shut off and flow meter is registering no flow. Turn water supply on.
2. Water pressure has dropped below 20PSI so the fill valve cannot open thus again the flow meter is registering no flow. Make sure water supply is on all the way, change in line water filter, checked for kinked water line etc…
3. Fill valve is not functioning and flow meter is not registering flow because of it. Replace fill valve.

I hope the items listed above are helpful. If you need any further assistance please contact me.

QUESTION:

CBS-52H15:   Older unit--This morning at church, turned water on to it and then the power switch on in the center of the unit--water came on and did not shut off!  Cold water started coming out the dispensers even though the fill start handles were UP. I took the top off and checked electrical connections - thought I would then  remove the "water level probe" but after a few turns, decided I needed two wrenches to remove it, so I re-tightened the probe and then tried the cycle again - turned on the water and then the power- this time the water shut off promptly and each time I turned the power on and off it seemed to shut off the water as it should.

Any thoughts? Is my probe crusted up? Bad? Poor ground on the tank? or Maybe the liquid level control (108034) is NG?

thanks - Ken

___________________________________________________________

ANSWER:

This could be a couple of things. One is your first item listed and it is possible that the a couple of turns out loosened some of the scale and exposed bare metal again or it could be that the wire to the probe was not getting good contact and when you remove the wire to remove the probe then put it back on then it had better contact and began working again.

The liquid level control board is more than likely not the cause of this issue. However the circuit that allows the liquid level board to do its job could be part of the problem.

 The wire that goes from the board to the probe (Green and White),
 The wire that goes from the board to the body of the brewer (White and Purple),
 As well as the probe itself and the tank (Scale Build Up)

I hope this is helpful information and you find the root cause of the problem. Let me know how it turns out.

QUESTION:

We have 3 side by side Fetco coffee machines and just had the health department come by for an inspection.  What we are needing to know is:  Do the coffee machines have an internal back flow valve in them?  And if so could you send me an email with verification of that for us to give to health department?  If it does not, what do we need to do to get to code with this?  Thank you so much for your quick response to this question!

Linea

___________________________________________

ANSWER:

Linea,

FETCO Coffee brewers do not have internal backflow preventers. To comply with health codes in your area we recommend the use of a Watts backflow preventer for beverage equipment model SD-2-MF 3/8” Order Code 006165.
