Question about Sunbeam Cafe EM6910

1 Answer

Group head not running

My double shot basket is not allowing much coffee/water through. I have cleaned the unit and noticed the screen sections above the screw were quite full of coffee residue and pretty blocked. I soaked the basket in cleaning solution and tried boiling it in a saucepan, obviously i have used the pin thing to clear out the hole. I am starting to worry the machines pressure is the problem. It's only about 9months old and makes about 8 cups per day. I'm a few hours away from civilisation so i would prefer to fix at home if i can.

Perform a full descale. Take out the water reservoir and remove the Anti-calc filter. Put in 500ml (1 pint) water with 3-4 tablespoons of white vinegar (or apple cider vinegar). Put the water canister back in, the turn on the machine and press the manual button. Allow half of the liquid to go through, then stop. Leave the machine for about ten minutes, and then run the rest through. Empty the water reservoir and rinse, put back the Anti-Calc filter, put in another 500ml and press the manual button to flush it all through.

Espresso shots pour very slow for both the single and double shots.


Did you try adjusting the group head screw? And/or cleaning and checking the valve in the group head? Good visuals and instructions here: https://myprojectsandmods.wordpress.com/2014/10/27/delonghi-ec702-espresso-machine-no-water-flow-fix/

La Cimbali junior group head leak after restore


Group head leaks can be caused by group gasket, portafilter basket (cup), valve, pipe fittings. Call back your service tech.
* Check group gasket and position of portafiler handle when pulling shot. The handle needs to point directly at you (your chest) if it points to your left shoulder or pops off the group then the gasket is worn, not correct size, missing spacer.
* If the handle points to the right shoulder then the gasket is, too thick, too many spacers, or it was installed without removing the old coffee (crud) from the group head and is stuck under the gasket. Remove and check group gasket and spacers.
* If the handle points directly at you but portafilter still leaks then check the basket (cup) insert. Many Barista's smash the portafilter on a bumper. If the bumper is worn and the metal bar is exposed then the basket insert will have a flat or dented lip. Check all your inserts for damage and replace worn bumper (a piece of water hose cut to size works)
* Still leaking? Remove cup tray above group and check group head for leaks around the pipes and fittings. Note: water discharge from bottom of group valve is normal DURING the pulling of a shot. It should not continue to drip water after pulling the shot.
* Still leaking? The group head needs to be checked.
* Pump, water lines, Water by-pass, Economiser, Hot water wand, and all the water fittings.

Making very bitter espresso. I already decalcified it and ran empty tanks through, without success.


Hi. The bitterness you have got is most likely to be dirty group head and shower. Remove the shower and clean with a steel wool. The group handle and filter basket will also have to be cleaned. Sounds like your using a dark oily blend. You cant use different blends unless you clean the group head every time. Same with the grinder. You can not use different blends for grinding. The different blends just cross contaminate, which can make your coffee bitter. Incorrect grind or wrong water tempreture can also make bitter coffee. Running descale does nothing for the coffee taste. Descale only cleans the lime/calcium in the boiler. Coffee does not pass through the boiler. Give your group head and handle a clean, and you should be right. Hope this helps. Dazza

I am using my new silvia with the ese pod adapter with illy pods. When I press the coffee dispense button with a pod in place, coffee begins to come out of the right orifice, then after a few seconds it...


"leaks noisily from what appears to be the contact between the grouphead and portafilter"
* Leaks from top of portafilter and group head are caused by poor sealing at head gasket.
* wipe top lip of portafilter before inserting into group.
* check if group is clear of coffee grounds, paper bits, tissue, dry crud. Use a head cleaning brush (tooth brush works) and wipe group clean (do not use screwdriver to scrape!)
* Make sure when inserting portafilter it is seated properly. (check your manual for procedure) Note the position of the portafilter handle if it's in the right position AFTER you tighten it. Is it far to the left? or stuck and barely hangs on to group?
* Barely hanging on to group? Check if pod is too big. Note; you can't double shot or use 2 pods in a single pod basket! Make two separate shots for a double.
* Handle tightens but slips off group or still leaks when pulling shot? Worn out or missing gasket. Gaskets are made of rubber and can crack, drop out, or pit. You will need to have the gasket replaced. Check with vendor or MFR for service/parts.
* Make sure you have the correct portafilter. Many look the same and may even fit but when making fine adjustments or critical shots they don't work right. Check manual or vendor for confirmation.
* Make sure you have the correct basket. The portafilters may have different baskets or cups that can be inserted. Many have special uses that can affect the pull of a shot. Fewer holes causes slower flow and longer brew time. Many holes gives a weaker shot but smoother less bitter taste. There is a blank basket that has no holes which is used for backflushing and cleaning of the group. Check your manual or vendor for which basket you should be using. Odds are that you have a standard basket ment for ground coffee and not pods. (you can remove the coffee from the pod but it will be messy.) Ask for the optional 'POD' basket insert.
* Finally if everything checks out and your still having leaks then your machine needs service as the group head or valve needs replacement. Call your vendor or MFR direct.

P.S. Looking back at my service with pod conversions, I've found that most if not all pro-machines don't really like the pod adapters. Sure it will work but shots are weak and poor. Pods really like a very tight fit with a very small portafilter basket(chamber) I mean like the size of a soup spoon! They like very slow and very hot water pumped with a vibration type pump to extract all the essence from the paper filtered coffee. Illy is an excellent coffee pod with a very rich aroma and good creme. The best for them (pods) are the dedicated pod machines (won't do ground coffee, only pods). If you must use a pro semi-automatic machine then I would suggest adding a port constrictor to the portafilter output. There may be a third party supplier that has a compatible adapter for your brand. I've come across some of these very extreme tools for the elites coffee affectionato. It restricts the flow at the output thus causing the hot water to brew longer and at a higher pressure to force the hot water and steam into each coffee grain. (think pressure cooker) Some of the better ones are adjustable. But note that these will need daily or cleaning after each use as these restrictors have very tiny holes which clog unless flushed after each use. Good luck 9on your pursuit of the perfect cup!)

We have a brilliant Briel Multipro that we use every day but when we have made a cup of coffee and release the coffee holder, steam and hot water spurts from the head area...It stops after a few seconds...


First, I'm NOT a Briel technician, But if you still have pressure from the removal of the portafilter (or capsule) then the exit or pour spout is clogged. You can soak a standard portafilter in warm water over nite and wash it clean in the morning. Really bad? then soak in urn cleaner and flush thoroughly prior to use. For capsule machines follow the MFR's instructions to properly flush the machine. You may also try to "fool" the machine into making a 'no coffee' shot by reusing old capsules over and over again to try and flush out old coffee from the spout. Otherwise the unit may need servicing to remove the clog as most of these capsule machines do not have serviceable parts. Contact your vendor or MFR directly for service or replacement.
*warning! Try not to stick a pin, nail, or paper clip into spout(s) as this may damage valve or offset the dual pour spout. Most of these machines have double spouts and can be easily pushed out of alignment.
* Final; I've noted that your probably using a portafilter type machine. If you have water or steam dripping from head then there is a leak in your head valve or commonly called the 'Group Valve'. Fortunately this is a serviceable part and can be replaced by your vendor.
PS. Have you tried 'Back Flushing? Use a "BLANK" portafilter basket (the one with no holes) or a back flush rubber stopper (from Cimbali). Add a 1/4 teaspoon of urn cleaner of flush cleaner to portafilter and lock onto group. Run shot till it stops (excess pressure and dose will by-pass the group valve. This will flush old coffee and crud out the by-pass pipe and into drain tray. If nothing happens and the group hums for longer than 20 seconds then your probably got a clogged valve and back flush pipe. All will need disassembly, cleaning and/or replacement. Best to call your Vendor for service.
*Be sure to run the group several times and wash the portafiler to get rid of the urn cleaner.
*Tip; It's a good idea to back flush every hour with with plain water from the shot to just get rid of the coffee grounds stuck to the group shower head and leftover coffee in the group valve. Does not hurt the machine and keeps everything working smoothly.

Solis SL 90 occasional pressure loss, only a few drips of coffee before it switches itself off. Cleaning sometimes helps or not using for a bit.


HI
There are a few things that can cause this. If it brews without the portafilter in, then your coffees is too fine or you have a blockage in your basket if it has a ring in the bottom. You can clean the basket by using espresso machine cleaner like Cafiza or JoeGlo. Automatic dishwashing detergent works in a pinch also. 1/4 teaspoon in the basket then brew like normal but stop after 3-5 seconds and let set for 1 minute. Repeat this for about 5 - 10 brews then rinse the basket and run 2 - 3 long shots of just water through the basket (brew) to thourghly rinse the basket.
If it doesn't brew with out the portafilter in, then you have a blockage in your brew head. There is a screw that holds in the dispersion screen. Above that is a larger screw that holds in a check valve. if you can get the check valve out see if water will run through. If not your blockage is in this tube. run a heavy wire up this tube for about 4 inches. Twist the wire as you go. Test to see if you can get water through. If so reassemble and do a descale through both the wand and brew head. Use a strong descale the first time and then do a second. Descale 2 to 3 time a year to prevent this.

Water is dripping out the side of the porta filter


You will have to replace the group gasket, you can also try using a group brush to clean any coffee grounds up there, but you will most likely have to replace the group gasket.

My Gaggia Carrezza is pulling the shot way to quick.


Of all of the gaggia machines I have worked on I have mostly seen clogged filter screens in the top of the brewing head. I am not familiar with your particular machine but look in the top above where the coffee goes and see if you see a shower screen up there. If so, the screen maybe clogged with coffee residue and stopping the proper flow of water through the coffee. Clean out any and all water ports and screens and around the rubber seal gasket where the coffee holding cup seat at the top of the chamber. Onthe commercial gaggias I worked on I used to take out the screen and hold it over the open flame of a stove burner and burn it clean rinse it with water to cool it. scrub it well and then put it back in the unit. Run a cycle with water only to check the flow and finish cleaning it out, let it get back up to temperature and then brew a cup and see how it does. Good Luck
