Milk steamer not working

Question edited for typos and spelling. It is a 'frother' rather than a 'throther'.

The roaring is normal, you are releasing steam from a boiler. Steam wand issues are usually caused by cooked milk solids inside the wand. You need a good enzyme cleaner like Rinza. Help and videos in the link

Here are some possible reasons why the milk steamer flow is diminished and steam is not coming out of the bottom of the machine:

Clogged steam wand: The steam wand might be clogged with milk residue, which can restrict the flow of steam. Try cleaning the steam wand with a damp cloth or a pipe cleaner.

Faulty steam valve: The steam valve might be faulty or damaged, which can cause a decrease in steam pressure. In this case, you may need to replace the valve.

Blocked milk frother: The milk frother might be blocked with milk residue, which can prevent the milk from frothing properly. Try cleaning the milk frother with a damp cloth or a pipe cleaner.

Faulty milk frother: The milk frother might be faulty or damaged, which can cause a decrease in milk flow and prevent proper frothing. In this case, you may need to replace the milk frother.

If none of these solutions work, it's best to contact DeLonghi's customer service for further assistance

This forum talks about your problem and has several reasons for the vibration.

I'm guessing this is a table top machine. If so then I take your meaning of "Blowing Off" as in turning off or running out of steam. The table top steamers usually found on home units do not have the capacity to froth large mugs like a "Venti" 20 oz cups. You will have to wait for the boiler to re-heat. It's best to heat a smaller cup of cold milk, pour the milk into the venti and make a 2nd batch again with cold milk. (It's hard to re-froth hot milk).
* check your steam wand tip if it's plugged with old milk. Soaking the wand in warm water overnite will help soften the milk which can be blow out when you make steam again. If you make a lot of milk drinks, it's a good idea to give the wand a blast of steam, then a good wipe with a damp cloth to keep milk residue off the wand.
* It's also possible your steam heater is starting to clog up. If you find that it gets slower and less steam with time then the steamer will need to be replaced. Check your warranty and call for service.
* Please update question with brand and model if you want more help.

90% of all my service calls were due to machines that were not cleaned DAILY. About a third of those were for espresso machines with a steamer and the rest for auto frothers. Most Barista's don't use auto frothers as they have very little control over the frothed milk. (Heat, froth density, firmness, holding, etc.) Milk(any type) will clog a machine in minutes if not cleaned up after use. Spoiled milk will contaminate any product with curds and have a bad smell to coffee.
* Clean up after any milk usage. Seconds count after frothing milk with a steam wand. Get workers in the habit of removing milk pitcher from wand and give the wand a short blast to flush the wand and wipe with a damp towel (tower wash and sanitized often) Leave the folded (quartered fold) next to wand on drain tray where it's always handy.) It only takes seconds to perform and customers appreciate the cleanliness and professional look.
* take a tip from Bartender's; you HAVE TO WASH WITH DETERGENT! when washing glasses that had milk drinks in them. Nobody want's a sour milk smell in any drink. Milk film can only be removed with soap and water and a brush. That's why you see automatic cup washers on every bar set up. It does take elbow grease to get these cups clean.
* Harden, cooked milk (coffee to) is best soaked in clean water (detergent optional) and let it sit over nite. This is a good practice to keep everything coffee/milk stain free as everything is washed/rinsed prior to use in the morning.
* Really, really baked on coffee (left burning on warmer for several days, weeks. Will need an urn cleaner to soak and wash out several times. Check with your coffee vendor as most will just swap them out with clean ones. Otherwise ask for urn cleaner from them and follow instructions. Hot water with a tablespoon of urn cleaner for each pot and let soak over nite. wash and rinse thoroughly prior to use.

Take off the end bit; it unscrews. Poke a needle through the hole; I find it gets blocked quite regularly. While it's disconnected turn the knob on the right. Steam should come out. If it doesn't there is a blockage inside the machine and you need to get inside it to fix it. But the only blockage I've had is in the end bit.

I've also had this problem with the Krups 'Il Primo' - reduced steam for frothing of milk but plenty of espresso.
Diagnosis: over many uses, a residue of dried milk plugs the interior of the steamer tip.
Fix: Using a small adjustable wrench, remove the tip. Clean it inside and out with a tooth pick. Reattach the tip - gentle with the wrench.

My XP5240 also started blowing the steamer wand off after about 3 months of use, despite fiollowing the Krups cleaning instructions. Here's what I did to fix it.

A: The Problems.
The wand has three holes in the coffee end (center, and on each side). The center hole gets blocked with milk residue. This causes a pressure build up in the wand assembly, and eventually this is enough pressure to overcome the three gripping clips that hold the wand to the nozzle tube. I suspect this was an intentional design for safety. It's unfortunate that it also sprays the user with milk when it lets go.

The second problem is that removing the wand requires that the outer clip retainer ring to be slid down to release the clips. Many users don't realize this and try to pry or twist the wand off. This breaks the clips.

B: The Solution
The wand has to be regularly and throughly cleaned. Just soaking it is not enough. Do it this way:

1. Slide the clip retainer ring down, and then hold the steam tube and gently move the wand straight down. DO NOT try to twist the wand to one side, or you WILL break the clips.

2. Holding the ring, unscrew the coffee nozzle end. The wand separates into three parts: Outer tube, inner steam tube and decorative cylinder.

3. Use a needle or very fine wire (approx 0.4mm) to clear the three holes in the coffee end nozzle.

4. You now need to clear the metal wand tube of milk residue. I found that a 7/64" drill bit was perfect to do this, as it fits snugly in the tube. The amount of gunk removed was surprising.

5. Blow the tube clear from both ends. If it's clean, you will be able to see light through all three holes. If not, go back to step #3.

6. Make sure that there is no milk residue on the steamer tube nozzle where the wand clips on. Milk contains fat, and this is an unwanted lubricant.

After cleaning, my steamer works properly for several days. I also located a 21mm ID O-ring at the local hardware store to hook over the clips. This provides a bit more clip gripping pressure, but will still allow the wand to come off should steam pressure gets excessive.

First,I'm NOT a Breville tech, but this is a very common problem with steam boilers. Your valve seal(s) are worn and needs replacement. Any leaking water or steaming from various places other than the steam tip is causing your tank to lose pressure. The heater needs to stay on longer just to keep everything up to pressure and properly heated. You probably noticed that your shots may not have the creme or very thin and watery. Milk steaming takes a long time or not enough steam to complete a froth, especially on a Latte. Your machine needs servicing. Contact your vendor or MFR for service.
** loose steam wands will fall off and be re-assembled without the ball seal or washer. Look around the machine for a round disk made of hard rubber or nylon plastic. Take apart the wand and reassemble with the washer or get a new washer and tighten,.
** other places were you can loose steam pressure is the Anti-siphon valve, Safety valve, and various pipe fittings to the steam boiler. Look for steaming plumes from unexpected areas of the machine.
** Scale that has built up to the point of causing valve problems are usually too much for DE-scaling to work properly. Usually done as a preventive maintenance rather an alternate to repair. Like a blood clot, if you remove it while still in an active system. Where does this clog end up? This debris needs to be physically removed from the pipes, valves, and/or tank. Heavy scaling is a sign of an old machine that will need a lot of servicing to bring it up to MFR specifications.
** Final; The steam wand(s) are the most used (and abused) parts of the machine. Constant cleaning is a required task that needs very diligent baristas to keep it fully functional. I've found that best operators use the following method to keep the steam wand in top condition; Remove milk froth pitcher completely from wand, Send a short blast of steam to clear milk residue from tip. Take a damp towel to grab wand an pull downward to wipe off any remaining milk residue. Leave the wand in a pitcher of cool water to soak during long break periods to help break up any dried milk. Let soak over nite when not in use. Have your operators notify you of any 'loosey-goosey" wands. Tighten them properly but make sure all the parts and washers are there. Check your manual or just ask your technician to show you the next time.

The frother does not have a vacuum, it uses venturi pressure to draw up milk through a venturi at the top of the steam feed. The milk side is clogged from not cleaning enough. soak in boiling water for a few minutes and try to run it in steam mode for a while... if that doesnt work, a light lye solution will dissolve the milk residue clogging it. neutralize the lye with vinegar drawn through after the clog is gone.

(lye will dissolve you as well as milk... use gloves and don't put your face near it while it's working.)
