Any good suggestions for ways to clear what appears to be a blocked steamer tube - the bit on the side of the espresso maker used to heat liquids. I cant seem to get it to steam at all. pressure builds up no problem - steam is generated but it just wont pass out the steamer tube. I've had the tube off

Re: blocked steamer outlet /frother tube

Boil white vinegar in the unit. If the tube isn't completely blocked, the acid steam will clear it. If (after boiling the vinegar) it doesn't open up, then use wire pipe cleaners soaked in hot vinegar to slowly "****" it out, dissolving the calcification as you go. Pre-soaking the tube in hot vinegar will help. If you can remove the tube and lay it down in a kitchen pan, then boil it in vinegar. Once cleared, make sure to boil vinegar in the unit and eject the steam through the tube on a regular basis, at least once every 2-3 months, to keep the scale deposits down.

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.
Had this exact problem a few times on a cleaned well maintained milk jug top with an ESAM5500M. Delonghi 'repaired' it by sending a new milk jug frothing top.
It's caused by milk fat deposits, the frother part on the milk jug may look clean but deep inside it's not. I clean mine with pipe cleaners, detergent and hot water and still it wouldn't froth.
The problem re-occurs for me every 6 months or so. You could buy the milk fat remover solution to clean it. Personally I just boil the whole milk jug frother in detergent and the again in descaling solution, that's fixed this problem twice now, although I think it will eventually corrode the 'o' rings on the frother, still cheaper than buying a new frother part each time though.
If it still doesn't work after that, the only other reason for this problem I found mention of was caused by a broken rubber seal where the milk jug fits to the machine. It's most likely to be milk fat deposits inside the frother though.
Most common cause of this problem is a blockage in the milk jug. First thing you should try is soaking the complete jug top in a quality milk line cleaner (available from specialist coffee machine retailers) for at least an hour and then rinse thoroughly. Then try running a fresh cleaning solution through the jug instaed of milk. Good luck and post again if this doesnt work.
1. Remove the froth enhancer and rinse under warm tap water. 2.. Wipe the steam wand with a damp cloth. 3. Briefly set the Selector Control to the ‘STEAM’ position to clear any remaining milk from the steam wand. If that doesn't work, remove any rubber parts. Place the metal frother tube in a pot of water with a bit of ammonia or vinegar in it. Heat the water to boiling, then let it simmer awhile.
The "frother" is probably blocked. Remove it and see if you can blow through it. If not, you can try cleaning it with a paper clip. If that won't work, place the metal frother tube in a pot of water with a bit of ammonia or vinegar in it. Heat the water to boiling, then let it simmer awhile. After it cools, try using the paper clip again. You should clean the steamer attachment after each use: 2. Remove the froth enhancer and rinseunder warm tap water.3.

A properly clear outlet pipe should be able to cope with the output of a washing machine. If not it is partially blocked. try hooking the outlet pipe over the side of the laundry sink, If this works......leave it that way until you figure out who is going to unblock the outlet pipe.
Try this:1. Pour in vinegar instead of water. 2. Bring vinegar to a boil but do not run it through the machine. 3. Turn off machine for about an hour. 4. Remove sheath from the frother and clean the metal tip. 5. Place tip of frother into large mug of cold water. 6. Turn espresso machine on and allow vinegar to run through frother. 7. You'll know the frother is clear when the water in the mug begins to churn rapidly (and perhaps loudly). It may take the vinegar a little while to dissolve and loosen the blockage. If the process does not work the first time time, try again later and allow the warm vinegar to sit in the machine longer.
Optional: Before starting the process, unbend a paperclip or thin metal hook (the kind used for hanging holiday ornaments) and use it to clear the steamer orifice.
To keep frother clear: Follow recommended descaling schedule in user manual
Both tubes must be in the water. If you haven't used the machine for awhile, fill the water canister, turn the espresso maker on and also turn on the delivery switch (the top switch on the EC140). You'll hear the pump and in a second or two water will begin to exit the boiler nozzle. Immediately turn the delivery switch off. Wait for the "OK" light to come on. Press the "Steam" switch (the middle switch on the EC140, place an empty cup under the frother and turn the steam control knob on top in the counterclockwise direction. Steam will come from the frother. Be very careful to avoid contact with this steam.
