Coffee stops flowing
Run a 50/ 50 vinegar & distilled water solution through it. Only use distilled or bottled, purified drinking water from now on.
I have very little pressure when making an
I had that problem once when I ground my coffee too fine? Perhaps your grounds are too fine or your packing too much in. Try a bit courser grind and maybe not so much and not stamp it too hard? Hope that works!
I have a delonghi EC701
First, I'm not a delonghi technician. But I've worked on similar units.
* Table top brewers usually have water reservoirs that require monitoring and refilled when they get low (especially after brewing)
* It's possible the water level sensor is stuck (in the water reservoir) which tells the machine that it still has water and keeps heating the tank(s). Clean tank as described in your manual. You will still need servicing to check and replace fuse(s).
* There is usually two tanks/heaters in this type of table top machine (larger pro models use one large tank) The thermal limit fuse on one or both are probably blown. Call vendor for service.
* Did you change water source? Since this is a table top machine in which you fill the water tank. Try to use filtered (bottled ok) water. Do Not use Distilled or 100% pure water as this type of water will eat out the metals from your machine! Some places use a water softener as it tends to be better for the machine long term (years).
* Still got problems? Check with vendor or MFR for service or replacement. Most machines of this type do not have serviceable parts or adjustments.

first perform a chemical cleaning, place the chemical in the water tank and then this hot place to make coffee, so that the chemical clean pump and piping hot water, repeat this until you spend all the water,

if you have an ohmmeter, disconnect the cables that feed the resistance and connects the ends of the meter should give a value of element 5 to 30 ohm, if you give infinite that is very high due replacement it, there are also two thermostats one limit and a control, if you use this meter their connections resistance removing the cables connecting them, the measurement should be 0, if it gives you another value or infinite must change.
New out of the box. won't dispence water to
Hi. Is your pump working. Should be able to hear it. If its making a really loud noise then it could be an air lock in the line. Try using the hot water button to bleed the system. Also see if it will despence water wiyhout any coffee in handle. Dazza REPAIRER
I have ran hot vinegar water through, it sounds like it is laboring to "bring the water up" is the sound.. it takes a long time & it seems not enough pressure to force water through the coffee.
Could be several things.
- In the bottom of the water tank is a spring loaded "valve" that may be stuck shut. It is much more common for it to be stuck open.
- There is a filter in the suction line to the pump. There is a chance that the hot vinegar loosened something that is now plugging the filter.
- The hot vinegar may have damaged the pump. Cold vinegar may have been a better cleaning fluid. (A cold citric acid solution seems to be popular too now days.)
- If the relief valve was lifted (opened) during this procedure, it is possible that it is not seating tightly.
If this was my machine, I would replace the filter and pump because they are the most likely items to be a problem. It is not a hard job but one does have to be patient and careful. I would take a picture every time I removed something just to be sure I got it back together right.
I've included a link to a part supplier part diagram. You can see the pump and filter.
Good luck.
