Suddenly my esam 4400 does not give the milk to make cappucino although I have cleaned everything very carefully. what can be the problem?

Based on the information provided, it is possible that there is an issue with the machine's internal circuitry or wiring. It could also be a problem with the control board or the sensors that detect the presence of the milk jug or hot water spout.

One possible solution is to try resetting the machine to its default settings. To do this, turn off the machine and unplug it from the power source. Wait for a few minutes before plugging it back in and turning it on again. This may help reset any internal settings that could be causing the issue.

If resetting the machine does not work, it may be necessary to have it serviced by a professional technician. They can diagnose and repair any underlying issues with the machine's components.

It is also worth noting that regular maintenance and cleaning of the milk frother and hot water spout can help prevent issues from occurring in the first place. Be sure to follow the manufacturer's instructions for cleaning and descaling these parts of the machine.

Overall, if the issue persists, it is recommended to contact Delonghi customer support or a certified technician for further assistance.

Here is the manual:

Two causes from the troubleshooting section:
The froth regulator is incorrectly adjusted. • Adjust following the instructions in the section on preparing drinks with milk.

The milk container lid is dirty. • Clean the milkcontainer lidasdescribedin the section "Cleaning the milk container".

Try filling both water and the milk container with the correct decalcifying solution - just slit the 500 ml that results from the 1:1 mixture and - without the coffee capsule - press the cappucino button. Instead of cappucino you will get the decalcifying solution running through the entire system including the connector for the milk container (unlike the recommended decalcification method where you use the extra nozzle). Good luck - worked for my machine which only produced steam but no milkfoam...

This is factory preset and cannot be altered. You do need to use the "clean" function on the milk frother unit to ensure the boiler and pipes heat up enough also.

This is preset and cannot be altered.. Do ensure you preheat the milk frother before use.. by activating the "clean" button on the frother jug

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.

Possibly all you need is to clean off the bar code reader window. It's right under where the bar code on the t-disc ends up. A little dried milk, etc., can cause your symptom.

Does the steam itself smell, or just the milk. If yes on the steam run the descale again. If no on steam then check the perfect cream wand the black plastic arm connected to the steam wand, dissamble and clean, make sure all the holes are clear.

prime the machine they give a little pump in the kit remoe water tank fill pump insert it in the hole apply pressure it should prime itself try opening the side valve to vent the machine let me now pierre
