How do i undoit -stuck

If the infuser on your DeLonghi Dynamica espresso machine is stuck, there are a few things you can try to release it:

1. Turn off the machine and unplug it from the power source.
2. Wait a few minutes to allow the machine to cool down.
3. Press the infuser release button while gently pulling on the infuser.
4. If that doesn't work, try gently pushing the infuser up and down while pressing the release button.
5. If the infuser still won't budge, try applying some food-grade lubricant to the infuser and/or the infuser chamber.
6. If none of these steps work, it's best to contact DeLonghi customer support or take the machine to a professional repair shop.

Switch the machine off, AND pull the plug, wait 5 minutes (to be sure) and turn it on. Then turn it off again, now the infuser should return to it's normal position where you can take it out.
If the descale button is still flashing, try descaling again. Was the procedure interupted before? That would be a reason the light keeps flashing.

make sure you are trying to remove the infuser when the machine is turned off. you can damage the unit if trying to remove the infuser while the machine is on (and you won't be able to get it out).

your inlet solonoid is staying open,valve is stuck open or the coil on valve is defective or if machine uses a lvl board the probe or board might be gone.

Put back together, turn on the machine, then turn of the machine with the power button on the machine, then turn of the power point, should be back in place to push in both red buttons, enjoy your working machine and coffee, cant find an answer for my issue
