fill the tank with detergent and let the hot water run for about 15 seconds. Then turn off the machine for about 15 minutes. Then turn the machine back and let the hot water. Then rinse the water tank and fill it with clean water. Run hot water again to empty the tank. Fill clean water again and then you can put down coffee :)
Sounds like the the shower screen under the red o-ring in the brew group needs to be cleaned, you can remove the screen and clean or you can purchase some espresso machine soap puro caff or puly caff, and run it through the brew group using the preground method the clean out coffee oils.
The problem is a very frequent one a small scale part have been moved and it stack to the water steam valve and it blocking it from closing completely. So when you make coffee the hose of water for coffee is in parallel with hot water steam wand and since the valve remains partially opened the water for coffee find easy escape from steam wand.
So we suggest to perform one more descale and it may need twice hopefully this small scale part to be dissolve a little bit more in order to pass thought the steam valve and thus the valve can close again completely. If you are not so lucky the part remain on the valve then only solution is to disassemble the machine thus clean the steam valve manually. In this solution you may find out that the valve o ring might be damage and thus the leak.
here is the link with steam valve parts and this the parts diagram of the machine and here many more for your machine
That is serious, that means the grinder is jammed or not working. To check the components of the machine follow these instructions.
Press and hold the steam button and turn on the machine, when you see the lights going around in anticlockwise direction, release the button. Turn the coffee dial to the left and press the steam button, the grinder should turn. Dial on the right and pressing coffee ****. water pump runs. Press steam ****. brew group go up, dial 1/4 to left B/Group down.
If grinder not turning the motor is bad. Hope it will help to find out.
Descaling or boiler problem doesn't seem to be your issue as your single boiler is both used to make hot water and coffee. As the hot water is working fine we should concentrate on the brewer unit blockage ( give it a good clean and remove Brewer screen or screens and un block dirty clogged holes ). Then if problem still exists make sure you are not grinding your coffee too thin ( will cause blockage and machine lockup ) if this is the case. I have also come across customers who for some strange reason turned off their machines before it could finish the coffee dumping cycle and leaving it for a while ( left over coffee goes hard and cloggs ). Hope this helps.
Sounds like your coffee grinder is grinding too fine. I would up the size of your grinder. The larger the numbers the coarser the grinds. Also, should descale the machine if you haven't in a while. One of these two things may help.
Switch off the machine.
Pour a descaling product into the water tank.
Switch the machine on to the programming mode(see below). Place a large container under the steam/hot water dispensing tube and open the steam/hot water knob slowly, turning it counterclockwise.
Turn on the machine by pressing the main switch and let the descaling product flow out of the dispensing tube for approx. 1 min.
Close the knob again.
Turn off the machine with the main switch and let the solution take effect for approx. 5 minutes.
Repeat this procedure two or three times, to allow all of the descaling product in the water tank to flow out of the dispensing tube.
As soon as descaling has been carried out, rinse the tank thoroughly and fill it with fresh water.
Switch on the machine and let fresh water (approx. 2 l) flow out of the steam/hot water dispensing tube in order to rinse away residue.
The machine is now ready for operation.
When the machine is on, the warning light switches off automatically, by pressing the steam selection button for at least 5 seconds.
To enter the programming mode, turn the machine
off with the main switch.
Press steam , espresso coffee and the
main switch at the same time.
