I am having problems with the coffee dose adjuster - it seems to be stuck, as it will not move the whole rotation of the adjustment area. It is stuck at the 3rd dot on the left - while this makes a fine short espresso, the longer 3 levels are "cut off" as it stops at the coffee level and cannot reach the last 3 settings.
It as almost if the adjustment wheel feel off and was replaced back improperly, but this is not the case. It worked fine for about a week and got stuck after that. I have, after it got stuck, tried to take off the plastic wheel cover and see if it were just off it's axis but it is competely fine, there is something in the wheel mechanics themselves that is stuck.

Continuous water flow indicates a stuck valve. These suggestions may help depending on type of machine:
Full Automatic (Super Automatic); Valve needs back flushing, cleaning, or replacement. There is an off chance the dose needs re-programing.
Semi-Automatic; Valve needs back flushing, cleaning, or replacement. Check programing for dose.
Manual; Most manual espresso machines require operator to stop dose. (By releasing dose button or lever)
Arm style Manual "Jaw Breaker"; These are physically chambered dose which are unable to constant dose. Bad seals needs replacement (if you can still find them)
final comment to this 'open' question; All coffee machines needs periodic cleaning. Most espresso machines needs back flushing (not to be confused with de-scaling.) Usually a cleaning tablet or powder is poured into dose chamber (or back flush portafilter) and cleaning cycle or long dose is performed. This cleaner will loosen baked in coffee and push it out the pressure relief pipe. The machine will need to go into a normal dose cycle without coffee to flush the cleaner out of the valve and dosing system. Do this several times. Good daily cleaning habits will keep your machine in top condition.
Removal Step-1: Remove beans that are in the bean hopper without spilling them inside. (Use Vacuum). Step-2: Remove the beans container by removing 3 phillips head screws. Remove the rubber gasket from below the hopper. At this stage the upper burr will be visible. Step-3: Rotate counter-clockwise the outer ring of the grinder assembly (the ring has gears half way around), until the red mark is at the 9 o’clock position, looking at it from the front of the machine. Step-4: Lift the upper burr by using the fins that are on top. Press lightly on the doser adjustment gear, to clear it from the dose adjustment gear. Cleaning- At this stage, the grinding chamber will be exposed. Clean out any crushed coffee in the grinder chamber and the burrs. Use Vacuum and cleaning brush. To Re-Assemble Step-1: With the red mark on the outer ring still at the 9 o’clock position, replace the upper burr back into the grinder. Make sure that the red line (on the upper burr) is at the 3 o’clock position. This position will align the other tabs as well. During re-installation, press slightly on the doser adjustment gear so the upper burr will clear it as it is placed back in. Step-2: With the Upper burr in place, rotate the outer ring clockwise until it stops. The two red marks should be aligned at the 3 o’clock position underneath the doser adjustment gear. Step-3: Replace the soft rubber gasket back on the upper burr. Use the fins to align it properly. Step-4: Slide the doser adjustment gear toward the front of the machine until it stops. Step-5: Before replacing the bean hopper, rotate the grinder adjustment wheel to Zero (0), and the doser adjustment wheel to Minus symbol (-). Place the bean hopper into position on the machine, slightly adjusting each adjustment wheel as you are placing it down in the machine. Once in place, fasten the bean container with the 3 screws. Test each adjustment wheel through the full range of motion. The grinder knob rotates from 0 to 18 and back, and doser knob from Minus (-) to Plus (+) and back. Now position the grinder adjustment knob at Eight (8) and the doser adjustment knob to the halfway point between the Plus (+) and the Minus (-) marks. This will put the machine back to the factory setting. When using for the first time after adjusting the grinder, it may take more than one grinding cycles to make the first cup of coffee.
Does it sound like it is trying to grind or is it silent? Listen carefully after pressing the coffee button. If it is silent then the motor has most likely died or the thermal fuse on the motor has blown due to motor overload and overheating. If you can hear a faint humming, then the grinder may just be blocked (or the dosing chamber located between grinder and brew unit (above brew unit) may be blocked). First try backing off the grind to the coarsest setting. Even if you can't hear the motor, it is worth backing off the grind anyway (easy to do) as you may be lucky. To clear doser, remove brew unit and look up. You shold see a curved trap door like thing that you can swing up to release or poke out stuck ground coffee. If the machine instantly makes that 'tuka tuka' sound after hitting the coffee button (like it does when it is dumping the coffee after grinding) then the flap or micro switch in the dosing chamber is stuck. Move the dose (grind quantity) adjustment lever back and forth a few times. If these suggestions don't help then take it to an authorised or expert repairer.
I had the same problem.
Check and make sure your dose is not turned up too highor your grind is not set too fine? Turning the dose knob clockwise decreasesit. I have ended up with my grind set on 13 which is more coarse than averagefor the beans I'm currently using. Adjust the grind while the grinder isworking by one number and then brew 3 or 4 coffees before changing it again. Ittakes that long for the grind to be seen in the coffee. The higher the number,the coarser the grind will be. Any time you use different beans it is possiblethat you'll have to reset the grind.
You can change the coffee dose that you put in each cup by lifting the cover on the bean hopper (where you put beans), turn the dose knob (small knob closest to front of machine) clockwise to decrease the amount of coffee used for each cup. Set the knob and then press the coffee button. Gradually decrease the dose until you find the taste you like.
Hi,..These saeco models have a auto adjusting grinder. If the brewunit is heavy or in other words overloading, the machine will reduce the grinding time lesser to produce less ground coffee.If it senses the brewunit is smooth and light in loading (compressing the grounds), it will increase the grinding until it reaches the optimum dose. So it is important to clean and lubricate the brew unit at all times. Hope it will solve the problem. Good luck.
Well, when you set it that low it allows the water to pass very quickly and if the water passes very quickly there may not be sufficient time to absorb the coffee; hence weak coffee. The setting should be reset to the middle, at 10, and tried again. Then, if you want to change it move it only one or two numbers for enough cups to see if there is any change before you move it a large number. Going higher or lower makes it pass more or less quickly with results accordingly.
You may also have the dose set too low and you may want to set it higher increasing the amount of coffee in each dose.
Then again, since it was used, you don't know if the machine was taken apart by someone who reinstalled the machine with the dials you are using out of whack with where they should be set.
