Espresso part not working, even without coffee. Not building enough pressure?
Question edited for funky spelling of Iv'e rather than I've a contraction of 'I have', the apostrophe replaces the letters 'ha'.
By your own diagnostics the nozzle itself is blocked. Look inside for a filter matrix that gives the 'Crema'.
Although you don't mention make and model (all questions need that), typically these machines need dealer service every 12 to 18 months in a home setting. Of course they don't tell you this when you buy them. In a commercial setting, my coffee machines were serviced in house every month. One machine did a thousand cups a day!
Coffee beans grind but water comes out clear. No coffee.
When a grinder is jammed, generally the motor won't be able to spin the burrs to grind the beans. This can happen for a couple of reasons: coffee oils and debris can easily build up in the burrs if they have been left to collect over time.

Miele CVA4075 steam system doesn't work properly
Since you've checked and replaced several components, and the issue persists, it's possible that there might be a more complex underlying problem. Here are a few additional things you could consider:
- Pressure and Flow Sensors: The steam system might have pressure and flow sensors that regulate the steam output. If these sensors are malfunctioning or not providing accurate readings, it could cause the behavior you're experiencing. Check if there are any sensors related to steam output and ensure they are functioning correctly.
- Electrical Connections and Wiring: Inspect all the electrical connections and wiring related to the steam system, including the sensors, solenoid valves, and pump. Loose or damaged connections can lead to inconsistent performance.
- Control Board: The control board that manages the steam system's operation could be faulty or not functioning as intended. If you've ruled out all other possibilities, it might be worth considering the control board as a potential source of the issue.
- Calcium Buildup: Even though you've mentioned that everything is clean, there might still be some calcium buildup in parts of the system that are affecting its operation. Consider running a descaling solution through the system to ensure all components are free from any mineral deposits.
- Consult Professional Technician: At this point, given the complexity of the issue and the components you've already checked and replaced, it might be beneficial to consult a professional technician who specializes in Miele appliances. They might have specialized tools and expertise to diagnose and repair the issue accurately.
Remember that working on complex appliances like the Miele CVA4075 requires technical expertise, and it's important to prioritize safety. If you're not comfortable with certain troubleshooting steps or if the issue remains unresolved, seeking professional assistance is recommended.
Ranchilio Silvia steam not working..
If you're experiencing issues with the steam function on your Rancilio Silvia espresso machine, such as low steam pressure or no steam at all, there are a few possible causes and troubleshooting steps you can take to address the problem:
- Check Water Level: Make sure the water reservoir is filled with water to an appropriate level. The steam function requires sufficient water to generate steam.
- Purge Air from Boiler: If you're getting low air with no pressure from the steam wand, it's possible that there's air trapped in the boiler. You can try "purging" the air by turning on the steam wand and letting water flow through it until a steady stream of water comes out. This might help remove air pockets from the system.
- Steam Wand Blockage: The steam wand could be partially blocked by milk residue or mineral deposits. Clean the steam wand thoroughly using a steam wand brush and ensure that the tip is clear.
- Vent Valve: The vent valve on the top of the steam wand might be clogged. Try removing the valve and cleaning it to ensure proper steam flow.
- Boiler Pressure: Low steam pressure could be a result of inadequate boiler pressure. Check the pressure gauge on the machine to ensure that the boiler pressure is within the recommended range. If the pressure is too low, you might need to adjust the pressure settings (if your machine allows for it) or seek professional assistance.
- Steam Valve: The steam valve might be worn or malfunctioning, preventing proper steam flow. If the steam valve is not functioning as it should, it might need to be repaired or replaced.
- Boiler Heating Element: If the heating element in the boiler is not functioning correctly, it could lead to low steam pressure. Check for any signs of damage or malfunction in the heating element.
- Professional Service: If none of the above steps resolve the issue, it might be best to seek the assistance of a professional espresso machine technician. They can diagnose the problem accurately and perform any necessary repairs.
Remember that working on espresso machines involves potentially hazardous components and high-pressure systems. If you're not comfortable with any of the steps or if the issue seems complex, seeking professional assistance is recommended to ensure your safety and prevent further damage to the machine.
Saeco Brew Unit: How to realign the gear?
Saeco XSmall : Cannot put brew group back in... Turns out the drive gear in the main machine is mis-aligned. This can happen if you try to remove trays or open the service door while the machine has not "finished" a brewing cycle (coffee may be done, but the machine is not!). Confirm this by looking at the drive shaft. It has 5 splines, and two are much wider than the other 3. Those wider ones should be on the top--if they are in any other position, then it does not match the "neutral" position in the brew group and the brew group cannot be inserted. Unless there is something else wrong, the machine will re-align itself during the power-on self-check, but in order to trigger the self-check, you have to fool it into thinking that all the trays, etc. are installed (essentially, bypass all relevant microswitches). This doc has some details and pictures of what to look for: https://www.coffeetico.com/SAECO_pdf_files/BrewGroupRemoval.pdf. For the XSmall, leave the brew group out, shut the service door and put the grounds bin in. Also, make sure the water bin and drip tray are in as normal. This is enough for the XSmall to startup. Turn the machine on and as it does its self-check, the gears get re-aligned properly. It will eventually figure out the brew group is missing and start flashing red--turn the machine off at that point. Verify that the two wide splines are at the top. The brew group should now slide in easily.
