Question about La Pavoni "PROFESSIONAL Chrome" 16Cup
I have a europiccolo and gradually the water has run more and more slowly. I now have to force the lever up to get water to run through.
Previously once the lever was raised it would stay there until the coffee started running through in about 5-10 seconds
Is there an adjustment to fix this? (I have tried varying the grind etc and that didn't help)
Most probably the plunger has unscrewed. You need to remove the plunger from inside. Remove the bottom circlip and remove that pin so that will be disconnected from the plunger mechanism. Remove the bolt and washer on top of the plunger, remove the group and than smartly tap with a rubber mallet to remove the plunger mechanism from below. You will probably notice that the shaft is unscrewed from the ceramic plunger though not all the way. Tighten this and clean inside the group. replace the mechanism from below and replace the sieve with the rubber o-ring seal - you will have to use a screwdriver or similar implement to secure the o-ring in the space. Replace the pin for the handle insert the circlip and replace washer and bolt. You are good to go.

That is most likely the issue & answer as described by rajuraja. For a quick, temporary fix—remove the lever pin that goes through the piston pin and then with a wrench, carefully turn the piston clockwise maybe 2 or 3 full turns. Be careful not to scratch the chrome on the grouphead. I turn and simultaneously lift at the same time. This keeps me going for several days, until the piston gradually unscrews itself. Put a couple of drops of PLA Turbo-Lock High Temperature Thread Lock on the threads of the piston if you decide to take the entire unit apart. Available at orphanespresso.com

Hot water pressure relief valves serve two functions. The first is to remove high-pressure water from the hot water tank. The second function is to act as a high temperature valve to remove water that exceeds a predetermined point for the valve. Both of these relief settings are preset at the valve factory. Many pressure relief valves will come with a metal tag that identifies these release points. If you're attempting to remove the hot water heater pressure relief valve, pay careful attention to ensure that you replace with the correct valve.
Your hot water heater has a pressure relief valve safety mechanism. When pressure inside the water tank exceeds certain limitations, the valve opens up to allow the pressure to be released. A faulty pressure relief valve will not release excess pressure, which could cause extensive damage to your home. You should test the hot water heater pressure relief valve once every six months to ensure proper operation. If the pressure relief valve fails the test, replace the valve with a new one immediately
Locate the pressure relief valve on your hot water heater. The pressure relief valve has a lever handle on top with a drain pipe attached to it. The pressure relief valve is most often on the side of the water tank toward the top. Newer models of hot water heaters have the pressure relief valve on top of the water tank.
Inspect the area around the pressure relief valve for signs of leaking water. If there is leaking water near the relief valve connection, replace the relief valve. If no leaking is evident, proceed with testing the pressure valve.
Examine the area below the pressure relief valve drain pipe. Most water heater closets either have a drain in the floor below the pipe or the pipe is inserted into another pipe to direct the water out of the home. If the end of your drain pipe is not in another pipe or there is no drain in the floor, place a bucket under the drain pipe to catch water when you test the pressure relief valve.
Pull the lever handle on the top of the pressure relief valve up with your fingers. A working lever will lift up without difficulty.You should begin to hear water going through the drain pipe. Slowly release the lever to shut off the pressure relief valve. The pressure relief valve is good. If you did not hear water running through the drain pipe, lower the lever on the pressure relief valve and replace the valve. If the lever is difficult to raise, do not force the lever. Replace the pressure relief valve.
