SOURCE: Grimac ZOLA II - NO HOT WATER !!!

The problem is either the switch that controls the solenoid for the hot water valve, or the solenoid itself. Place finger on the solenoid coil and press switch if the solenoid is working you will feel the nucleus when it engages. If both switch and solenoid are working then the pipe connected to the solenoid from the boiler is clogged.

SOURCE: grouphead not dispensing water

Remove the shower screen and press button to brew, if water flows the the holes in the screw/diffuser is blocked, if water does not flow then the blockage is at the solenoid or within the group head chamber. This problem I have notice when someone brewed without the shower and screw in place.

Gaggia Baby filter is stuck!


The filter is stuck on the group head of the machine only by the force of dry coffee which acts like glou and since on the portafilter is secure by a wire spring which is probably loose and couldent hold the filter in place.
So all you need is a pointing screwdriver with edge like a nail or similar and use it on the filter try to level it out and by a little force try to move it and get unstuck. After that you can clean also the coffee remaining's on group head also.
In order to avoid this in future you will have to clean the portafilter from machine after you will make a coffee, replace the portafilter spring with a new one and clean the grouhead and grouphead gasket often with grouphead brush. You may need also to buy cleaning grouphead powder and backwash blid filter to perform backwash frequent. All these cleaning and parts you can easily find in eBay.

I have a Rancilio Classe 10 Espresso Machine and the water is flowing unevenly between groups. The difference between shots is 11 seconds to 27 seconds. I have backflushed each group and replaced both...


It could be the metering jets in the grouphead and or flowmeters. Try pressing both buttons at the same time to see if they give you the same volume and time.

Ascaso Dream Leaking Water


Correct, inside the grouphead their is a gasket which is the same diameter as the filterholter which make the perfect fit so the presure of the water will not leak out. So now either the gasket is damage in one point so you have the leak from that point. Second the gasket have become hard so it can not make perfect fit with filter holder. In both above case you have to replace the gasket. Finally their is aposibility that the gasket is dirty with coffee remains and again we can not have a perfect fit. You can use a hard brash with the water running so you can clean the gasket.
With this case you can unsrew also the shower from the grouphead and clean it also for better coffe results

It does not fill with water


Check the nut on the top of the grouphead, make sure water is off and machine has cooled down, carefully remove nut, try not to damage gasket on the bottom of nut, check the screen and jet.

The left grouphead sounds like a different problem than the right group head. For the left grouphead, I would start by replacing the group electro-valve. With hard water, this can cause the valve to remain in the closed position even though the water pump is running.

For the right group head, I would want to see this happen. Usually, if the gaskets haven't been replaced in a while (if you are busy, your 'while' may be quicker than others), I would evaluate the condition of the rubber gasket. I would also look at whether you are tamping too much espresso grounds into the portafilter. This can cause a similar symptom as a bad gasket.
