Slow water coming out of Group heads - Wega Mininova EPU Espresso Machine

It sounds like you may have a clog in the water line or the tubing that leads from the water tank to the 2nd group head of your coffee machine. To address this issue, you can try the following steps:

1. Disconnect the tubing from the group head and the water tank.
2. Flush the tubing with hot water to remove any buildup or debris.
3. Check the inlet and outlet holes on the group head to make sure they are not clogged or obstructed.
4. Reattach the tubing to the group head and the water tank, making sure it is securely connected.
5. Test the water flow to see if it is now flowing properly.

If the water still does not flow after following these steps, you may need to disassemble the group head and inspect it for any further blockages or damage. If you are not familiar with this type of maintenance, it is recommended to seek assistance from a professional.

Hi Ewah,

If you are getting steam from the group and no water when you turn on the water button - then you may have a group blockage.

The fix depends on the type of machine you have.
If it is a commercial type - then call in a qualified coffee technician.
If it is a domestic type like rancilio sylvia, the you could try to descale - maybe too late, but worth a go.JURA descaling tablets
If when descaling, no water is coming from the group try leaving the steam tap open when asking for water.That way you may get the descaler liquid moving inside the boiler and it may clear the solenoid valve blockage.
If no joy with that you may need to replace solenoid valve.

Domestic machines need regular descaling to avoid group blockages.

Did you try adjusting the group head screw? And/or cleaning and checking the valve in the group head? Good visuals and instructions here: https://myprojectsandmods.wordpress.com/2014/10/27/delonghi-ec702-espresso-machine-no-water-flow-fix/

There could be a couple of reasons for this. The simplest could just be that you need a new group (brew) solenoid valve, yours might not being opening fully. You could also have a clog some where. Take the shower head out and soak it in PuroCafe over night. If that doesn't fix it you would have to start checking the jets in the head and or the tubing that supplies water from the heat exchanger to the groups.

Check the metering jets and filter on the top of the group heads.

There might be one of 2 things going on,
1- the exhaust tube is blocked.
2- one of the three gaskets in the group is on backwards.

Remove the shower screen and clean. If shower is clean then line to head is clogged.

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.
