Nuova Simonelli Popular Questions, Answers, Tips & Manuals

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.

It sounds like the issue may be related to the water flow, as you mentioned that the machine is not filling with enough water. This could be caused by a malfunctioning water solenoid, pump, or manual water fill valve. To troubleshoot the issue, you may want to try the following steps:

1. Check the water supply: Make sure that the water supply to the machine is turned on and that there are no kinks or blockages in the water line.
2. Check the water filter: Check the water filter to make sure it is not clogged or needs to be replaced.
3. Check the water solenoid: If the water solenoid is not functioning properly, it may not be allowing enough water to enter the machine. Check to make sure that the water solenoid is receiving power and that it is opening and closing properly.
4. Check the pump: The pump is responsible for pumping water through the machine, so if it is not working correctly, this could be causing the issue. Check to make sure that the pump is receiving power and that it is pumping water through the machine.
5. Check the manual water fill valve: If the manual water fill valve is not working, this could be preventing water from entering the machine. Check to make sure that the valve is open and that water is able to flow through it.

If none of these steps resolve the issue, it may be best to contact a professional technician to diagnose and repair the machine.

You can't run a coffee machine off a generator, it draws too many amps, and needs stable voltage.

Hello Philip When you unscrew the burr bolts usually you do it to replace them. The lower burr holder plate must be stopped from spinning with 1 screwdriver put in the exit hole of the coffee and touching the burr holder flaps (usually they are 3 flaps). The screwdriver will block and you can freely work.

They have Service Manuals, but your 'Mia' machine doesn't exist, perhaps it isn't on the US market. https://www.simonelliusa.com/products/all-equipment-documents-archive.asp Service Manual for a Musica model https://www.google.com/search?q=Nuova+Simonelli+Mia+wiring+diagram ..

The oven should be connected to a dedicated circuit without coffee makers.

After I press "turn on" button heat light just flashes for a second then pump starts. Without any delay immediately after pump starts I can see all water running through 3-way solenoid valve to the drip-tray. It runs without interruption approximately 90 seconds until safety timer turns the pump off and "empty tank" light is turning on. Shut it down, turn it on and everything happens again.

is it in the group or in the hot water dispenser? check if solenoid open.

Most domestic coffee machines only have a small heater tank. I would suggest that after 5 cups, the tank cannot retain enough heat as the cold water from the supply has refilled it and it has to reheat again. If it wasn't doing this before, you may have to contact a service Company.

Internal board failure, needs service.

Is it constantly filling even the machine not in use, or just when your brewing, the pump keeps on running? If it is constantly filling that means you filling solenoid valve are mechanically open already. if only when brewing, check you water level sensors.

yes, just behind the tap there is a mixing valve that you can adjust to mix steam and water. this steam is the one making your water hot. open the top cover behind the tap and follow the pipe. there you will see it and adjust.

if you remove the drain tray, there is another plastic cover with screws. remove that too. inside on the right side you will see a black box with a yellow round cap. peel the cap off then you can see a screw. there is also a label that describe the direction of rotation. adjust it there. this is to adjust the pressure of steam. as your machine is increasing steam pressure, it also increases the water temp.

is it leaking on the side of the portafilter or what you mean is the dose is short? if dose is short, you can calibrate by pressing the fifth button on that group about 5 sec. then it will blink. prepare you grind in the portafilter then put it in the group. brew with the appropriate button the manually stop at the right level or quantity in the cup. you can do this with all the doses you require. Now by pressing the fifth button again 5 sec. you can exit programming mode.

open the right side panel and you can see the heater of the tank, with that heater, there is a thermal cut out switch that you can reset by pushing the red button.

The flowmeter is clogged. if you can clean it, will save you money, if not, just replace it.

you mentioned you bypassed the pressure switch but still the same... you have a busted heater.

the pump is not getting water, make sure it does
