Question about Nuova Simonelli Oscar Coffee Maker, Espresso Machine

1 Answer


Hi, THe boiler element has been replaced by service as well as the p'stat with a commercial one. Machine is 1.5yrs old. Everything works fine except grouphead temperatures are extremely low.(165Fmax) after 2.5hrs of being on. I double checked with a new digital thermometer and a manual one. the temps were identical. The steam is incredible and the pump works great. Please advise. cheers

My nuova Simonelli oscar doesn't heat

This is a good little machine. its basically a commercial machine shrunk down for home and is worth repairing even if you have to take it in. go to nuova simonelli usa website and download the parts manual and check the 009500014 thermal fuse and the 09500004 highlimit thermostat and see if one is gone or tripped. check the pressure stat, check if power to elements and if there is check to make sure the elements havnt failed from being heated with no water. like i said this machine is on par with a rancilio silvia so well worth repairing.

Water will not come out of the brewing head but will flow from the over flow valve.

I can think of 3 issues, the screen is clogged or the solenoid has a blockage at the pathway leading to the grouphead.

Nuova simonelli vip over pressure problem

Could be lack of water in the boiler, could be a faulty pressure stat or vent valve. Check the level probe first, then the vent valve and then the pressure stat. You can also use the manual fill to make sure water is getting to the boiler.

I have the same machine. I just went on the coffee geeks website and it is easily solved. Just add a few grains of salt to the reservoir - the sensor cant detect water that is purified - strange but true as four grains and it fired up just like that.

Nuova simonelli mac cup red light

It sounds like the thermostat on the boiler nest to the element tripped. Fill machine with water until you can see the level about half way, then open the right side of the espresso machine, you might be able to get to thermostat from the top of machine (make sure it is unplugged) then press the red pin on the boiler between the 2 wires, that should reset the thermostat, if it does not then it will need to be replaced. As for the water on the top of the group head, is there any way you can post a pic of the top, because simonelli made a few different head and I want to give you the correct advise.
