Question about DeLonghi BAR 140 Espresso Machine

1 Answer

Noisy pump when i first used the machine it was only noisy until the coffee started to flow and then it just hummed nice and quietly,now it is noisy for the full duration of the pour and if you have two cups you have to hold onto them as they would vibrate away from the pouring coffee.Any suggestions? I've only had the machine for 3 weeks.(great coffee though)

Re: noisy pump

Obviously, this unit has a warranty. Are you packing the coffee too tightly? Run the unit without any coffee and see if the vibration is still there. If it is, get it fixed. If not, modify what you're doing.

Any way to quiet this thing down. We need ear plugs to use it.

Guess you are somewhat exagerated!
Does it work ok? If makes your coffee, leave noisy it as it is.
Maybe you could contact the manufacturer of your unspecified cand noisy coffee maker trough thier website. and ask them if there is a way to "silence" it.

How do I prime my machine?

Hi again, When the machine is turned on, open the steam tap until approx 100mls of water comes out. The pump will sound really noisy, until the water starts to come through. Then the pump should not sound as loud. Dazza REPAIRER

I have a Starbucks Barista Espresso Sin 006 that I got used from someone. They hadn't used in it awhile and didn't have the manual. I'm told that before using I should Prime it. The instructions says...

Since the machine hadn't been used in a while you might have a stuck check valve in the pump. You say it hums. Does it rattle or just hum? If it hums something is stuck in the lines that is keeping the pump from moving water. If it rattles and makes a lot of noise its the pump check valve or it could be a plugged flow meter/ intake line.

Water flow is slow and noisy

The pump is a vibratory pump and it will make some noise.

Take the lid off the reservoir and watch at the hose coming from the relief valve (the short hose).
Pull a shot.
If water comes out of the hose, the relief valve is opening on high pressure. The pump gets extra noisy on high pressure too. This happens when the water flow is blocked due to coffee ground too fine, coffee tamped too hard, pluggage somewhere.
Pull another shot but this time with the basket removed from the portafilter.
If there is still water coming out of the short hose, you need to descale the machine. If there is not water com ing out of the hose and the pump is quieter, adjust your grind or your tamp.

I just got a new Rancilio Silvia, it's making a loud knocking noise. Is this common if not what should I do?

The pump is a vibratory pump on rubber mounts. It makes a loud buzz when running.

The pump makes a knocking sound when it is out of place on the mounts and banging into something and when the pressure is high (water flow is blocked)

Open the wand all the way (no back pressure) and make some hot water. If the noise changes to a quiet hum, get a warranty repair. If the noise changes some but is still a knock, take out the water reservoir and the pump shield.

You can see the shield by looking down into the cavity left by the reservoir. One screw hold the shield in place. Remove the screw and the shield, and wiggle the pump around in its mounts until it does not bump into anything when running. Then replace the shield, screw and reservoir.

I was just given a rancilio audrey and a matching rancilio grinder. However no water is coming through the group heaed, just steam. I can't make coffee! The pump hums quietly and sounds like it is running...

Remove the shower screen and screw from the head, make sure screen is clean and run head without screen in place, if you get a good flow, problem on screen, if not then problem is on the inside of the machine between top of the head and pump. You can try descaling the machine.

Pump is not working

The reason could be the following.
You used your machine on a mains working with 50 cycles/sec. In U.S. frequency is 60 cycles /sec. this could alter the working of the oscillating piston in the pump. The impedance of the coil is somehow about 20% higher on this mains, reducing so current and power of the pump.
To be quite shure of this, try to fill the pump thoroughly with water.
(Disconnect machine from mains, use Low pressure hose , max 0,5 bar, tied to the inlet -where the water tank feeds-, and fill until water comes out of the open hood)
If now the same humming persists an no pumping effect is noticed, i even will be a bit wiser knowing that 60Hz is not good to 50 Hz pumps.

Low water flow from gaggia evolution only 6 months old, have tried descaling, no obvious scale found in machine. pump starts but goes quiet, very feeble flow of water.

I have now solved this problem. The lack of flow associated with the pump working but running quietly is caused by the Group Head being blocked with limescale. Normal descaling cannot remove it because it cannot penetrate the Group Head.
Removing the Group Bell can be achieved using a collection of screws (see photo) and works no matter how stubborn the thing: levering it with a screwdriver in my case was impossible as it was so well glued on. 6d47425.jpg
I figure that the advice to replace the rubber seal once per year is a good one because it forces you to remove the Group Bell and clean it out.
