Question about Astoria Divina SAE-2 Coffee Maker, Espresso Machine

1 Answer

How are the 2 lines from the pressure gauge supposed to be hooked up to the tank? We just bought this machine and cleaning it up when we noticed the 2 lines coming from the gauge but only one line (the left one) goes down and is connected to a line across the bottom. The line on the right side of the pressure gauge is not hooked to anything but is zip tied to a piece on top of the tank that the steaming wand line is hooked up to. Why would it not be hooked up? Also in the group head, how do you get the hex looking thread or bolt/screw out of the head?

One of the lines is for pump pressure and lines up with the side that reads 0-15, that would be the one leading to the bottom of the machine. The other side is for steam pressure which reads 0-3 that is connected to the boiler. As for the grouphead if the screen is in place you should be able to use a 5mm allen wrench if that is what the screw head is, which is someone changed it from a flat head that is what they put in.

SOURCE: I have boiler pressure and steam coming threw the

Either the solenoids are damaged or blocked, or the metering jet on the top of the group is blocked, or the blockage is at the flowmeters. Do you get a reading on the pump pressure gauge when the buttons are pressed?

SOURCE: how to fix the wand

First check the steam wand tip to make sure it is not blocked. If it is clear remove the wand and run it under a faucet to make sure it is not blocked, it water flows freely, then the problem is on the fitting that connects the valve to the boiler, remove fitting and check, if clear check the boiler fitting, use a screwdriver and clear the fitting on top of the boiler.

SOURCE: I replaced the pump and it's working, however, when I turned on the machine and the boiler came up, there's a stream of pressured steam coming out of releasing through the top of the machine. Any id

Hopefully, your pressure gauge is working, and if it is at 1.2 bar or so, then you have a failed anti-suction valve or boiler safety valve.
The ASV is the smaller fitting; it might be stuck, so you could try tapping the little button. The boiler safety valve is another matter - it will open at some point past 1.8 bar, which means the pressurestat is shot or its adjustment has been tampered with.

It's most likely the ASV - they do get stuck open as well as closed...

Changed oil pump still low oil pressure 2004 twin cam

First off, if you are going by the idiot light, it COULD be a bad sending unit.
Either replace with a new one and check again, or hook up an oil pressure gauge (At 2000 RPM you should have 30-38lbs) to get a more accurate reading:

IF is is still ACTUALLY low, pull the relief valve spring and make sure its clean and nothing it blocking it from seating correctly.

A cracked cam plate could also cause a loss of oil pressure.

Finally, make sure that the oil line fron the oil tank to the pump (feed line) isn't plugged.

HS 80 it seems that when the primer bulb is pumped it pressurizes the tank and will not strrt

First, it helps to understand what the primer/purge bulb is SUPPOSED to do. It's only purpose is to bring fresh fuel from the tank to the carburetor and push any air and old fuel in the carburetor back to the fuel tank. The fuel lines should always be pretty much full of fuel (the retun line will have fuel and air in it).The purge bulb does NOT have to be completely full to work properly.There are also very small check valves in the carburetor near the purge bulb that allow the fuel to flow in the proper direction and not backflow. Sometimes, they go bad or get stuck. This may have happened in your carb, or there is a blockage somewhere.Air and old fuel going back to the fuel tank the way it is supposed to does not pressurize the tank.Also, the tank is supposed to be vente (look for a small black piece called a duckbill under the tank cap). Make sure it is clear and clean. Check all fuel lines for blockage or debris. Sometimes, the lines themselves deteriorate from the inside-out and it is hard to notice until problems like this occur, If you want, remove and check ALL the gas lines. Remove the purge bulb and spray liberally underneath it with say WD-40. It sometimes cleans and clears the check valves.Try all these remedies and post back. I will see your comment and reply.

I just bought this unit took it home read the instructions loaded the gun with nails hooked up the cables opened the gauge turned on the unit and i waited for the tank to fill with air and the gauge...

There are usually two gages, one for the pressure in the tank, the other is for the regulated pressure in the hose going to whatever tool you have connected. I assume the tank filled up and the tank gage registers pressure in the tank. When you said you "opened the gage" I am guessing that you turned the knob counter-clockwise which would be the normal direction to open a valve. However, this is not a valve, it is a spring loaded regulator device. When you turn the knob counterclockwise you are removing all pressure from the spring which sets the regulator to allow zero pressure in the hose. Turn the knob clockwise to increase the pressure in the hose. I hope this was helpful. Good luck.

I bought a new tank for my reverse osmosis water treatment and it did not come with directions. It's supposed to be ''charged,'' whatever that means. When I hook it up to my system it does not fill with...

Typically a reverse osmosis storage tank should have a precharge of approximately 7 psi. Depending on the make/model of your tank it may have a higher charge currently which would cause the tank to not fill. There should be a schrader valve on the bottom or side of the tank. Using a tire gauge and bicycle pump you should be able to check the current pressure in the tank and adjust it up or down to 7 psi.

What is the range that the fuel lines should have when hooking up a fuel pressure gauge to the fuel lines on a 2001 chevy s-10 ZR 2

You want to make sure you are hooked up to the pressure line. This is the larger of the two lines. Depending on the engine pressure is in the vicenity of 29-36 psi or can be 9-13 psi. The fuel pump is in the tank and these trucks have wiring issues.
