Nilfisk Vacuums\015 Bought a nilfisk C 125.3 today, & followed instructions & watched youtube vids to see how to operate, .tries it, but the pressure keeps dropping. The motor cuts out after about 1 minute and I get about 3 seconds of pressure before it drops to a dribble. what might I be I doing wrong? Do I need to 'prime' it somehow?.Hope someone can advise. .Robin\015

How to Identify and Fix Common Vacuum Problems ?

Our sources include academic articles, blog posts, and personal essays from experienced Vacuum Technicians :

The number one cause of low or no pressure when using a pressure washer is a blocked or worn nozzle. Blocked nozzles will prevent water from escaping, while a worn nozzle will allow too much water to pass through, causing the pressure to drop.
Pump sucking Valves dirty, worn out or stuck Pump seals worn out Check that hoses and connections are airtight. Clean and replace or refer to local Nilfisk distributor. Machine stops Fuse has blown Incorrect mains voltage Thermal sensor activated Nozzle partially blocked Replace fuse. Switch off other machines.
If the machine is pulsing when on standby, is the garden hose supplying the pressure washer fully uncoiled? If the machine is pulsing whilst in use, it may be that the accessory you are using has a blockage. Clear by soaking the accessory in warm soapy water and then rinsing out under the tap.
Nilfisk products have a standard 2-year warranty, certain products are eligible to a warranty extension of 1-3 years depending on the product. This only applies when you register your eligible product with our warranty extension program within 30 days of purchase.
If this is a gas powered pressure washer, then the pump is not going into by-pass mode and the pressure build up is overloading the engine causing it to shut down.
Practical hose length limit: 200-ft

This is assuming the hose and pressure unit are at the same elevation. And you`re on a relatively straight line of sight to the pressure unit. You could go well beyond 200-ft but it quickly becomes pointless due to risk of hose damage, weight of dragging the dead hose around…

A clogged or improperly sized filter reduces the amount of liquid to the pump inlet, which can cause cavitation and even severe pump damage. Reduced inlet flow results in reduced flow to the system, which works to reduce system pressure as there is less resistance to the lower flow being produced.
Replacement wet & dry PET cartridge filter. Compatible with 11564 and 67098 . Washable to extend usage. Enables wet, damp or dry use without removing filter.
Water flow may be restricted to the pressure washer, although the causes of pressure washer surging can be varied. First, check that all hoses are free of kinks, leaks, or blockage. Make certain all hoses and fittings are connected properly. Make sure to open the faucet/spigot to full force.
You may need to rebuild or replace the pump. If the pump is more than a few years old, and you use the pressure washer fairly often, replace the pump. If the pump is relatively new, and you don`t use the pressure washer often, either rebuild the pump or replace the pump seals.
A dirty inlet or discharge valve is the most common cause of a pulsating pressure washer. Dirt or hard water can get caught up in these little divots. It is important that you clean out these pieces every so often to prevent these kinds of problems.

My Pasquini Livia 90 S/E will not stop heating water. This builds up too much pressure. I have unplugged the machine and let it cool off and turned it back on and got the same result. I can relieve the pressure by opening the steam valve, but since the heating element does not turn off it builds up too much pressure very quickly
ANSWER : Your thermostat is failing. Given the initial price tag, look at your warranty options first. If you are out of warranty, then lets proceed.

Since there is not a parts / assembly diagram to be found, you will need to disassemble your espresso maker to the point where you are able to get access to the heating element. Don’t disassemble anything that has to do with the water / steam path though.

Once you find the heating element, follow the wiring. You will eventually come to a small metal can that will be pressed up against the heating element, but more likely attached to the steam reservoir / hot water tank.

Make note of the part number written on the thermostat, and search the internet for a replacement. If there isn’t a part number, and I suspect that there isn’t, then you likely will have to consult the manufacturer for replacement part.

I am trying to install a train air horn. i bought a viair compressor for it. the horns themselves have a 12 volt hookup going to what i believe is acting like a solenoid. when charged, you complete the circuit and walah, the horn blasts. the problem im having is when the compressor is building pressure, the air horn is automatically putting out a dull sound, getting louder as the pressure gets more and more. it sounds like its out of one horn however. it is doing that without the 12 v hookup. is
ANSWER : Hi! just a tip regarding the sound that comes up when building pressure. Is there a gasket or rubber seal on the horn? You may need to replace this for it may be worn. The air may be coming out of the worn seals resulting to sound even when not triggered. Hope this helps and have a good one!
