No pressure to push water through - Krups Small Appliances Espresso Machine

release pressure by squeezing trigger then grab the brass quick connect fitting at the knurled section (at end of hose) and push it toward the pump. when properly pushed back, the hose connector will pop out.

This may sound stupid, but as a tech have done this before, so here goes. Unplug machine first, loosen the 3 screws from the back of control panel, then pull panel forward. Then unplug each plug from computer board and reinstall. Do one at a time. Each plug has a tab it on it so use your finger to push tab back. Plug machine in and see what happens. Check the one mounting screw make it is tight, have found them loose making the board vibrate.

Varem pressure tanks are simple pressure vessels. They have a chamber where the fluid comes in and a bladder that is pressurized on the other end that the fluid pushes against and compresses the air or other gas that is inside the bladder. When the pressure on the fluid line reaches the pressure switch setting, the pump shuts off and the gas pushes the water back out of the tank (if it is being used) until the pressure switch lower limit is reached and the pump kicks back on, pushing fluid back into the tank. This cycle continues until the fluid is no longer being allowed out of the system.

The bladder pressure is set when the system is empty of water and is set to a couple of pounds less than the low pressure cut on setting, that keeps the bladder from pushing all the fluid out of the tank before the pump comes back on resulting in a zero pressure moment which with some pump switches means it shuts down and has to be manually restarted.

If its on radiator, check the cap to see if it is bad seal, or you might have an cracked somewhere

Either the pipe for the water supply may be bent stopping the flow on your water pressure is too low. below is taken from manual.. The water pressure should be 2.0~12.5 kgf/cm2 or more to run the automatic icemaker. Checkup your tap water pressure ; if a cup of 180cc is full within 10 seconds, the pressure is OK.

Sounds like the pressure tank isn't working right. The pressure tank should have air in it that is compressed by the water, so that when you open the tap, the air pressure should immediately begin pushing the water. Water is virtually incompressible, so you need that air to give you some volume to be compressed. After the air pushes the water for a moment, the pressure drops enough so that the pump kicks in to maintain and restore that pressure. If you don't have such a tank, that's the problem. If you do have such a tank, then it may be full of water and you will have to find a way to fill it with air. Or, perhaps the tank is not piped correctly. I hope you found this helpful. Good luck.

If you are talking about a kitchen faucet. I would guess that you either have WAY too much water pressure or you are missing the little c-ring clip on your spout. Most are round plastic ring with split on one side. Some are metal. They usualy fit in one of the slots on the end of your spout. Hope this helps.

With the water faucet turned fully on and the power switch on squeeze and hold the trigger for at least 10 seconds to let the water flow push the air out and then it should start up. Also, adjust the nozzle by turning it to increase pressure.

Probably a waterlogged expansion tank. The tank provides a springy air cushion for the water to push against as it expands, and the air pushes back as the water contracts. This scheme minimizes the pressure change that would otherwise be caused by expansion and contraction of the water, giving the water somplace to go when it expands. If the air cushion is gone ... big pressure swings.
