The problem manifests itself by very little water being served. I have taken everything apart a number of times to try fix the problem. I have replaced all the silicon hoses but still have the same problem. If I push down on the plunger stem while the machine is going through a cycle I can get it to work. If I do not push on the stem I get a little water but then I can hear bubbles in the tank indicating that the silicon seal at the bottom is not sealing.
My impression is that either there is not enough suction or there is a problem with the seal at the bottom. Looking at it I can see nothing visibily wrong with the seal.

Re: Lower tank lose of pressure
The only thought I have is that knowing the brewer is supposed to be left on for a long time and water kept in it a long time, Are you doing this? They talk about leaving it on all the time unless your not going to use it for days. It only has a 60 watt heater in it. So its going to take a long time to ready up to dispense. I am talking over 10 minutes. Do you get the ready to brew light before brewing?

There is a schraeder valve at the top of the tank. Check the air pressure with a tire gauge. It should be two psi lower that the cut in pressure. eg: If you have a 40/60 pressure switch, the tank should read 38 psi.If it is lower, charge it up with air. If it loses the air again, the tank needs to be replaced. The gauge at the tank is rarely accurate so I would an outside sillcock pressure gauge to determine your system pressure so you can set the tank pressure properly. Good luck!
Check the clean water holding tank. I had this problem and found that was a crack near the outlet on the bottom of the tank. I replaced the tank and resolved the problem. I have taken this machine apart several times, if the tank is not the problem with yours, check the water tube.
Shame you did not leave the model type of "Karcher" pressure washer as there are several models.
There is normally a special oil which should be changed, expect this to be done at least every three years or less.
1/. These pressure washers should only be serviced or taken apart at one of their registered dealers, as far as pulsating if you have the cheaper models then they do not last very long.
2/. Their better more power washers pulsate all the time & that is why they are sold new with a special fitted container, this allows all the pipes & water connections to fit & hold in supplied container, which allows you to give a higher or lower power controller where their yellow pipe that attaches to the gun fits on the machine.
3/. Where the pressure pipe goes into the power washer it has a black knurled fitting to adjust the pressure higher or lower out put, this is the only adjustment you can make on these power washers, everything else needs to be done by their approved dealers, situated all around the world, try finding your nearest dealer through the Internet.

I have the same issue. I have tried replacing the O-rings in the water heating element and the steamer, and it still does this. For a temporary fix, try running the steamer for about 30 seconds, or until it is running "full steam", and immediately make your coffee. This has worked for my machine for the last 4 months. It is used about 5-10 times a day at my work, and this still is working. I believe the issues is it is losing pressure somewhere, and the water cannot travel through the infuser. I have taken apart my machine more than 10 times, and I still cannot find out where the pressure loss is. I know this is a temporary fix, but it will work until something more permanent can be done. Hope this helps!
Seriously it may be time to buy a new one. But you have little to lose. Try prying the body apart with a sharp knife edge. If you can get it open, wash it in water to get the coffee out. Water warm to the touch is ok. Leave it in a warm dry place like a sunny windowsill for a week or so. Reassemble it, give it a good charge and see if it works. It may well, electronics are not as delicate as some people think.
3 psi is a little over the average, 2.5 is the optimum setting. If it empties itself, it means that the safety valve is working,which prevents any kind of damage to pipes etc...Make sure the valve is open and close at the right time and top up the system slowly rather than in a hurry. If the system requires regular top up then there must be a small leak somewhere, so it is best if you can fix that too. Remember that there are some solutions that are added to the water circulation and if you are constantly topping up with water then you are losing these solutions that prevents rust build up etc...Hope this helps.
Replace your overflow tank cap. This is a small problem that a lot of people overlook and end up replacing everything. What happens is the heated water and engine heat causes the seal to break down, and overtime the cap/seal can no longer hold pressure which causes the car to have a high temp or over heat. It will also cause you to lose coolant sometimes if you find yourself refilling on a regular basis. Try a new cap or have yours pressure checked at a local store. A new cap is $7-$12
When you remove the dirty water tank, on the machine, there is a screen that gets clogged and will prevent good suction, is this one clean? If it is, do you feel suction at that screen, if so then there is a problem with the tank. If no suction there, then you will have to check it over for a air leak or a bad seal.
