[Solved] Karcher Puzzi 10/1 Vacuum Cleaner: Pump Issue - No Water Spray, Quiet Sound, & Recent Replacement

Hello, I have a problem with the pump in the karcher puzzi 10/1 vacuum cleaner. I turn on the spray button, but the vacuum cleaner does not give water, you can only hear quietly that the pump is going. And she always walked louder. What can this be caused by? Can it be fixed somehow, is there service waiting for me? I will only add that 3 months ago the vacuum cleaner was under warranty and they replaced the pump. Only then could it not be heard at all.
Thank you in advance for your answers and ideas what to do, best regards

Maybe you need to return to warranty service? If you have a guarantee, don't even think twice. The second thing you need to check is that the pump is not pulling air from the duct somewhere (leak). Alternatively check the pump to see if it sucks in water. The pump may work but it will not suck in water, as it may even be leaking. What is the pump there? Pump type and data. If this type of pump then you can replace the orings. Then the pump leak will be removed, but it does not always help. Sometimes the piston curves and then it is replaced only with a new pump.

Unfortunately, the warranty is over. So I will have to undress and see what the pump is there because I don't even know. Is there a problem dismantling the vacuum cleaner to get to the pump?
The service for the exchange wishes 500 PLN ... They do not play in repair or regeneration.
So from observation, the problem is that it doesn't take in water, you don't hear any leaks.

You won't hear because it's not a 10 bar pump. If you want to do it, you have to undress, otherwise you will not check. Apparently there are two but I'm not sure. It will only be left for you to buy a new pump.

Are there any substitutes for this pump? I've heard that they also fit in with Zelmer vacuum cleaners. Can I have the exact name of this pump so that I can check the price? First, however, check if my one can still surprise.

You will get the exact name when you remove it from the vacuum cleaner and read it from the pump. I am not sure if exactly this model is used in your equipment.

I will let you know in a few days how to remove the pump because now I have no way. For now, thank you for your help, best regards

Check that the electromagnet in both directions is live. If so, in an electronics store, buy a medium-sized diode for about PLN 1 and mount it on the power cord. If the pump is quieter, it usually means that the diode on the cables has been damaged or embedded in the housing. Let it stay there because it leads in both directions. Of course, it won't hurt to undress and check for mechanical damage, e.g. spring or valve.

The diode is probably there, but it doesn't get damaged that way. If it's damaged, it's for a reason. And after mounting it will damage again. If it is damaged, it is the fault of the pump.

Did you repair the equipment?
I have exactly the same problem - the pump started to work much quieter and does not give liquid.
I request information.

I haven't fixed it yet, because I'm on vacation, when I come back I will deal with this topic.

A standard fault, the piston in the pump has stopped or the valve may be hanging, something may be clogged.
You have to undress and clean.
After dismantling the pump, we should see such elements.

You must not make a mistake in the folding process, the order is important

Good morning,
I disassembled the pump, cleaned the parts, turned it and it still does not work, all the time it strangely quietly walks and does not take water. What could still be the reason? Where to look for her? Maybe something with this diode is wrong? Where can I find this diode?

PS: Is there any instruction on how exactly this pump should look inside?

Sometimes the O-ring exchange helps, and sometimes the replacement and the piston. But not always. If you don't have a back room with spare parts for these push-ups, it's a waste of time and work.

So I will rather not do anything myself ... And tell me how it is with this regeneration? Companies announce that they are doing it for 35 zlotys, does it make sense?
Here is the link to such an auction:

These pumps die only when their winding burns, it is worth fixing it.
Regeneration consists in cleaning it and possibly replacing the seals, I do it personally.
As for the diode, the usual half-conductor diode to cut off a part of the sine wave, these pumps run on one half.
If the diode were burned, the pump would be silent, if it wasn't there, the pump would not pump because the piston would not perform the entire range of motion.

Depends on how you do it. One does it so that it replaces the O-ring and the piston, while the other replaces everything but the housing and the coil remains old. If someone does it right and comes. And PLN 35 for regeneration is less than for the entire pump. Talking to the guest. Often, rubber bands strike, they act as a valve.

If the diode is damaged, it is for a reason. Even after replacing the diode after another time, the diode will be damaged again. The reason for this is the pump coil.

Thank you so much for your help, I will call a company tomorrow that is regenerating the pumps.
best regards

The pump came after regeneration, everything works nicely, I close the topic.
Thank you for your help, best regards
