Tefal GV9460 - Strange noises when pumping water / gives little steam (video)

Good morning,

I have a Tefal GV9460 steam station. It is several years old, but so far it has worked without any complaints.

At the moment, its operation is far from ideal: when pumping water, it makes these types of sounds:

Very often - terribly irregular - he gives little steam. Sometimes it can work normally, and in most cases it works poorly - the steam then only slightly leaves the bottom of the soleplate. When shooting a pair, it is also the same - it can work once normally, and then a few times barely.

I would be obliged for some tip.

Thank you and best regards
Luke

And what about descaling?

First of all, thank you for your interest.

Maybe 3 weeks it signaled descaling - I unscrewed and took out the metal element, cleaned it and put it back in, then reset the control. It was good because my wife had fallen off the curtains all over the apartment.

Unless the metal element needs to be properly descaled, e.g. by boiling in citric acid?

Well .. twist the metal part out .. pour the water out of the boiler, knocking the entire station.
Buy a descaler even from a supermarket and pour it into a boiler.
Cap and set aside for two three hours .. wring out .. pour out .. rinse twice with water ..

Can I make this number with vinegar or citric acid? Boil vinegar or acid with water and pour it into the iron for 1-2 hours. Then discard and rinse with water.
If there must be a descaler, what? Ordinary marketer to clean this type of device?

Added after 3 [hours] 13 [minutes]:

EDIT:

you descale it in the boiler - first Kamyk, then Dr Beckmann. We will see what the effects will be. I understand that you cannot / do not make sense to turn on the station with the solution inside, heat it up and pass steam through the iron?

Of course you can't .. He will start to spit stone and dirt from his foot and then rinse it out at home.

I am very curious why everyone suggests vinegar for descaling - Has anyone managed to remove a gram of scale? Citric acid is better but the effect is poor ..

It is worth investing PLN 2 in a market descaler. Pebble is enough without unnecessary combinations in various preparations.

I always use acid in kettles - it cleans perfectly. I don't know a better way. I used dedicated espresso machines - now I have a stock so I don't use it. I clean all bathroom elements with acidic water or boil disassembled items in acid - perfect.

I did so too. Effect - the steamer stopped working, namely:

1. after turning on the station, literally after a dozen or so seconds, the LED indicating that the steam is ready stopped blinking (it started to glow constantly). Turning the knob towards more steam power, only a click of a relay could be heard and nothing else. After 2-3 attempts to turn it, the relay stopped working (I cannot hear it).

2. the boiler probably stopped heating because: after unscrewing the "descaling cap" there is no pressure and cold water comes out.

3.After the soleplate heats up and I try to press the steam button, a relay can be heard and nothing more UNLESS I hold the button, something starts to happen, and after it is released, the steam tries to fly out of the soleplate for some time. The situation is similar with the second button for the strong steam boost.

You can see everything in the video below:

The strange thing is that there was a problem with the steam shot, and now it has become an even bigger problem, and I kind of just descaled.

Thank you for your help

Good evening,

any ideas?

best regards
Luke

The descaler itself could not electrically damage the device.
Maybe it is such a nasty twist of fate - Please check the boiler heater, thermostat, thermal fuse and check the connection of the NTC sensor connectors on the side of the boiler.

It sounds scary - I have been playing with electronics all my life, but I haven't touched the steam stations yet. Are there any specific ways to do it, because it's a bit hard for me to get down to it?

In general, I dismantled the station, checked all connections, measured the heater with an ohmmeter (a few Ohm), I took my foot apart to clean it (something has been flying in it for a long time and it turned out to be this (about 2 cm long):



The effect is that now you can't hear the relay, the iron heats up for a long time, the steam station heats up for a long time, and the effect after pressing the button is that instead of steam, water flows from the foot.

Maybe I will ask - does anyone have a service for this model of a steam station? Then maybe it will be easier for me to get on with it.

I will be obliged.

Thank you
Luke

One can only ask how miraculously it is supposed to work without this piece check where it fits ...

Toni

do you think it's so easy to see where a little bit like that fits ???
Maybe a hint?

PS I check according to the comic service and I have the impression that the coil or the solenoid valve does not work. Unless it's because of that little element The only question is whether it has not broken and this element is not a piece of something bigger.

So give your pics, but try hard , and maybe we'll see what you don't ...

Please

Please check the solenoid valve by connecting it directly to 220V.
Of course, on opposite connectors. The third connector positioned across should not have a "transition" anywhere, even on high resistance - If it has, the coil is to be replaced.

Connect the solenoid directly to 220V and it should open, which you will hear for sure. You can quickly turn on and off the voltage so that the solenoid valve pops.

Please ignore the "fell out" element, it is a piece of a spring from the iron housing base.

I will check the solenoid according to the recommendation. Thank you.

If it is a non-influential element, why is Mr. Moderator misleading ???

this piece is a spring that "bounces" the hinge of the iron base where the cable enters from the station.

It breaks off right after purchase and 99% of users are unaware of it.
The installation of a working spring will in no way affect the use of the equipment, it cannot be felt in any way.

Hello, I have a similar problem with my (the same) steam station. Pressing the continuous shot of steam button has no effect. The burst of steam button works properly. Thank you for your help. Is the problem with the topic resolved? Maybe it will help me.
