Indesit IWUD4105 Washing Machine: Blocked Pump & Hydrostat Replacement - Water Drawing Issue

Question

In the Indesit IWUD4105 washing machine, the handkerchief got into the pump and it blocked. I cleaned the pump and hoses with the hydrostatic hose. After starting the washing program, the pump works for a long time and does not draw water. Only when I take off the hose and lightly blow the hydrostat, water begins to take in. I put a new hydrostat on, and so is the symptom. If any of my colleagues knows what this is, please help.

I greet everyone.

Clean the hydrostat cup, then where does the hydrostatic hose come from.

OK, I'll do it tonight and write what the effect is.

olomaj · Answer

I don't see any mugs in this washing machine. The tubing goes directly into the drum. Thanks for the hint. Maybe some more suggestions? best regards

And did you blow the hose? Is it clear? Sometimes the hose can rub or break somewhere, and then there is no vacuum that activates the hydrostat.

olomaj · Answer

The tubing is purged free. I will check if it is not damaged as you suggest.

olomaj · Answer

The hose is checked, functional, no damage.
In addition, I disconnected the controller from everyone for one day
plugins. After everything is assembled, the washing machine behaves like this
itself, i.e. it pumps out water for a long time but does not consume it.
Maybe some hints?
best regards

Kenworth 18 · Answer

Take off and check if there will be something blocking the so-called siphon, i.e. the drain hose connecting the pump with the tank.
There has to be some reason the vacuum is not being built up which triggers the hydrostat.
If there was a handkerchief in the pump, something could also be stuck in the hose.

olomaj · Answer

OK, I'll do it again, because I've already cleaned the pump and hose connecting the pump with the drum.

And have you not mistaken the hydrostat hoses?
When you blow in the hose, then the washing machine should stop drawing water.
While taking water into the tank, the hose creates pressure (and not a vacuum, as some people write here) and after reaching the correct water level and the associated pressure in the hose, the hydrostat switches its contacts and the washing machine stops drawing water and the next washing cycle begins.

Kenworth 18 · Answer

I am sorry my fault and admit to the mistake.
A colleague is right, buddy drill, only that the usual washing machines have a cube that is connected to the hydrostatic and it is rather impossible to attach it otherwise because of the tabs. Of course, I could be wrong.
The author of the topic is an electrician and the probability of making a mistake when connecting the hydrostat is rather negligible. I think so.

wiertacz · Answer

Perhaps it is impossible to connect the cables incorrectly in today's washing machines.
In my 26 year old washing machine, each cord connects separately and such a mistake is possible.
But this does not change the fact that the symptoms indicate the opposite effect of the hydrostat.

Kenworth 18 · Answer

The author of the topic writes that he replaced the hydrostat, the only question is whether it is an original or a cheap replacement or universal. Maybe the hydrostat itself has a different contact system inside, which forces a different connection method.

niewolno2 · Answer

If the hose enters the tank directly, check the patency of this hole, for the sake of peace and quiet, I cut off a fragment of the old hose connection, if it is possible and put it on again, so I am sure that it always enters tightly.

Module for reprogramming - for this ailment in IWUD nothing else helps and there is no point in producing more posts on this topic.

olomaj · Answer

Thank you all for your interest in the topic.
So far I have not fulfilled your recommendations because I am not at home. As soon as I can, I will work on the washing machine.
The cables on the hydrostat have a plug that cannot be connected incorrectly. I changed the new hydrostat also from the washing machine to the probe
INDESIT-original. I will also check the accessibility of the inlet from the drum to
he will write about everything.

best regards

olomaj · Answer

I replaced the entire plate and the washing machine works. Thank you for your interest.

Added after 8 [minutes]:

There is another problem with the indesit iwc 6105 washing machine.
No lights are on.
I replaced the capacitors and thyristor on the board. Nothing helped, I also replaced the door switch.
The door switch comes with 194V, and I think it should be 230V
What else should i do
I am asking for hints.
