    Try unplugging the plug for a few minutes. Did you?
    Any error it displays?

    The dishwasher has been washing worse for some time, as if the water was flowing under less pressure, it finally fell. I figured it was a pump. After dismantling, this proved to be true. I bought a new one and installed it. Now, when you turn it on, the pump pumping out the water starts and that's the end (something inside is ticking twice and the alarm goes off) ... The solenoid valve should open and take water, but it doesn't. Maybe I broke something on the way? It does not display any error.

    Well, the hydrostat valve needs cleaning. You know how to go about it, first open the right plate of the dishwasher and clean the entire water supply valve.

    The tube supplying water to the hydrostat was free, and the hydrostat I checked seems to be ok. I dried it and installed it.
    The dishwasher still doesn't work.
    I have a question about the code 3 and 6 (when I tried to click something on the buttons yesterday, these codes appeared, no code appeared automatically)

    Provide the exact E-no. And preferably a good photo of the dishwasher's rating plate because these photos are blurry.
    The pump should start as soon as the water spout pump has operated briefly.
    Before you fall into the frenzy of replacing it with another pump, check if all connections are properly made, even 1 mm is a problem. Maybe you didn't connect the water hose plug to Aquastop?

    I do not know if this is the answer to me, but according to this post: https://www.elektroda.pl/rtvforum/topic3468766.html (I was looking under the slogan, squeaks, beeps, intermittent sound signal) I will pay attention to the solenoid valve from AquaStop as you wrote.

    Then I will keep looking, or I will just call a service.

    For me, the dishwasher does not start washing and only emits short beeps (beeps, beeps) without a specific error code.

    And after the reset of 3 seconds of holding the start button?
    Then, by closing the door, the water outlet pump should start for about 1 minute and, if necessary, the signal to end the work. Yes check it out.
    If nothing happens And it worked before, then either the wrong connection or a little water spilled on the control or module.
    However, I would focus on water supply.
    I understand the pump did you buy from a reliable supplier ?!

    Hi.
    Thanks to everyone for your help.
    The Aqua Stop solenoid valve + water hose indicated by you turned out to be a problem.

    Something like that:
    https://www.klinikaagd.pl/czesci-agd/W%C4%85%...rki+1930mm+Scholtes+LV8343AN-%7C0;KL7217SU2/? gclid = Cj0KCQiAt_PuBRDcARIsAMNlBdqbUObJ_a3TktHWJiI7dBwBzTxIi8v9nIgEQXRE0gDsaHB8el1dMwIaAnOFEALw_wcB

    The cost is ~ PLN 80 and about 3 hours of work, including cleaning ?.
    Basic tools needed, such as a Phillips screwdriver, pliers and patience.
    Remember to provide yourself with hose clamps because the original ones are disposable.

    Thanks again.
    Dishwasher brought back to life and saved tens / hundreds of zlotys on service.

FAQ

TL;DR: Hold Start 3 seconds to reset; after door close the drain runs ~1 minute; “Focus on water supply.” If it still beeps and won’t fill, inspect the AquaStop hose/valve and connections, then replace if needed. [Elektroda, stiff12, post #18293325]

Why it matters: For Hotpoint Ariston LFT 3204 owners facing beeping/no-fill after pump work, this FAQ speeds diagnosis and avoids wasted parts.

Quick Facts

How do I reset a Hotpoint Ariston LFT 3204 after repairing the pump?

Hold Start for 3 seconds to reset. Close the door. The drain pump should run about 1 minute. You may hear an end-of-work tone. If it then stalls, check fill components. The expert advice: “Focus on water supply.” Inspect AquaStop, inlet, and connections next. [Elektroda, stiff12, post #18293325]

Why does my LFT 3204 beep repeatedly but show no error?

This symptom indicates the machine doesn’t fill. Reseat the AquaStop electrical plug. Verify the inlet hose connection. Even a 1 mm misalignment can stop it. Confirm the water tap is open. Then reset and try again. [Elektroda, stiff12, post #18289621]

How do I check or replace the AquaStop inlet hose/solenoid?

Use basic tools and new hose clamps.
  1. Unplug power and close the water tap.
  2. Remove the inlet hose with AquaStop from the tap and dishwasher; fit the new assembly.
  3. Secure with new clamps, reconnect, and test a wash. Expect ~3 hours and ~PLN 80. [Elektroda, pomykalamichal, post #18302158]

Do I need to clear stored errors after a repair on this model?

No. The machine does not keep old faults once fixed. You don’t need to reset a historical error. Diagnose current symptoms instead. [Elektroda, Anonymous, post #17029749]

What do code 3 or code 6 mean on the LFT 3204?

Get the exact E-number from the rating plate because code maps vary by model. Provide that E-number when seeking code definitions or parts. Without it, code meanings are unreliable. [Elektroda, stiff12, post #18289621]

The dishwasher drains, ticks twice, then won’t take water—what next?

This sequence points to the intake path. Clean the hydrostat and the water valve pathway. Open the right-side panel for access. Ensure the pressure tube is clear. Reassemble and test. [Elektroda, stiff12, post #17022731]

How can I confirm my new circulation pump is the correct part?

Verify the pump index against your dishwasher’s rating plate. Photograph both the rating plate and the pump label. Compare indexes before suspecting electronics. Incorrect indexes cause mismatches and odd behavior. [Elektroda, Anonymous, post #17029749]

After reset nothing happens—no drain and no fill. What could cause this?

Check for loose or miswired connectors after reassembly. Dry any moisture on the control or module. Even small spills can prevent startup. Reseat harnesses, reset again, and test. [Elektroda, stiff12, post #18293325]

Should I unplug the dishwasher to clear beeps or faults?

Yes. Unplug it for a few minutes to power cycle the controls. Plug back in and check for any error display. If issues persist, do the 3‑second Start reset and retry. [Elektroda, stiff12, post #17020528]

Which panel do I open to service the water-intake parts?

Open the right-hand side panel to reach intake components. Clean the hydrostat, its tube, and the water valve region. Debris here can fully block filling. [Elektroda, stiff12, post #17022731]

What should happen immediately after closing the door on a reset cycle?

The drain pump should run for about 1 minute. The machine may then signal end-of-work. It should begin filling if conditions are correct. [Elektroda, stiff12, post #18293325]

The hydrostat tube looks clear—what else should I check?

Return to the inlet side. Verify the AquaStop valve’s electrical plug is fully latched. Reseat the inlet hose at the cabinet. Misalignment, even 1 mm, can prevent fill. [Elektroda, stiff12, post #18289621]
