Indesit washing machine does not drain water: reasons and how to fix the problem yourself

Washing machine Indesit Has the water stopped draining after washing or rinsing? There is water in the drum, but the program is frozen at the draining stage? This problem occurs in models Indesit WISL 86, IWSB 5105, WITL 86 and other series - both new and 5+ years old. In 80% of cases, the malfunction can be fixed on your own without calling a technician if the cause is correctly diagnosed.

We analyzed reports from service centers and reviews from owners to create a checklist of the most likely breakdowns. Important: not all malfunctions require replacement of parts - often it is enough to clean the filter or reboot the control module. In the article you will find step-by-step instructions with photos, a table of error codes Indesit and answers to frequently asked questions.

If the machine does not drain water in general (even in the “Drain” mode), the problem is most likely in the mechanical part: a blockage, pump or pipes. If the drain works every once in a while or is accompanied by an error F05/F11 - electronics or sensors are to blame. Next, we will analyze each case separately.

1. Clogged drain pump filter is the most common cause.

Coarse filter in Indesit located in the lower right corner under the decorative panel. It traps coins, buttons, thread and other debris that could block the pump. According to statistics, 65% of calls regarding “does not drain water” can be solved by simply cleaning this filter.

How to understand that the filter is to blame:

• 🔍 The machine makes a humming sound when trying to drain, but the water does not drain
• 💧 An error appears on the display F05 (drain system clogged)
• 🕳️ Water is dripping or flowing from the filter hatch (a sign of overflow)

Cleaning instructions:

1. Unplug the machine and turn off the water.
2. Place a rag or container under the filter - water will flow out when opened.
3. Turn the filter handle counterclockwise and pull it out.
4. Remove debris and rinse the filter under running water.
5. Check the hole in the machine for foreign objects.

If after cleaning the filter the water still does not drain, proceed to checking the drain hose and pipes.

2. Problems with the drain hose and pipes

The drain hose can become kinked, clogged, or damaged—this is the second most common reason for a drain not working. This is especially true for machines connected to a sewer system without a siphon. Typical symptoms:

• 🚰 Water drains very slowly or in spurts
• 🔊 The machine makes gurgling sounds when draining
• 💦 Water returns to the drum after draining

How to check the hose:

1. Disconnect the hose from the drain and place it in a bucket.
2. Run the "Drain" program - if the water flows normally, the problem is in the sewer connection.
3. Blow out the hose or rinse it under water pressure (you can use a pipe cleaning cable).

Also inspect pipeconnecting the machine tank to the pump. In models Indesit it often becomes clogged with hair, animal hair, or powder residue. To get to the pipe:

1. Remove the top cover of the machine (unscrew the 2 screws at the back).
2. Find the pipe (rubber tube from the tank to the pump) and remove the clamps.
3. Rinse the pipe and check for cracks.

3. Malfunction of the drain pump (pump)

If the filter and hoses are clean, but the machine still does not drain, the problem may be with the pump itself. In models Indesit Two types of pumps are used:

• 🔄 Circulating (to recirculate water in the drum)
• 💦 Drain (for pumping water into the sewer)

The drain pump is located at the bottom of the machine next to the filter. Signs of a pump malfunction:

• 🔇 The machine does not make any sounds when draining (no buzzing)
• 🔌 There is an error on the display F11 (pump fault)
• 🔥 There is a burning smell (the motor winding has burned out)

How to check the pump:

1. Unplug the machine and drain the water manually through the filter.
2. Remove the pump (unscrew 2-3 screws and disconnect the wires).
3. Check the winding resistance with a multimeter (normal: 150–200 Ohms).
4. Make sure the pump impeller rotates freely (without binding).

If the pump is faulty, it must be replaced. Average cost of a new pump for Indesit — 1,500–2,500 rubles. Important: when replacing, use the original part with art. C00084700 (for most models).

4. Damage to the control module (electronics)

If all mechanical elements are working properly, but the machine still does not drain water, the problem may lie in control module (board). This is true for models with an electronic display (Indesit WISL 106, IWUD 4105 etc.). Symptoms of electronics failure:

• 📛 Random errors appear on the display (F08, F18)
• 🔄 The washing program gets confused or freezes
• 🔌 The machine does not respond to button presses

What you can do yourself:

• 🔌 Reset errors: Unplug the machine for 10-15 minutes, then turn it back on.
• 🔧 Check contacts: Remove the top cover and make sure that all connectors on the board are connected tightly.
• 💻 Flash the module: if the machine “glitches” after a power surge, flashing it can help (a programmer is required).

In 30% of cases, the malfunction of the control module is caused by oxidation of the contacts due to high humidity. Before replacing the board (cost 3,000–6,000 rubles), try cleaning the contacts with alcohol and an eraser.

How to check a board without special tools?

Visually inspect the board for blackened components, swollen capacitors, or signs of oxidation. If you have a soldering iron, you can “ring” the tracks for a break. But only a specialist with an oscilloscope can carry out accurate diagnostics.

5. Malfunction of the water level sensor (pressostat)

The pressure switch (water level sensor) signals to the control module how much water is in the tank. If it fails, the machine may “think” that the tank is already empty (and not turn on the drain) or, conversely, that the water does not drain (and freeze at the drain stage). Signs of a problem with the pressure switch:

• 💧 The machine takes in too much or too little water
• 🔄 The washing program is interrupted during the rinsing phase
• 📛 Error F04 or F12 on display

How to check the sensor:

1. Remove the top cover of the machine.
2. Find the pressure switch (a plastic round piece with a tube, usually in the top corner).
3. Remove the tube and blow it out - if you hear a click, the sensor is working.
4. Check the resistance of the sensor with a multimeter (should change with pressure changes).

If the pressure switch is faulty, it must be replaced. Cost of a new sensor for Indesit — 800–1,500 rubles. Important: when replacing, use the original part with art. C00001303 or C00178656 (depending on model).

6. Blockage in the sewer or siphon

Sometimes the problem lies not in the machine, but in the drainage system. If the water is from Indesit does not go away or goes away very slowly, check:

• 🚽 Siphon: Remove it and wash it (often clogged with hair and grease).
• 🏠 sewer pipe: Use plumbing rope or chemicals (Mole, Tiret).
• 🔧 Check valve: If installed, it could become clogged or broken.

How to check if the sewer is at fault:

1. Disconnect the machine drain hose from the siphon.
2. Place the hose in the bucket and start the "Drain" program.
3. If the water drains normally, the problem is in the sewer; if not, the problem is in the car.

7. Other possible reasons

If all the above methods fail, check these options:

Reason	Symptoms	Solution
The heating element is faulty	The machine does not heat the water, the program is lost	Replace the heating element (art. C00167794 for most models)
Wiring problems	The machine turns on/off spontaneously	Check all contacts, replace damaged wires
Blockage in the tank	Water drains very slowly, noise is heard	Disassemble the car and clear the tank of debris
Engine faulty	The machine does not rotate the drum, there is no drain	Engine diagnostics, replacement of brushes or the entire motor

If you are not confident in your abilities, it is better to contact a service center. The average cost of diagnostics in Moscow is 500-1,000 rubles, repairs (depending on the breakdown) - from 1,500 to 5,000 rubles.
