The situation when the washing machine Indesit stops draining water and often takes you by surprise. The drum is full of soapy water, the program has stopped, and the indicators are flashing in a panicky rhythm. This is a common malfunction, which in most cases does not require calling an expensive technician if you approach the matter methodically and carefully.
Before disassembling the unit or looking for a service center, you need to understand the physics of the process. Drain pump must pump out the waste liquid through a hose into the sewer. If this does not happen, it means that the water path is blocked, the mechanism is broken, or the electronics do not give the command to start. In this article we will analyze all possible failure scenarios from a banal blockage to motor combustion.
Modern models Indesit are equipped with a self-diagnosis system, which often suggests the essence of the problem through blinking indicators or displaying a code on the display. These signals cannot be ignored, as attempting to run a second wash with water in the tank can lead to serious consequences for the bearings and electronics.
Primary diagnostics and error codes
The first step should always be a visual assessment of the situation. Look at the control panel: are all the lights flashing at the same time or is there a specific code on? Models without a display are characterized by a series of flashes that need to be deciphered. For example, a flashing Extra Rinse light often indicates drainage problems.
If the code lights up on the screen F05 (or F5 depending on the series), this is a direct indication that the water level sensor (pressure switch) “sees” water where it should not be, or the pump cannot pump it out. Error F10 indicates problems with the control of the drain valve or pump.
⚠️ Attention: Never try to open the hatch by force if there is water inside. This will lead to a flood in the bathroom. First forcefully start the "Drain" or "Spin" mode.
It is important to distinguish between a software failure and a mechanical failure. Sometimes electronics simply freeze due to a power surge. In this case, completely de-energizing the device helps. Unplug the plug, wait 15-20 minutes, and plug it back in. If the problem was static or controller failure, the machine may complete the cycle successfully.
Cleaning the drain filter: the first step to the solution
The most common reason why Indesit washing machine does not drain the water, it is hidden in a banal blockage. Coins, buttons, lint and threads accumulate in the filter located on the lower right side of the case. A clogged filter blocks the pump impeller, preventing it from rotating.
To carry out the procedure, you will need a low basin or tray, since several liters of dirty water will spill out when the valve is opened. Also have a cloth and pliers ready in case you need to remove a deeply stuck object.
- 🔌 Disconnect the device from the power supply and turn off the water supply with the tap at the entrance.
- 🧼 Open the decorative panel at the bottom right (on some models you need to pry it off with a screwdriver or just pull it).
- 💧 Place the container, slowly unscrew the filter cap counterclockwise and drain the water through the emergency hose, if equipped.
After draining the water, unscrew the filter completely. Carefully inspect the space behind it. You can often find socks, bra underwires, or hairballs there. Clean the filter under running water, removing all deposits. Check whether the pump impeller, which you will see deep in the hole, rotates freely. It should spin easily, without jamming.
☑️ Filter check
Diagnostics of the drain hose and sewer system
If the filter is clean and the water is still standing, the problem may be in the line through which the liquid leaves the machine. The drain hose is a flexible tube that can become kinked, squashed, or clogged with soap and grease deposits on the inside.
Inspect the entire length of the hose. Make sure that it is not pinched by the machine body or furniture leg. If the machine is standing close to the wall, the hose may be kinked at the very exit from the housing. Straighten it, ensuring free flow of liquid.
Pay special attention to the connection point to the sewer pipe. Often the sink siphon or tee in the wall becomes clogged, creating back pressure. The water cannot escape and remains in the tank. Disconnect the hose from the sewer and lower its end into a bucket, then start the drain mode. If the water flows freely, the problem is a clogged home drain.
Plugs of petrified powder can also form inside the hose itself. Feel the hose with your hands: if you feel hard seals, it is better to replace it with a new one. The cost of this part is low, and the risk of re-clogging is high.
Checking the drain pump (pump)
When mechanical obstacles are excluded, it is time to check the very heart of the drainage system - the pump. Drain pump in cars Indesit is an electric motor with an impeller. Over time, it can fail electrically or mechanically.
To get to the pump, you often need to remove the front or bottom panel of the case, and in some models, even lay the car on its side (be sure to lay down a soft blanket). Find the pump: it is a plastic cylinder with wires and hoses that go to it.
| Symptom | Probable Cause | Action |
|---|---|---|
| The pump hums, but does not pump | Blockage or jamming of the shaft | Disassemble and clean |
| The pump is silent | Winding break or no voltage | Ring with a multimeter |
| Strong vibration | Shaft bearing broken | Replace the entire assembly |
| Leaking from the pump housing | Cracked or worn oil seal | Replacing the pump |
To check the electrical part you will need a multimeter. Disconnect the chip with wires from the pump and measure the winding resistance. The normal value for a healthy engine is 150 to 200 ohms. If the device shows one (infinity) or zero, the winding is burned out or shorted, and the part requires replacement.
Can I fix the pump myself?
Repairing the pump is only possible if a small object (bone, coin) gets into it and jams the impeller. If the winding is burned out or the plastic of the case is destroyed, repair is not economically feasible - it is easier to buy a new original Askoll or Plaset pump, which are often used in Indesit.
Electronics and wiring problems
Sometimes the pump itself and the hoses are working properly, but the command to drain simply does not reach the performer. Responsible for this control module and connecting wires. Vibration during spinning weakens the contacts in the connectors over time, and moisture promotes oxidation of the terminals.
Carefully inspect the wires leading to the pump. Are there any signs of melting, bites by rodents (if the car was in a garage) or corrosion? Oxidized contacts must be cleaned and treated with electrical contact spray.
A more complex case is a malfunction of the processor itself or the triac that controls the pump on the control board. If the module “does not see” the pump or does not supply voltage to it, professional resoldering of the elements or replacement of the entire board will be required. It is not recommended to climb into the board yourself without the skills of soldering BGA components.
⚠️ Attention: Before any manipulations with the wires and board, make sure that the capacitors are discharged. Residual voltage can be dangerous.
Rare causes and malfunctions of the pressure switch
There is one more element without which the drain will not start, even if the pump is working. This pressure switch (water level sensor). If it is “stuck” and sends a signal to the module that the tank is empty, the command to turn on the drain pump simply will not be generated.
Check the thin transparent tube going from the tank to the pressure switch. If it is clogged with powder or there is water in it, the sensor will not work correctly. Blow or flush the tube. Also check the sensor itself: you should hear clear clicks when blowing into it.
Another rare but possible reason is a malfunction of the heating element. In some algorithms Indesit the machine will not proceed to the draining and spinning stage if it does not heat the water to a certain temperature or, conversely, if the temperature sensor indicates overheating.
When replacing the drain pump, always change the rubber seal on the pipe. Old rubber becomes tanned and may leak a week after assembly.
FAQ: Frequently asked questions
Why does the machine drain water during washing and not after?
This phenomenon is called "gravity flow". Most likely, the drain hose is connected to the sewer incorrectly: its bend (loop) is below the water level in the tank (less than 60 cm from the floor). The water drains by gravity, the machine constantly refills with new water, and the wash cycle drags on endlessly.
Is it possible to drain water manually if the pump burns out?
Yes, this must be done before transport or repair. Place the drain hose on the floor into the prepared container. The water level must be below the filter level. You can also use a syringe or bulb to pump out the residue through the filter opening.
How often should I clean the Indesit filter?
The recommended frequency is once every 3-4 months or after every 30th wash. If you have pets or often wash fluffy items, you should clean the filter more often, once every 1-2 months.
What does all the lights on the Indesit blink?
Simultaneous flashing of all lights usually indicates a critical electronics error or problem with the control module. In this case, simply cleaning the filter may not help; diagnostics of the board will be required.
In 80% of cases, the problem is solved by cleaning the filter or straightening the drain hose. Do not rush to buy a new part until you rule out mechanical blockages.
