The situation when Ariston washing machine stops draining, takes you by surprise and often leads to panic. The laundry floats in dirty water, and the wash cycle freezes in the middle without proceeding to the spin cycle. This is one of the most common problems that owners of equipment from this brand face, and in most cases it can be solved without calling a technician.
Before you sound the alarm, you need to understand that the drainage system is not only the pump itself. This is a complex complex that includes filters, pipes, water level sensors and an electronic control board. If Ariston washing machine does not drain water, this may be the result of a simple blockage or a serious breakdown of the electronics.
In this article we will analyze in detail the algorithm of actions that will help you diagnose the problem yourself. You'll learn how to decipher error codes on your display, safely clear debris from your system, and understand when parts actually need to be replaced.
Decoding drain error codes on the display
Modern models Ariston equipped with a self-diagnosis system that displays alphanumeric codes when problems are detected. If a combination of symbols lights up on the display, this greatly simplifies the search for the cause. Most often, drainage problems are indicated by codes F05, F09 or F10, although the exact marking depends on the series of the machine.
Code F05 indicates that the pressure sensor (pressure switch) has detected water in the tank when it should not be there, or vice versa - the water does not leave, although the pump is running. This is often due to a clogged or stuck sensor itself. Code F09 indicates that the tank is overfilled with water, which may indicate a malfunction of the water supply valve or a problem with the electronics that does not give the command to drain.
What should I do if the error code flashes and disappears?
If the error code appears and disappears, it may indicate an intermittent fault. Check the wires going to the pump for oxidation or kinks. Sometimes it is enough to simply move the connector to restore contact, but it is better to clean the terminals.
It is important to understand that the machine’s electronics respond to physical parameters. If the pump is humming, but the water is standing still, the system will stop the program after a certain time (usually a few minutes) and display an error. If the pump is silent, the problem may be a lack of voltage on it or a burnt-out control module.
Error codes are the first and most accurate source of information. Do not ignore them, even if the machine starts working after a reboot.
Primary diagnostics: checking the hose and sewer
The most commonplace, but often overlooked reason is a mechanical obstacle in the path of water. If Ariston washing machine does not pump water to the drain, the first step is to exclude external factors. Do not rush to disassemble the case, start by inspecting the communications.
Check the entire length of the drain hose. It should not be twisted, crushed by furniture or have sharp bends. On top-loading models, the hose may be pinched between the machine body and the wall. Also make sure that the lifting height of the drain hose corresponds to the instructions (usually 60-90 cm). If the hose lies on the floor, a siphon effect may occur when water flows away by gravity during collection, or vice versa, back pressure is created.
- 🔍 Inspect the place where the hose connects to the sewer pipe: it may be clogged with food waste or hair.
- 💧 Check if the valve in the sink siphon is blocked if the drain is organized through it.
- 🧶 Make sure that the transport bolts (if the machine is new) do not affect vibration, which could dislodge the hose.
Users often forget to check the filter at the sewer connection point. If you have a special siphon installed for washing machines, a fat deposit could form inside it, which over the years narrows the passage opening. Cleaning this area will often restore normal water flow.
Use a bowl and a rag when disconnecting the drain hose from the drain. There is always about 300-500 ml of dirty water left in the hose, which can stain the floor.
Cleaning the drain filter: step-by-step instructions
If the external hoses are clean and Ariston washing machine does not drain water, in 80% of cases a clogged drain filter is to blame. This device traps coins, buttons, lint and threads, preventing them from getting into the pump impeller. Over time, this garbage can overflows and blocks the system.
The filter is usually located on the lower right side of the front panel of the machine, behind a decorative plug or hatch. Before starting the procedure, be sure to disconnect the machine from the power supply! The water inside the tank is hot and dirty, so prepare a low, wide basin and a cloth. Unscrew the filter slowly, allowing the water to drain into the container.
