Error F-05t, F5 in the ARISTON washing machine

Although the ARISTON washing machine is renowned for its dependability, problems can occasionally arise with any appliance. F-05 or F5 error codes are among the most frequent issues users run into. This indicates that there is a problem that needs to be fixed before you can finish your laundry if it has appeared on your machine.

Gaining an understanding of the F-05 or F5 error and how to resolve it can help you get your washing back on track while avoiding needless repair expenses. This tutorial will describe the meaning of these error codes and offer easy solutions.

When ARISTON washing machines display error codes F-05 and F5, it usually means that there is an issue with the machine’s ability to drain water. A few simple troubleshooting techniques should usually be able to resolve this issue, which is frequently caused by a clogged filter, a blocked drain hose, or a malfunctioning pump.

What does error f05 mean in an Ariston washing machine

When the Ariston washing machine shows the code f05 on the screen after a while, it indicates that there may be an issue transitioning from the washing to the rinse or from the rinse to the spin modes.

In this instance, the machine ends the designated program; however, in the majority of these errors, the water stays in the tank. An electronic module controls the various components and units that make up the washing machine.

In turn, the electronic module executes a predetermined program based on the data from a few sensors that tell it how the washing cycle is being carried out in its entirety. The pressure switch is one of these sensors. This unit is in charge of keeping an eye on the water level in the tank and alerting the control unit when the used cleaning solution has been completely drained.

The electronic unit stops the washing machine and displays the error code if the pressure switch provides any incorrect readings that do not match the program. In the event that code F05 is present but there is no water drain.

Reasons for the occurrence of the error f05 on the Ariston washing machine

There are several causes of Ariston washing machine error F05:

• Electronics can sometimes fail due to inappropriate voltage in the power supply network or failure of some electronic components that make up the entire control unit.
• It is best to let a specialist in this area of ​​​​repair cope with such a malfunction.
• Independent attempts can lead to additional financial costs for the purchase of a new expensive module;
• A common cause is a clogged drain system.

It happens in various locations along the drain line:

• In the pipe from the tank to the drain pump. Small things that were pulled out of the drum during washing can make an obstacle to draining water. Such items may be children"s clothes, socks, handkerchiefs, parts of candy packaging, etc.;
• In the drain pump filter. This filter element is designed to prevent foreign objects from entering the drain pump to avoid jamming. Gradually, many toothpicks, cotton swabs and clothing accessories accumulate in the filter. With their accumulation, the passage of drained water into the sewer is difficult and when the drain command is given, the F05 code appears on the Ariston washing machine;
• Malfunction of the drain pump itself. The drain pump in washing machines includes a "wet rotor" in its design, rotating on bushings directly in the drained water itself. Due to the strong hardness of the water, the shaft and bushings wear out and the rotor jams in the stator. This may happen at first unnoticed by users due to the pump operating "every other time".
• The machine can perform the washing mode without fail and switch to rinsing, but refuse to drain the water completely on one of the rinses and the module will receive positive readings from the pressure switch. But experienced housewives begin to notice poor washing quality with such incorrect operation of the pump, which then completely fails and the f05 code appears. A piece of a toothpick that has passed through the filter can also be the cause of the pump impeller jamming.
• Threads from clothes can also get wound around the pump shaft;

• Clogged drain hose. It occurs gradually by the build-up of scale deposits on the inner walls, gradually narrowing the passage for draining water. Weak points are the joints of the hoses and sewerage, in these places the internal diameter is smaller than usual and becomes overgrown with scale faster. When connecting the drain of the washing machine to the siphon of a sink or washbasin, the siphon sump may become clogged;

• One of the common causes of the f05 error in Ariston washing machines is a clogged hose from the tank to the pressure switch. It has a small internal diameter and carries only the function of transmitting the resulting pressure to the pressure switch when filling the tank with water and vice versa when the pressure drops during draining the waste solution. A clogged hose prevents the pressure in the level sensor from dropping and it does not generate a signal to the control unit about the complete draining of water that the pump has already removed into the sewer;
• A rare but common cause is loss of contact due to a break in the wiring or oxidation of the connecting terminals.

Ways to eliminate the f05 error in the Ariston washing machine

The following steps should be followed in order to determine the cause if you choose to fix the Ariston washing machine’s f05 error on your own:

• First of all, disconnect the machine from the electrical network;
• Then move it away from the wall so that by tilting it back you can put a container (in the form of a bowl or basin) under it with a volume of about 7-10 liters and unscrew the drain pump filter. The water will drain from the tank, pay attention to the presence of foreign objects in the filter, water in the container and in the sink itself (from which the filter was unscrewed);
• In the sink, the pump impeller in the form of a cross is freely visible. Scroll it and make sure it rotates freely;
• If the water does not drain from the tank when dismantling the filter, then the blockage has formed directly in the pipe going from the tank to the drain pump. It is necessary to remove it and clean it from things that have gotten there;
• If the pipe and filter are clean, the pump impeller rotates freely, then check the drain hose from the pump to the sewer. This can be done from different ends with air pressure or water from the water supply. If the hose is connected to the sewer through the sink siphon, check the siphon sump and clean it;
• Check the pressure switch tube with air pressure, also inspect the pressure switch contacts for oxidation;

• If all the actions taken were unsuccessful, then dismantle the drain pump. To do this, unscrew it from the body of the washing machine together with the filter, remove the hoses and wires from it, and take it out. Then we disconnect it from the filter housing. We check the resistance of the stator winding with a multimeter, it should be within 170-230 Ohm. We check its shaft for transverse play by shaking the impeller. If possible, you need to remove the rotor from the pump and check for wear on the shaft. If wear is visible, the pump should be replaced.
• The fact is that mechanical wear on the shaft and bushings provokes the rotor to jam in the stator, and this can happen at the initial stage of wear far from every time the drain is turned on. The malfunction of the drain pump can only be eliminated by replacing it with a new analogue, the original part is best suited. Moreover, there are few manufacturers of decent quality drain pumps today.

It can be annoying to see the F-05 or F5 error code on your ARISTON washing machine, but keep in mind that drainage problems are frequently the cause of these errors. You can swiftly restore your machine’s functionality by locating and fixing the underlying issue.

The most frequent culprits are blockages in the drain hose and pump filter, so start there. Eliminating them could potentially solve the issue without requiring additional assistance.

If none of these easy solutions resolve the problem, there may be a more complicated problem, like a broken pump or a broken pressure switch. In these situations, seeking professional advice might be essential to prevent future issues.

By ensuring smooth operation and extending the life of your appliance, you can help prevent these errors in the future by keeping your washing machine well-maintained and doing routine checks.
