Error f05 in the washing machine Ariston

In the Ariston washing machine, error f 05 may appear on the display at the moment when the machine has already washed the laundry, but the water is still in the tank. Subsequently, if the cause is not resolved, the error will appear again even before the start of the washing program. In the framework of the article, we will decipher the error f05, identify the possible reasons for its occurrence, describe the process of searching for the causes of the error, and formulate tips for eliminating these causes.

Why the error f05 appears in the washing machine: what does it mean?

Before finding out the possible causes of a system error with code F05, let's decrypt it. It literally means the following: the drain pump does not work, or the pressure switch cannot determine the presence or absence of water in the tank. In the future, until the cause of the error is eliminated, the system ceases to give a command to fill the tank with water and pauses all programs. What causes error f05 in the ariston washing machine?

• There is clogging in the filter, drain hose, siphon or sewer pipe, which prevents the drainage of water from the tank of the washing machine.
• There is no voltage to the pressure switch sensor, or it is faulty.
• There is no voltage to the drain pump sensor, or it is faulty.
• Defective inlet valves of the drain pump.

Depending on the initial cause of the error f05, the system, after restarting the machine, may give an error f11 in this case, we can say with confidence that the matter is in the sensor of the drain pump. But the clarified error “pops up” not in all cases and not on all models of ariston machines, although it’s worth trying to restart the system several times. A detailed decoding of other system errors generated by the Ariston washing machine can be found in the article Error codes Ariston.

Note! To effectively restart the Ariston washing machine, you should not only disconnect it from the on / off button, but also disconnect power by pulling the plug out of the socket for 30 seconds.

How to find a reason: step by step

If the hotpoint ariston washing machine generated an error f05, measures must be taken to detect the malfunction, because there can be many reasons, as we have already noted.

To quickly find the cause of the error f05 and not harm the washing machine, you need to follow a certain scheme. At the preliminary stage, you need to do the following.

1. If the machine generated an error during the washing process, it is necessary to disconnect it from the button, and then turn off the power by disconnecting it from the power supply. The procedure should be carried out 3-4 times, if the system still continues to generate an error f 05, go to the next step.
2. We check the sewer system for blockages (we open the water harder and check how it leaves).
3. Turn off the machine and drain the water from its tank through the emergency drain hose. The hose is located at the bottom of the body near the trash filter.
4. We unscrew the filter plug and remove dirt and debris from the hole, then twist the plug and plug the emergency water drain hose. After that, you can turn on the machine and run the washing program again. If the error f05 repeats, go to the next step.
5. Disconnect the drain hose from the siphon and check for clogging. If the hose is clean, go to the next step.

Important! These steps can be skipped if, after switching on the machine again, the error f10 or f11 is displayed.

6. We expand the washing machine, open its body, we find the drain pump. We arm ourselves with a multimeter and check the voltage at the contact of the drain pump, as well as the pressure switch (water level sensor). If the contact of the sensors is reliable, and the voltage is sufficient, proceed to the next step.
7. We purchase a new pressure switch for the hotpoint ariston washing machine and make a replacement. If the error continues to flash, it means you have to repair or replace the drain pump.

Experts advise not to rush to independently change the drain pump, but to order testing of an electronic controller. It is very likely that the problem is precisely in it, especially since it is rather difficult to independently determine the failure of the drain pump. Contact a specialist who will test the system for malfunctions and at the same time look at the drain pump.

Error Source Detected - How To Fix It?

We warn you right away, absolutely all causes of the error f05 cannot be eliminated on your own. Nevertheless, in most cases, you can do without unnecessary costs and call a specialist. The easiest way to clean filters, hoses, and sewer is from clogging. The drain hose can be flushed with a powerful jet of hot water, and the sewer can be cleaned with a liquid pipe cleaner or a long steel wire.

More complicated is the situation with the sensors of the pressure switch and the drain pump. In order to check the voltage on them, elementary skills of working with a multimeter are required. In addition, you must first study the table, which sets out information about the voltage supplied to specific nodes, a specific model of the Ariston washing machine. And then, in turn, check these nodes with a multimeter and compare the resulting values ​​with the table data.

It is very likely that you will not want to do such things, or you are simply afraid to climb to the "insides" of the machine. In this case, do not rack your brains, contact a specialist who will quickly solve the problem with system error f05. Good luck with your repair!
