Error code f05 in an Ariston washing machine

In an Ariston washing machine, error code F05 may appear on the display after the machine has finished washing the laundry, but water is still in the drum. If the cause isn't corrected, the error will reappear even before the wash cycle starts. In this article, we'll decipher the F05 error code, identify possible causes, describe the troubleshooting process, and provide troubleshooting tips.

Why does error f05 appear in a washing machine: what does it mean?

Before we explore the possible causes of the F05 system error, let's decipher it. It literally means the following: the drain pump is not functioning, or the pressure switch cannot determine the presence or absence of water in the tankUntil the cause of the error is resolved, the system stops issuing a command to fill the tank and pauses all programs. What causes error code F05 in an Ariston washing machine?

• There is a blockage in the filter, drain hose, trap or sewer pipe that is preventing water from draining from the washing machine tank.
• 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.
• The drain pump inlet valves are faulty.

Depending on the underlying cause of the F05 error, the system may return an F11 error after restarting the machine. In this case, it's safe to assume the drain pump sensor is the issue. However, this specific error doesn't always occur on all Ariston washing machine models, although it's worth trying to restart the system several times. You can find a detailed breakdown of other system errors returned by Ariston washing machines in this article. Ariston error codes.

Please note! To effectively restart your Ariston washing machine, you should not only turn it off using the on/off button, but also de-energize by pulling the plug out of the socket for 30 seconds.

How to find the cause: step by step

If your HotPoint Ariston washing machine displays error code f05, you need to take steps to identify the problem, as there could be many possible causes, as we've already noted.

To quickly find the cause of error f05 without damaging your washing machine, follow a specific procedure. The preliminary steps are as follows.

1. If the machine displays an error during the wash cycle, turn it off using the button and then disconnect it from the power source. Repeat this procedure 3-4 times. If the system still displays error code f05, proceed to the next step.
2. We check the sewer system for blockages (we turn on the water more strongly and check how it drains).
3. Turn off the machine and drain the water from the tank through the emergency drain hose. The hose is located at the bottom of the machine near the debris filter.
4. Unscrew the filter plug and remove any dirt or debris from the hole, then replace the plug and plug the emergency drain hose. After this, you can turn on the machine and run the wash cycle again. If the F05 error persists, proceed to the next step.
5. Disconnect the drain hose from the trap and check it for blockages. If the hose is clear, proceed to the next step.

Important! You can skip these steps if the display shows error f10 or f11 after turning the machine back on.

6. We unfold the washing machine, open its casing, and locate the drain pump. Armed with a multimeter, we check the voltage at the drain pump contact, as well as the pressure switch (water level sensor). If the sensor contacts are secure and there is sufficient voltage, we proceed to the next step.
7. We'll purchase a new pressure switch for our Hotpoint Ariston washing machine and replace it. If the error persists, the drain pump will need to be repaired or replaced.

Experts advise against rushing to replace the drain pump yourself, but to have the electronic controller tested. It's highly likely that this is the problem, especially since it's quite difficult to diagnose a faulty drain pump on your own. Contact a specialist who will test the system for faults and also inspect the drain pump.

The source of the error has been detected – how to fix it?

Let's be clear: it's impossible to fix every cause of the F05 error on your own. However, in most cases, you can avoid unnecessary expense and calling a specialist. The easiest way is to clear clogs from filters, hoses, and the drain pipe. The drain hose can be flushed with a powerful stream of hot water, and the drain pipe can be cleared with liquid drain cleaner or a long steel wire.

The pressure switch and drain pump sensors are more complex. Checking their voltage requires basic multimeter skills. Furthermore, you should first study the table that provides information on the voltage supplied to specific components for your specific Ariston washing machine model. Then, test these components one by one with a multimeter and compare the resulting values ​​with the table.

Chances are, you won't want to deal with such things, or you'll simply be afraid to mess with the insides of your washing machine. In that case, don't rack your brain; contact a specialist who can quickly resolve the F05 system error. Wishing you a successful repair!

   Vladimir:

   Thank you. The description helped clear a clog in the hose—the corrugated tube from the tank to the drain pump. I had some thin women's panties stuck in there, it happens sometimes when they want to flush. 🙂 I'll continue washing. All the best to everyone.
