The self-diagnosis system in washing machines Ariston tells us how to identify and fix the problem. If the F04 error is displayed on the Hotpoint Ariston electronic models, this indicates a malfunction of the water level sensor.
Ariston's electromechanical washers notify of a malfunction code by indicating: the "Empty tank" - "Overflow" light is on.
What error F04 means: how to determine the problem
To remove the error F 04 and find out the cause of its appearance, you need to perform several sequential actions:
- To eliminate a system failure and reset the error, unplug the SM Ariston from the outlet. Turn it on after fifteen minutes. If the error appears again, read on.
- Check the connection between the electronic module and the pressure switch: the contacts may have come loose.
A pressure switch is a device that controls the amount of water in a tank. If it fails, you will notice obvious signs:
- Washing Ariston (Hotpoint Ariston) is collecting excess water.
- The machine takes too little water.
- Lingerie is poorly wrung out.
- A common problem is when the machine’s tank is empty, but the system believes that it is full of water. TEN works idle, as a result of which it can quickly burn out.
- In the "Rinse" mode, the drain pump is switched on.
Now you know what a breakdown of the water level sensor can mean, in which the machine shows error code F04 on the display.
Before proceeding with the repair, the pressure switch must be checked.
What to do for inspection and repair
In the Ariston washing machine, the pressure switch is located at the top of the side panel. To get to it, you need to open the top cover of the washer. For this:
- Disconnect SM Ariston from a network.
- Turn off the water, disconnect all communications and hoses.
- Remove the two bolts and slide the top panel to the side.
- The location of the level sensor is shown in the photo.
- Remove the clamp with pliers before removing the pressure switch.
- Connect a small length of hose and blow into it.
- A working pressure switch will emit from one to three clicks, which indicates a program switch.
- If nothing happens, check the connections and wires.
- Inspect the sensor hose for clogging. If necessary, clean to solve the problem.
To replace the pressure switch, you must purchase a new device and install it in place. Repair can be done independently, the main thing is to carefully consider the details.
Now, if Ariston's washing machine generates an F 04 error, you know how to troubleshoot.
