Error F04 in the Indesit washing machine – how to fix it yourself

What does error F04 mean, which is shown on the display by the Indesit washing machine? On the electromechanical model, the indicators “Super Wash” and “Soak” are lit.

The point is a malfunction with the water sensor (pressure switch), which gives incorrect signals. A breakdown can be expressed in a lack of water level or a failure in the operation of the washer after starting.

Error code F04 – signs of sensor failure

Each Indesit washing machine has a water level sensor (in the circles of repairmen – a pressure switch). The device allows you to adjust this level in the tank (high, medium, low) protecting it from overfilling.

When error F 04 is displayed on the display, you can conclude that the pressure switch is broken by the signs:

• Washing and heating starts without water in the tub.
• The tank is full (the water level in the loading hatch is more than 1/2), or, conversely, there is clearly not enough water for washing.
• In case of an error, including the “Rinse” mode, the water is alternately pumped out, then supplied.
• The heating element fuse has tripped, there is a smell of burning.
• Linen is not wrung out.

Before replacing the pressure switch, it must be checked. After all, these signs can be the cause of breakage and other parts.

Have you noticed similar signs in your Indesit machine? This is an occasion to check the sensor for serviceability.

What to do to check the sensor with error F04

How to fix F04 error in Indesit washing machine? The solution to a problem lies in its correct definition.

1. Check the operation of the water supply tap, whether it enters the machine normally.
2. Check the fill valve filter for blockage.

To reset the F04 error, try restarting the washer by unplugging it from the mains.

What to do if these actions did not lead to anything and the error code is still on the scoreboard? Then you need to get to the pressure switch:

1. Unscrew the bolts, remove the back panel of the machine.
2. The device is located on the side panel. It is necessary to disconnect the wires and hose attached to it.
3. Unscrew the bolts, remove the sensor.

Inspect the instrument for damage, oxidation or blockage.

• Blow on the pressure switch. Clicks should be heard – three clicks are possible (depending on operating modes). If nothing is heard, the pressure switch is faulty.
• Check the sensor with an ohmmeter tester. The resistance should be more than 20 ohms.
• Inspect the contacts of the pressure switch module for integrity.

Independent solution of the problem

You will learn how to remove the F 04 error in the CMA Indesit with your own hands.

If during the check your fears were confirmed, and the pressure switch is faulty, a replacement will be required. Repair is not considered as the sensor housing is not disassembled. Select a new part, taking into account the brand and model of the Indesit washing machine, the volume of the loading drum.

• Attach the part in place with screws.
• Connect the hose to the fitting, firmly fasten the clamp.
• Connect the contacts in place.
• Close the cover, tighten the screws.

Now you know what it means when an Indesit washing machine gives error F04 and how to fix it.

To check, connect the washer to the mains and wash it empty several times, trying different modes. If it does not show trouble codes, then you have dealt with the breakdown.
