Like any complex device, a washing machine can fail. There are often cases when, instead of draining the water and continuing the program, the machine stops and the message F05 is displayed on the screen. Error F05 on an Indesit washing machine clearly indicates a problem in the dirty water drainage system; there may be several reasons for its occurrence.
Reasons for error F05
Different washing machine models report the error differently. On devices with a segment indicator, F05 is displayed, in electromechanical models (without a display) the “Soak” and “Spin” lights blink synchronously, in some models the “Super Wash” and “Extra Rinse” lights up. Regardless of the signaling method, it is not difficult to understand what error F05 means - it is impossible to drain the water.
Error F05 can signal either a serious breakdown of the Indesit machine or poor care for it. There can be several reasons for this situation:
- the filter is dirty;
- the drain hose is clogged;
- sewer blockage;
- pump is faulty;
- The pressure switch has failed.
In very rare cases, the cause of error F05 is a faulty control module. There are two options on how to correct the situation; you can call a specialist, or you can figure it out yourself.
Cleaning the drain system
A fairly common reason for an Indesit machine not draining properly is the drain filter.It is designed to catch small items that accumulate during washing. Over time, threads, scraps of fabric, and buttons settle on it. Error F05 may appear precisely because of a dirty filter.
When eliminating error F05, before starting work, you must disconnect the Indesit washing machine from the mains and remove water from the drum. Accessing the filter is easy. It is located at the bottom of the machine, depending on the model, closed by a swing door or a removable panel. To remove the filter, simply turn it counterclockwise and pull it towards you.
Even though the water has been removed from the drum of the Indesit machine, it is a good idea to prepare a rag and a bucket. There is guaranteed to be some water left inside the machine.
The filter of the Indesit washing machine is washed under the tap and cleaned of accumulated dirt. Next, to eliminate error F05, check the drain hose. To do this you need to do the following:
- Loosen the hose fastening on the sewer outlet.
- Remove the hose and quickly lower it into any container to drain the remaining water.
- Rinse the hose with running water.
When checking and eliminating error F05, it will not be amiss to make sure that there is no blockage in the sewer system. If necessary, it can be cleaned with a thin metal cable or bent wire.
Malfunction of the pump or pressure switch
The appearance of error code F05 on the indicator may indicate a malfunction of the pump or water level sensor (pressostat) of the Indesit washing equipment. Checking these devices is a more difficult task; what to do: call a technician to repair the Indesit machine and eliminate error F05 or try to repair it yourself; again, it’s up to the owner to decide, but in any case, you should move on to the pump and sensor only after the filter and drain hose have been checked .
The remaining water is drained, the hose is disconnected, the filter is removed, then to eliminate the F05 error, do the following:
- Using a screwdriver, unscrew the bolts holding the pump.
- Carefully lay the Indesit machine on its side.
- Disconnect the pipes leading to the pump through the bottom.
- Remove the Indesit washing machine pump from the housing.
- Disconnect the supply pipe.
The removed parts of the drainage system must be carefully inspected for blockages, cleaned, and rinsed with running water. Particular attention should be paid to the condition of the Indesit washing machine pump. Structurally, it consists of an electric motor and an impeller. The cause of its failure can be either an electrical component or a jammed impeller.
To eliminate the F05 error, the Indesit washing machine pump is disassembled, thoroughly cleaned of dirt and scale. Using a multimeter in resistance measurement mode, measure the resistance of the motor windings. It is also worth making sure that the connecting terminals are in satisfactory condition; if necessary, clean them.
If the contacts are OK, and the device shows infinite resistance, the pump is replaced to eliminate the F05 error. This procedure is not particularly difficult, just buy a compatible device and install it in place.
Then the Indesit machine is assembled and run in test mode. If the F05 error is repeated, the cause of the breakdown may be the pressure switch. In Indesit machines, it is installed under the top cover.
To eliminate the F05 error, you need to access the Indesit machine sensor. To do this, you need to remove the cover. It is not difficult, you just need to unscrew two bolts on the back wall.The pressure switch of the Indesit machine is mounted on a corner bracket; it is a round part to which a hose and several wires are connected.
A malfunction of the pressure switch of Indesit washing equipment can be caused not only by sensor failure. Before buying a new one, you need to make sure that the tube through which pressure is supplied and the wires going to the control board are intact.
Control board fault
In rare cases, the cause of error F05 may be a failure of the electronic components of the control module board. This is the most complex and critical module of the Indesit washing machine; you can only undertake its repair if you have experience working with electronics.
If you have knowledge and confidence in the result, you should start eliminating the F05 error by removing the Indesit machine module and carefully inspecting it, preferably armed with a magnifying glass. It is necessary to ensure the cleanliness of the contacts and the integrity of the circuit components. The device diagram will help make the work easier. It can be downloaded from the Internet. The malfunction of some parts is visible to the naked eye, however, you must be prepared for the fact that in order to eliminate error F05 you will have to ring all the conductive paths and check all the radio components of the Indesit washing machine without exception.
