Error F03 in the Indesit washing machine

Error F03 in the Indesit washing machineModern Indesit machines in the event of breakdowns themselves diagnose the problem and display a specific code. Having deciphered the combination, you can not waste time searching for the cause, but immediately determine the source of the trouble. The main thing is to correctly interpret the "message" from the system. So, error F03 on the Indesit washing machine means that the thermal sensor or heater is faulty. What to do in this situation - we will tell below.

We identify this code

If the display of the Indesit washing machine gives an error “F03”, then the machine cannot heat the water to the desired level. The time allotted by the system for heating ends, the control board does not receive information about the executed command and pauses the started cycle. Washing can continue only at low temperatures. The washer shows the code “F03” when one of two malfunctions occurs:

  • the relay of the heating heater has stuck;
  • the temperature sensor has broken.

The error “F03” can also manifest itself on machines without a display. Then the “Revolutions” and “Quick Wash” or “Revolutions” and “Extra Rinse” lights on the dashboard will simultaneously flash. Another bad symptom is the cold glass of the hatch door during the washing phase. To correct the situation, you must first establish the exact cause.

How can I fix the malfunction?

It is pointless to operate the machine with a similar problem. The wash will not be of high quality, and the system will be “buggy” due to a mismatch in the teams. Therefore, turn on the rinse and check the performance of the machine. We act like this:

  • empty the drum from the laundry;
  • reset the error and disconnect the machine from the network;
  • wait 15-20 minutes and reboot;
  • we call through a multimeter a bunch of resistors on the control board of ratings of 180-220 kOhm;
  • we check the temperature sensor with the tester, normally the reaction to heating from +20 degrees is more than 20 kOhm.

People who are not versed in electronics, it is better not to experiment and immediately turn to professional masters.

Diagnostics is completed by visual inspection of the heater circuit and the control circuit. If obvious insulation damage, signs of burning, or loose contacts are visible, then repair with replacement parts is necessary.

Reasons for lack of heating

faulty heaterThe error "F03" can be suspected by the Indesit typewriter even before it appears on the display. There is a definite symptom - the washing machine stops heating water. Cold things in the drum after the end of the cycle or an unheated hatch door 15 minutes after the start will tell about this. Then it becomes clear that the machine does not heat up to the set temperature. To repair the unit, we first carry out the diagnostics. The reasons for the lack of heating can be quite a lot.

  1. User Error. Probably, the mode with the lowest temperature was initially selected. The solution is to control the cycle with the new program.
  2. Clogged pressure switch. During operation, the sensor tube becomes clogged with threads, hair, and small debris. This leads to incorrect recognition of the level of accumulated water, more precisely, the pressure switch does not give a signal about the set, because of which the system can not give a command to heat.
  3. An open circuit in the heating element. Carefully inspect the wiring led to the heater. If there are signs of damage - replace.
  4. Faulty heater. Larger damage due to scale or wear. The answer to “what to do?” Is simple: we call and, if necessary, replace it with a working analog.
  5. Broken temperature sensor. We remove the back cover, remove the bracket and release the wiring. Next, use a screwdriver to unscrew the shield, nut and change the sensor.
  6. Defective TENA relay or programmer. The reason is overstrain and factory defect.

Trying to repair the TEN relay yourself or the board is not worth it. These mechanisms are very complex and sensitive, and the experiment will result in an expensive replacement. It is better to immediately contact the master.
