All Indesit washing machines have a lock indicator on the dashboard. In normal mode, it lights up red only during washing. After the hatch is unlocked, the lock lamp turns off. If the indicator is constantly on, something in the equipment has failed. In this case, it is diagnosed.
We check the machine according to the algorithm
First of all, it is recommended to exclude the influence of external factors on the technique. If the red light on your washing machine is on, make sure it is filling with water! In some cases, failure to start a household appliance may be a consequence of low pressure in the water supply system or interruptions in the operation of the centralized water supply.
In this case, the ECU receives a signal that it is impossible to draw water. It, in turn, signals the need to turn on the lock indicator. If the “overheating protection system” does not work, the heating element ignites, followed by the tank of the household appliance.
The washing machine won't wash? Check for power outages! The “Achilles heel” of Indesit washing machines is that even the smallest surges in the power supply network can lead to a software failure. As a rule, eliminating such an “error” is easy:
disconnect the machine from the power supply;
wait 10 – 20 minutes;
We connect equipment to the network;
select the “Drain and Spin” mode.
If the red lock light comes on again, the problem requires more serious consideration.
In most cases, the problem of malfunctions in the operation of the lock indicator is solved at the stage of primary diagnosis.If this does not happen, proceed to testing the components of the household appliance. First, the mechanical parts are checked, then the quality of the equipment’s electronics is assessed.
Level sensor and heater
The reason for failure to start Indesit washing machines may be a breakdown of the pressure switch. So, if after a while after the start of water intake it does not give a signal that the tank is full, the equipment stops working. The water supply stops. An error appears on the machine display.
For reference! The water level sensor is located under the top cover, on the right side of the body of the household appliance.
In this case, water meter diagnostics are carried out from simple to complex. First, the possibility of mechanical damage to the tubes and housing is eliminated, then blockages are eliminated, and then the quality of the adjustment and the reliability of the contacts are assessed. If the pressure switch breaks down, it is replaced.
The red light on the lock may light continuously even if the heater is broken. In this case, it can be difficult to immediately identify this problem. The equipment continues to wash things even in cold water (only the risk of fire and current leakage to the body of the household appliance increases). To determine how the heating element works, it is necessary to perform a number of actions.
Remove the back panel.
Inspect the wiring.
Perform resistance measurements.
If the final indicators deviate from the norm, you should purchase and install a new heating element. You should get rid of the old one.
Blame it on the electronics
Malfunctions in the operation of Indesit washing machines can be caused by a failure of the control board. Even if the signals of the UBL, pressure switch, and heating element are sent to it, they are not recognized.There are many reasons for electronics failure (moisture on contacts, voltage surges, software failures, etc.).
What to do in this case? Contact our service center specialists for help! It is too risky to independently diagnose or repair the board, as well as other mechanisms of an electronic household appliance.
