If all operating rules are observed, modern household appliances are ready to serve their owners for a long time and flawlessly. But sometimes the unexpected happens - the car suddenly begins to squeak like a “wounded animal.” This signal cannot be ignored; you must immediately find out why the dishwasher beeps while washing dishes. Service-Technician specialists will provide detailed advice by phone or via the feedback form on the website and suggest the optimal solution to the problem. If necessary, the master will arrive in a short time to any district of Moscow and the Moscow region.
When a “dishwasher” turns into a mouse - probable reasons
If for the housewife such a situation is force majeure, then for the ALM-remont specialists it is a normal case. The first step is to find out the cause of the squeaking noise, and then repair the dishwasher.
The reasons for a continuous beep can be very different:
- the filter (inlet or outlet) is clogged;
- the control unit is broken or the firmware needs to be reinstalled;
- there is a leak and the sensor has tripped;
- special products have run out (rinse aid, salt);
- The heating element has failed;
- the hoses are clogged or the pump is faulty;
- bearings “fly”;
Aquastop worked
Aquastop is a protective system that protects against leaks. It is available in many of the latest dishwashers from most manufacturers. For example, Bosch (Bosch), Hotpoint Ariston, Kandy, Siemens, Electrolux. On a number of models, data about the problem and the reason for the system operation is displayed in the form of error codes on the control panel. This makes it easy to determine the reason why the dishwasher beeps in the middle of the program. If the PMM does not have an Aquastop system, diagnostics are needed.
The door is not closed tightly
The device door is equipped with a lock that protects against leaks. If it is closed, the door lock signal is sent to the control module. After which the dishwasher starts working. When the lock is broken, the door cannot lock until it clicks. The module does not receive a signal about blocking; accordingly, the program will not start and water will not be drawn.
You can replace a broken lock yourself. To do this, disconnect the machine from the network, unscrew the front panel and the broken door lock. Then install a new lock and screw the panel back.
Filter clogged
To protect equipment from debris, food, and dirt, an inlet valve filter is installed. It needs to be changed or cleaned periodically. When water is slowly drawn into the machine or does not flow at all, the reason that the device begins to squeak is most likely due to a clogged filter. You can clean it yourself or call a professional.
Before cleaning, turn off the water. Unscrew the hose and remove the filter. It is located at the inlet of the intake valve. Rinse the mesh under running water. If there is a lot of dirt, then clean it with a needle or dip it in a solution of citric acid for 1 hour . The solution is prepared from 30 g of acid and 1 liter of water. The cleaned filter is installed in place and the hose is connected.
Sensor malfunctions
Dishwashers have different sensors that are responsible for monitoring the operation of all stages of the washing programs. With their help, the condition and level of water, temperature are controlled.
Let's look at typical error codes using the example of Electrolux dishwashers, which are caused by a malfunction of the sensors:
- 11 flashes (code ib0) – error in the turbidity sensor, which monitors the condition of the water using a light beam.
The reason is a clogged drain system, a failed level switch, or dirt deposits on the sensor. The problem can be solved by cleaning the sensor from dirt or replacing it.
- 13 blinks (code id0) – error in the tachometer, which regulates and controls the speed of the motor rotor.
A possible cause is burnout of the sensor winding or loose mounting due to vibration. There are several ways to solve the problem. First, check the sensor mounting. Secondly, the tachometer is replaced with a new one. Thirdly, check the resistance on the contacts, which should change when the motor armature rotates.
Water supply problems
The reason why the dishwasher whistles is not only due to breakdown. Sometimes there are interruptions in water supply. There may be no water supply in the inlet hose or water supply. A closed tap will also prevent you from using an automatic wash. All water supply options must be checked.
If the dishwasher is equipped with an electronic display, then along with the signal the system will show an error code. You can find out its decoding from the instructions for a specific model. This will make it easy to understand why the dishwasher beeps.
If such a problem occurs, you can check it yourself:
- power supply;
- floor and PMM for leaks;
- cleanliness of the pump and filter;
- Is the machine level, is there any unnecessary or unacceptable dishes in the chamber.
If after inspection there is no positive result and the dishwasher continues to beep, you should call a service center technician. He will conduct diagnostics and pinpoint the cause of the problem.
What you can do yourself
If the device is equipped with an electronic display, the system will generate an error along with a buzzer signal. You can find out the error code in the instructions for your dishwasher.
Without the threat of completely breaking the unit, follow these steps:
- check that the device is level, there is no overload of dishes or unnecessary items in the chamber;
- make sure that the power supply is ok;
- inspect the machine and floor for leaks;
- Make sure the filter and pump are clean and free of blockages.
The inspection did not yield anything, the “dishwasher” continues to squeak - call a professional! Only a specialist can accurately determine the cause of a sudden “strike”, and he will also correct the breakdown.

If the dishwasher does not turn on, it is better to carry out the initial diagnosis of this defect yourself. After the analysis, the confidence in calling service technicians will be well founded.
