Damage of a technical nature requires repair. These include faults of the following type:
– breakdown of the door locking system;
– damaged valve;
– broken water level sensor;
– malfunction of the control module;
– activated “aquastop”.
Each of the above breakdowns deserves detailed consideration. Having learned about them in more detail, you will be able to determine what to do if the dishwasher does not draw water.
The door does not lock
If you make sure that the door is closed tightly, but it does not lock, then this device is defective. The sensor will need to be replaced.
After turning on the equipment, a signal is sent to the valve. It opens, so that water penetrates into the household appliance. If the valve is damaged, the water supply will be stopped. It can break due to sudden changes in water pressure or frequent power surges. This element is not subject to restoration. If the valve is damaged, it must be completely replaced.
Faulty water level sensor
The task of this device is to measure the amount of water in the tank. Breakage of the water level sensor is accompanied by poor water supply or its complete absence. In this situation, you need to adjust the water supply level and the signal to the board.
Electromechanical installation for automatic dishwashing can be equipped with a water level sensor of the following type:
1. Electronic. It is a complex mechanism. It is possible to determine its breakdown only with the help of a tester with an error detection system.
2. Mechanical. It most often damages the membrane.
You can determine the fault of the sensor yourself. This breakdown has two characteristic features: there is little water in the tank or it is drained immediately after filling. In the first case, the quality of dishwashing will be significantly reduced.
Important! It is worth noting that the cause of the breakdown of the water level sensor is most often a clog in the pressure hose and poor fixation of the contacts, resulting in an increase in the temperature of the wiring.
The control module does not work
It is responsible for transmitting signals to other components of the machine. For example, to supply water, drain water, etc. That is, the control module is considered the “brain” of the dishwasher. If it stops sending the necessary signals, the equipment will not perform its tasks or will perform them incorrectly. For example, two buttons “Water” and “End” are simultaneously lit on the panel. That is, water is collected, and immediately this action is suspended. Such a breakdown can also be the reason why the dishwasher does not drain the water.
Depending on the type of breakdown, the control module may need to be repaired, flashed, or replaced. It is strongly not recommended to carry out any manipulations with the board yourself. It is better to contact North Country Appliance Repair Company. This requires special equipment, tools, and skills.
This is the protective system of the unit. It can be the reason why the dishwasher does not draw water. The task of the protective system is to prevent leaks. To avoid them, the electric drive closes the tap. As a result, water stops flowing into the unit. If the equipment hums at startup, but the water is not collected, then you should inspect the “Aquastop”.
The protective system is an element located on the hose that supplies water. If the hose is damaged, the “Aquastop” is triggered. Be sure to check it for defects. If they are found, replace the hose. It should be borne in mind that in some cases it is necessary to replace the protective system itself, as it may fail during operation.
Recommendations to prevent breakdowns that cause the dishwasher not to draw water
To extend the life of the unit, you must follow a few simple rules:
1. Timely carry out all routine maintenance in accordance with the manufacturer’s recommendations.
2. Use only high-quality detergents from trusted companies.
3. Follow the rules for installing and connecting equipment.
4. Install a filter to prevent large organic matter from entering the water supply system.
5. If the unit is not in use, turn off the water supply. This will minimize the risk of valve breakage.
By following simple recommendations, you can avoid serious breakdowns. When you first start the dishwasher, be sure to read the operating instructions.
Now you know why the dishwasher does not draw water. Breakdowns of a non-technical nature can be tried to eliminate on their own. In case of serious malfunctions, contact a North Country Appliance Repair Company specialist.
If you still did not manage to recognize the cause of this breakdown by all the points provided above, or if you do not want to waste time guessing, North Country Appliance Repair Service is always happy to help you and provide a professional diagnosis and repair of your dishwasher in a timely manner.
