Reading the description of the dishwasher, among other characteristics, you may come across the “Aquastop” option. As the name suggests, this function stops the flow of water into the system. Let's figure out in what cases protection is activated and how it works.
Why is this system needed?
The pipes through which water enters the apartments have quite high pressure. In addition, cases of water hammer are not uncommon. All this can provoke an emergency leak. The aquastop option in the dishwasher is necessary in order to protect the equipment from leaks.
The principle of operation of the protective system in dishwashers is the same as, for example, in automatic washing machines. Having detected a leak, the equipment blocks the flow of water, and in some cases additionally starts draining. All this helps to avoid flooding both your own and your neighbor’s apartment.
The Aquastop system, according to statistics, in 99.9% of cases helps to avoid significant damage from leaks. The probability that the function will not work is very small. However, one hundred percent protection cannot be guaranteed, so you must do your best to protect yourself from possible problems.
What measures should dishwasher users take to protect the appliance from leaks?
Clean your dishwasher filter regularly.
Wash the gel cuvette regularly to prevent the tray from becoming clogged.
Check the integrity of the rubber seals.
Use only high-quality detergents designed specifically for PMM.
The Aquastop system in PMM can provide full or partial protection against emergency leaks.
How can a protective system be organized? How exactly does a dishwasher detect a leak and block the water supply? Let's look into the nuances.
Technical solutions Aquastop
Today, almost all dishwashers have the Aquastop option. Budget devices are equipped with a tray with a float; models from the middle and high price segments are additionally equipped with an inlet hose with a special sensor. In the first case, protection against leaks is considered partial, in the second – complete.
Partial protection is the easiest way. In this case, a special tray with a float is provided at the bottom of the dishwasher. An electrical sensor is built into the foam. If water begins to accumulate under the machine, the ball will float. When it rises to a certain level, the protective system is triggered.
The sensor will instantly send information to the control board. The dishwasher will stop working and the cleaning cycle of plates and mugs will be interrupted. Next, the drain pump is activated - it will pump water out of the device.
To continue using the dishwasher, you will have to remove the tray and empty the water from it. Then be sure to identify and eliminate the cause of the leak. If you do not want to diagnose the device yourself, contact the service center for help.
Absolute protection is recognized as the most modern. You can find it on models in the middle and high price segments. In such dishwashers, in addition to the tray, there is an inlet hose with a special solenoid valve.
Magnetic valves open when water enters the chamber. When the machine is filled to the desired level, the sensor transmits information to the module and the inlet membrane automatically closes. Due to this, overflow is avoided.
If the inlet hose is damaged, or the water level sensor or drain pump breaks, then a pan with a float comes into play. He is the second stage of aquastop. Due to multi-level protection, leaks can be avoided.
If the aquastop function works, you will also have to empty the pan and start troubleshooting. Having identified what caused the leak, fix the breakdown. Only then can you start using the dishwasher again.
Experts recommend buying dishwashers with complete, absolute protection against leaks.
Models equipped with an inlet hose with an electromagnet and a tray provide both internal and external protection, minimizing the risk of overflow when drawing water into the machine. Therefore, if possible, it is better to pay attention to such dishwashers.
What to do if leakage protection is activated?
What to do if the aqua-stop in the dishwasher has worked? What should the user do first? The activation of the protective system may occur if:
the drain pump has failed;
the sewer pipe is clogged;
the garbage filter is clogged;
water is drawn into the machine in jerks (this may indicate that the inlet hose is pinched);
the seal of the dishwasher chamber is broken;
the washing machine door was damaged;
impeller damaged, etc.
If you discover that the Aquastop system has activated, immediately turn off the power to the dishwasher.
If a puddle has formed near the machine, it is important to avoid contact with water. Stepping on a wet floor can result in an electric shock. If you cannot reach the outlet and unplug the cord, then turn off the electricity in the entire apartment at the panel. Next, you should stop supplying water to the dishwasher. If there is a shut-off valve installed in the pipe in front of the machine, turn it.If not, then turn off the valve on the common riser.
Then you will have to pour the water out of the pan and start troubleshooting. If the filters are clogged, it will be enough to clean them. If the inlet hose is damaged, the part must be replaced. Sometimes a leak occurs due to a low-quality detergent that creates too much foam in the chamber. Once you have identified the problem, take steps to correct it.
After repairing the dishwasher, you need to reset the settings. The Aquastop function is then activated again. If the problem is in the leakage protection itself, then you will have to replace it.
