Any technique that deals with the collection and discharge of water can fail, break down, and then there is a great risk of a “flood”. There can be many reasons for a leak in a dishwasher: sewer blockage, drain hose or filter, the pump or water supply valve has broken, and others. In most modern PMMs, there is a special system called Aquastop, which is designed to protect equipment from water leakage, regardless of the cause of the breakdown.
Waterstop - what is it?
Protection principle dishwasher from leaks in all PMM is the same, the same design as in washing machines. The Waterstop system is simple yet effective. It consists of a pan with a control float, a microcontact, a hose and a safety valve, which is attached directly to the plumbing system.
When water enters the pan as a result of a malfunction (about 200 ml), the float rises and closes the microcontact. The access of electricity to the safety valve is instantly stopped, and it closes, thereby blocking the flow of water to the PMM. Thus, the protection against leaks worked. Along with this process, water is pumped out.
Leak Protection Types
There are two types of water protection:
- complete;
- partial.
Which one is better? Complete protection against leaks in the dishwasher provides for a pallet with a control float and a hose with special valve sensors at both ends. As soon as the float has worked, cutting off access to electricity, the valves close, cutting off the water supply to the faulty machine. This design works and avoids flooding both in the housing and in the event of a leak between the hose inlet and the water supply. The full type is more reliable.
Important: if the leakage is insignificant, then the system will not immediately work in dishwashers budget option or earlier models. In modern dishwashers, Aquastop works instantly.
Partial protection against leaks is presented only in the form of a pallet with a float. The float through the microsensor sends a signal to the control panel, and the emergency mode starts, the PMM is blocked. That is, the hose and the space outside the machine remain unprotected when partial type. Thus, the answer to the question of which system is better becomes obvious.
Benefits of dishwashers with Waterstop
Today, there are practically no dishwashing equipment on sale without the Waterstop system. When buying a PMM, ask the seller what type of protection is present in the proposed models.
The importance and benefits of such a system from leaks in dishwashers can hardly be overestimated:
- in case of breakage and water leakage, your kitchen and floor will remain intact;
- it will not be necessary to compensate damage to neighbors in case of flooding;
- saving water, which simply overlaps when triggered;
- the ability to safely leave the PMM turned on at night or before leaving home;
- the ability to avoid even greater damage to the machine in the event of flooding and short circuits.
Protect yourself and your neighbors from unexpected flooding and damage to furniture with the Aquastop anti-leak system.
Modern dishwashers have leak protection systems called aquastops. Unexpected leakage from water hammer, bursting or worn seals can lead to significant costs, especially when neighbors are flooded. Therefore, such protection is very important for uninterrupted and safe work dishwasher.
Aquastop looks like a casing with a valve on the fluid supply hose. In the event of an unexpected change in pressure, it is triggered and the flow of water into the washing hopper stops. The simplest option is mechanically driven protection, which is also called external. Its effectiveness is slightly lower than alternative more technologically advanced options.
Types of protection
Depending on the price, the dishwasher can be installed different types aquastop. They have different design and operating principle. There are three options in total:
- Mechanical is the easiest.
- Mechanical with absorbent filler - more complex.
- Electromagnetic - the most technologically advanced and reliable.
Mechanical
This view is slowly fading away. Structurally is a plastic case on the inlet hose, inside of which a valve with a spring is installed. At normal pressure water is supplied normally. Its change causes the spring to actuate, which tightly blocks the outlet. The system is reliable, prevents leaks in 85% of cases, but is inferior to other options.
Mechanics with absorbent
The mechanical part consists of a plunger, a valve and a spring. For chemical component there is a special reservoir. Operating principle:
- when a leak occurs, water enters the tank;
- as a result of contact with moisture, the volume of the absorbent increases;
- a spring is activated, which presses on the plunger;
- the latter closes the valve.
A well-executed system provides almost 100% leak prevention.
The only drawback is the inability to reuse. After actuation, the filler hardens, and the hose with the casing needs to be replaced with a new one.
electromagnetic
This type gives 99% protection. It can be made in one-valve or two-valve version. The casing is complemented by a float tray, which is located at the bottom of the machine. The system turns on when water enters the casing. The following happens next:
- water flows into the pan;
- when it is filled, the float pops up;
- the lever raised by him closes the contact;
- solenoid valve shuts off the flow of water.
Signs of triggering
When the lock is activated, the water supply stops, the machine does not start the washing mode. But this situation can also arise for other reasons. Before drawing a conclusion about the state of the aquastop, you need to find out why it worked. To do this, it is necessary to inspect the filler section on the hose and check the condition of the pallet. In addition, in the event of a malfunction, an error code will appear on the display.
Error code
To inform the user about the status of the device, a display is provided on its front panel. The communication language of the machine consists of special codes that inform about errors. The models of the German brand Bocsh have the system activation code E15.
The meaning of the display is always written in the operating manual. But it is not always possible to check the cause of the operation through the value of the code.
Visual inspection
In situations where there is no indication, and the device refuses to work, it is necessary to examine the condition of the valve. Its tight contact with the inner edge of the nut is a sure sign of the activation of the leakage protection. For inspection you need:
- turn off the water supply;
- remove the hose with aquastop;
- make sure there is no gap between the valve and the fixing nut.
Pallet condition
On machines with electromagnetic protection additional way checks - inspection of the pallet. To do this, remove the lower protective bar from the front side of the device and check the tray for the presence of water in it. Its presence will confirm valve blockage.
Restoration of working condition
The advantage of mechanical protection is that it can be used repeatedly. After eliminating the cause and consequences of the leak, it is enough to cock the spring until it clicks and the device is ready for operation. Alternatives will require replacement of the hose. The procedure is simple and takes a few minutes. Necessary:
- Shut off the water supply.
- Dismantle the used hose with casing.
- Screw on a new one.
In the presence of an electromagnetic version, it will be necessary to connect the contacts of the casing to the recognition sensor. After that, you can resume the operation of the machine.
With an aquastop, a leak will almost always be fixed. However, its small probability still exists. To prevent a leak from becoming an unpleasant surprise, regularly inspect the dishwasher and the area around it for leakage.
Finding a puddle of water under the washing machine is extremely unpleasant, because you will not only have to repair the machine, but also pay for repairs to the neighbors you flooded. However, in case of water leakage, there is special protection and an aquastop system for washing machine. The methods of such protection should be considered in more detail and understand the disadvantages of each of them.
Protection Options
All washing machines, depending on the presence of a protection system, can be divided into three groups:
- cars without protection;
- machines with partial protection;
- machines, completely protected from leaks.
Most of the cars in the low and medium price category are not equipped with leakage protection. What does this mean? And the fact that water is supplied to the machine from water pipe through normal flexible hose with special nuts on both ends. The bottom of such machines, as a rule, is absent or closed plastic panel. And if the inlet hose breaks, then all the water in such a machine will flow out onto the floor. AT high-rise building a similar situation leads to flooding of neighbors from below.
So for this case it is recommended to turn off the tap for water supply after turning off the machine or install additional system protection on their own in the form of inlet hoses with valves, we will talk about them later. In some washing machines high-end protection already installed. For example, full protection from the flow of water is in cars under the brands:
- Asko;
- Ariston;
- Bosch;
- Siemens;
- miele;
- Zanussi;
- Electrolux.
Partial leak protection
What is partial protection, let's see how it works. Machines with this type of protection against leaks are equipped with a special drip tray, such as the one shown in the picture.
A float equipped with an electric switch is installed inside the pallet. The pallet is made of plastic or metal, the float is made of polystyrene foam. When water flows inside the machine, it enters the pan, with a certain amount of water, the float rises and the switch is activated. At his signal, the machine switches to emergency mode, the washing process stops, the pump works and pumps out water.
Important! In such a situation, an error code is displayed on the display of the machine, in different models there are different designations, for example, the E1 code will appear in the LG machine, and E9 in the Samsung machine.
If water leaks into the pan, you need to pour water out of it, and then look for the cause of the breakdown and eliminate it. About all possible reasons and fixing a leak can be found in the article on why the washing machine is leaking.
Inlet hoses with valves
Washing machines with partial protection are called so because the protection only works when water flows into the machine. But if the hose breaks in some place outside, then flooding cannot be avoided. In this case, it is worth considering inlet hoses equipped with protection. They are of three types:
Note! The Aqua Stop inlet hose is designed for a pressure of 70 bar, which is 7 times more maximum pressure in the pipeline.
Full protection against leaks - Aqua Stop system
Washing machines with full protection against water leaks have not only a tray with a built-in float, but also a hose with a solenoid valve, which we talked about above. In other words, if such a hose is connected to a machine with partial protection, then it can be called fully protected.
Such protection against leaks is considered the most reliable. Undoubtedly, cars equipped with the Aqua stop system have an advantage over conventional cars. Having overpaid several thousand rubles for it, you do not have to look for a high-quality inlet hose and figure out how to connect it correctly. The whole system has already been debugged by the manufacturer.
Note that the Aqua Stop protection is triggered in cases of leakage of the washing machine tank, damage to the nozzles, increased foaming and foam coming out.
In addition, full protection against leaks is accompanied by an emergency water pumping system. It works if for some reason the main and protective valve did not work. The main valve is the valve of the machine, to which the inlet hose with Aqua Stop protection is directly connected. You can read about how the main valve works and how to replace it in the article “Inlet solenoid valve».
Thus, the protection of the automatic machine from water leaks can be complete or partial. How to protect the premises from flooding, you choose. However, it is better not to save on safety, and at least install the Aqua Stop hose on the washing machine, which has a solenoid valve. Believe me, it's worth it!
The Aquastop system for the dishwasher is the necessary protection against leaks. All modern models dishwashers and washing machines are equipped with a full or partial security system.
Many users have heard about Aquastop, but not everyone understands the principle of operation and knows its device. In this article we will tell you what type of protection you need to choose equipment.
If your Electrolux, Hansa, Siemens dishwasher is equipped with partial protection, most likely it is the Aquastop inlet hose. It is equipped with a casing and a mechanism for shutting off water. When a leak occurs or the hose is damaged, the valve is activated and the water flow is blocked.
Aqua-Control will protect the system in case of water hammer. Whereas a system without protection may not withstand a lot of pressure.
In the new PMM models "Bosch", "Ariston", "Hans", "Electrolux", "Krona" you can find an improved device: in addition to the inlet hose, a float sensor is installed in the pan. How this scheme works:
- You turn the machine on.
- The Aquastop valve receives a signal and opens.
- As soon as you press the "Start" key, the membrane of the filling valve opens.
- Water enters the bunker.
- In the event of a leak, water enters the PMM pan.
- Upon reaching a critical point, a float sensor pops up.
- The valve closes, the flow of water stops.
The inner float is called Aqua Control.
Today, more and more manufacturers are trying to make PMM with a full "Aquastop". This is a guarantee not only for your safety, but also for your neighbors. Thanks to the functions of the system, you can safely run the equipment at night, go away on business while the dishwasher is running.
How to turn off Aquastop and restore the dishwasher? Once the problem has been corrected, press the reset key and the machine will be ready to work again.
Types and device
The design may be different. Manufacturers have developed several different ways which have their own advantages and disadvantages. Inlet hose protection is:
- Mechanical. Rarely used, but still found in inexpensive models Bosch. The design includes a spring and a valve. When a leak occurs, the pressure rises, the spring reacts to this and the valve closes.
A huge disadvantage of the mechanical Aquastop is that it is unable to catch small leaks. Without proper control, they can lead to flooding.
- using an absorbent. The method is somewhat similar to the previous one. If you disassemble the structure, you will see a valve, a plunger, a spring and an absorbent sponge. When a leak occurs, water enters the absorbent tank, which swells and triggers the spring. That, in turn, blocks the inlet to the hose with a valve.
The disadvantage of the absorbent system is very significant - it is disposable. If the "Aquastop" worked once, you will not be able to unlock and reuse the item. We'll have to completely change the protection.
- Electrical or electromagnetic. The hose is equipped with one or two valves and a protective sheath. Flowing down the casing, the water immediately enters the pan. There the float works and blocks the valve.
Interesting! The electronic and absorbent type system works in 99% of cases. Only 8 chances in 1000 that the car will leak. Mechanical protection works in 85%, that is, the chances of leakage are 147 to 1000.
You figured out what Aquastop is. Now we will find out what to do with a leak and how to replace it.
Do-it-yourself repair and replacement
When embedding appliances, users often encounter the difficulty of installing a protected hose. Its body is quite massive and does not fit everywhere, and it is impossible to increase the length. But once you've made the connection, how do you know Aqua-Control has worked and it's time to take action?
In Bosch machines, the error code E15 is displayed on the display. Explanation: overflow of water in the system or operation of "Aquastop". Then you can immediately check the design.
But if there is no error, and no water enters the hopper, you need to check the valve:
- Close the stop valve.
- Disconnect the hose from the PMM body.
- Look through the hole, you can shine a flashlight.
- If the valve is tight to the body, there has been a leak.
- Some models have a leak indicator.
Need more proof of a leak? Then look in the dishwasher tray. If there is water, fears have been confirmed.
Replacing and connecting the Aquastop is simple. Remember that the simple mechanical design does not need to be changed. Compress the spring until you hear a click. Everyone, continue to operate in the usual mode.
To replace, remove the old hose and screw on the new one. In the case of an electromagnetic system, connect the wire.
Take care of reliable protection your dishwasher. Please study before buying specifications, learn about the availability of complete or partial protection corps.
Water leakage protection will allow you to save a lot of money that will be required for the repair of your apartment and the apartments of your neighbors, who may suffer from water leakage as a result of a breakdown or damage to the inlet hose of the washing machine / dishwasher. To protect against the consequences of water leaks, it is necessary to turn off the water supply to the washing machine / dishwasher in time. But what if the accident happened in your absence? To prevent such a situation, a valve is installed on the water supply tap to the washing machine / dishwasher, which automatically turns off the water supply in the event of a water leak. The Aquastop safety valve automatically reacts to pressure drops in the washing machine/dishwasher connection system. Unlike electronic leakage protection sensors, Aquastop instantly triggers when the pressure in the system drops, does not require special skills during installation, is easy to use, is much cheaper than its counterparts, and does not require an electrical connection.
AQUASTOP UDI valve - the patented protective device of the company YUDI LLC is a water leakage protection system designed specifically for automatic shutdown water supply in the event of water leaks in the water supply system associated with a break / break in the inlet hose of a washing machine or dishwasher.
