Error E4 on Candy dishwasher

Error E4 on Candy dishwasher Modern dishwashers themselves notify users about problems in the system. Error E4 notifies that Aquastop has been activated. How to fix the problem? Do I have to call a technician, or can I reset the code myself? Let's look into the nuances.

What do we do when code E4 appears?

Candy dishwashers report the activation of the Aquastop system in different ways. Some display an error code on the display. For models without a digital display, certain LEDs on the control panel light up. The indicator on the PMM inlet hose also changes color - it acquires a reddish tint.

Study the instructions for your Candy dishwasher, this will give you an understanding of how the equipment informs you about the operation of Aquastop.

What should I do to reset error E4? It is necessary to determine where the leak is coming from. First, inspect the dishwasher inlet hose; if the indicator on it turns red, most likely the corrugation will have to be replaced.

The Aquastop system sensors are different. If your dishwasher has a mechanical one, then it is not necessary to change the hose. It will be enough to loosen the spring and push the membrane of the device inside. aquastop in the dishwasher tray

The inlet hoses of modern Candy dishwashers cannot be reused after the Aquastop has been activated. In such a situation, you will have to replace the corrugation. Therefore, everything depends on the type of leakage protection system sensor.

Replacing the PMM inlet hose is very simple. Necessary:

turn off the power to the dishwasher;
turn off the tap responsible for supplying water to the machine;
unscrew the old hose first from the PMM, then from the connection point to the water supply;
connect a new hose.

If the Candy dishwasher is equipped with electromagnetic protection, then you will additionally need to connect the wire to a special sensor that recognizes leaks. The groove for connecting the cable is located near the PMM inlet valve.

It happens that the cause of error E4 is water in the PMM pan. In this situation, repairs will be more difficult. You will need to disassemble the machine to determine the source of the leak. It is better to entrust such work to a master.

How did the liquid get into the pan?

What to do when Kandy's dishwasher reveals a leak? First, wait until the machine pumps water out of the working chamber into the sewer. After this, you need to disconnect the equipment from the power supply, close the shut-off valve and begin searching for the cause of the malfunction. Let's tell you what the problem might be.

External leak. Sometimes error E4 appears due to accidental water entering the dishwasher tray. For example, when one of the family members spilled tea near the typewriter. Take a look to see if the pipes near the PMM are leaking. All this can lead to activation of the Aquastop system.
Filters clogged. In this case, the circulation of liquid inside the machine is disrupted. This leads to drainage problems and overfilling of the dishwasher. As a result, water gets into the pan. The float rises up and the leakage protection system is activated. The solution to the problem is to clean the filter unit and “dry” the PMM.

The Candy manufacturer recommends cleaning the dishwasher filter assembly at least once a week, and removing large debris after each use of the PMM.

Using the wrong dishwashing detergent. Some housewives pour regular gel into the dispenser, for example, Fairy. It is characterized by increased foaming, and this is unacceptable for Candy dishwashers.Soap bubbles seep through the PMM door and also get into the pan, resulting in error E. In this situation, you will have to immediately turn off the machine and leave it to dry for several days. The use of household chemicals for manual washing is fraught not only with triggering Aquastop, but also damage to the electronic module of the device.
Detergent dosage violation. Even when using special household chemicals for PMM, you can load too much powder into the machine, which will also lead to increased foaming. Foam will get into the pan, the equipment will display error E. The solution to the problem will be similar - the dishwasher must be left for 2-3 days to dry.
Adding waste liquid from the sewer. This is a fairly rare problem, but its possibility cannot be ruled out. This can only happen with dishwashers connected to a siphon. Waste water flows from the pipe into the machine, to which the latter responds with error E. The solution will be to clean the “elbow” and install a check valve that will prevent wastewater from flooding into the PMM.

To prevent waste liquid from pouring from the sewer into the dishwasher, you should position the drain hose according to all the rules - at the level of the sink, making a loop. You can also connect the corrugation not to the siphon, but directly to the pipe. Another option is to install an “elbow” with a check valve.

To drain the water from the dishwasher tray, simply tilt the appliance back. For some models, you will have to remove the side wall of the case and only then remove the liquid. As an option, open the PMM door and simply do not touch the equipment for 2-3 days, then the dishwasher will dry itself.

Where are leaks usually found?

The reasons are not always simple problems that can be easily fixed on your own.Sometimes you will need the help of a specialist. In what cases is it better to call a specialist?

Leak inside the PMM. Candy dishwashers often leak internal pipes, as well as circulation system paths. The specialist will carry out diagnostics, replace rubber gaskets, tighten clamps, and install new hoses. The cost of such work is low.
Damage to the pan seal in the working chamber. A typical problem with machines that have been in use for more than 5 years. The gasket wears out, cracks and begins to leak. The technician, using a repair kit, will fix the problem.
Violation of the tightness of the working chamber. This is a matter of corrosion. Such a breakdown is extremely rare, mainly on machines that have been in use for more than ten years. The stamping areas at the base of the hopper, near the glass, are rotting. The damage is minor, and can be temporarily sealed with a special sealant - this will extend the “life” of the dishwasher for several more months. In the future, the entire washing chamber will have to be replaced.
Damage to the salt flask or heat exchanger reservoir. There is always water in PMM, so if you leave the equipment in a cold room, the liquid will freeze, which will lead to rupture of plastic parts. The technician will find defects and replace components.
Damage to the leakage protection system sensor. Sometimes the device gets stuck and incorrectly reports a problem. In this case, it will be enough to change the Aquastop inlet hose. In this situation, you can only pay for diagnostics and perform the replacement yourself.

You cannot continue using a dishwasher that displays error E4. This risks not only flooding the room, but also short-circuiting the equipment. Therefore, be sure to fix the problem, reset the code, and only then use the machine.
