Burning faucet indicator on the dishwasher control panel Bosch signaling the operation of the leak protection system AquaStop or critical disturbance of water circulation within the circuit. This signal is often accompanied by error codes. E09, E15 or E24The sensors detected either the presence of water in the pallet, or the impossibility of its normal intake and drain. Ignoring this warning can cause the kitchen to flood or the circulating pump to fail, so the reaction should start immediately after the symbol appears.
In most cases, activating the tap symbol means that the electronics have blocked further water intake to avoid an emergency. The user can watch the machine humming while trying to start the pump, but the wash cycle does not begin, and on the display or LED panel the corresponding icon continues to flash or burn in red. The exact cause lies in mechanical damage to the hoses, clogging of the filters, a malfunction of the float valve or a software failure of the control module.
Decoding of the indication and error codes
Understanding exactly what a flashing or burning faucet means depends on the specific dishwasher series. Bosch and the accompanying symptoms. In modern models with a display HomeConnect or InfoLight The problem is often duplicated by an alphanumeric code, which greatly simplifies diagnosis. If the tap is constantly on fire, it is more likely to indicate a static error recorded in memory, whereas blinking indicates an ongoing process of water discharge or an attempt to pump.
Most problems are classified by error codes, which are issued by the self-diagnosis system. For example, a mistake E15 indicates that the water got into the lower pallet of the body, activating the emergency float. Code. E24 He's talking about a plum problem, E09 - a malfunction of the heating system, which can also block the water supply. The most dangerous situation is when the crane is burning and the pump is buzzing at the same time.This indicates the operation of the emergency drain system.
- 💧 E15 - AquaStop system activation, water in the tray of the car.
- 🚿 E24 - A malfunction of the drain pump or a blockage in the sewer hose.
- 🔥 E09 A problem with a TEN or temperature sensor blocking the cycle.
- 🔄 E22 - Clogging of rough filters, preventing circulation.
It is important to distinguish between situations where the faucet burns after the program is completed and when an error occurs in the middle of the cycle. In the first case, it may be a residual signal about the need to clean the filters, in the second - an emergency stop. If the display displays the code F or EIt is necessary to fix it before the power reset, as this is the key to understanding the nature of the malfunction.
Mechanical causes: hoses and connections
The first stage of diagnosis should always be to check external communications, as they are subject to the greatest wear. Water supply hose connecting the water supply and dishwasher BoschIt is under constant pressure, which over time leads to microcracks or weakening of the clamps. Even a slight dip in the connection to the housing can activate the leak sensor located at the very bottom of the device.
Particular attention should be paid to the block. AquaStopIt is located at the end of the filler hose by the water pipe. Inside this thickened plastic block is an electromagnetic coil and a mechanical valve. If the hose is visible swelling, or the block itself has cracks, the system perceives this as a risk of rupture and blocks the water, signaling this with a burning crane. Replacing this hose is the only safe solution.
⚠️ Attention: Before inspecting any hoses and connections, be sure to close the water supply tap and disconnect the dishwasher from the power grid. Working with electricity and water is both deadly.
Internal hoses connecting the pump, heat exchanger and sprinklers can also cause the problem. If there was a water blow or pressure surge in the car, thin corrugated tubes inside the body could jump off the pipes. Water is poured directly onto the electronic components and bottom, causing an instantaneous defense response. To check these elements will require partial disassembly of the body.
Problems with the filter and drain system
Filter clogging is the most common and easily eliminated reason that dishwasher Bosch Can't see the water or can't drain it, giving a tap error. The filtration system consists of a flat mesh filter and a cylindrical element with a small cell. When they are clogged with food residues, fat and scale, the water stops circulating, the flow sensor detects the lack of fluid movement and blocks the program.
The pump (pump) also plays a critical role. If the impeller pump is blocked by a glass fragment, a lemon bone or a coin, the motor buzzes, but the water does not pump. In some models Bosch During prolonged operation in this mode, thermal protection is triggered, and the system produces an error indicated by a burning crane. Cleaning the pump snail often solves the problem without calling the master.
The maintenance process of the filter system requires care so as not to damage the seals. A tightly closed filter after washing will lead to the fact that large particles of food get into the drain hose and cause a more serious clog in the sewer pipe or siphon. Regular prevention is the key to long-term work of the technique.
Diagnostics of the AquaStop system and pallet
System system AquaStop dishwasher Bosch It is a double protection: an external hose in the hose and an internal pallet with a float. If the water still penetrates into the body (for example, due to a burst pipe or overflow), it drains to the bottom, where the foam float is located. As he rises, he closes the contacts, and the machine goes into emergency mode, starting to pump water endlessly with a drainage pump.
Visually, it manifests itself as follows: the car hums, even if it is turned off (while there is current), and the crane indicator burns. At this point, the electronics block the bay of new water. To reset this error, it is not enough to simply turn off the device from the socket - you need to eliminate the cause of water entering the pallet. Often this requires removing the side walls of the body to dry and search for leakage.
| Symptoms. | Probable cause | Method of decision |
|---|---|---|
| Hooding without stopping | Water in the pallet, drainage working | Drying, leak detection |
| The faucet blinks, no water. | No pressure in the plumbing. | Checking the tap, pressure. |
| E24 error | Flush or pump clog | Cleaning filters, hoses. |
| Crane + drop | Failure of the AquaStop valve | Replacement of hose with block |
If after drying the pallet and collecting water, the error disappears, but appears again after several sinks, then there is a chronic micro-leak somewhere. This can be a cracked hatch cuff, leaky pump connection or corrosion of the tank. In such cases, thorough defects of all nodes are required.
Failures of the circulating pump and sensors
The circulation pump is the “heart” of the dishwasher BoschIt provides the movement of water under pressure through sprinklers. If his porch is worn out and the shaft is lufty, the pressure in the system drops. A flow sensor installed at the pump outlet detects an insufficient volume of fluid passing and sends a signal to the control module to terminate the program. The panel lights up a tap, indicating a water supply problem inside the circuit.
Also often fail the sensors of water level or pressure. They may “lie” by telling the module that the tank is full when it is empty, or vice versa. As a result, the machine either pours water over the edge (causing the AquaStop to actuate) or does not collect it at all. Replacing these components requires disassembling the bottom of the machine and having a multimeter to check the resistances.
⚠️ Attention: Do not attempt to repair the control module or sensors without electronics skills. Incorrect soldering or replacement of parts can lead to short circuit and fire.
In some cases, the problem lies in the oxidation of contacts on the connectors of the pump or sensors. The moisture and aggressive chemistry of detergents do their job. Cleaning contacts and treating them with special lubricant for electrical wiring (for example, Kontakt Chemie) can restore operation of the unit without costly replacement.
Software reset and system reboot
Sometimes a burning crane is the result of a software “hang” of the control module, especially if voltage surges were observed in the network. In this case, the machine is physically healthy, but the logic of the work is broken. The first step should always be a complete reset. For most models Bosch This is done by holding the Start button for a long time (usually 3-5 seconds) or by a combination of buttons specified in the instruction (e.g., Program Selection + Special Features).
If soft reset does not help, a "hard" reset is required. To do this, the car is disconnected from the power grid (pulled out the plug) for at least 15-20 minutes. This time is necessary in order to discharge the capacitors on the control board and erase temporary errors from the RAM. After turning on, try running a short program.
In models with an intelligent system HomeConnect You can try updating the firmware through the application on your smartphone if the machine is connected to Wi-Fi. Manufacturers often release patches that correct false sensor alerts and logic errors that can cause a faucet indication without a real leak.
When a Master's Challenge is Necessary
There are a number of situations when self-repair becomes inexpedient or too risky. If the diagnosis showed that water flows from under the tank (corrosion or cracked plastic), restore tightness at home is almost impossible. Replacing a tank is often not economically feasible, as the cost of spare parts and work is up to 80% of the price of a new machine.
It is also worth contacting professionals if the electronic control module is defective. Burned simistors operating the pump or valve require skilled soldering and tuning. Attempting to replace the module entirely on your own can lead to incompatibility of firmware versions, and the machine still will not work.
If you do not have the skills to work with a multimeter, do not know how to disassemble the technique or do not have a diagnostic tool, it is better not to take risks. A professional wizard will conduct a diagnosis in 15 minutes and tell you exactly whether it is worth repairing a particular node or it is easier to replace the device.
Why is the faucet burning, but water is being dialed into the car?
This indicates that the drain or water level sensor does not see that the water has gone after the previous cycle, or the AquaStop unit signaled a potential leak, but the electromagnetic valve has not yet completely shut off the supply. It is also possible to stick the pressure relief valve.
Can I use the dishwasher if the faucet is flashing?
It's not recommended. Emergency operation can lead to flooding of neighbors from below, short circuit and final failure of the electronics. Use the Stop mode and call the master.
What does the E15 error code mean on Bosch?
The E15 code indicates that the leak protection system has been activated. The water got into the bottom pallet of the body (bath), and the float activated an emergency drain. The machine needs to be turned off, find and eliminate the leak, dry the pallet.
How to Reset a Crane Error Without Shutting Down the Network?
Try pressing and holding the Start/Reload button for 3 seconds. On some models, it helps to simultaneously press the buttons "Washing" and "Drying". If it doesn’t work, it’s only a full shutdown for 20 minutes.
