You might have come across the E14 error code if you own a Bosch dishwasher. It can be annoying to encounter this error, particularly if you’re unsure of its meaning or how to resolve it. Fortunately, technical knowledge is not necessary to comprehend this problem. With a little help, you can pinpoint the issue and take action to fix it.
The E14 error code usually indicates problems with the flow of water in your Bosch dishwasher. This code indicates that there is a problem with the machine’s ability to measure or control the amount of water entering or leaving the system. Numerous things, such as obstructions, malfunctioning sensors, or even issues with the water supply, could be the cause of this.
Although running into an error can be annoying, there is good news: a lot of E14 problems can be solved on their own without expert assistance. There are a few things you can do to get your dishwasher operating again, like clearing out a clogged filter, looking for kinks in the hose, or restarting the unit.
| Problem | Solution |
| Water supply issue | Check that the water inlet valve is open and the hose is not kinked. |
| Blocked filter | Clean the dishwasher"s water filter to ensure water can flow freely. |
| Faulty water inlet valve | If the valve is malfunctioning, it may need to be replaced by a professional. |

Probable cause of the malfunction
Bosch dishwashers made today come with an intelligent self-diagnostic system. In the event of a malfunction, the PMM logs the issue right away and alerts the user. Dishwasher error E14 alerts users to a water flow sensor malfunction. This element is installed on devices that have a flow-through heating element and functions as a pressure switch.
Additionally, a break in the circuit known as the "flow sensor – control module" could be the root of the error. As a result, you will need to examine the wiring and connection integrity. An additional error code might show:
- lack of pressure in the system (or, conversely, its excess);
- breakdown of the intake valve;
- damage to the control board.
You must inspect the water flow sensor, its supply wiring, the intake valve, and the electronic control module if the error code is E14.
A malfunctioning flow sensor is the reason for this error code in 90% of the cases. As a result, the Bosch dishwasher’s flow meter is checked first. We will instruct you on how to run diagnostics and replace the element if needed.
Checking and replacing the flow sensor
Flow meters are installed in the majority of contemporary Bosch dishwashers either in place of or in addition to the standard pressure switch. The flow sensor’s functions include recording the volume of water collected and figuring out the pressure at which the liquid enters the device. The "brain" may also produce an error E14 if the pressure is too high or too low.
The flow meter is a plastic component that contains the following:
- a propeller;
- a magnet;
- a reed switch (this is a glass flask with contacts hidden inside).
The flow meter operates on a very basic principle. The magnet is brought to the reed switch when water flows through the element and the propeller starts to rotate. The control module detects the amount of water poured into the machine and logs its volume because of the pulse closure.
The dishwasher is shielded from water overflow by the flow meter.
It is not required to take out the dishwasher’s flow sensor in order to perform diagnostics. De-energizing the device, cutting its connection to the internet, and taking out the case’s side wall suffice. The flow meter is a fairly large plastic component that is easily located and connected to the inlet valve via a pipe.
With a multimeter, you can check the flow sensor. The tester needs to be put in dialing mode before its probes are placed on the component’s contacts. The measuring tool ought to show an infinity sign in this situation.
The magnet must then be brought up to the flow meter. The multimeter screen should then display the readings. Here, the sensor is operating as intended. We can determine that the component is defective if the tester continues to show an infinite symbol.
You will need to replace the sensor in order to reset the error. A new flow meter can be ordered online or purchased from a specialty retailer. Consider the Bosch dishwasher’s model and serial number when selecting parts.
A functional flow meter can occasionally record water pressure that is either too strong or too weak. When this occurs, the dishwasher is stopped by the "brain" for safety purposes, and an error code appears on the screen. It is important to confirm that the water supply system’s pressure is normal as a result.
When a Bosch dishwasher displays error E14, it typically indicates a water flow issue, which is frequently brought on by a blocked inlet valve, clogged filter, or broken flow meter. You can try cleaning the filter, inspecting the water supply hose for kinks, and making sure the inlet valve is operating correctly to resolve this problem. Should these measures prove ineffective, it may be imperative to seek advice from a technician, as there may be a more intricate internal issue requiring expert handling.
Solving the problem with the valve
Occasionally, the system’s lack of water supply could be the cause of the issue rather than the flow sensor. This could be caused by a broken inlet valve, a clogged mesh filter, or a pinched inlet hose. You must examine every component.
Examining the Bosch dishwasher’s inlet hose is the simplest method. Verify that nothing foreign has pinched or kinked it. Check it for obstructions as well.
Check the mesh filter next. It is situated where the inlet hose is connected, at the dishwasher’s entrance. The mesh stops allowing water through when it gets clogged with debris and covered in scale and limescale. Reassemble the element after cleaning it.
Lastly, a check of the inlet valve is performed. Its diagnostics require a specialized tool, a multimeter. You’ll need to partially disassemble the Bosch dishwasher’s body in order to reach the element, so get your screwdriver ready.
Next steps, what should I do? The following will be the instructions:
- de-energize the dishwasher;
- turn off the water supply to the machine;
- disconnect the appliance from utilities;
- pull out the dishwasher to a place where it will be convenient to work with it;
- remove the right side panel of the dishwasher body by unscrewing the bolts that secure it;
- find the electromagnetic valve.
The Bosch dishwasher’s inlet valve is situated at the bottom.
A multimeter is used to diagnose the element. The part’s contacts must be touched by the tester probes. 500–1500 Ohms should be the resistance of a functional inlet valve.
We can discuss a broken coil if the multimeter display’s arrow remains stationary. The electromagnetic valve needs to be replaced because it cannot be fixed. Parts are bought for a particular model of Bosch dishwasher. Purchasing original replacement parts rather than analogs is advised.
After taking a picture of the wiring diagram for the valve, take out the malfunctioning element. After that, secure the new component in place and attach the pipes and wires to it. After that, replace the dishwasher’s wall and do a test wash. You can reset the error if the electromagnetic valve malfunctioned and caused the issue.
Although dealing with an E14 error on your Bosch dishwasher can be annoying, you can resolve the problem more quickly if you know what causes it. This error is usually connected to issues with water flow, which frequently involve the flow meter or the water inlet valve. It is imperative to inspect for obstructions, kinks in hoses, or malfunctioning parts that may be impeding the flow of water.
Try basic troubleshooting techniques first, such as cleaning and inspecting the inlet valve and looking for any obvious obstructions, before contacting a technician. You could also try to reset the dishwasher to fix any short-term issues. If the problem continues, though, a professional repair job might be necessary, particularly if the flow meter or other internal components need to be changed.
Maintaining your dishwasher properly can help stop problems like E14 from happening in the first place. Important procedures are to check hoses, clean filters on a regular basis, and make sure water flows properly. You can prolong the lifespan of your dishwasher and save money on repairs by taking care of small problems early on.
