The error code E14 on the Siemens Dishwasher indicates an issue with the water supply, most probably with the water flow sensor of machine.
The water flow sensor regulates the flow of water in the machine. When the machine gets enough water, a signal is transmitted to the main unit, informing it that there is no need for more water.
So, in case of the failure of this component, the amount of water will not be normal in the machine. The malfunctioning of inlet valve and the main module can also lead to this error.
Fixing the Error Code E14
The first thing that you need to do in this case is to plug off the machine from the mains and then run it again after 10-15 minutes.
Also, tilt the device to its left side, at an angle of about 20 degrees, this will help in minimizing the excessive pressure. If this doesn’t help, proceed with analyzing the flow sensor.
Once you have located the flow sensor, you need to examine it with a multimeter.
Also, check the contacts surrounding the flow sensor. Clean the contacts. If the flow sensor is malfunctioning, consider replacing it.
