Causes of malfunction
Bosh dishwashers are equipped with self-diagnostics, which makes it easier for the user to find the place of breakage. When the machine gives an error E 14, decoding the value is simple - the flow sensor has failed. He is responsible for the amount of water in the tank and is installed instead of the pressure switch in the technique with a flow heater.
The reason may be not only in the sensor, but also in its wiring. If the connection is broken, the element does not receive signals from the control module.
Error code E14 PMM can show on the display in such cases:
- There is no pressure in the system( or, on the contrary, it is excessive).
- The intake valve is out of order.
- Electronic card burned out.

How to Troubleshoot

- remove the fastening screw.
Reinstall the new valve.
