The main aim of this article is Repair, Reuse & Recyle.
As per the Bosch website this error code means the following:
“An E14 error code indicates a flow meter failure or an issue with water flowing into the dishwasher or the filling system.”
First of all, check the inlet water supply to the dishwasher. Make sure there is no issue with inlet. The various checks that you can do are, check the dishwasher inlet tap/valve, check the plastic filters within the dishwasher inlet pipe etc.
If the error persits despite everything, it is very likely the flow meter issue. Please note, the following article details fix for Bosch dishwasher models that have the flow meter as depicted in this article however the fix is equally applicable to dishwasher models that have different looking flow meter components. The challenge on your part is to identify what the flow meter looks like in your dishwasher. Perhaps, searching on internet for the identification should help.
It is time to open the dishwasher. The tools required are very basic, such as multi-bit screwdriver set and the replacement part for the flow meter.
The flow meter in this Bosch dishwasher model looks like the following. This part only costs roughly £15-£25 when purchased online.
In fact, the sensor boad only has one electrical component and that is the tube looking part which is a Reed Relay. Just search online for to understand the function of a Reed relay. A Reed relay is nothing but a switch which made of two reeds which makes and breaks a contact if a magnet is passed in front. Over a number of years making and breaking the contacts, such relay can malfunction as it is an electro-mechanical component.
Such a Reed relay costs only 50p to £1 pound when purchased online. So, if you posses necessary skills to desolder the Reed relay on the old sensor board and source the exact part and solder it back to the board in the same manner as it was previously mounted, then you can solve this issue at an extremely cheap cost.
Therefore, the first thing to do is to disconnect the dishwasher from the power supply. Drag the dishwasher out of its cabinet. Then, first open up the top panel and then its side panels like so:
Now, let us locate the flow meter. The flow meter is housed underneath the white flap as shown in the following image:
Next step is to carefully lift the plastic flap up so that the flow meter becomes visible:
Then disconnect the connector that connects the grey cable to this flow meter, like so:
Now, carefully lift the flow meter and replace it with a new part and reconnect the cable like so:
Now, slowly and carefully push the plastic flap back into its position, just so that we do not break the flap:
Now, try running a wash cycle, the dishwasher should no longer display the error and finish its cycle normally:
