Can you post the E-Nr number of the appliance please?
It may be faintly etched across the top of the door.
E14 indicates a filling problem.
What exactly happens when you try to use the appliance?
Does the machine fill with water?
E14 is the error code for a fault in the flow meter.
The pump detects water in the machine while the flow meter hasn't registered any.
Unplug the appliance.
Take it out and take off the left side panel.
On the large plastic tank on the side you find in it a flow meter.
Disconnect the wiring to the reed switch and plug it back on again.
Do this several times.
Then, try the machine again.
Let me know what happens.
I will do what you have sugggested, however I won't be able to find the time to do what you suggested until tommorow afternoon at the earliest. Is that ok with you?
Just post when you can.
