Hi, I'm Daniel and I'll be helping you today I've been repairing white goods for 20+ yrs. and currently work for a well-know manufacturer.
E14 and E04 error codes can usually show themselfs at the same time like this. As E14 is a dryer NTC faut and E04 is a wash NTC fault. The NTC is a temperture sensor.
You need to pull the washer out and remove the top and access the dryer NTC on the top and check the wires on there and test it with a multimeter. It should give a reading of about 20K ohms.
If the dryer NTC is fine then you need to acecss the wash NTC which is in the heater and do the same to this.
But if both NTC senors are fine and the wiring is as well then its possibley the control board at fault.
As to the leak whilte its pulled out remove the back and check it for signs of leaking there.
And as to the noise when you turn the drum. As you may have something stuck in there. As you can get bra wires in there which catch as the drum turns. If this is the case then you need to remove the heater and then you can fish it out from between the drums in there.
Once the washer is out and the panels are removed then you should be able to sort this out. But from the sounds of this all 3 faults are not related so sound all different from each other.
Check that out and see what you find and let me know.
