miele 646sci plus.

hi guys i think i know the answer to this but im after confirmation as its virtually impossible to get out and i only want to do it once.

symptoms are that the fill/drain error light comes on. first of all it can fill and drain no problem.

set a cycle even just a rinse and it will fill and begin spraying. all seems good. after a couple of minutes the error light comes on and the motor stops. all leds in display remain lit. there is a couple of seconds pause and then it sprays again for a few seconds. this is repeated.

my theory is a blocked or faulty turbidity sensor.

is there a test sequence that will confirm this.
thanks

Re: miele 646sci plus.

Likely a blocked impellor of the circulation pump motor, the appliance looks for a pressure switch mounted on the said motor to be activated, if it isn’t it goes into fault mode, starts & stops motor several times to try & clear any blocage.
