indesit iwde12?

I have a faule with my Indesit Washer/Dryer. I need to replace the NTC but cannot find the part anywhere online.

Indesit list the correct part as C00083915; however, this does not fit in the heat box because the distance between the round metal flange on the sensor and the plastic flange is only about 6mm and needs to be 10mm.

The part currently fitted is
ELTH 27900051
162 000 461
15-08

I can't find this anywhere.

Please help me find my spare part.
