Hello Jess, my name is George..The problem with your tumble dryer is that the NTC on the heater circuit is either defective, or there is a problem with the wiring to it...Access the heater at the rear of the machine and check the wires going to the NTC. There part number should you need to replace it is #00600157 and it is available from Bosch at the following linkhttp://www.bosch-home.co.uk/store/product/SensorNTC/00600157Please remember to rate the assistance given by me today and kindly be patient whilst awaiting any responses from me as I'm not constantly available.
Hi Jess, did you test the wire the wires that are connected to it?..I did say:
either that or the heater could have a problem.. or, unlikely as it may seem, the part you have purchased is also defective
Notwithstanding these scenarios, the actual fault code is indicating a problem with the actual NTC
