Miele Diswasher?

Hi i have a Miele G 1270 SCVI and i am getting a FO1 fault. i ahve googled it and it seems that the causes and remedy could be the following: Cause:
NTC temperature sensor R30 or its connection leads short-circuited. would you know how to acess the temperature sensor since i would like to change or test it thanks?

Remedy:

1. Check the temperature sensor and its leads for continuity. At 68°F (20°C), the temperature sensor resistance should be approximately 14.9kΩ (± 750Ω); at 77°F (25°C), approximately 12kΩ (± 600Ω) (guide figures only).

2. Check the plug connections.

3. Replace the temperature sensor, if necessary.

would you know how to acess the temperature sensor since i would like to change or test it thanks
