The short on the door leads will almost certainly have blown the PCB tracks at least I would think.

You would expect to see obvious signs of damage though 😕

Service Programmme 4- Thermistor Test.

To select Service programmes, press the programme select button and the half load buttons simultaneously then switch on.
The display will scroll through the various test programme numbers. Press start when the required number (4) is displayed.

This fills the machine and heats the water to 66°C. The measured water temp is displayed allowing the thermistor and temp measurements to be checked.
STEP………….DISPLAY………… ACTION
1-5 …………..water temp……….Fill 3 times
6……………………………………..Circulate and heat to 66°
7……………………………………..Circulate for 24 sec.
8……………………………………..Circulate and drain for 16 sec.
9……………………………………..End.

If the temp display does not rise on the display then the thermistor could be faulty or the heater is not working, but as Dave said, it could have damaged the PCB.

If you want the other test programmes let me know, the only others that are useful for servicing are the No: 2 Wash test & the No:3 Dry test. The dry test may be helpful as it should energise the heater for 16 seconds without water.
