My Duracraft DD-TEC10E dehumidifier has come up with an E2 message that I cannot clear to make it work, any ideas?

DIY fix for Duracraft TEC10E E2 error, in case it's useful for others:
(When I tried to get a replacement temperature sensor via UK/Ireland support (kaz.com -> www.hot-europe.com) I was told that a replacement sensor was not available, nor was my unit serviceable).
Anyway, after a bit of messing with a variable resistor, I found that it would trigger E2 at a resistance of 560-580K, and also at resistance < ~1K (I stupidly destroyed the faulty temperature sensor trying to take it apart, without first checking what kind of resistance it presented, so I don't know whether mine broke OC or shorted).
Assuming an NTC thermistor, and a threshold of 0degC - the sensor is just to stop the dehumidifier cooling coil from icing up AFAIK - a 150K NTC thermistor with 'B'(25/100) value of 4400 should give a suitable replacement, with a 0degC resistance of 579K.
I wasn't able to find an exact such replacement, but I got a 150K/B~4000 from Maplin, put a 170K resistor in series, sheathed it up and installed it, and initial results look good - putting an ice-cube on the new sensor will trigger an E2 on the unit.
YMMV.
