Bauknecht GSX beeps after switching on and interrupts the rinsing program.
The cause is the defective temperature sensor/NTC sensor.
The faulty sensor on my machine had over 200 kiloohm in cold condition. The new one about 60 kiloohm. By filling the machine with approx. 1 litre of water at a temperature of 50 to 60 degrees the value of the defective NTC sensor dropped and the machine ran without an error message.
But I didn't want to work with this trick permanently, because the machine measures the temperature wrong and I fear that it then constantly washes off with too high temperature. To avoid that, I changed the probe. I bought it on eBay as new for 29 Euro.
The spare part number for my machine is 481228268051.
This is also suitable for many other machines. Also for the brands
Ikea, Whirlpool, Ignis
