Hi,
since a couple of days the detergent dispenser of my AEG (Typ: GHE423CA1; PCN: 91107602801) dishwasher does not work any more. To be more specific, the tab compartment does not open anymore during the washing process (opens when the front-door is opened, after the program ends).
I removed the detergent dispenser to have a closer look what may have failed. The first suspect is the linear-actuaror/thermalactuator [1, 2] shown in the picture below. The thermalactuator has the number 100331 40K T105 designed for 110/240 V 50/60 Hz and is manufactured by Eltek (like the whole detergent dispenser). For me it looks like the actuator should push against the lever when it is excitated. By moving the"white" lever in the lower left by hand, opens the tab compartment.
My question is, how to properly test the actuator as I never came across such a device. According to the datasheet it looks like it should be fine to just apply the nominal voltage (230 V_AC) for about/maximum 2 minutes (standard cycle with 2 min. ON – 5 min. OFF mentioned in section 6.7) and having a look if the piston moves.
Has anyone experince with these thermalactuators? Why are they used in such kind of application?

... the electrical resistance determined with a DMM is about 2200 Ohm.
