Miele G692 SC Plus JRBOTHERMIC dishwasher Inlet solenoid voltage?

I tracked the problem down to a few burnt components on the circuit board. Certainly a micro switch that powered the inlet valve, and a capacitor next to it. The board itself was very expensive to replace (over $600). I tried replacing the components (had to borrow a switch from the end of the board that used to control the salt thing) and repair a few tracks. I now have it sending about 28 volts to the inlet solenoids, but no action. Question is, do the solenoids require 240 volts, and I hav'nt succeeded in repairing the board, or is the voltage right, and the problem likely to be faulty solenoids? I can't see any visible problem at the solenoids on the end of the hose.
