No fill..no water..
Check the problem on the filling section...
The machine should fill first of all and after this to run in any of the cycles.
Can be..solenoid for fill.
the water line is close :)
the drain solenoid is broken and all the water is draining
Good luck

Common problem with these. Control panel (behind all the buttons on the door) has a thyristor in the middle of the PCB for switching the heater element ON/OFF.
After many screws and a bit of fiddling about, get access to back of PCB (print side) to find dry joints. Clean and re-make joints and all should be well.
Caution, this is a high voltage area. Disconnect from mains.
Please see photos.

Check that your supply faucet is open, Check if there is a screen in the supply line, these can become blocked due to scale deposits from the mains. If there is no screen check that the inlet solenoid valve has not got blocked. If none of the above help, check that there is power getting to the solenoid valve when the machine is supposed to be on the fill cycle. If no power is betting to the valve, the timer might ba faulty. (You can try hand filling the machine and see if it goes through a cycle, at least up to the rinse stage, this will tell you if the timer control is working).
If you feel that there is water not being pumped out, remove the bottom strainers and make sure that there is nothing obstructing the outlet pipe and the pump. If possible back flush through the outlet pipe and try draining the machine again before using it again.
