The detergent compartment door on daughter's machine doesn't open during the wash cycle. It was replaced by son-in-law (no technical background) with a unit he bought on-line and says there was no electrical connection.

How does this door operate?

What else could cause to fail to open on schedule?

I am a qualified engineer

Thanks
