It will operate without a purification plate, as long as you are running in RCI mode or normal mode. If you normally run the purifier with some ozone output, then you will need a purification plate. Hope this helps you.

No, just rinse the RCI target with warm water. Allow it as well as the purification plate to dry completely before reinstalling into the purifier. You can speed up the drying process using a hair dryer at a low heat setting. Hope this helps you.

You might be able to fix them.
There a couple of things that can go wrong with these units, dirty plates, bad contacts, and bad reostat.

Dirty plates:

The ozone is generated by the purification plates. They should be cleaned once a month with a solution of one part amonia and one part tap water. Use a soft bristle brush like an old toothbrush and scrub the metal contacts on the plates with the amonia solution. Be sure to do both sides. Allow them to sit with the solution for 10 minutes, then rinse off with tap water and allow it to dry completely.

Bad Contacts:

There is a couple of metal strips that make contact with the purification plate. Check the contact strips and wires for corrosion. The metal strips can also be cleaned with the amonia solution as well.

Bad Reostat:

The reostat is the part that attaches to the control knob that sets the purification levels. Sometimes it can go bad. The easilest way to check them is to use a meter and verify that as the knob is turned that the resistance changes with the position of the knob.

It is normal for the purification plates to have contact with the metal contacts. The metal contacts provide the electrical power to operate the purification plates.

Yes, must be replaced with same gauge wire(same thickness), good luck.
