Aprilaire 560

No water flowing onto the pad

There is an orifice regulating flow which may be clogged with minerals. Or inlet control not operating.

[Todd H.]

Possible causes:

Water supply off.

Solenoid not receiving electrical signal to open.

Solenoid bustimicated.

Outlet orifice clogged with mineral deposits.

Caveat: experience with another aprilaire unit, and I didn't look up your unit specifically.

unit specifically.

There is also a fine screen filter on the incoming side of the solenoid. But to get it out, you usually wind up trashing it, so you should have a spare. Arnold Service Co on the internet sells them as well as the orifice. I'd start by measuring the voltage on the solenoid, or listening for it to click.
