When I drain the water out and take a look, there is nothing there! Any ideas?

Possibly a restriction in the drain hose or the drain coupling under the sink perhaps?

Hope it’s not the pump as that sounds pricey. Author Posts Viewing 4 posts - 1 through 4 (of 4 total) You must be logged in to reply to this topic. Log In Username: Password: Keep me signed in Log In
