Abstract
An automatic washer having an improved recirculation system wherein wash liquid is collected in a sump and recirculated onto the clothes load in a first recirculation loop and wash liquid is recirculated from a mixing tank through conduits and a pump back to the mixing tank to effect thorough mixing of the wash liquid. The mixing tank can be selectively connected to the first recirculation loop to direct selected amounts of wash fluid into the wash load, and a sensor is provided to sense the amount of wash fluid in the sump to assure that a sufficient amount of wash fluid is being recirculated into the clothes load.
