Summary: Excellent product once fixed.
Drain must remove water , tube cannot allow water to back up.
Island install, drain must go 3ft above floor and 10 inches above drain as in diagram
Major issue is the float on the right side. This must be always clean otherwise the machine will not fill correctly and drain at the right moment. My float was full of greasey residue. Steam is great, , takes many plates and ! select power cycle with steam.
