Works great.  This part in the washing machine works on a siphoning principle to get the detergent into the washer (water is put in the top during the washing cycle which starts the siphoning action). My original part (after about 9 years of working correctly) would be full of water after the washing cycle was completed; I don't know why it stopped working (no visible sign of a problem) - but it did.  This replacement part fixed the problem.  Another feature of the replacement part was the fill level indication; my original part only had a "Max" level indication - this replacement had both a "Max" and "Normal" level indication so you can just pour detergent from the bottle directly into it (rather than needing to pour into the measuring cap and then into this dispenser to get the correct amount).
