Product review (5 stars): Perfect fit, good replacement.
My dishwasher had begun to leave dirty deposits on the dishes that were stacked in the corners, looking like dried on dishwasher soap. Took the filter out of the back to discover this valve all full of dirt. Cleaned it out and found that the rubber seal had turned hard and sticky and was being drawn up into the hole it seals and getting stuck there against the spring. The valve just unscrewed, used an old toothbrush to clean the threads, screwed this one in and presto! The pump no longer circulates incorrectly and my dishes are all cleaning properly again. Did require a bit of disassembly of the inside of the dishwasher (7mm bolt heads in this case) so beware, there will likely be tools required and definitely crouching inside the dishwasher to fit this.
