Product review (2 stars): the other one did solve the problem with our dishwasher and so I am pleased with it
There are 2 different products identified as  an "amerigap T52".  There is only a subtle difference between them, which I did not understand and which the information on the Amazon site did not adequately explain.  This device does not work with a dishwasher (unlike the other "amerigap T52").  Consequently I ordered the wrong version and had to go to the expense and trouble of returning it and getting the other one.  However, the other one did solve the problem with our dishwasher and so I am pleased with it.  It's the explanation, not the product, that is the problem.
