Our dishwasher top shelf is not cleaning.
My husband, son and I (in order of time committed) have taken apart the machine, cleaned the filters, examined the impellers (they looked ok, so we did not replace) and replaced the macerator.
Machine is getting enough water and is filling on the bottom to the heat coil, but not getting any water on the top shelf.
There are no funny noises. There were before we cleaned and replaced the macerator, but now the machine is quiet (too quiet). The motor is running. My husband is reluctant to replace the pump assembly because that might not be problem. But we have taken it apart 3 times and cleaned it. He is inclined to think the macerator (which we replaced with new) is either not engaging properly or is defective. There was significant debris on the macerator screen last time we took it apart and cleaned it and it did not appear to be engaged properly. We thought we got it in properly this time with the help of a pair of chopsticks.
$187 (approx.) is a lot to spend on pump assembly if that's NOT the problem. The macerator is tricky to install, with that spring and all, maybe he's right and it's still not aligned and engaged with the pump? The macerator was able to be turned after we installed it but maybe something is wrong and it's slipped and disengaging?
He also thinks pump motors either work or don't (and usually make a lot of noise when they don't) and that there must be a clog somewhere in the system.
At this point, I'm ready to give up and join the Amish -- just wash the dishes by hand. With all this discussion, time and energy we could have just washed dishes a few dozen times at least.
If you can shed light on the situation perhaps we could avoid such a drastic measure and continue to live in the style to which we have become accustomed.
Thanks for your patience and looking forward to your advice.
