Whirlpool appears to run through all cycles; you can see hot soapy water in the tub and water on dishes on top and bottom when you open door mid-cycle; water is hot; water drains appropriately; yet dishes do not seem to get clean, especially on top shelf. I know water and soap are getting there because frequently there is soap residue on top of cups. Saying that, it appears dishwasher is a sterilizer at best. Dishes have to be completely washed and all grease removed before put in the washer for them to come out that way after washing.
I did notice today that the cap with a seal on top of the lower arm is split and i am replacing this, but is that all i need to look at? I assume replacing that will make more water shoot up to the top shelf.
I am a novice, so any help you provide needs to be written at a very basic level …Thanks
