Water spraying from nylon radial bearing and lower arm seal
My dishwasher is whirlpool quiet partner 2. Made it operate with the door open by depressing latch with coat hanger. Bottom spray arm is delivering water out all the jets (about 3”) but is not spinning. I’m seeing that water is also spraying out everywhere around the nylon radial bearing and from around the plastic arm seal underneath the arm. Would that indicate the nylon bearing and arm seal are worn down? I have taken all these parts out, cleaned the sump, chopper, filter and arm. Prior was only coming out of spray arm jets but still not spinning. Appears it has better water delivery now but is spraying out from under the bearing and arm seal

What is the model number of the dishwasher?
On second disassembly, noted the spring of chopper blade to be misshapen and spring seat in the plastic impeller shaft to be worn out, chunks missing. Ordered the impeller kit. Symptoms of the washer are lower arm does not rotate, it’s jets are only spraying 3” high though the separator and arm is completely clean. Water sprays out of separator screen very well. Water sprays out from under the upper nylon radial bearing of the lower arm and there’s no water. Coming from upper rack spray arm. With the upper rack removed, there is no water coming from it’s fitting. Prior to the dishwashers final breakdown (thermal fuse blew mid-cycle) the upper rack got clean but the lower rack did not because the arm would stop spinning though it was still spraying. Removed screws (they came from pots and pans, not the washer hardware) and broken glass from the chopper, cleaned separator that was 90% clogged with paper pulp, replaced the fuse with whirlpool genuine part. Now it currently operates this way. The washer is otherwise very clean of grime and scale because I use phosphated detergent in it like the formulas available in the 90s when the washer was new.
Not sure if you mean that it is still happening after installing a new impeller or that you're still waiting to do so.
If new part not installed see how it goes once installed.
If a new impeller was installed I'm wondering if the wash motor is OK i.e. providing enough water pressure to force the spray arms to rotate.
Just curious if there was a tech sheet in a plastic folder behind the kick plate (toe plate) in the dishwasher. Usually there is one there. If so it shows how to run the diagnostics which may help.
@jayeff Havent gotten new impeller kit yet. The nylon bushing and arm seal have arrived and yea, the old ones are noticeably thinned out. Couldn’t find that service sheet. I have another manual meant for users, it doesn’t get into repair/service other than to say call qualified technician.
If that debris, screws and glass bound up the chopper could that make the fuse blow? like motor was pulling more current due to being bound up? I’m also curious if the lower arm (metal) touching the heating element could have made fuse blow?
There is the slightest amount of radial play in pump motor shaft. It would prob be .02mm feeler gauge. Unknown if this is an allowable tolerance or indicates pump is on its way out.
