Black pieces of particle come out of the jets when they are turned on.

The problem you are experiencing is common to many jetted bathtubs.It is a result of dried bathing water in the tub. There are a couple of solutions to resolve this ongoing problem.

1. Use your tub more frequently as the water will not have time to fester in the pipes.
2. Use a cleaning solution made for cleaning the pipes on jetted bathtubs once every three months.

That's a nice unit! You need to clean out the jet openings with a very thin piece of wire and, while you are at it clean off the whole grill so that no particles get trapped near the jets.

#K4421 Re black specks coming from rim jets (only). Me too. Looks like bits of rotting rubber. Water in tank is clear-no specks there. I suspect the small hose from fill valve to top of flush piston may be breaking down, as it has gone rigid and I'm afraid to squeeze it lest it shatter. First thing I'll try is replacing that hose, if I can find one.
My daughter has same toilet but no "specks". With her toilet, it's the same small hose but the problem is it occasionally pops off at fill valve end. I can fix that with wire but when I find hose source, I'll buy two.

Hi

While putting dishes in the washer and obstructing the spray ams which causes food particles to stay on dishes. After loading dishwasher and pushing in baskets ,be sure the spray arm doesnt hit any of the dishes causing them to not clean properly. If that doesnt work or is definately not your problem try removing the spray arm and seeing if it has food inside of it. Some times they get food build up in them and need to be flushed out.

However the other causes for this problem are…

Not enough water entering dishwasher (check level after fill... Should be slightly below bottom wash arm)

Water filling but draining during wash cycle. Check toward end of wash cycle but before drain. See if water level is diminished from start of wash cycle.

New 'water saver' dishwashers are notorious for having smaller water jets, and thus easier to stop-up jets. Check the jets on all wash arms to be sure they are cleared of food particles.

Another way to check the wash arms is to manually position them at specific locations, momentarily run the dishwasher for a few seconds, then open the door to inspect the location of the wash arms. Do this three or four times to eliminate the possibility of coincidence.

If the wash arms do not move from the location that you put them, the most likely cause is food particles stopping up the water jets. These jets not only clean the dishes but also the water pressure they generate turn the arms inside the dishwasher to properly distribute water pressure on the dishes.

Sometimes you can dislodge and remove food particles stuck in one of the jets with a toothpick or other small probe. Others require that you remove the arm(s) and get a little more creative. I use compressed air to clear mine, but not everyone has access to compressed air, so use whatever you can to remove the food particles.

Simply dislodging them from the water ports is usually not effective... As soon as water pressure is applied, the particles return to the jets and stop them up again. The real fix in this instance is to completely remove the food particles from the arm if you can.

Let us know if you want to know something more else please accept the suggestion.

Are dishes also not coming clean? Most likely, there is not enough water chruning in the tub to rinse soap out of cup during wash cycle. Sufficient wash action will wash the soap out of the cup and dissolve it in the water within a few seconds of the cup opening.

Sounds like the hoses to the jets are the pump are breaking down and pieces coming off. Replace the bad hoze(s).
