Small Particles Sand & White color particles from dispersion screen group head & in water
Small white & sand ( or slightly salmon or pink) color particles are dispensed in the water from the group head & dispersion screen when making coffee & or dispensing water for tea. I have ran water through this the machine so many times cleaned the screen etc., A smaller amount of the particles are dark. The particles are very fine & small in size. What is this? What is the problem?

I had this happen about 6 months ago. It was the heating element. I had to have it replace - about $225. Ugh. But it works great now. Good luck. If you have an espresso repair shop you can take it to, they can hook it up to an electrical tester and let you know if it the element.

The cloudiness could be suspended particles or algae. Use an algae k i l l er as recommended, then a flocculant (water clarifier) as recommended, then vacuum the pool bottom and run the filter overnight.
After that check the ph, alkali level, chlorine level, and adjust as needed. That should do it.
Considering you don't eat sand and dirt, I can only assume that the source of this contamination is from your water supply. Installation of a filter, either on the dishwasher supply line or preferably, the entire home, would solve this issue.
This is not an uncommon situation for sand filters(persistent or slow to clear cloudiness). Mostly, these days , pumps are oversized for filter flow rates resulting in water being ramrodded through sand bed. The first thing to do is balance the water. If chlorine not present, double the suggested dosage. We are also assuming that the m.port valve has not been disassembled. the best sand to use is a #20 or #2 white quartzite. If problems persist , then consider filter aiding media to help the sand bed trap finer particles.
The Hayward Pro Series Sand Filter uses an O-Ring on the stand pipe to separate water returning to the pool, after being filtered, from water coming into the filter from the pool. If this O-Ring is broken, missing or sufficiently worn, small particles of dirt and sand can by-pass the sand filter and return to the pool without being properly filtered by the sand filter.
This can be especially evident just after backwash and rinsing of the sand filter bed. During this time water flows up through the sand bed, opposite the direction in normal operation. This forces the top-most material of the sand bed to dislodge and wash out of the filter to waste. It can also force fine particles to enter through a faulty O-Ring into the pool return stand pipe. Then, when returning the filter system to normal operating mode, those fine particles enter the pool through the water return piping and collect on the bottom of the pool -- mostly small sand particles but potentially filtered debris particles that were captured on top of the sand bed.
To avoid this problem it's wise to replace this O-Ring every few years. And make sure to follow the manufacturer's recommendations regarding the amount of sand to fill when replacing sand. It's important to keep the top of the sand bed at the correct level to insure proper filtering and minimize stray particles coming back into the return water.
I'm guessing that these particles are white or almost white. If so, it is just a build up of chalk from hard water. You will probably find that they just brush off the clothing with your hand. Just buy yourself a proprietary steam iron descaler and follow the instructions, all should be well
dead algae is made up of microscopic particles. Most sand filters have trouble filtering out particles that small. I would recommend using a flocculent that will force the particles to settle to the bottom, you can then set the multiport valve to the "waste" setting and vacuum as much of the debris as possible. You can use an additive like fiberclear to help the filter clear the water up quicker.
try using a clarifier that you add into the skimmer such as Clearex 500. The flocculent only makes particles drop to the pool floor, a liquid clarifier actually coates the sand and will filter smaller particles. Also, check the o-rings on the backwash valve. If the o-ring(s) are damaged it may be letting some water bypass the filter.
You may be getting sand in from the supply lines. Fill a clear glass container from the sink a few times and look at the bottom for sand particles. You may be getting sand from a pool filter? Remove the filter from the faucet head (it should unscrew) and look for sand particles in it. You may not be getting them in the kitchen sink if the dishwater inlets are below the sink as the particles may be sinking to the bottom of the pipes. You may need to put a filter in the dishwasher inlet. Try filling the dishwasher by hand with bottled water once and then see if the sand is still there. If so, it probably comes in through the water supply.
