Diagram of a craftsman power washer

The only filters on a pressure washer are: Where the hose hooks up to the pump there is sometimes a washer with a screen inside it. The syphon hose usually has a fine filter on the end that drops into the detergent. If this question is related to your other post see my answer there.

F21 error code is indicating that it is taking too long to drain water.

Your details indicate that you are using too much detergent or the wrong type of detergent and causing excessive suds. The drain pump can not pump suds out. The washer requires HE (High Efficiency) detergent formulated for front loading washers.

Cut back on the detergent and it will most likely operate correctly.

NOTES:
* After four (4) minutes the "Sd" error will be displayed, and then four (4) minutes later the "F21" error code will be displayed.
* Press STOP two (2) times to clear the display.

Possible Causes:
- Using too much High Efficiency (HE) detergent and causing too much suds.
- Using NON-HE detergent causing too much suds.
- Kink in drain hose
- Debris or foreign objects in drain pump filter.

The drain filter is located behind the lower access panel.

NOTE: Disconnect the power cord before removing the lower access panel and cleaning out the drain pump filter.

Remove the two screws (key#21) securing access panel. The filter cap (key#14) is removed by turning it counter clockwise. NOTE: Be sure that all the water has pump out before removing the cap. Have some large towels handy because there will be water coming out the filter/pump once you remove the cap. Check and clean the filter and remember to reduce the amount of detergent and the washer should perform as designed

Hi,

If detergent is left in the compartment:

? Be careful not to load items so close to the dispenser
that the cover will not open to release the detergent.
? The dispenser is not supposed to open when you
use the Rinse program.
? Your dishwasher detergent should be fresh and
stored tightly closed in a cool, dry place. Old or caked
detergent should be thrown away because it will not
dissolve properly and will leave a gritty residue on
the dishware.
? Wait until you are ready to start the dishwasher to
add the detergent.
? If you are using the Delay program, make sure the
dispenser is dry before adding the detergent.
? The detergent compartment only opens in the main
wash programs, not the Rinse program.


YOU MAY NEED TO CLEAN THE FILTERS MORE OFTEN
IF YOUR AREA HAS HARD WATER
This can cause low water pressure.
In hard water areas, it may be necessary to clean chemical buildup from the filters every 12 to 18 months. To do this, remove the coarse filter by squeezing the
tabs and lifting it out. Next, unscrew the fine filter and lift it and the main filter out. Wash all three filters gently in hot, soapy water and rinse them thoroughly.

Your spray arms may be clogging causing low pressure too.
Spray-arm jets and bearings may sometimes become clogged with hard water chemicals. To remove the spray arms, screw off the nut and take off the washer on top of the spray arm and lift off the arm. Wash the spray arms in warm, soapy water. Use a soft brush to clean the jets. Rinse thoroughly and replace.

Try cleaning the drain pump so it gives you more water pressure.On occasion something may get through the filters and into the drain pump. The drain pumps on ASKO dishwashers are designed to automatically reverse if anything should get caught in the propellers, thus ejecting the item back into the sump area or down the
drain. Should you need to remove an obstacle from the drain, first turn the power off then remove the filters . Next, lift out the small black insert
from the sump area. (You might want to remove any standing water first.) You can then look into the sump area for the item causing the obstruction. Should you
find something, simply scoop it out. Be sure to replace the black insert before you put the filters back in.

You could also try to clean the dishwasher with ' Dishwasher Magic '. This would work like charm :-

Thanks for using ' Fixya ' and have a nice day!!

If you live in a area with hard water, there may be a large buildup of hard water/soap scum in the bottom water reservoir where the pump, filter, and other working parts are. This is located inside the tub, not underneath. This scum/crystallized material can clog the water channels & filter so the water jets don't spray hard enough, as well as overwhelm the filter. Because phosphates were ordered removed from dishwasher detergents, hard water minerals can now react with the soap to create a heavy greasy-feeling scum. That scum can build up in the water lines, arms, bottom reservoir, and filter, providing an endless supply of goo to spray on your dishes. This can be fixed. You need to remove and clean out the spray arms, the filters, and especially the array of parts at the bottom of the tub. I've seen up to 1 cup of coagulated/crystallized scum in the bottom of dishwasher tubs (I know this may be beyond many homeowners, so if you aren't up to this first step, then just try the next/second step but do it 3 times with no dishes in the washer). Once you clean out the scum, then run the washer empty with a completely full detergent cup on the highest temperature setting, extra rinse. Before you start it add to the detergent cup 1 teaspoon of TSP(tri-sodium phosphate), a very powerful phosphate cleaner available at hardware stores. Your washer will now have all scum gone from the inner workings. From now on you must always fill both your detergent and pre-wash cups to the max and use a high temperature water setting, extra rinse. Chemically what you're trying to do is adding so much detergent that the scum-forming reaction is overwhelmed by the dispersant action of the detergent, and the extra heat helps this to be more effective. I am not a fan of vinegar in the wash cycle. Why? In some washers the vinegar fumes can reach the exposed contacts of the printed circuit board or touch pad, corrode them, and then your washer won't work at all, along with being very expensive to fix.

Did you add detergent to the dispenser?
For best results, add detergent to the detergent
compartment. Do not add detergent to the washer drum.

Did you sort properly?
Sort lint givers (towels, chenille) from lint takers (corduroy,
synthetics). Dye transfer can occur when mixing whites and
colors in a load. Sort dark clothes from whites and lights.

Did you overload the washer?
Do not overload the washer. The washer can be fully loaded,
but not tightly packed. The wash load must be balanced. Lint
can be trapped in the load if overloaded.

Check the following:
Was paper or tissue left in pockets?

Did you use enough HE detergent?
Follow manufacturer’s recommendations for the type of load
you are washing. For best performance, use only High
Efficiency detergent. Use enough HE detergent to remove soil
and hold it in suspension.

Do you have hard water?
Use more detergent for washing heavy soils in cold or hard
water.

Is your water colder than 60°F (15.6°C)?
Wash water colder than 60°F (15.6°C) may not completely
dissolve the detergent. Use hot or warm washes if safe for the
fabric load. Make sure your hot water system is adequate to
provide a hot water wash.

Have you run the Clean Washer Cycle lately?
To freshen your washer and to avoid odors, see “Cleaning
Your Washer.”

Are you using HE detergent?
Use of non-HE detergent can cause a film residue which can
result in odor.

Did you leave the door open after use?
This washer has a tight seal to avoid water leaks. To avoid
odors leave the door open to allow the washer to dry
between uses.

I had similiar problem, be sure the detergent hose isn't clogged. Mine was clogged where the clear detergent hose entered the pump. I cleared the clog and it worked perfectly

I had to have repairman out. He said it had a filter in front panel that needed to be cleaned. It was full of hard white stuff, like caliche dirt. He noticed I use Arm & Hammer Detergent and he said that was good, but don't use HE detergents because when they mix with city water, it causes an odor in washer. Thanks- Beth

Hi hope i can help!!
Try this empty the detergent tank then have your machine ready to work then half fill the tank with warm water and use the machine, this may take a few attempts so dont think its a 5 min fix! What happends is the detergent when left in the machine goes thick and gooy the warm water thins this and eventualy cleans it out but dont use boiling hot water this may damage the seals.before storing machine away do this method.
Hope this helps .Sean

no its a hard water problem cut the amount of detergent by 1/2 but no less than a teaspoon make sure your rinse aid dispenser is full and once a year do a winger rinse use air dry or energy saving option put two cups of vinegar in a dishwasher safe measuring cup on the bottom rack.run a complete washing cycle using the air dry option no detergent the vinegar will mix with the water.run the washer through a normal cycle with detergent after cleaning the washer with the vinegar rinse this can be done once a year
