Hello,

Welcome to FixYa.

This is a common complaint following a drain pump change out, particularly when one has an older Bosch and installing the new style/revised outlet pumps.

If you still have your old pump or if you recall observing it, that design usually only had 4 vanes on the impeller to pump the water.

Since then however, Bosch has re-designed their drain pumps to allow them to be "quieter" hence they now have either a 6 or 9 vane ( depending on model ) on the pump impeller, so yes they are much quieter but as a result pump less water in the time allowed.

example...

Small amount of water now - f12cc20.jpg

...So to answer your question it likely is normal and should be of little consequence. but if you`d like you can still get the other style, you just need to know what to ask for but is quite often "special order". Part # 184178.

NOTE - If you live in the Northwest region of the states ( Especially Washington ) often installation for dishwashers include what is know as a "Johnson Tee" air gaps in the wall.
**Johnson Tees were designed for older dishwashers with 1/2” drain
tubing and work better with stronger 4-vane drain pumps (# 184178) instead of
the current quieter 6-vane pumps (# 167082). In homes with Johnson Tees, use
only 4-vane drain pumps (# 184178).**

Hope that helps, let me know if I can assist you further and good luck.

these elctronic controls can become problems to troubleshoot sometimes. however the normal operation on this model when you power up is it will drainn first or try to drain any water left in bottom to make sure you have fresh water. then the door will lock prior to it filling with water... i would first try to look at drain pump and hose to drain and make sure no obstruction and that drain pumpp is working properly... if all looks good and your sure drain pump is ok then look at the door lock mechanism as it could have failed... repost with anymore questions ,but willing to bet the drain pump is the culprit...

Tip

Winterizing a Washing Machine


If you keep your washer in area where you need to winterize for the winter (unheated garage or unoccupied vacation home), the following steps may provide you with some helpful guidance in preparing before extreme temperatures occur and possibly leave you with damaged plumbing and/or a ruined appliance.<br /> <br /> <b><u>TOP LOADERS</u></b>:<br /> <br /> 1. Turn off the main water supply to both water taps.<br /> <br /> 2. Remove the fill hoses, drain them of all water and reinstall them - leave water supply turned OFF.<br /> <br /> 3. Add 1 gallon of Recreational Vehicle (RV) antifreeze (non-toxic) to an empty wash tub.<br /> <br /> 4. Select the DRAIN/SPIN function on the timer and allow the washer to run for one minute to drain the antifreeze from the wash tub, and any water remaining in the drain pump or drain lines. <br /> <br /> NOTE: Not all the antifreeze will drain. A small amount will remain in the drain pump and line (this is normal).<br /> <br /> 5. STOP or CANCEL the timer on the washer and UNPLUG.<br /> <br /> 6. Wipe down and dry the wash tub.<br /> <br /> 7. Clean the detergent dispenser and fabric softener dispenser and ensure they are dry.<br /> <br /> 8. Store washer, unplugged in an upright position.<br /> <br /> <br /> <b><u>FRONT LOADER</u></b>:<br /> <br /> 1. Turn off the main water supply to both water taps.<br /> <br /> 2. Remove the fill hoses, drain them of all water and reinstall them - leave water supply turned OFF.<br /> <br /> 3. Add 1 gallon of Recreational Vehicle (RV) antifreeze (non-toxic) to an empty wash tub.<br /> <br /> 4. Select the DRAIN/SPIN function on the timer and allow the washer to run for one minute to drain the antifreeze from the wash tub and any water remaining in the drain pump or drain lines. <br /> <br /> NOTE: Not all the antifreeze will drain. A small amount will remain in the drain pump and line (this is normal).<br /> <br /> 5. Press PAUSE/CANCEL twice to halt the cycle and UNPLUG the appliance.<br /> <br /> 6. Wipe down and dry the wash tub.<br /> <br /> 7. IMPORTANT: Check the perimeter of the door bellow (gray rubber seal) and make sure no small articles of clothing are left in the rubber folds. Clean this area thoroughly and dry. NOTE: Anything left behind will mildew over a period of time causing foul odors.<br /> <br /> 8. Clean the detergent dispenser drawer of any remaining water or fabric softener residue.<br /> <br /> 9. Store washer, unplugged in an upright position.<br /> <br /> <b><i><u>Secondary Method</u></i></b>: <br /> <br /> If you cannot find RV antifreeze (or prefer not to use it), another method of draining the washer is to remove the drain hose from the standpipe at the wall and pull a vacuum on the line with a wet/dry shop vac. This will pull any remaining water from the drain pump and lines. <br /> <br /> If a shop vac is not available, lowering the drain hose from the standpipe to the floor will allow it to drain using simple gravity. <u>IMPORTANT</u>: On a front loader, you may have to remove the drain line from the drain pump to drain the pump. Or, use the access cover (if equipped). Most front loader pumps are accessed by removing the lower panel directly below the door.<br /> <br /> <b><i><u>Taking the Washer out of Winter Storage</u></i></b>:<br /> <br /> To remove antifreeze from the washer following storage, run the appliance on a complete cycle with detergent and NO garments added.<br /> <br /> I hope you find this information helpful. If you have any questions, please let me know.<br /> <br /> <br />

I would like to know if you have water left behind in the area of the drain is that normal? Should this be completely drained away?


No, it's totally normal, The pump can't totally empty the washer and the hose because once it starts pumping air and water the air gives least resistance so the water remains in the hose. When the pump switches off gravity pulls a small amount of water back into the drain.

Your washer is 100% fine.

Glasses and dishes are coming out with white residue and clumps on them after full normal wash and dry cycle


Hello.. Firstly check thet the spray arms are clean. make sure there arent any jets blockd. Make sure the spray arms turn freely. Before closing the door on a cycle spin the arms to ensure no item is stopping the turning action.
make sure all of the water pumps out of the machine. There should be only a small amount of water under the filter after use. Any blockages should be cleared. Check where the drain connects under the sink for a partial blockage down the spiggot.

So if all this is Ok then ensure there is rinse aid in the dispenser. do not use tablets onlyrinse aid in the dispenser provided. Use a small amount of powder in the dispenser. Too much powder can over saturate the solution doing the wash and leave too much cloudy residue.

I assume the water being used is not too hard. It can look clear in a glass but be too hard. Especially artesian water.

You might try an acid descaler to return the machine to an internally clean condiditn. By the way always use a hort cycle. Economy cycles dont do yhe jop over a long period. You need to have a hot 70 degree cycle regularly.
Good luck

Not draining


Hi,
Draining problem is very common in Bosch washers. However, it is very easy to fix.

1) Remove the white circular plate, located on the bottom left. Push a small screwdriver or needle through it and simultaneously rotate the plate clockwise.
2) Open the drain valve. Rotate the circular black handle counterclockwise. Beware of residual water.
3) Clean it. Re-assemble in reverse order.

We own a Maytag washer - model number MAH4000AWW. When I turn the tub, I can hear what sounds like a siginifcant amount of water somehwere within the unit. The machine sat for several month while our house...


It is normal to have residual water in these washers. As long as the water does not appear in the spin basket (stainless steel tub), that is. If the water appears in the spin basket, you have a problem with either your pressure switch, or you water inlet valve not shutting off. The residual water, however, provides a necessary barrier to prevent sewer gases from entering the appliance from the drain line. However, if the washer has been sitting for a long time the water will become stagnant (as you have discovered). If you own a wet/dry shop vac, remove the drain line from the standpipe at the wall and pull a vacuum on the line. This will remove all residual water without the need to disassemble anything. Then, prior to washing any clothes, I would recommend running a load with no clothes with hot water and a small amount of bleach. This will kill any remaining bacteria. I would recommend repeating this procedure about once a month, or more often if you do not routinely use hot water.

If you have any questions, please let me know. I hope you find this information helpful.

Water does not drain from the bottom. I understand that a small amount is normal, however, this is not a small amount. Thanks for your help.


It worked for me .I have a danby countertop dishwasher.
I took off the metal top
I looked under on the left side to find the pump
I took both hoses off the pump and took off the little fan.
i took off the little metal bracket behing the little fan. and unscrewed the little pump to take it out.
the little metal piece that the fan was on wouldn't even move.So i sprayed it down with wd and it started moveing again then a screw fell out.so i found where it went(inside the motor which the fan and metal piece move) got the tweezers and replced it. oiled it some more and put it all back together. Perfect.

Won't drain


Remove the lower kick panel under the door and you should see the drain pump located directly under the wash tub. There is a screw off cap that can be removed to access the clean out trap. It is strongly recommended that you drain all residual water from the wash tub BEFORE you remove the drain pump cap, or you will have about a gallon of water to clean up. The residual water can easily be removed with the use of a wet/dry shop vac. Just remove the drain hose from the standpipe and pull a vacuum through the line with the shop vac. This will save you time later in clean up. If you do not have a shop vac, grab some old towels and place them under and around the drain pump. This will help in controlling the amount of water spill.

PS This residual water is normal in washing machines and should not be considered a problem unless the water is visible in the tub. Residual water generally sits between the outer tub and wash basket in the drain lines. This is truw with top loaders as well. Most front loaders will start a brief drain cycle at the beginning of the wash cycle to get rid of this residual standing water to prevent stagnant water from getting on your clothes. Just thought you might like to know...

I hope this helps you.
