Randy B. September 04, 2012 for Model Number shu43c02uc/14 I ordered a circulation pump repair kit - my question is on how to remove the existing circulation pump. I pulled the unit and located the pump. It appears that you push down and twist off or do you have to remove the impeller nut on the inside of the unit? I ordered the repair kit because when I started the cycle the unit would fill bottom basin and then I heard a groaning sound as the unit was trying to circulate the water. I was told by a local technician that it was a bad bearing on the impeller causing it to rub the outside casing. I'm able to move the circulation motor blades freely so I'm really wondering on the current diagnosis. Could it be the capacitor?
1 Answer Hi Randy. You release the latch tab on the pump hsg. as you twist and pull out the circulation pump. Use a shop vac to pick up the water and also clean the top of the inside of the pump/sump assy. While you have the motor off you can check the motor windings to see if they are all the same tolerance in ohms. It reads 10 ohms on the Wht/Rd wire and the white wire. It is rare that a capacitor is bad. Usually a groaning sound is from debris dragging against the impeller, broken pieces or a dragging armature in the motor. Make sure the motor spins freely when you have it apart. Thank You. Read More...
Alexander August 21, 2012 for Model Number shu3326uc/uc12 My Bosch will fill with water, but makes a loud noise the whole time, it kind of sounds like a can opener. There is no water pressure to the top arm, and the side hose that is supposed to send water out doesn't get any either. It runs the whole wash, but soap sits at bottom, and dish only get wet from steam. Is this the circulatory pump? If so, how does the repair kit work? Or is it an easier/cheaper fix? Thanks!
1 Answer Hello Alexander, You need to remove the bottom rack and the filter assemblies. Down inside the top of the pump assembly is a plastic cover held in place by a single torx head screw. I don't remember the size exactly from memory, but i believe it's a T-10 or T-15. Remove this cover with a pair of needle nosed pliers. It will pull straight out once the screw is removed. Now use a wet-vac to clean it out. If you listen closely when doing this, if a foreign item is in there, you can hear it go in the wet-vac.Once all of the water and debris is removed, use a flashlight and inspect the impeller. It should sit up square on the motor shaft. I always spin it with my finger. If you feel the magnetic field from the motor windings, the impeller is fine. If it spins freely and flops around you will have to replace the circulation pump motor. Read More...
Jim June 04, 2012 for Model Number SHU 8816 UC/12 I purchased and installed the BOSCH Circulation Pump Repair Kit (Part Number: AP2802376)for my dishwasher, and tested afterwards for runability. discovered leaks in gaskets to pump housing? (I think) causing water to fill in lower plastic tub. water filled disherwasher properly and spray wand appeared to function normally on first couple of tries. on last try to discver leak, disherwasher tub fills only partial and now pump mmotor does not operate spray wand. any ideas?
1 Answer Jim, Low water levels do affect the overall operation of the wash arms, so you need to check to see if there is and issue in the water valve 00425458 and plumbing water supply, and the water level switch 00263185. As for the leak, if the dishwasher sat for an extended period of time, the pump gasket 00263102 and other seals could have dried out and started to leak, or you may want to re check your previous work, Something may have gotten out of alignment or twisted ? Good Luck and Thanks Read More...
Carol M. April 20, 2012 for Model Number SHU991/5UC UC11 My dishwasher made an unusual noise and the drain motor operates with the door open. The normal control buttons do not seem to have any effect on the operation. Can you help us diagnose the problem? I noticed some water under the assembly. Is the pump assembly or seal bad? Thank you.
1 Answer Hello Carol, The Bosch dishwasher has a moisture sensor, (flood sensor), in the bottom assembly that will shut off the units' ability to do anything but drain out. The drain pump will run as long as the moisture is sensed and nothing else will work on the unit until the moisture under there is dried up. Normally what I see in this case is a bad water inlet valve 00425458. Occasionally, there will be a leak around a hose or seal but this is a situation where a technician has to "clamshell" the unit to gain enough access to locate the leak. Since the water inlet valve is the most common failure, I would change it before calling anyone for the more extensive repair. Also, while the old water valve is out, before you install the new one, I use this opening with a towel or paper towels to dry up the water that is in the base already. Doing so will enable the unit to operate again. You can, if you desire, leave the water valve off for a day or so with a fan blowing into the base to evaporate the moisture. This takes a while if there is water puddled in there so if this is the method you want to use, wick the majority out with the corner of a towel then use the air flow method to dry out the remaining moisture.

Mike L January 11, 2012 for Model Number SHY56A05UC14 My unit basin fills with water and pours out on the floor from the bottom door seal. It does not appear to be draining. I took out the filter assembly at the bottom of the tub and found shattered glass on the inside parts of the screen against the drain ports. Would this cause the drain pump to fail? Is this the sign of a bad drain pump?
1 Answer Mike, The drain pump would be a good place to start 00167082, If you had glass in the circulation pump and drain holes, you most likely have glass in the drain impeller, and a damaged drain pump, and/or clogs in the drain hose system. Thanks and Good Luck Read More...
Jan October 15, 2011 for Model Number SHY56A05UC Thanks for answering my previous Question. Ready to buy impeller kit: 2 quick Q's: 1) I have motor out, the green impeller is separate from the whitish ceramic disc....does that mean it's the problem (i.e. should it be "one piece'). 2) How do I get the ceramic disc off the motor center axle / core? Thanks
1 Answer Hi Jan. No, They should both be separate pieces. Place a 1x1' piece of wood on top of the motor. Use a screwdriver to pry under the disc and against the wood to lift off the shaft. Impellor kit # 00167085. Thank You. Read More...
Jan October 12, 2011 for Model Number SHY56A05UC Water comes thru spray arm (mainly the bottom, very little thru top) but not enough force to spin them. Pump also sounds noisy. Do I need a new "recirculation" pump or just an impeller kit? Thanks
1 Answer Hi Jan. Yes, you will need a recirculation pump rebuild kit. Part # is 00167085. Make sure the wash arms jet holes are unplugged with a pick tool. Make sure the drain hose is not clogged at the sink end and the sink also. Thank you. Read More...
Kraig August 14, 2011 for Model Number shu5312uc/u06 My dishwasher fills with water and drains at the end of the cycle, but is not spraying water. It is not making any unusual sounds. Would you think this circulation pump repair kit is what I need? Does it come with instructions? thanks.
1 Answer Hi Kraig. Is your wash arms jets plugged? Flush them out under the sink, dislodging with a pick tool. Is the filter clean? Remove all from the top of the motor and clean filter. The circulation pump impellor may have stripped on the shaft. This part # is 00167085. Thank you. Read More...
Andrew V June 17, 2011 for Model Number shx43c05uc My girlfriends parents well pump went out while the dishwasher was running. When they go to use it now, it will not fill water. I assume that the water impeller was destroyed. You can here the motor hum as if it is running normally. I have yet to work on it. I am trying to get a ball park figure.
1 Answer Hello Andrew, the dishwashers depends on the water valve 00425458 to fill with water. You're water valve might be defective and need replacement. Thanks! Read More...
Larry May 04, 2011 for Model Number SHX46B05UC/21 I searched the model number for my dishwasher which is SHX46B05UC/21 AND GET THE MODEL (/14), are they interchangeable? My unit does not have good pressure to the top rack. Near as I can tell, the pump is working, but may have a weak/broken impeller. If the bottom is cleaning, and the top isn't, would a rebuild kit likely be needed? If so, what part number do I need for my model?
1 Answer Hello Larry. Make sure the water level is getting high enough for the system to work properly. If it is low, the upper spray arm will not work properly. If this is the case, you will need to replace the water valve 00425458. You do not need to interchange the parts between the 14 and the 21 series. Hope this helps. Read More...
