Bosch Dishwasher SHU43C Not Washing Dishes

Hello.....
My Bosch Dishwasher shu43c will fill, release detergent, cycle through the correct time, and drain. But will not turn arms and clean. Removed arms and racks to see if that is the problem. Opened door quickly to see if water flowing through jets....no luck. Clear plastic tub on right side of dishwasher does not appear to have water flowing through it either. (Dishwasher is pulled out of cabinet space to see all around).
Thanks in advance

    Hello....

    The DW fills, to the best of my knowledge, like it should. It drains, to the best of my knowledge, as it should. The timer allows it to run through the cycle like it should. It is just not cleaning the dishes. I opened the door during the cycle and there is no water on the walls or dripping from dishes. DW is not leaking....No water in pan under DW or on floor. I think....after the initial fill, the arms start and more water is added due to the water being used during the wash cycles. It does no add any more water than the initial fill. Thanks for the quick response!!

    Check for plugged nozzles:



    I feel im pretty handy....BUT.....What nozzels?......there is a silver box on the right side behind the panel. Looks like a motor of some sort. Has wound copper like a motor. Does not turn!....ever!....I blew compressed air backwards of the way water flows into where the lower arm enters the body of the DW and still no luck. Think its more than a simple problem.....just my luck!!! If I had a service manual....I might try more but I am at my end I believe

  • instag8r67 Feb 08, 2009

    Ill let you know the outcome!!....Any sugestions about doing it myself rather than a service call? and a good place to get the parts online maybe?

  • instag8r67 Feb 08, 2009

    Can this be tested with a multimeter to see if it is really the problem?

  • instag8r67 Feb 15, 2009

    Its dead! Where can I find a repair manual? Found the part jsut need to see what I need to do about replacing it.

    Hello....

    Its me again. Found the part fairly cheap on ebay. But the wiring does not match up. I wish I could attach pics to show the difference! Bosch says its the right part and the company i bought it from says its correct also. Any suggestions? I want to make sure it is the right part before I try to fix it....I am tired of dishpan hands!

  • instag8r67 Feb 26, 2009

    Let me try to draw you a mental picture:

    OLD: 4 terminals with wires left to right numbered 3(White), 2(empty), 4(Pink), 1(Black)

    NEW: 3, 2, 4(no terminal), 1

    there there is a round cylinder on the left (A "Cylinoid" im guessing) and two terminals with wires leading to it:

    OLD(three wires): Blue and black on one lead and another black on the other lead

    NEW(2 wires): Black and white on separate leads

    Looks like wires come from the #1(white) and # 3(Black) terminal

    I hope this helps

    Check the pump and for proper water supply. Are you leaking water from anywhere?

    That motor should turn and if it doesnt then it needs to be replace. That motor controls your arms to spin and produce water. Replace that and the system will work perfect

    There is the link to order parts, and no need to contact a tech, you can do this yourself, just make sure water is shut off and the power is unplugged and dive in. Only a few screws and then some wire swap

    Yes you can check the leads in the back while pluged it, but you know it is dead since it is not turning, should be 115 volts there abouts

    There is the website. You just need to figure out the rest of the model number

    Is there a wiring difference or nothing marked on the new one like the old one had?

The water does not circulate throughout the washer. Is the pump bad? The full cycle will run without cleaning.


Before we jump to conclusions, you can try to clear element that discharges the water. The wholes in these units can become clog do to the detergent as well as food. Most Bosch units allow you to unscrew these pretty easily. Blow through them, or use a plastic tooth pick to clear any obstructions or both. Before you reattach, turn on dishwasher and listen to hear how much water is shooting out at the discharge points. Most Bosch have two discharge points one for the top and of course one for the bottom. Reattach units and Run dishwasher.

Should this fail it could very well be the circulating pump.

My Bosch SHU43C will sometimes make a loud noise


It may be more cost affective to just replace this unit. the circulation motors that are used in these dishwashers are not reliable. the wash impellers seems to have issues dealing with staying attached to the drive stud and shaft. this will cause the impeller ti shift inside the housing, causing noise and jams.

A new circulating impeller kit will cost about 100 dollars and, labor for this type of repair is 80 dollars an hour.

Our Bosch SHU43C Built-in Dishwasher sticks in the drying cycle.


I have the same dishwasher and started experiencing the same problem last week. It is now fixed (at least for the moment). Here's what I did first. I checked the drain pan under the machine for water(none), the heater for continuity(okay), the float for binding(none), and the float switch for proper functioning(okay). I tried turning the ckt breaker off for a couple of hours to see if that would reset the control module(no effect). I then dissasembled the front door and removed the control module. I had previously read about the common problem of a cold solder joint on the heater relay pin on the control board. My heater was working and the joint looked good but I resoldered it anyway. I reassembled everything and it worked perfectly! My conclusion is that it was either a cold solder joint that was somehow causing the problem or a connector issue that got resolved during my disassembly/reassembly. Hope this helps.

Bosh shu43c never stops running.


If you have a Bosch shu4300...check this site.

http://fixitnow.com/wp/2006/06/09/bosch-dishwasher-takes-forever-to-complete-a-cycle/

My issue was a heater fault and fixed the problem by resoldering a bad joint. Works fine once this was fixed.

Bosch SHU43C installed in 2003


My Bosch SHU43C had the same exact problem. I found the below solution on this site. Perhaps you already seen it.

My SHU43C is just over 3 years old. I had a similar problem recently. First, there were a few floods. Then, the Bosch only drained non-stop. Even when I used the Cancel Drain buttons the drain pump would run without stopping. When I tried to run one of the cleaning cycles, no water entered the machine. Corrective: I removed the base plate, and saw that the red plastic floatation device was in the up position. Using a flashlight and a wooden spoon, I lightly toggled the red float stem down. I pushed regular clean cycle and kept toggling with the red float stem until the rinse water started to enter the machine (turning the red stem seems to also actuate a step in the program). Now the dishwasher runs normally. Voila!

SHU43C


Ours does this occasionally. We always pop one of those dishwasher cleaner bottles in which gets rid of the grease that accumulates, but the best thing to do is remove the arms that do come out with a bit of force and you'll probably find that the holes are blocked - normally it's fruit pips. It takes a little patience and quite of lot of shaking to get them back out of the hole in the middle, but that should solve the problem Hope this helps Andrew

Bought the display unit and water will not work.


hi there the low humming noise that you are getting sounds like the fill valve, this could be due to you perhaps not turning the water back on after fitting the new dishwasher or the fill hose being kinked when the dishwasher was put back ,hope this is of some help to you.

Sounds like the control module is out -- cost about $100 (I am on my third). I got a "lifetime" warranty when buying my second one. If you are handy, you can replace it yourself. You can call Bosch to confirm this (I did). It mounts inside the door. Mine is a BOSCH 5316.

The draining problem may mean a clogged drain hose -- you have to check it all the way back to either the main drain or the garbage disposal (if you have one). This may be what forced off the impeller wheel.
