Bosch DW model # SHU43C05UC. When dw is turned on it is supposed to pump out whatever is is sump. Pump never shuts off. So it never goes into a wash cycle.

I think that # 4 is the solution to your problem. Something isn't right with the world, the DW is thinking. The sticking float seems like the problem here. If not, consult the owners manual on the error message you receive if any.

Is their debris in air gap or in the bottom of the DW, where the drain is screened?

1. The air gap is usually located on top of the sink. Lift off the pretty cover, and unscrew the top cap nut. Is there rice and debris there? Remove it then. Reassemble and check it out.

2. The DW drains to the bottom of the unit where the pump is. This area is screened off so that the pump doesn't get clogging debris in it. is their leaf lettuce and stuff covering this? Remove that debris. Some times this area can only be accessed by removing the bottom spinning spray head. It comes off with a nut, possibly this nut is reverse thread. Reassemble when done looking for debris.

3. Is the drain line between the DW pump (located under the DW) and the waste pipe kinked? This line is a plastic corrugated line about 7/8" around the outside. It is a pumped waste and won't work if it is kinked, so unkink it.

4. Is the float stuck. This is a device on the bottom of your DW that tells the DW how much water is in the bottom of the DW basin. It looks like a mushroom. Gently move it up and down. Does it move freely or is it stuck? Unstick it.

Good luck.

Continuous run of DW "drain pump" is common problem, with simple solution, and without "pulling" the DW!

Because the problem is likely a "stuck float riser assembly", a mechanical "glitch", from crud build up, I recommend trying one "might get lucky fix" first.

Look up above the door and remove (usually two) screws holding two metal "tabs" to bottom of wood counter. This should allow you to "rock" the unit a little. This might allow the float assembly to operate.

A. You have removed and cleaned the screens to the pump inlet and have manually added hot water which the pump removes but the pump just continues to run, even when you open the door? You should still be able to use controls to shut unit off. If not, you should be able to turn DW off at circuit breaker panel. Find and open the breaker any how, because "I'm sending you in!"

There are two sheet metal "plates" about 4 inches high, 24 inches wide below the door on Bosch (and others) dish washers. Remove both, usually they can just be carefully removed.

Lay with face on floor and use flashlight to look "up and into" the left bottom side of the DW. About a foot into the bottom left side of the unit look for a red or orange (usually) plastic rod about the size of a pencil rising vertically out of a thin plastic "tank". This is a "sump" of some sort (???) and the bottom of the rod is a "float". The top of the "pencil" activates a micro switch. Junk in "tank" or on micro switch stops rise of the rod which keeps pump running.

Carefully, manually lift the orange rod with a long wooden spoon. Several times. You should hear the micro switch click. Don't be sticking screwdrivers or anything metal in there. Even with the power off.

Turn breaker back on. This may solve most common problem in first five years for many brands of dish washers.

Good luck.

ck the drain hose ( from the disposal to dw pump . ) you can not run dw with water due to the pressure sw . ck the drain pump also you can use a jumper test cord its 110 volts. .. may be the pump is bad .

ther is poss water in plastic base or float is stuck.

inside the dw remove all filters and in the sump there is a cover over the impellor with 1 self tapping screw remove and there could be a object stopping pump.

OK, first using a sponge and bucket, drain out all the water of the dishwasher (DW) as you can. You can also use a towel too.

Check the discharge/drain cover at the bottom of the DW for any obstructions. Sometimes small pieces of all sorts of things get sucked into the drain port.

There should be a protective shroud/cover over the drain and you might have to remove a small hex head screw to get into the drain sump inlet. Some can be popped off without any tools.

Once you have the cover off, be VERY careful in probing the drain area trying to see if there are any small broken pieces of dishes or glasses that may have gotten into the sump area. You'll want to use a towel or sponge to get the water out of the sump area.

If you don't get anything out of the sump drain, it could be that the obstruction has worked its' way into the motor disposal impeller and you'll have to remove the DW from under the counter in order to get at the motor and pump assembly. This will require possible disconnection of the water supply line, AC power line or plug, and the drain line going to the sink or disposal.

Before getting into removing the DW, you can also check the drain line for blockage by disconnecting it from either the sink drain connection or disposal and blow into the line. If it's not clogged, you'll get air coming into the DW. If not, then the drain line is clogged. Also check the Air break connection, mounted on the sink, (if so equipped) and clean it out. You can also pour warm water down the Air break to verify that the line is clear.

If this doesn't work, please check my other solutions under dishwashers for a complete step-by-step for getting to the discharge pump section.

I've seen blockages occur fairly often on these models and it's usually caused by broken bits getting into the discharge pump and jamming the impeller. Once removed, normally the DW will work fine, unless the impeller has been totaly chewed up by the blockage, then you may have to replace the discharge impeller to get it able to pump out properly.

Hope you found this very helpful and best regards!

Turn off the hot water supply to the DW. Take a pot or pan. Fill the DW tub with COLD water, pump it out. Repeat this COLD water and pump out several times until the suds are gone. HOT water only makes the suds worse and prevents the pump from expelling the water.

From your description, I doubt that the problem is door latch is the cause.
The first thing that a modern dishwasher does before it begins to fill with water is run the drain pump.  It appears that this DW is not progressing to the next cycle (inlet water) and because the pump runs even when the door is open, I agree that the controller card may have failed.
If possible, inspect all the wire connections (remove main power before you do this) ... if there is a loose connection, the controller could do odd things.
Good Luck!  Please report back what you find, OK?

there is a new product out that actually filters the water going into your dishwasher. I use to have ugly,white and cloudy looking glasses until i installed this product. after the first load my glasses looked fantastic!!!! its affordable and you can get it at dishwasherfilter.com.

I have a Bosch SHX46B05UC/14 and it stopped functioning right. It filled, it ran, it drained, it sounded okay, but I finally determined there wasn't enough circulation pump pressure to swing the spray arms. Turns out the problem was a pump pressure adjustment screw, accessible under the kick plate, had backed off--now if I can only figure out how to set it properly, low enough to clean the glassware, high enough not to break the pots and pans--or is it the other way around. I also found some beans in the drain sump (easy to remove cover plate from inside with a torx driver, large object trap not locked down properly and a riser for the upper spray arms not press fit sufficiently into pump outlet (I wonder if I blew the line while setting pump pressure. I AM looking for guidance on how to properly set the pump pressure, for the moment, I simply turned it into its spring loaded range and cranked it down a few turns.
