Question about Bosch 24 in. SHU43 Built-in Dishwasher

1 Answer

Water won't fill

Unit working 100% ok.  Potato peels clog disposer.  Drain pipe is cleared.  Meanwhile, dishwasher (DW) filled with water and overflowed onto the floor.  After drain cleared, the DW turned on, and drained, but would not start the water flow.

I have read about flow switches and floats, etc. but I don't know where any of these things are on the unit.  Some mentioned a "tray" that was filled with water...well, where is this tray?

I needs steps to take, and locations of the things we are talking about (do I have to take door off, pull out unit and look on the back, accessible with panel removed...and where and what does item look like...).

Re: Water won't fill

When facing the dw pull it out from under counter and on the left side there is a panel held on with 2 screws. take that off and under there are the float switches for the overflow. those switches is what causes the pump to run all the time but do nothing else.

The dishwasher won't drain completely. Leaves a little water when finished.

If the heater element in your dishwasher is working correctly, and there is still water left in your dishwasher when the cycle completes, you may have a clogged drain pump (located beneath the dishwasher). You will need to remove the dishwasher and disconnect the drain pump hose to check for clogs. You may also need to remove the drain pump and check it for clogs or correct operation. If the drain pump is found to be bad, replace it, else clear the clog and try again. If you drain hose is going to a garbage disposal unit, check the hose connection and check inside the garbage disposal unit for a clog. You may also want to check the hoses for a clog under the sink if your dishwasher is connected this way.

Not filling or draining

The drain motor (pump out motor) in line with the outlet pipe could be faulty. This motor must spin (to pump out water) in the drain mode. If AC (mains)voltage is across motor in pumpout mode and the motor does not spin indicates that the motor is open circuit and needs replacing. Has one of the 2 motor push on electrical connections dislodged?
Is the outlet pipe obstructed?

Our Asko D3250 dishwasher is brand new, and it fills up and drains and fills again and then the water inlet fault flashes. It doesn't go past this point.

this sounds like a improper install ! ck to see if the drain hose outlet is lower than bottm of tank. it should drain to the disposal . and have a drain loop under sink .. the dw prosser is sensing that the drain is longer in time so it flasher inlet fault . . elevate the drain and try again ..if it drains to a lower use a stand pipe or a siphon brake . in the install .. mm

Dishwasher won't drain, the pump seems to be working but it's like it's clogged or something, any ideas?

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!

FDW60 has standing water in the bottom and will not fill up

You most likely have a stubborn clog in your kitchen drain. Try filling the sinks with warm soapy water and then letting the water drain while also turning on your garbage disposal. Sometimes the extra water pressure will help push the clog through.

Once my dishwasher completed the cycle there is no water but after two or three days the bottom of the dishwasher fills with the dirty water. what could be the reason? I have garbage disposal and one pipe...

You must have your dishwasher connected directly to the garbage disposal and not through an air gap. What is happening is when you disposal fills with water it is siphoning through the drain hose back to the dishwasher. If you sink has a spare hole on the deck install air gap and run dishwasher drain through air gap first. Otherwise make sure you run Garbage disposal often so that water does not get slowed and build up inside.

KitchenAid Dishwasher fill up with water after use

Hi BB,
There are only 2 places the DW can get water from. One is the drain line and the other is the supply line. We need to eliminate one to diagnose the problem, OK?

The first picture is a drain hose gone wrong...

Inspect your drain hose. If it looks like the pic above, you gotta fix that. Even IF that's not the problem right now... it will be in the future (and MAY be contributing to the problem now). You'll need to loosen the clamp, remove the drain hose from its' fitting, pull as much slack as you can get from the DW and then make a "loop" in it before reconnecting it. Like this...

The DW drain loop should be as high as the highest part of the sink...
I know that you have done a lot of experimenting in an attempt to figure this out. Just make sure that the drain hose is installed properly to eliminate it as the cause of the flood issue.

After you've made sure about the drain hose, leave the DW alone overnight. If you see water in the tub the next morning, you definitely have a failed valve on your DW. Since it's new (less than a year?) the valve is under warranty and will be replaced at no charge.

Hope this helps. If it's out of warranty let me know and I'll do the part look up for you and provide detailed replacement instructions, OK?

Seems my drain is plugged on my dishwasher it is the magic chef 4500b unit and i now have water all over my kitchen floor. i cant seem to find the product du4500b  so i entered the du2000 , either way...

Ok there are several problems this can be caused from...
1. there is usually a float device (I'm not sure about this model) that floats up and turns the water flow off when an appropriate amount of water is injected into the DW...sometimes these get gummed up with soap and gunk...look in the DW and see if such a device is present (usually front right side) if so you should be able to lift it and inspect it for gunk...if no gunk is present push the float up and down and listen for a "clicking" noise and make sure the float returns to its up position (spring loaded) and after you have evacuated the water turn the DW on and start to fill see if the water shuts off automatically after it has filled (this is most likely your problem).....
2. Another problem is that often if dishes are not rinsed and lots of food has accumulated around the bottom of the can obstruct water from draining and since the drain cycle is on a timer...all the water will not drain out and during the next cycle...(and usually only if the float is not functioning) it will overflow. So the odds are you are going to have a float problem.
3. Also in my 35 years of appliance repair I have seen maybe 2 DW drain lines clogged and usually it is right where they attach to the washer...due to the aforementioned food accumulation. Turn the washing machine timer through its cycle from wash to rinse or whatever is necessary to get it to should here a door or valve click open and water running into the garbage disposal side of the sink...if this is the case the drain line is good.

Hope this helps...get back to me if not....The Fang
