Question about Bosch 24 in. SHU43 Built-in Dishwasher

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...).

THANKS A BUNCH!

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.

Replace dishwasher


Is your DW plumbed into the garbage disposal as many are? Or does it have the drain line running into a pvc opening in the sink drain line? Remove the drain line to see if water gushes out. If no or minimal water leaves your drain line from the DW, then the problem is internal in the DW. Most likely cause is a plugged screen at the inside bottom of your DW, or the pump is blocked. Best way to resolve is to get a wetvac and just suck all the water out of the inside before you remove the DW. Otherwise you will have water splashing out on your floor. If you can see the screen is plugged up after doing so, then pull the screen out and then turn the DW on. If operating normally it will go into the pump out mode first before adding any water. Turn off the water to the DW under the sink first to eliminate any concern about adding additional water into an already filled up DW. Good Luck!

Garbage Disposal is about 2-1/2 years old It is now no longer grinding up potato peels and clog every time! HELP--do we need a new one!!!


1/2 horsepower is the lighter weight model, and if you use it heavily, then it will not work like before.
Another thing to consider is whether the water is draining away completely while you're cutting.
If water and potato peels are both present, your p-trap and tubular drain may need to be cleaned.

Let's go through the whole thing: replacement, p-trap, tubular pipes, everything.

When I worked apartment maintenance, we replaced disposal with same brand disposal.
That way we didn't have to change out sink basket or move pipes around.
How to replace disposal body: Disconnect both nuts on p-trap. Remove p-trap and loosen tailpiece going into disposal.
Rotate connector disk clockwise that holds disposal to sink basket.
Before installing new disposal.
Attach electric wire to new disposal.
Attach dishwasher tube to new disposal. Knock out plug inside dishwasher opening.
Push new disposal up into place, and attach to old sink basket with new connector disk.
Use new connector washer.
Re-assemble tubular pipe.

geno_3245_163.jpg

If this is your home, you might want new sink basket that comes with new disposal because it looks shiny and new.
Buy a tub of plumbers putty also.
Remove old sink basket and clean opening.
Put finger-size roll of plumbers putty around sink opening, and then push new strainer basket into plumbers putty.
Tighten basket from below, wipe away excess putty around sink opening.
Install new disposal as described above.

Tips for tubular pipes:
When taking apart tubular pipes, start at p-trap and take apart as few pieces as needed to do job.
On image above, loosen both nuts on p-trap, trap falls loose, and then work on disposal.
Any tubular drain pipe that gets moved while working under sink needs to be disassembled, cleaned and re-assembled.
Metal pipes have rubber washer >> always use new rubber washers.
Plastic pipes have plastic washers > plastic washers can be cleaned and re-used.
Plastic washers have flat side that goes toward nut, tapered side away from nut.

When reassembling tubular pipe, we use rectorseal on washers and joints.
Apply good amount on washer just before pushing washer in place and attaching nut.
Rectorseal will ensure tubular drain pipes won't leak.

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

I never put potato peels in but in the 3 months I have owned this house it has stopped up twice. Why?


The problem should really have nothing to do with potato peels. Even a cheap disposer should have no problem chewing up things much worse than that.
There are two main things that could be causing your problem: 1. Defective disposer or improper installation 2. Improper usage of disposer (more likely)
I've been known to put entire sinkfulls of waste down the diposer (mine is an ancient thing from the 70s), and I've had a clog maybe once. You have to be conscious of the amount of water that's going down with the waste. Ideally, before anything solid at all goes down the drain you should turn the faucet on COLD full blast and then turn on the disposer. The grinding mechanism is so fast that the disposer shreds the solids and blows them into the drain pipe at a very high rate. If there's not enough water down there to get thrown down the drain pipe with the waste that's when a clog happens. So don't turn the disposer on AFTER putting a lot of waste down there and always do it with a full flow of cold water. Feed the disposer gradually with the waste and let it run until it sounds empty.
When done right, the worst clogs can easily be dispatched with a plunger in three or four strokes. With a toilet the best way to it make sure the plunger is sealed good and plunger with short, fast, powerful strokes. When you unclog a disposer, the clog is almost always in the connection where the disposer discharges into the drain pipe because of the funnel effect. When you push the plunger down the water pressure will go up but the waste will compact tighter and resist flow even more. You want to push the plunger down and let it leak until you get it as far down as possible, then let it form a good seal and give a powerful upward stroke. That'll create strong suction and pull the clump of waste particles back, where they'll mix with the excess water and go right down the drain. If you don't have a plunger, you'll find that for some reason a soda can will work in a pinch.

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.

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...
db113bd.jpg

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...
4cc45a0.jpg

The DW drain loop should be as high as the highest part of the sink...
1144177.jpg
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 DW..it 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 drain...you 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
