Remove the side and top panels of the machine.

On the left hand side you will see a clear plastic panel full of tubes and small tanks. This is the metering tank. At the bottom left of this unit, is a black pipe held on with a clip. There will almost definately be a blockage between this point and the sump. You can either buy and fit a new pipe or do what I did with mine, which was to remove it and clean it with hot water and a bottle brush. Seems to work like new again now.

You'll have to get the machine onto it's right side to remove the lower end of the black pipe from the sump. I drained as much excess water as possible out of the machine by sitting it on bricks, tilting it to the left and catching the water in a dish as it came out of the float hole. Some will also come out of the funny plastic tube which runs across the top of the machine - I carefully removed this first and caught this water in a pan.

Drain the waste pipe and disconnect the water supply.

Replace the right side casing on to protect the feed to the upper spray unit and put the machine on it's right hand side. Once the machine is on its right hand side, fin the water inlet valve and carefully remove its bracket from the chasis of the machine. You will need cross head and a torx screwdrivers - one for each screw. Once this is loosened, push some of the water supply pipe into the machine so you can move the bracket to the right a little to gaine access to the waste pipe. Remove this by removing the two gold coloured screws. This should now give you easy access to the sump end of the black pipe which lead from the metering tank. Remove this and clean it out. Pop all the parts back, stand you machine upright. Reconnect the watre supply and the waste and give it a rinse cycle to test - number 1 on the dial.

Hope this helps. My apologies if any of the take apart is not completely accurate - I don't want to turn my machine over again to check!

    What an absolute genius. Thank you soo much for this. In fact it may not be necessary to remove the pipe completely. just put machine on a couple of milk crates. remove left panel. drain by setting prog to say 4 wait till pump empties all then open door to stop filling. Unlcip black pipe end drain this full into jar underneath m/c. Mine had tons of gunge in it which came out really easily. Job done. Once set up takes less than 5 min. Thanks rup Nickols

I HAVE A LEAK AT THE WATER-INLET SYSTEM, THE LEAKING OCCURS WHEN THE THE DISHWASHER STARTS. THE VENT HOLES ON THE TOP OF THE INLET SYSTEM WATER SQUIRTS OUT DURNING THE FILING PROCESS.


its just the air-gap on the inlet system,sometimes a slug of debris gets near the air-hole in the side of this gap and redirects the water flow,just easily run a screw driver of the right size down the water tube and then try filling it again and see if this helped

My Zanussi dishwasher DE6744 leaks clean water during the wash cycle. The water appears to be coming from the plastic tank overflow holes, left hand side as you look from the front. Any ideas?


I have the same machine and I took mine outside and turned it on its side and removed the clean water feed and all the screws holding the white plastics off and then un-clipped them off and I saw that there was a blue tube that was leaking on mine, I cut the end off and reattached it with a new clip and hey prestow all working now with no leaks.

Dish washer, Water leaks out of right front corner during first


it sounds like your machine is over filling. the gasket is not supposed to be under water. check the overflow float inside. it looks like a little hat or cone. it should move freely up and down. if it is stuck down, your machine will fill up too far and then leak. good luck

Bosch dishwasher SHU4326uc/u12 is leaking from the door. How to change low door sealer?


I have had the same problem and finally stumbled upon the answer today!

If you are looking inside your dishwasher, look mid way up the right side wall and there is a valve/hole...if that hole is covered up (e.g. cutting board, ect) it will cause water leakage.

Weird huh? But that recommendation is coming straight from the Bosch headquarters in Canada. I would not have believed it otherwise, but I have read this solution twice, and now myself, have not had a leak since I stopped placing things over that hole! My model is SHU3326UC.

Water keeps running into dishwasher causing overflow


I had a diswasher with thils problem several years ago. The problem was wiith the plastic float at the bottom. It had hardend greese buildup that kept the float from moving freely. Removing the float and cleanning fixed the problem.

Leak from dishwasher fill funnel


Hi . the air gap is required by law, to have it there.to stop water in the tub, to end up in your water system, which would never happen. try setting the pressure down, and use the dishwasher. it should work fine . turn down taps ,till it stops leaking . should be ok

Water pump works from the minute I press the main switch


I may have had the same problem. At the end of a normal wash cycle the pump would stay on for hours or even days - I would have to power off, and then keepp trying to power on until it had eventually stopped. The pump operates even with the door open.

Problem is caused by a small float which senses the water level in the dishwasher, floating up and operating a microswitch, which turns on the pump to pump the water out. Obviously, if the dishwashe is filling up for some reason, you want the pump to operate even if the door is open. The float is in a small chamber - a very snug fit, with a hole in the bottom which is connected to the main pipework in the machine. There is another chamber next to the flot chamber which is also connected to the pipework. When the water level rises too high, water from this second chamber overflows into the flot chamber, raising the float and operating the pump. The water level then drops as the water is pumped out. The water level in the float chamber should also drop, but didn't on my dishwasher because the hole in the bottom was blocked (with old soap suds and grime I assume). Hence the pump just stays on. I assume in my case, the water flowed out very slowly, and eventually the pump stopped.

To fix it, removed the left hand side panel (2 screws on the front door lip. The back of the panel is just hooked on some raised bits of plastic). This exposes all the pipework, and the red float can be seen in it's chamber. I removed an extra couple of bits of plastic near the float chamber whilst I tried to work out what to do - but this may not be necessary. You will have to try for yourself. I couldn't get access to the hole to poke something in to unblock it, so I poured sink and drain cleaner into the flot chamber, topping up as it drained away, leaving it for approx. 15 mins. I think thick bleach would also work. Note: this cleaner won't be very good for any metal inside the dishwasher, so run 1 or 2 wash cycles to clean it out.

Maybe the dishwasher cleaner advertised on tv would have worked i.e. the stuff you put in the dishwasher on an emty cycle to clean out all the internals. I haven't used it, but it would be easier than taking the dishwasher to pieces.

Hope this helps

KENMORE DISHWASHER WATER DOESN'T SPRAY.


If there's no water entering your dishwasher, check these:

Water-inlet valve
Float switch
Water-inlet valve
The water-inlet valve lets water enter the machine. If this valve is defective, you need to completely
replace it. It's usually located behind the lower access panel on the left or right side. It's the device
with the main water line (usually copper) from the house, a rubber tube to the dishwasher, and two
wires attached to it.

Float switch
The float switch is a small electrical switch that's located right below the dishwasher "floor."
Above the switch, on the inside of the dishwasher, is a plastic cylinder that floats up as water fills
the dishwasher. If this switch is defective, or if the plastic float gets caught or trapped in the raised
position, the water can't enter the dishwasher. If the float switch is defective, you need to replace it.

Dishwasher will not fill with water


without a brand or model number its hard to be sure, but some types have a float cut out switch inside the washer. Its on the bottom inside and kind of resembles a plastic mushroom. The top should lift up and down easily. detergent will clog it up and keep it from moving. Just clean all the soap caked on it and move it up and down to see it it pushes a little switch underneath.

Water leak on fill cycle


this type of fill mechanism is a pain in the butt and causes many problems. a likely cause is a blackage in the transparant pipe on the rhs of you picture about 1 inch diameter or a little more. recommend you use a dishwasher cleaner 3-4 times as year
