    Water is pouring out of the back of my Haier countertop dishwasher after it fills to wash. The water source line doesn't leak and neither does the drain hose or front door.Where is this water coming from?

    My dishwasher leaks from the exact same part that Jim described. Does anyone know if one can just order this part?

I use the tablets too. A simple change of soap won't create or cure a leaking dishwasher. I own the same HDT18PA dishwasher, also known as a POS.

Where is the leak coming from? You will need to remove both the shell and the lower pan from the dishwasher to be able to find this part. It is a water guide from the pump body that connects to both the lower spray head and the upper spray head. This is the MAIN water plumbing, once the water is within the dishwasher.

The part is manufactured from TWO pieces of plastic, and not melted together very well. The pressure from the pump is considerable, and these pieces of plastic have a large amount of flex applied from the INSIDE to them. They WILL FAIL, it is only a matter of time.

But in a statement to the build quality of this Haier, not even the BRICK that you will find zip-tied to the inside of the casing will be damaged by this leak... Only your counter, cabinets, kitchen... Those will all suffer from the Noah-esque floods that will be visited upon you when it fails without warning.

I've already taken this thing apart and rebuilt it once, using a heat welder to REALLY seal this plumbing together. It lasted 2.5 years of 1-2 times per week usage, and has now failed again.

I will not be replacing this in it's built-in location that I designed in my RV until it is either fixed with a METAL part that I will have to fabricate, or I find a new dishwasher.

I fixed Haier portable by removing the flat water tranfsfer pipe that split on the side. Dried it out and then drilled 6 holes along the edge and glued it with epoxy glue. I then put 6 little bolts through to give it a mechanical seal to resist the pressure. See the picture to get a better idea of what I did.
Once the bolts were in and tight I ran epoxy into the gap inbetween the two halves to make sure it was well sealed.

I drilled and epoxied the other side to make it would not fail in the future. A mechanical seal made by the small bolts is needed to resist the pressure on the flat surface - the expandinng force is great due to the large surface area recieving the pressure.

Be sure to put some of the epxoy under the head and the nut of the bolts to seal them.

Good Luck!

Ds603 flood switch has been activated


The flood switch is at base of dishwasher housing under the drawer. Water leakage has occured to trigger this. Turn power off to dishwasher and take the power chord out. Pull the drawer out and use towels and hair dryer to dry the base. Put drawer back in and reconnect. Should work. Need to find the cause of leak. Either damaged lid seal or leaky hoses. Sometimes too much foam in detergent can cause it. Use recommended detergent and appropriate quantity per user manual.

18 month old kitchen aid kudc10fxss leaks water at bottom of door


Someone may've accidentally put liquid dishsoap rather than dishwasher soap into the fill cup. The bubbling will cause lots of foam to rise up above the float-switch without actually raising the switch (shutting off the water supply). Lots of helpers on the web recommended draining, wiping out the foam, pouring in a cup of vinegar and a handful of salt and running the rinse cycle a couple of times. It worked for me!

Bosch exxcel auto option - Have not run it for a couple of months. Turnit on al all it does is pump out


Hi,

The usual reason for this is that water hes leaked into the bottom of your dishwasher under the washing compartment. This has caused the float to rise and trip the switch which activates the Aqua-Stop / anti-flood protection system. This also closes the solenoid (water control valve) to stop water entering this dishwasher. You may already have had a small leak before you stopped using it.

The only way to check this is to remove the washer from under the counter (disconnect power and water supply first) and tilt it backwards about 15-20 degrees. Water should run on to the floor from under the washer so I suggest putting some old towels down first. Once the water has been drained from under the washer, you can use it again, but it's not advisable if you have a leak and this really needs to be investigated.


If there is no water from under the washer, you may have a faulty float switch or possibly a faulty control module.

Hope this helps.


Regards,
BElectric

Keeps coming up with fault "F1"


Is that in one drawer or both?

Generally it means the flood switch under the drawer (inside the housing is activated). This means water is leaking from somewhere - foam in detergent, cracked or crinked hoses, door seal leak etc.

To fix, take the drawers out from housing and dry the flood switch located in the centre of the housing base. Need towels and hair dryer.

Make sure the power is turned off.

Fisher Paykel Dish Drawer flood alert switch


Switch the main power off and on after a short time. If the error does not go away then you have water collection in the base of the dishwasher under the drawer.

Take the bottom drawer out and try to use a couple of towels to dry out the base plus use a hair dryer. (make sure the power is turned off at the mains switch). This should dry out the flood switch.

Now about the reason for water collection - could be kink in drain hose, water leak from drawer seal, foaming due to incorrect detergent.

You have not mentioned if the error is occuring in both drawers or just one.

Dishwasher keeps flashing F1


F1 on your dishwasher is the fault code for leaking inside the machine. the water has caused the flood switch to activate. have you put any detergent rather than your normal dishwasher detergent into the machine? if you have, the water probably leaked out of your overflow, if not, then you have a leak on the top drawer or bottom drawer. the easiest way to check is to leave the machine off for a couple of days until it drys then turn on the bottom drawer to go thru a cycle.if the F1 comes up again then the problem is on your bottom drawer. if F1 does not come up then try the top drawer. please reply if you require further help.

Drain pump won't turn off


Hi,

The reason the drain pump continously runs is because it is trying to remove any water too avoid any further flood as there is a flood in the base of the unit which activates the float switch and constantly activates the drain pump until the water has gone. Isolate the unit at the power switch and remove the bottom panel under the door panel. Dry up the water as best possible with a towel. Run the unit again and check for any water leaks. You may just have over sudded the unit with too much detergent. Only use 2 teaspoons of powder. To start with while testing don't use any detergent. Good luck

Hope this helps.

Slight water leak towards end of cycle


Did u notice the Quantity of detergent used? If the leaking water is soaping, it is an indication of excess detergent used that cause the leaks. Reduce the detergent n observed the DW running, or run the DW without detergent several times to remove all residual residing inside the washer.If not check the door gasket or change the door gasket.

Dishwasher leaking around the bottom of the door


I had the same problem in 2004, lots of Bosch trained repair techs, calls to Bosch, and the appliance dealer we purchased it from with no answers. Our kitchen cabinet bases were ruined by the flooding that occured. After months of trying to get help I insisted on speaking to a supervisor that told me it was my fault for putting a flexible cutting board on the right side a blocking the vent. I told her that no where in the manual did it mention this issue and none of their trained techs were aware of this flaw in their design. When I asked about getting my cabinets repaired she said that was not an option. When I mentioned possible legal action her response was "good luck with that". Here it is 2009 and they recently called about a possible fire hazard recall for the control panel. The Bosch trained tech that came out to complete the repair knew nothing about the vent/flooding issue.
