Fixya login Hi whenever I use the dishwasher or washing machine or if I just empty the sink water leaks from behind the wall and onto the floor. it floods. I assume there is a blockage. Is this problem fixable by a handy person or do I need to call a plumber cheers

Here in Thailand the washing machines have no drain pump and the drain hose must be run at floor level.
If you live in the UK or USA for example, the machine will most likely have a pumped discharge and the hose is normally hooked into a standpipe behind the machine

tear out the wall and fix the leak

Hi Sharonl100,
Yes you will have no problem if you use the sink, I would however recommend that you lower the drain hose after each wash to the floor (emptying into a bucket or somesuch), and siphoning any remaining water from the machine.
Kind Regards

A leak at the back of a washing machine can come from several sources.
It requires a good investigation.
Here are some of the first area to look at that are on the outside of the machine

1 Hot and Cold Fill Hoses may not be tight enough. So water can drip down the hose, or back of machine onto the floor
2 Drain Hose-Usually about an inch or so in diameter. Hose in new machines should not leak itself, but if it is not mounted or attached well enough into the drainage plumbing mounted on the wall (The box with the Hot and Cold Water Shut-offs, it will leak or splash water onto the floor during the drain cycle.
3 Damaged plumbing in the wall can seep under the wall and end up under the washer. This is very rare, but I have seen it.

4 There is a filter mounted behind a panel on the lower back side of the machine. It is possible a leak is occurring from that area. Take off the cover and see.

If the above don't handle it, the next step is for what is not easy to detect. Leaks inside the machine. You will need to go into it and LOOK with your eyes and a good flashlight.
Hope this helps,
Best, Mark

Hello,
If you can supply the Product number or model number I would be able to help.It would not be a major expense for a new inlet valve.Check if the drain pipe from the dishwasher if going into a pipe outlet in wall that it is not too far down into pipe as this could cause it to syphon back into unit.Also if drain goes to a sink outlet make sure the drain hose is above any other outlets,you could tie hose up into a "U" shape above outlet this will stop waste from sink getting into Dishwasher.

Hope this helps.

Take of the side panal right side facing the front as this exposes more of the bottom of the machine. Check for any leaks around the pipes and the sump. While side is of turn machine on and see if you can spot any water and make note where abouts in the wash it is as this will point you to where leak will be.

If you let it sit with vinegar and it worked after for a while that tells me it may be plugged up with grease. Might be worth while trying to clean it out with Drain O a drain cleaner. Make sure its washed clean after. Grease and dirt builds up after a while in all machines. If vinegar works might be worth cleaning more often.

Begin at your sink drain that the dishwasher drain hose connects to. Disconnect the hose and check both directions for anything plugging the connection.
Make sure the drain hose has not become "kinked"
(After you have emptied the water from the dishwasher) remove the lower spray arm and the filter in the sump area. Look for obstructions and remove all debris. Rinse the filter thoroughly and reassemble.
If you dishwasher has a timer on the front of the dishwasher that you can manually turn, start a quick cycle with no DW soap and empty.
Allow the water to run in for several seconds and then manually (slowly, gently) turn the timer knob until the DW should begin draining the DW. Listen closely for the sound of the pump motor running.Is water properly draining out of the dishwasher into the drain?
After you have done these things, please post back here and we can take the next steps. OK?

1. open the bottom panel 2-4 screw
2. take a flashlight and turn the machine on
3. see where it come from
4. if you need take the unit out a bit from the counter
5. check it all around to find the sorce of the leak
6. good luck its EZ :)
   

First see that the exit hose behind the machine is at the correct height, before coming down into the wall standpipe or your sink. Your machine pump pumps water over this height, about 2.75 feet above ground level. Possible there is a water level height marked behind your machine.

If water flows out when machine is off, possible your inlet valve at top of machine is defective...............can be replaced easily.
