WATER LEAKS UNDER THE SINK WHEN DISHWASHER IS IN

Drainage problem of some sort is usually the cause. Could be blockage before your drain pump, in your drain pump, or in your drain hose. One possibility is that you just installed a garbage disposal and forgot to remove the "knock-out" plug for the dishwasher drain line. Another cause can be that you have not looped your dishwasher drainline under your sink and water from your sink is flowing back into you dishwasher. You must attach your dishwasher drain line under your sink so it is higher then your sink drain lines, creating a trap for your dishwasher. Your drain sump could be plugged, not letting the water get to your drain pump easily. This is caused by not getting loose or hard debris off your dishes before putting them in the unit. Also make sure your drain pump is getting the right voltage when it is supposed to.God bless you

The water will have to be evacuated first. there may be a blockage either in the outlet of the dishwasher or the drain connection under the sink. The dishwasher tries to drain at the very start of the cycle. If this doesnt happen then a new cycle wont start.

if there is still water in the dishwasher take the drain hose off from under the sink and use a large pot or mop bucket and but the unit into a drain mode usually by cancelling the wash cycle if the unit still does not drain.Then use a wet dry shop vac and attach it to the end of the drain hose to remove the water
after the water is gone check the drain pump for any kind of obstructions you may need to replace the drain pump

I would first check where the drain hose from the dishwasher connects to the drain stub under the sink. Remove the hose from under the sink and place it into a bucket. Close the dishwasher door and cancel the cycle to put the dishwasher in a drain cycle. Listen for the drain pump to activate. If water comes out of the hose check the stub where the hose connects under the sink with a screw driver to make sure the spout is clear of debris. If no water comes out of the hose, empty the dishwasher by hand using a plastic cup and when empty remove the hose at the pump under the dishwasher and check to see if there is any debris at this point. Make sure hose is clear from the dishwasher pump to the drain stub under the sink. You will need to place a towel or two on the floor as water left in the bottom of the dishwasher will come out when you remove the hoses. If still no water comes out you may have to disassemble the bump assembly. Not knowing what make and model you have I can't help you past this point.
I hope this is of some help.

Check the following:

* Loose or mis-positioned hose clamp at the drain spur connection

* Rotted or brittle hose

* Split hose

* Cracked joint at the drain spur connection or split drain spur fitting

Bosch has a safety float switch under the dishwasher basin. If water leaks into this area, the float rises and turns on the drain pump to clear out the water in the dishwasher. Hope I explained that ok :)
Anyways, usually a leak somewhere causes this and unless the leak is fixed and water is removed or evaporates, the dishwasher will remain in the drain cycle.

Try adding bicarb of soda/baking soda and vinegar in the detergent dispenser. Bicarb fizzes off hardened particles and vinegar strips off grease and aids rinsing.

Hi.. Its a breather or "vent "and its clogged. Remove the drain tube under the sink that runs from the vent to the connection on the drain( under sink). Clean vent and replace. Please send me some Positive feedback if I've help. Thankyou!

Two things to consider....clean water or dirty water?
Clean water usually indicates the fill valve is not shutting off all the way and the fill valve is "weeping" water in all the time = new fill valve time!!
Dirty water usually is not a dishwasher problem but more of a plumbing issue. Often the sink drain that carries the sinks water outside is not fast enough and some of this sink water is backing up into the drain hose and filling up the dishwasher through the drain hose. The drain from the sink to outside needs attention as this type of a problem indicates a slow house drain for that sink.
The dishwasher drain line should be clamped to the top underneath part of the counter before entering the sink drain plumbing, this may help the water from coming back inside the dishwasher.

although hose is not clogged is it installed correctly?is there what they call a high loop installed under sink( loop up high as possible under sink to prevent both water siphoning out or returng back to machine after cycle complete. when you press the cancel button do you hear the water flowing freely into sink drain, if not sounds like you got somthin in hose or pump assy
