Leaking water at the discharge line/selinoid???

door seal --water line--drain seal need to look under as to where leak is

Check the following.
1. The drain hose has to be discharging at a high enough point to prevent water flowing back into the machine.
2. Make sure your drain hose is not twisted or kinked.
3 . Make sure your drain line is not blocked push a flexible hose down it to dislodge any fat/debris
4.If your drain line discharges into a shared drain with another appliance i.e. garbage disposal make sure it is not blocked.
5. You may have a blockage at the inlet to the pump which would slow down the pumping rate,
Since you mentioned the mushroom shaped float allowing the washer to empty this may be defective.
See the link attached.
Hope this helps.

Bosch Dishwasher Does Not Drain

drain hose leaking from water pump discharge line

When does it start to leak? I mean how much water goes in before the leak starts. I have a problem every once in awhile with mine leaking when the float in the bottom of the washer gets stuck and does not shut off the water. The way to check this is to locate the float, it is near the front left side, and push it up and down a few times to make sure it is not stuck. Try the washer again. If that is not the problem u could have a leak from the drain under the dishwasher. Sometimes the plastic can crack and cause a leak. Also check the discharge line and make sure it is not the problem.

if you have an air gap on the sink from the dishwasher and water is leaking out here into the sink instead of the drain it is probably plugged from there to the disposer or "P" trap in the drain line,also check the sump screen and down in there for food particles still there

kenmore dishwasher will not drain all the water out after cycle is completed

This means that the outlet valve or the drain motor is faulty or their is a leak in the pipe between them and the machine.

Try filling your sink up with water and draining it while watching the dishwasher bottom if it starts fill it is back flowing from the sink drain

hi Most dishwashers discharge used water through a pipe or a hose connected to the drain or garbage disposer under the kitchen sink. If the drain line is made of flexible hosing, it may have cracked from prolonged exposure to hot water. Examine the hose; if it's damaged, replace it. If the hose is leaking at its connections with the disposer or dishwasher, tighten the fittings or clamps at the connections, or replace the clamps. Also check for water leaks around inlet valves, drain valves, and anywhere you see flexible hoses and hose connections. Leaks at clamps can be stopped by tightening or replacing the clamps. Leaks in hoses can be eliminated by replacing the hoses.

hi If the dishwasher leaks, and you know the problem is not related to tub overfilling, the pump, or inlet valve problems, the plumbing connections may be faulty. Most dishwashers are connected to the water supply with metal pipe fittings, and the leak could be at these fittings. If the fittings are threaded, tighten them with an adjustable wrench. If this doesn't work, chances are the threads are stripped or the fitting is cracked or otherwise damaged. In this case, replace the fitting.
