The seal for the pump drain valve shaft leaks

HI,
If you're just looking at the machine the problem is not going to be fixed..
and now the question: in witch cycle is leaking?
fill, wash or rinse?
can be...for fill...one hose from filling is broken.
for wash...mechanical seal from wash motor, the plastic manifold,one gasket.
rinse..manifold or hose for the rinse...rinse pump..
for drain..solenoid for drain, the hose for drain..
Anyway you must open the machine first of all and see.

Good luck

HI,

If your dishwasher leaks, check these:

Main tub seal
Door gasket or seal
Water-inlet valve
Hoses
Main tub seal Note… If the main motor of your dishwasher is mounted vertically, beneath the center bottom of the dishwasher, the following instructions probably apply to you. But if your motor is mounted horizontally, the pump isn't serviceable--you need to replace the entire pump and motor assembly.

The main tub seal is beneath the drain impeller. It prevents the water in the dishwasher from leaking out near the shaft of the motor. To get to the seal, which is inside the dishwasher, remove the:

• Lower rack



• Spray arm



• Spray arm support



• Wash/drain impellers

Then pry the seal out of its housing and replace it.

Door gasket or seal Over time, door gaskets and seals harden and lose their ability to seal properly. You can't repair the seals. You need to replace them if they've begun to leak.

Water-inlet valve The water-inlet valve, itself, seldom leaks. But, the water-supply line from the house and the rubber tube leading from the valve to the inside of the dishwasher may leak. Tighten or repair/replace these as necessary.

The water-inlet valve could mechanically stick open. When that happens, the water continues to flow into the dishwasher, which then floods your kitchen. Turn off the water supply to the dishwasher, and replace the valve.

Hoses Behind the lower access panel on your dishwasher are several rubber or plastic hoses. If the leak appears at a connection, try a new clamp. If that doesn't work, replace the hose.

If your Dishwasher is not Draining check the following

PISTON VALVE

On some dishwashers that have a filter (screen) along the back wall of the tub have a piston valve. The piston valve commonly causes dishwashers not to pump out. if your dishwasher does have a filter, remove it. Now remove the piston valve located in the center behind the filter. Now to check the piston valve, press up on the spring. Once done the piston should stop up the hole in the top of the valve. When a piston valve, is bad the piston dissolves to the point that it can no longer stop up the hole, in this case replace it.

DRAIN SOLENOID

Another common problem on some dishwashers that will cause it not to drain properly is the drain solenoid. To check this, first disconnect power from dishwasher then remove the bottom panel of dishwasher. Once off, you should see the drain solenoid attached to the main pump then reach under the dishwasher and push down on the solenoid. If it will not move down it is bad and needs replacing. If it will push, down most of the time it is good but not always so follow these steps as well. Reconnect power to dishwasher, now start the dishwasher in to a cycle. If you have a mechanical timer turn it slowly until the solenoid energizes. If you turn the timer all the way around and the solenoid never energizes replace the solenoid. If you have an electronic control, start the dishwasher and wait a few minutes then push start/reset then the drain solenoid should energizes, if not replace the solenoid. At times the timer will cause this part to go bad especially if its melted or frozen down. So you may have to replace the timer as well.

CHECK VALVE

If your dishwasher is not draining properly, the check valve may be your problem. The check valve will be on some dishwashers with both a separatedrain pump and a drain solenoid (note if you do not have both you will not have a check valve). The check valve will be located where the black hose connects to the drain pump. To access the check valve, you must first remove the water from the dishwasher. A Wet-Vac works well. After the water is out, disconnect power to dishwasher. Now remove the dishwasher from under the cabinet. Now remove the black hose (even though you removed the water you will still have water in the pump so be ready).Once off you should see the check valve. It's the little red rubber flap. If it is torn off, the flap may have gone down the drain but you still should see the red ring left behind, in this case replace the valve. Sometimes the check valve will swell up and hang in the pump, if so replace it.

DRAIN PUMP

If your dishwasher is not draining properly, the drain pump may be your problem. As stated before, not all dishwashers will have a drain pump. To check this, First check to see if it is getting power. You should have 120 volts when the dishwasher is put into a drain cycle. If you have power and the pump does not run remove the pump and check for obstructions if none found replace the pump.

DRAIN HOSE

If your dishwasher is not draining properly, the drain hose may be stopped up. To check, remove all the water from tub. A Wet-Vac works well for this. After the water is gone remove the drain hose (even though you removed the water you will still have water in the pump so be ready) from the house plumbing and the dishwasher. Check for obstructions and remove. If you just installed a new garbage disposal check that the metal knockout was removed. Check the air gap if this is not right your dishwasher will siphon water back into it.God bless you

Either washer drain hose is too far down drain pipe, or there is a airtight seal where drain hose and house drain meet. Either would cause siphon effect.

you may have a pinhole in your drain hose

Drain valve not opening or pump impeller loose on shaft - is it washing ok?

My guess would be drain valve not opening. It is a 110v solenoid and they get stuck or burn up. New solenoid costs ~$20.00

The rinse water in a LX30 is driven by water pressure. A solenoid valve, bottom front - gold body, opens up and allows the water to flow.

If you are referring to the rinse agent pump, there must be NO leaks in the tubing or the hose that runs through the pump. And if the unit has lost its prime, using your hand to "seal" it, and forcing water from the faucet into the line can prime it.

Good luck - Mike
