Dishwasher not draining problem with pump

Doe the pump make a sound as if it's trying to pump out? As it sounds as though your pump is either obstructed, or the outlet waste water pipe from back outside of the dishwasher to the drain, maybe bent somewhere or blocked & not allowing water to exit the dishwasher, if both are clear of blockages & no noise of the pump kicking in to empty the dishwasher then I would definitely say the pump has failed...

I hope this helps....

Is their debris in air gap or in the bottom of the DW, where the drain is screened?

1. The air gap is usually located on top of the sink. Lift off the pretty cover, and unscrew the top cap nut. Is there rice and debris there? Remove it then. Reassemble and check it out.
2. The DW drains to the bottom of the unit where the pump is. This area is screened off so that the pump doesn't get clogging debris in it. is their leaf lettuce and stuff covering this? Remove that debris. Some times this area can only be accessed by removing the bottom spinning spray head. It comes off with a nut, possibly this nut is reverse thread. Reassemble when done looking for debris.
3. Is the drain line between the DW pump (located under the DW) and the waste pipe kinked? This line is a plastic corrugated line about 7/8" around the outside. It is a pumped waste and won't work if it is kinked, so unkink it.
4. Is the float stuck. This is a device on the bottom of your DW that tells the DW how much water is in the bottom of the DW basin. It looks like a mushroom. Gently move it up and down. Does it move freely or is it stuck? Unstick it.

Good luck.



Is this a standard installation?

Hi
Dishwasher not draining issue usually occurs due to kinked drain pipe, clogged drain filter or drain pump. First make sure that the drain is not clogged and remove clogs if present. If no visible lint is present then remove the lower front access panel to check the drain filter and drain pump for any clogs, you'll need to clean the drain filter and drain pump completely. Also, check for any food pieces stuck near the pump impeller & clean the chopper assembly. Please note that dishwashers don't drain out the complete water such that heating element doesn't overheat. Hope this helps... Please post back for any further assistance.

Hi,

The drain filter is clearly visible at the bottom of the wash compartment but there are several possibilities as to why there is still water in the bottom of your washer:

1. Blocked drain filter
At the bottom of the wash compartment, there is a fine mesh grille and a plastic cylinder which protrudes from it. Grip the plastic cylinder, twist anti-clockwise and pull it upwards. To clean it, remove any debris from the cylinder, rinse then replace in reverse order of the above.

2. Blocked/kinked waste hose
Check the waste outflow hose at the back of the washer for any kinks or other damage. Also remove the hose where it attaches to your sink (or waste outlet) and check for any blockages.

3. Blocked waste disposal / sink trap / waste outflow
Make sure your sink is draining efficiently. Clean as necessary

4. Faulty waste pump
If all of the above check out, you may have a faulty pump. Please post back for further advice regarding this after completing the above checks.

Drain out is done via the pump out motor. Is the pump out motor working? Check by deternining with a AC voltmeter to see if supply voltage is across the terminals in pump out mode. If voltage is present and motor does not spin - the motor is open circuit and must be replaced. Remove the 2 clamps and the 2 electrical push on terminals with the MAINS voltage disconnected. Is the outlet pipe not blocked or obstructed ?

Do the following.

1. Switch off the machine, unplug or disconnect the mains AC power to the machine and turn off the water supply to the machine.
2. Remove the filter access panel.
3. Remove the filter and make sure that the filter is not blocked and is clean and clear of all debris. Clean as required. Note that depending on the machine type you may get a lot of water coming out of the filter when you remove it if the machine has not drained successfully. Note that if the machine has stopped and not fully drained then you may be able to drain out the excess water by removing or disconnecting the waste hose and laying it on the ground in a tray. It may take a few minutes to empty but it will save a small flood.
4. Proceed by checking the drain hose for proper connection and kinks and make sure that it is not blocked.
5. Also check that the main waste drain pipe, if you use one, is not blocked and clean if required.
6. Reconnect the power and switch the machine on.
If the problem persists then do the following.
7. Switch off the machine and disconnect the mains power.
8. Check the electrical connections at the pump and make sure it is operational.
9. Remove the connecting hoses, and expect water to drain out and make sure the pipes are not blocked with debris or any object blockage.
10. Makes sure the pump appears clear and that the impeller looks in good condition.
11. Reconnect the hoses and then reconnect power and switch the machine on.
12. If problem has not been corrected, then remove the pump and check that the drive coupling to the motor is OK and that the motor turns OK. If all is well then replace the pump.

4. Proceed by checking the drain hose for proper connection and kinks and make sure that it is not blocked or restricted.
5. Also check that the main waste drain pipe and one way valve to a sink waste connection if you use one, is not blocked and clean if required.
6. Access the pump from under the lower rotor arm and protective grille and check that the impeller is free to move and is not clogged or restricted by debris or sludge. Clean as required.
7. Reconnect the power and switch the machine on.

--probably food particles blocking impellor on pump--clear pump or drain hose is kinked or blocked where it enters pipe under sink .Always scrape plates clear of food particles before placing in dishwasher
