Question about Dishwashers

2 Answers

My SGS55M72AU/65 does not get rid of its drain water, although that wee pump in the bottom is clearly working (which I could see after removing filters and pump cover). There is no blockage near the drain pipe connection, so I infer there is a blockage somewhere inside the dishwasher, in a place I can't get to without further instruction. I've removed most of the drain water and pulled the unit out, so I could lay it on its side and start taking screws out. But I much prefer to have some guidance in what to do and what not. cheers, Albert

    OK, I understand from your reply that I need to focus on the solenoid valve upstream from the drainage pipe. Where is that valve located though, and how do I get to it ? If I am going to be successful in fixing this without a proper maintenance person, then it must be with clear instructions on which part to look for (you did that), where to find it in the unit, and how to get there for this particular make/model dishwasher.
    Could you please address the open questions ?
    ta, Albert

    Well it was helpful in giving some moral support: Without specific instructions from anybody, I knew I had a chance doing it like any other fool. Working my way back indeed was the solution. There was no solenoid valve as Sandy Gupta suggested, but a one-way flow flap that was blocked. My disconnecting some more, flushing with garden hose I cleared it all.
    Overall I am disappointed in the level of detail in instruction I got. But I bought into your service, and I got what I paid for, I can only conclude.

Ok i am attempting to help you although i dont see your make of dishwasher but im using what i know without manual. to ensure there is a blockage in the dishwasher remove that hose you checked at garbage disposal or vent and leave it disconnected and try to drain into a bucket. if it is not draining remove hose from dishwasher and ensure its clear. now where you removed the hose from on dishawsher look in there to see if clear and keep working back till you find it.

Hi, well look whethet your dish washer's drain valve solenoid is working or not. Sometimes it get broken due to which it not get rid of drain water. This can make it so the valve is always half open/closed. While draining, it would drain some, but also just **** air from the main compartment. While spraying it sprayed some, but some of the water was forced out the drain.

Get a new solenoid, replaced, and it will run fine.

Thanks! Sandy

    Also check for outlet may also be blocked which can cause the problem.

    And one more thins buddy

    The ONLY safe way
    to get by this issue is to install an air gap on the sink, for the
    drain that comes from the dishwasher. I know plumbers will swear that
    it is not necessary, but I never have that problem with an air gap
    installed, unlike anti-backflow valves, there are no moving parts or
    seals to go bad.

    Make sure you run the garbage disposal and run enough water through it
    to get rid of any debris left in it. Make sure the kids don't dump more
    stuff down it after you start the dishwasher and turn your back..

  • Sandeep Gupta Apr 23, 2009

    f the problem persists, it may be as a result of a slow drain. Try clearing the drain with a mechanical device. Chemicals are not very effective at clearing a slow drain because they flow through too quickly

I have an LG WFT635A top load washing machine it has stopped spinning and wont get rid of the water i think because i have been washing really dirty cloths it is blocked up in the bottom of the tub

It is a common fault that the drain fails to work in most machines in a period of time and is the most problematic fault in a washing machine. In all occasions it is important that your observation is most important and so is vital to the identification /rectification and solution. If you have noticed that water has leaked then as the drain hose pump/valve and fittings are located on the underside of the machine it is important that you look for possible leaks here. In some cases the drain hose would be clogged at the drain end to outlet of the house and so there will be back flushing resulting in overflow to the outside. Also the drain pump/valve can be clogged. Now remove the drain hose clamps and remove the drain pump/valve, clean the drain pump/valve, use back flushing to clear off all dirt. Now test using power to see if this works and can be simulated. When refitting, the hose must be tightened properly. If the pump/valve does not work even with power then it must be replaced. If there is intermittent power to the drain valve/pump then the program controller unit is a suspect.

Cleaning a pump:

Finally the washer must be placed with a tilt- use a spirit level- so that all water will drain to the outlet port and thereby there is no residual water remaining.

Kenmore front load washer is leaking water from soap

We had a similar problem with water coming out of the soap dispenser when the washer was run. I assumed that it was a problem with the water draining as everyone else posted here. I took off the front panel, got rid of the junk and drained it. Although this was great, it did not solve the original problem. It turns out that there was a sock stuck in between where the water comes out of the soap dispenser and in to the main compartment. Pulled it out with a needle nose plier and good to go. Thanks to everyone for their input here.

You seem to have a blockage,have you checked the filters lately.Also check the drain hose and the pipe that the drain hose goes into,if they are clear then the blockage is down in the bottom of the dishwasher in the pipes or the drain pump.

Ice builds up in bottom of freeze side by side

This is usually a plugged drain trough. Every time your refer defrosts itself, the melted frost drips off the evaporator behind the wall of your freezer and drains into a drain trough, through a hole and into a drain tube that ends above a condensate pan where the heat of the compressor-condensor evaporates the water. Food gets into this drain line and plugs up your line, causing it to freeze the melted water into a slab of ice that eventually drips onto your floor. Most units you have to remove the freezer back panel inside the freezer to get to this, although some models you can see the drain trough without removing the panel. You can use hot water to clear this. Flush it out until you hear water pouring into you condensate pan. I use a garden pump up sprayer to shoot pressurized hot water through the drain line to make sure it is cleared out. Needless to say dont use this if you have had any poisonous chemicals in your sprayer. Good Luck, Appliance Specialists

Standing water in bottom of dishwasher

The first thing to try is to clear out debris from strainer area, you may need a Philips head screw driver for this. Clear out and then attempt to put the unit through its cycle.

The second thing I would try, is unattach drain hose from drain to sink, either blow in it or use a blower side of shop vac to force air into the hose. Reset dishwasher, and try again.

Not knowing how handy you are, you can pull the dishwasher out, please turn off circuit before doing so, also make sure you have towels handy. Unattached drain hose at base of drainage pump. Clear out hose and remove debris on bottom of pump. Reattach the hose and run through cycle..

If these do not work your issue is with a bad pump.

Will not pump water out of the bottom of dishwasher

UNPLUG THE DISHWASHER. Inside the dishwasher is a covered drain, usually covered with a plastic guard to prevent large objects from getting into the drain. Remove the blades in the bottom (careful but on my GE they come off with a firm pull) Remove the drain cover and see if the drain is plugged. If it does not appear to be plugged, you may have a bad drain pump. This usually requires you to remove the dishwasher but on some you can access it by removing the bottom plate. You then can disconnect it from the dishwasher drain by loosening a band that holds it firmly to the pump housing. Be ready with something to catch the water as it drains out. If the water inside drains out then your pump is bad. Because the water inside drained out, that tells you that the drain to the pump is clear. Your dishwasher has a drain pump that moves the water out. You will need to remove it, check it for obstructions and replace it. If it still does not work, you will need a new pump. There are two water connections to the pump, one for the flow from the dishwasher and another for the flow out. There are two electrical connections that you will have to remove.

What is f21 on the kenmore he2

"F21" is a Long Drain error. This occurs when the drain time exceeds 8 minutes. You will need to remove the bottom panel under the door by removing the two screws at the bottom edge of the panel. First, check the electrical connections to the drain pump and make sure the pump is running. Check the drain pump filter to make sure it is not clogged with debris. This is a very common problem. HINT: Before removing the drain pump filter, pull the drain hoses from the standpipe at the wall and use a shop vac to pull a vacuum on the drain hose to get rid of all residual water from the pump and drain lines. This is also a good way to get rid of minor clogs. If you do not own a shop vac, be prepared to lay down some old towels and soak up some water. There's quite a bit of residual water in the wash tub and lines (this is normal). In addition, check your drain hoses to make sure they are not clogged or kinked. If you check everything and still have the error code, replace the drain pump. Replacement parts can be found at and Just type in your model number in the search menu. I hope this helps you.
