Problems Really don`t know the exact model but the machine wash clothes normally but when finish don`t do anything to dump water nor to squeez.

I have this problem too. Called the repair man out to the house & he just told me it was set at the factory & there was nothing he could do. I discovered if I held the water level knob between the settings given, water would run to the level I wanted as long as I held it in place, but I don't know if this does any damage to the machine. So I don't know if you want to try that or if it can even be done on your model???

The code is caused by a water sensor. You can temporarily just dump about a half gallon of water into the tub before adding the clothes, and then have another half gallon for mid cycle. This stops the code from popping up. Try the half gallon thing and you will see.

I would try to run a few loads of towels with just water (no detergent or anything) to try and flush out any excess detergent residue you may have. I don't know if you are able to set your own water level on this machine, but if you are, I would just run an empty load or two.

Hope this helps...

I'm guessing you use fabric softer....Get some finish dishwashing powder and put a wash on with high water level with no cloths in it. let it do it's normal wash but before it drains any water out, pause the wash let it soak over night. next day unpause it and let it finish. Repeat if needed and do the same thing again with out any dishwashing powder in it to make sure it rinses all the soap out.
The black sludge is cause by using fabric softener. The costic in the finish powder will eat in to the sludge and soften it. If its really baked on it my need to soak for longer, more powder or it may need to be stripper and cleaned.

You may have already found a solution, but I had this exact same problem. I ran the tub clean cycle with bleach and then switched to a powder HE detergent. I found some other posts that said that liquid HE detergent has some thing in it that causes that smell and the tub build up (not sure what?). I was hesitant that that could really make a difference but it has. It has only been a week, but so far everything smells great. Definitely worth a try.

Check for a blockage in the water pump. If it does not drain first it does not spin. Check for power to the drain pump motor.If no pump blockage check the lid switch for continuity. No continuity, replace the lid switch.

You have a clogged drain pump or the hose between the tub and drain pump is clogged. There is a possibility that your model has a plastic cup inside of the pump inlet hose designed to keep objects and lint from getting to the pump. You can find this out by squeezing that hose and see if it feels hard. If that's the case you will need to remove the hose from the tub clamp side to pull the cup out and clean it out. Then the machine should function normally.

Most likely your water pump is blocked. I don't know where to find a parts brake down for this, as this model is not listed over here across the pond, but from the photo I found it appears that there may be an access door to a filter on the lower right side of the machine.

Check your drain pump, or drain line for obstructions. The number one cause of insufficient drainage in this model washer is debris building up inside the clean out trap on the drain pump. The following link explains how:

Make sure you check all the drain lines as well. Another common thing that can cause slow drain issues are small articles of clothing getting caught in the drain hose that is attached to the bottom of the wash tub to the inlet side of the pump. It has happened to me on occasion to find socks, underwear and wash cloths lodged in this area. You can usually squeeze the hose to determine if there is anything blocking it. NOTE: In some models, there is a ball valve in the upper most portion of this drain line where it attaches to the wash tub. This is supposed to be there.

If anything has been lodged in the pump impeller for significant periods of time, this can potentially cause damage to the impeller and/or motor. This will affect pump performance. If clearing the pump and verifying that there are no clogs does not fix your problem, more than likely you have a drain pump that is beginning to fail.

If you find that you need to replace the pump, a replacement can be ordered on line at searspartsdirect.com. Just type in your complete model number and look for item number 10 (part #8181684) under the "Pump and Motor Parts" heading. The next link explains how to replace the pump (if required):

I hope you find this information helpful. Let me know if you require additional assistance.

Check your exit hose spigot, it may be clogged. This is if your filter is all clean. There should be air for passage in the standpipe behind. Your hose should not fit airtight into the standpipe and neither too deep into it. Snaking out your standpipe would be good too.

And pl rate me if helped.................

if the machine works fine and runs through the programme without stopping, then never adjust anything on the machine to alter settings, this can cause more problems, computer control machines do the job very well under normal circumstances, the drum will hold sufficient water even if you can not see it for the clothes it holds, just to confirm this why not do a wash while no clothes so you will be reassured of the fact. i am a recently retired engineer of 20 years experience, and often have to reassure many people of this, don't worry of it works
