I have a customer that needs some parts. They need a wash arm mount/filter screen (just the screen really).
The dishwasher is taking in water but the metal filter is so built up with years and years of debris that the pump isn't pumping water. He came in with the complaint that the dishwasher isn't spraying the soap out of the detergent cups. I dumped a gallon of vinegar and some hot water in the unit to let it sit over night just to see if any change happened. It grumbled and groaned but it took more water out than last time. I took the wash arm off to see if the support was solid and discovered the torn mesh filter. I am thinking I would probably dump some CLR in it and let that sit. Everything is so built up that I can't get the filters off to scrub them. Also, if I can get it going for him, I am going to have the service department replace the drain hose and the water line. The customer said that he didn't realize the dishwasher needed to be cleaned out from time to time and it has been in constant use since when the house was built many years ago. Anyways, if anyone could help him out, I would appreciate it. The kitchen is laid out in such a way that the dishwasher door just barely clears the fridge when it is opened. I know the door on a tall tub would hit the fridge. Also, this is different than my KDS18/58's that I have, how do you take the metal filter off? Just pull straight up with the bakelite on top or? I am so afraid of breaking something because of the build-up. |

Hi there is only one filter that needs occasional cleaning on this DW, after you lift the WA off you just grab the top edge of it and pull upward to remove it.
Replacing the fill and drain lines will do nothing to help this DW work better, it probably could use a new inlet valve and a new drain check valve, and in the future it would help if the user used better detergent, maybe softer water, and differently stopped rinsing the dishes before loading.

Is it safe to run with that top filter in the condition it is in?
The water line is an old copper line that has a slight kink in it. I have noticed around here copper lines tend to have a lot of buildup the older they are. I will go back over probably tomorrow and pull the stainless filter out and clean it for him. Thank you for the reply. I'll take some boil out with me. |

The DW may not have enough water in it [ try the same test with an additional gallon of water added ] If this works REPLACE the inlet valve or if can find them replace the rubber diaphragm in the valve.
You may have a bad drain line check valve [ check for a sucking at the end of the drain hose while DW is washing, if you hear or detect one the rubber in the CV is bad ] replace rubber with GE part.

So my customer decided to go with a stainless Miele classic. He said his kids told him up upgrade.
I have been holding on to this thing cause i don't wanna see it get tossed. I put it on the lift to lay it on its back. Here are pics of what I'm seeing. Any thoughts? |

Oh and the check valve was plugged by the flap, so thank you for that. The tech here said naw. Lol.

Ok, I played with the drain hose, when I stopped the hose with my hand the spray took off like crazy. So I tore apart a GE check valve I had on the shelf and put the flapper in there. I ordered a replacement flapper.
When I was playing with the hose, letting pressure in stopping pressure etc, it must have broke something loose because all of a sudden it started draining the entire sump like it was supposed to. Now I am trying to get all of the hard water build up out... I scrubbed the sump and most of the tub with barkeepers friend... rinsed the machine about 8 times to finally get all of that out, now I am running a pots/pan soak/scrub cycle with Miele's dishwasher conditioner tub in there. It is odd there is only one rinse on the wash cycles.. I mean I guess one would have two rinses if they didn't use the second rinse cup? Eh, lol IDK. Anyways, I appreciate all of the help so far. |

I've got a slight leak on the drain connection from the sump and from the middle wash arm feed outlet on the sump.
I wish there was a video on taking the pump housing apart, its amazing what youtube has brought for people wanting to do DIY repairs. I'm just hesitant because I don't have replacement gaskets. I had ordered a new detergent dispenser assembly and two bi-metals for my KDS58 that I have. I went to put that together since I was in such a nostalgic mood and I can't find my screws. Was going to steal the screws from my KDP58 that I have and found out those are all rusted out. I am going go to Menards tomorrow after work and see if I can find some stainless screws that are similar in thread and size. |

When I came in this morning to take the DW off the bench for the week there was water every where. The bottom of the motor had water sitting in the cover and the work surface had enough standing water that it saturated a heavy dish towel. I am not sure what seeped where, but when I left, I had turned off all of the water and disconnected the power. No one was here until I got here this morning. The motor and work surface were both dry except for the two small leaks I mentioned earlier. After the last cycle I ran, I looked in the sump and it looked like it had drained properly. The drain hose was full like you would think it would be so it didn't come back through the check valve.
So when I take the pump out, I'll have to check everything. |

I ran 2 rinse/hold cycles and then a cancel cycle when I was rinsing the tub cleaner stuff out of the unit. When I checked everything before I left I looked in and saw that the water had drained out and it didn't look like water was sitting in the sump.
I turned the water valve off on the wall, unplugged the dw and propped the door open with a towel. I checked underneath to make sure it was dry, there was nothing there. I shut off the lights and left, that was at 4 am Sunday morning. I came back at 8 this morning to that. As far as what was in the house, the tech didn't say if there was a bunch of water on the floor, but I had been over there earlier trying to run a bunch of vinegar and hot water through it. If the sub floor had been wet, He would have told me. So I don't imagine that it was leaking when it was in the house. I did attempt to take the fine mesh filter out before I put the new drain flapper in. I took the 4 screws around the wash arm support off, the 8 or so on the outer edge of the fine mesh filter and the four just below the filter assembly where the knockouts were. I couldn't get anything to budge, I tried to see if I could shift anything with a flat blade screwdriver, nothing budged but I didn't put a lot of pressure on anything so I put all the screws back in. That was around midnight. So the dishwasher had been running for at least 4 hours without anything more than a slight drip every so often. |
