Disconnect the dishwasher power supply and water connector.Then disconnect the drain hose.Take off the hose from the pump and on the plastic valve is the black valve flapper.Mine was swollen twice the size of the new one.Replace with the new one.You have to pull the dishwasher out and turn it over to do this.The check valve was totally worn out.You must turn the dishwasher back to it's in use position and open up the door.Inside the lower rear wall is a plastic cover with 4 screws remove these and the cover.Then unscrew the piston and nut assembly and remove the check valve.Simply replace with the new parts and reinstall the cover.I replaced the gasket before I reinstalled the check valve even though it looked ok.To do this you need to turn the dishwasher over again and remove the 4 screws dolding the resevoir the check vave is in.Replace the old gasket with the new one and reinstall the new gasket.Do this after removing the old check valve and before intalling the new one.On the bottom inside the dishwasher I noticed the large white gasket on the floor was falling apart so I replaced that also.I'm glad I did because below this assembly there is a reusable plastic filter that was totally plugged that I cleaned and reinstalled before relacing the filter gasket assembly.To do this you must remove the plastic water jet.With a screw driver there are 2 plastic tabs that must be carefully pulled out so you can pull out the water jet.Remove the 2 screws and plastic cover on top off the gasket assembly.Retain the 2 screws but you will not need the cover it is part of the new gasket assembly.There are two clips you need to carefully pry off.Then lift out the old gasket assembly and replace with the new one.Reinstall the 2 screws that held the old cover before and If reinstall the old clips if not damaged.You can purchase new ones but usually not needed.Then gently snap the water jet in place.Put the dishwasher back under the counter and reconnect the power,water line and drain hose.
No Plumer could help me. No one heard of a dishwasher check valve. My dishwasher was an ISA. I was lost until i found the relationship to Kitchenaid. Then sears. Vuela!The valve was there, but unavailable.A few more links, and the term "flapper" came up.Well, my dishwasher check valve HAD a flapper inside. Although a plastic pos, i could unscrew the two halves and see the flapper. A little piece of rubber, about 1" in diameterAll suppliers gave me but two choices. One large (size given) one smaller. After years of searching, all I needed was a flapper valve. Not the whole check valve.I found it hear for under $10
Changed check valve and valve flapper. Had to pull dishwasher out of cabinet to get to the backside. Removed check valve and replaced valve from inside dishwasher ( all the way at the back, large nut holds in)but had to remove lower assembly from rear in order to change out the gasket. Removed large black flexible tube and replaced flapper valve. Just be carefull sliding hose back over section containing flapper valve. Fairly easy switch out. Took care of problem.
I unscrewed the check valve, tipped the dishwasher on its face, and removed the asembly below it. Then replaced the valve flapper, cleaned out the assembly (broken champagne glass and udder nasties) then put it back the way I found it.Then I put the new check valve on, and started the dishwasher up. 10 screws and $30 worth of parts saved me 400 bones for buying a new dishwasher.If you have sanding water in your dishwasher check these two parts.....that check valve is the culpret.
First I replaced the flapper valve of of off the water pump. That worked for a couple of days, then the standing water was back. After more research at your site I ran across other person who had the same problem and they ended up replacing the piston and valve assembly. After pulling the dishwasher out I was able to find where these parts were located. The piston's rubber part was half gone. I replaced it and the gasket and another flapper valve. This model has two flapper valves. One difficulty was that you have to replace the screen inside the dishwasher before you replace the housing that the piston fits in. Your site and other folks contributing their stories helphed me to solve our problem. The dishwasher works like new now. Thanks. Ralph Naddeo.
Easy. I removed the dishwasher and all water from inside. After laying the dishwasher on floor, the valve flapper was installed using a pair of pliers. I then set the unit upright, and removed the rear screen from the inside back of the unit. This part has 4 nut screws, and runs the width of the unit. Under the screen, the Piston and Nut Assembly for Check Value simply unscrewed. When I looked at it, I knew this would do the trick. I simply screwed the new one in, and re-installed the dishwasher. After the first cycle, I smiled thinking of all the $$$ I saved.Parts Select is great :)
Removed the dishwasher from the cabinet. Turned it on it's top side. Removed the exit hose from the pump with a nut driver and replaced the flapper. Reconnected the hose to the pump.
First, I drained the water from inside the washer and removed it from under the sink. I wasn't sure if I had a clog in the drain line, so I dissasembled the drain under the sink and cleaned that as well. While cleaning under the sink my wife found her $4000 dollar ruby that fell out of her mothers ring a couple weeks earlier. It must have dripped out of the trap while I had water draining everywhere. Put drain back together and moved on to the dishwasher repair. Parts were easy to install after laying the dishwasher down on its front to access the bottom back side. Hooked everything back up and slid it back under the countertop and away it went. Had one small leak after running (water in line wasn't tight enough). A twist with a pair of pliers and that was resolved. Fast shipping by the way! I paid a little more for the exit washer than I wanted to, but with shipping only from one source and delivery of parts at the same time made downtime as little as possible. I'm sure I saved $100 dollars or so by using this website for parts and tech info. And recovered a precious stone to boot.
I tried to take it apart, clean it an put it back together. In the process I found the valve flapper to be old and in need of replacement and the lower spray arm assembl tabs broke and required replacement of the entire assembly when I only needed the bottom half. I cleaned all hose/wet connections, coated with plumbers grease and put back together. No leaks, drains properly. Took a bit more time than expected due to door within pump housing that was removed for cleaning that didn't want to be put back on.
I could not have accomplished this repair without this site. It lead me not only to the problem but what parts would be needed. Since the pump worked okay I decided the water must be draining back from the hose since the bottom of the washer was lower than the discharge point of the drain hose. I thought there must be a check valve someplace. When I found PartSelect it was easy to go to the brand of dishwasher, model number, symptom and lots of advice from people with the same repair in the past. I decided to go with the piston and nut assemble (check valve) and the valve flapper. On the web site there was a blowup diagram that showed where the part was and advice on how to properly install the parts. When I looked at the old check valve and the new one you could easily see that was the problem. Replacing the flapper was added insurance.
Called repairman: announced that the drain pump was gone. Did not seem right. Went to the website. Found what I was looking for. 49% of the time it was a check-valve issue; only 26% of the time was the pump the problem. Took the unit from under the counter; got it on its side; removed the drain pump. Found my first check-valve, but thediagram showed a second lower one toward the sump. Having located both and purchased two valves and and the lower holder piece, I was ready to finish the job. Quarter-inch nut driver and a screw driver and the valves were in and the drain pump re-installed. Most difficult in my case was getting the dw back into its spot and lashed down! Thanks for the good guidance!
Thought it might be check flapper valve on drain pump, so I replaced fairly easily, per instructions. When doing, I noticed the attached relay wires were not secure. When it was on the drain cycle one of the relay wires vibrated badly and loosened the connection enough to only work occasionaly. Would like to put new relay on the pump but they do not sell separately from the pump. (one assembly). I resecured connection and will wait till relay gives out and buy new assembly, but for now it's working perfectly!
Removed the dishwasher to get at the defective parts and removed,than replaced the two check valves and reassemble.
