How Buying OEM Parts Can Save You Time and Money
We're sorry, but our Q&A experts are temporarily unavailable.
Please check back later if you still haven't found the answer you need.
1a) Unscrewed lower spray arm cap. Removed lower spray arm. Removed metal radiant shields from lower spray arm, cleaned them, and snapped them onto the new lower spray arm.
1b) Removed Torx screws from pump cover, then removed pump cover.
1c) Curled new filter into circular shape, interlocking the tabs to connect the ends together, then replaced the old pump housing filter by removing the old filter and then pushing the new one into place in the pump cover. Old O-ring was fine, so didn't really need to replace it.
1d) Re-installed pump cover by aligning the water ports on the cover with those in the dishwasher, then pushing cover down into place, then installing and tightening the Torx screws. If I were to do this repair again, I would replace the pump cover with a new one.
1e) Installed the spray arm by placing the new lower spray arm into position over pump cover, then screwing in the lower spray arm cap.
2) Upper Spray Arm
2a) Removed upper spray arm by unscrewing the snap outlet nut, then removing the spray arm retainer. This way, the retainer is undamaged and can be re-used.
2b) Attached new upper spray arm to snap outlet nut by pushing old retainer through new upper spray arm and into snap outlet nut.
2c) Installed new upper spray arm by screwing snap outlet nut back into the dishwasher.
To fix the leak in the door it is necessary to replace the bottom spray arm. This is because when the lower spary arm fails it gets small splits which, when spraying, send water up into the door vent and inside the door. It then leaks out the bottom of the door to drain.
1. Take out he bottom dish rack.
2. Locate plastic nut (lower spray arm cap) on lower spray arm (see parts diagram).
3. Remove plastic nut (lower spray arm cap) by hand - it twists counter clockwise to loosen.
4. There will be a small piece (jump-up nozzle) under the plastic nut (lower spary arm cap). Note how it was situated. Place it aside with the lower spary arm cap - you'll need them both during reassembly.
5. Pull off lower spary arm and filter guard (they are attached to each other).
6. Note how the lower spray arm was attached to the filter guard. The top and bottom of the lower spray arm are not the same.
7. Unsnap lower spray arm from filter guard by pulling up on one side and then the other to removed it from the plastic clips on the filter guard.
8. Install the new lower spray arm, by snaping it into the plastic retainers on the filter guard, one side at a time. Make sure you installed it with the correct side up.
9. Remove the two metal pieces (Radient Shield)from each end of the old lower spray arm and place the on the new lower spray arm. A small flat head screwdriver is useful to assist in removing them from the old arm.
9. Place the assembly (lower spray arm and filter guard) back onto the dishwasher and place the jump-up nozzle back into position.
8. Attach the palstic nut (lower spray arm cap) and tighten clockwise until secure. Don't over tighten.
9. Slide the bottom dish rack back into position.
This will fix the problem of the leaky door. I went ahead and replaced the upeer spray arm at the same time since it was a connvient time to do so.
If you wish to do so read on.
Replacing upper spray arm.
1. Remove the bottom dish rack.
2. You can remove the top dish rack, but you don't need to.
3. Examine where the upper spray arm is attached to the dishwasher. You will see three parts. The one on the spary arm center - toward the inside of the dishwasher is the SNAP SPRAY RETAINER. Next is the UPPER SPRAY ARM itself. Next, between the UPPERT SPRAY ARM and the body of the dishwasher is the SNAP OUTLET NUT.
4. Remove the SNAP OUTLET NUT by turing it counter clockwise (remember its upside down so you have to be looking up at it to determine which way is counter clockwise). I had to use a screwdriver blade and the palm of my hand to get it to loosen - I set the blade against one of the Knurls on the nut and gave it a tap with the palm of my hand).
5. The whole assembly will drop down. Remove it from the dishwasher. Note the way the UPPER SPRAY ARM is positioned; as the two sides are different.
6. With a pair of needle nose pliers compress the wings of the SNAP SPRAY RETAINER and remove it from the assembly. The assembly is now in three pieces.
7. Replace the old UPPER SPRAY ARM with the new one - again make sure it is in correctrly, as there is a top and bottom to the spary arm.
8. Insert the the SNAP SPRAY RETAINER into the new UPPER SPRAY ARM and into the SNAP OUTLET NUT. Place the assembly back into the dishwasher by tightening down the SNAP OUTLET NUT - turning it clockwise to tighten.
9. Replace the uppper dish rack if you removed it.
10. Repalce the lower dish rack.
Discharge Housing Assembly (#11)
Impeller Assembly (Wash Impeller) (#14)
Upper Discharge Housing Gasket (#38)
Removed upper and lower washing baskets.
Pulled off Upper Spray Arm (#33). It pulls off easily by hand. No tools required. Replaced with new Upper Spray Arm (#33) and Snap Spray Retainer (#31).
Removed Large Spray Arm Cap(#34,)which has a right hand thread. This allowed me to take the Lower Spray Arm(#2)off.
Removed Filter Guard (#36).
Next I removed the 6 screws from the Pump Cover & Secondary Filter Assembly (#4) with a Torx screwdriver. Removed Lower Spray Arm Seal(#3), Pump House Filter (#6)(which I cleaned), Assembly, Rinse Arm (#7) Jump Up Nozzle (#1). Unscrewed Discharge Housing Nut(#8) by hand. Removed Support, Wash Arm (#9). This allowed me to remove the three screws holding the Discharge Housing Assembly(#11)with a 5/16th nut driver. Next I removed the Impeller Screw (#12) with a 5/16th nut driver. You must hold the Impeller Assembly (#14) firmly while loosening the nut. Removed Impeller Assembly (#12) and Plate, Suction (#15). Cleaned out area of debris,lint, etc. Put back old Plate, Suction (#15) and replaced Impeller Assembly (#14) with new part. Replaced Upper Housing Gasket and Discharge Housing Assembly with new parts. Put back all parts in the reverse order I removed them replacing the O-Ring (#37) with a new part. This O-Ring goes in the Pump Cover & Secondary Filter Assembly (#4).
After completely assembled it ran as good as new!
The upper spray arm comes off by gently pulling down on the spray arm. I put the new one in its place.
The lower spray arm had a thin, large (about 2" diameter) round screw holding it and its housing in place. I removed the large, flat screw and the lower arm came off. Below that was the filter housing. I unscrewed the six screws, took off the housing, replaced the filter, and put the housing back on.
Then I removed the lower arm from the plastic thing that was holding it, removed the stainless steel heat plates and put them on the new washer arm. Put the washer arm back on the thing that held it, and screwed the washer arm assembly in place with the large plastic screw.
