The strip comes right out when you pull, there is a space to grip it on the left and pull it out. The notch goes on the right side when you put it back in; it only goes in one way. I didn't get it all the way in the first time and closed the door; the gasket came right out. A clear sign that I had done something wrong! So I put it in again, this time pushing it as far as it would go. It went all the way in and stayed. It doesn't click or anything, but you can kind of feel when the notches all connect. Also, it doesn't slide right out again.... very easy!

First, I had to remove a small metal paper clip that somehow ended up in the bottom of the dishwasher, which jammed the spray arm. The spray arm wasn't able to spin around, so it melted onto the heater. I removed the spray arm, and replaced it with the new one.

Door latch was broken

It was easy to replace the latch. 4 screws to take the cover off... two star screws for the latch assy. and 4 wires. NOTE: be sure to kill the power to the washer

Water in dishwasher did not heat up. Dishes came out dirty and greasy. Some fungus started to grow in dishwasher.

Unplugged the dishwasher. Closed and disconnected the water supply. Removed two screws that attached the dishwasher to the countertop. Pulled the dishwasher out from underneath the countertop. Laid the dishwasher on its side to access the bottom. The high limit thermostat had shorted out and showed signs of electrical burn. I removed the high limit thermostat by unscrewing the single screw that holds it in place. I then pulled the two electrical terminals off the high limit thermostat . One terminal (i.e. small electrical plug connecting electrical wire to high limit thermostat) was burned badly. I cut it off the wire and attached a generic terminal bought at local hardware store (six for $3). The other terminal was fine. I plugged the new high limit thermostat in and attached it with the single screw to the dish washer. Put the dishwasher back in place. Test ran dish washer and dishes came out shiny, clean and dry. Done.

Door would drop when opened....no tension on springs

First unplug the unit.

Second remove the kickplate. When you do this pay attention to the position of the insulation panel. It is confusing as to how it is put back together. Simple if you see how it comes apart.

Third unsrew the screws that hold dishwasher in palce under the counter top.

Genly pull the appliance from under the counter top. Understand the copper piping connected to the unit for water will only allow you to pull it out a few inches. Otherwise you would have to turn off and disconnect the water supply.

Reinstall the plastic clipsand springs. There are several holes in the frame of the dishwasher where the springs will attach. The further back you attach them, the more tension will be applied to the springs. This part of the operation is somewhat trying as you have limited visibility and access.

When springs and clips are installed, test door, slide unit back in place, reattach kickplate and insulation panel and then reattach to countertop.

All in all relatively simple and doable. If I had any problem it wasnot paying attention to how the insulation panel and kickplate came apart. No big deal.

Dishwasher racks were chipped and starting to corrode.

First I just rolled out the lower rack assembly, and rolled the new one in. Then I moved onto the upper rack. I started by sliding the off the rail cap lock at the end of the rack. The entire cap does not come off, just the bottom slotted piece. This is done by simply edging out the bottom of the cap, toward the front of the dishwasher, until the bottom slides out of the slot, and lifts out of the way. Then the upper rack was released to roll freely out of the support rail. The next step was to pry off the top of the water diverter. Next was to unscrew the wand assembly from the water diverter that is attached to the upper rack assembly. There are no water lines attached to this, it just directs the jetted water from the top of the dishwasher. Then simply pop the mount from the upper rack. And reassemble the way it came off. This was a simple fix to make the dishwasher like new inside again. The racks purchased from Parts Select fit perfectly with no modifications or trouble. This operation took less than ten minutes. Anyone should be able to handle this operation. If you are afraid to disassemble the upper rack, take a few digital pictures to refer to, and delete them later. This is a tip that has been priceless to me in the past on other projects. Thank you Parts Select.

The dishwasher would not spray to middle or top rack and detergent would not dissolve.

I pulled off the cover inside the sump area. Then pulled the washer out from the counter and turned it on it's side. I took the old pump out and crimped a new wire harness on. It was a simple repair for a DIYer.

Before pushing the dishwasher back, I tested the dishwasher with it pulled out from the counter. It was easy to see water was flowing forcefully through the upper tubing now. Success.

Troubleshooting this faulty pump was harder because it was functioning, but it did not have enough force to push the water up to the top rack. I convinced myself that the pump was the problem by plugging the lower rack with a cork. The spray was still too weak to rotate the upper spray arm. I also ruled out the timer with a stop watch. This unit alternates upper and lower racks by pausing either 0.6 seconds or 3 seconds. This controlls a ball that diverts water to the upper or lower rack.

Unplugged dishwasher, pulled it out. Unclamped hose and unscrewed water source to inlet valve, removed wiring harness, unscrewed bracket and reinstalled new valve. Now have a functioning dishwasher.

high limit thermostat was open

Disconnected power to the unit at the circuit breaker. Removed the bottom panel of the dishwasher. Used a stubby Phillip screwdriver to remove the single retaining screw holding the high limit thermostat against the bottom of the dishwasher tub. Not only was the thermostat burned out, one of it's electrical connectors was also destroyed. Removed the tape holding the cable bundle together so that I could work on the quick disconnect plug outside of the unit. One end of the quick disconnect plug was completely burned through and needed to be replaced. After doing the necessary electrical repairs and assembling the new thermostat into position I applied power and everything worked fine. It helped having a picture on your website that I could use to identify the correct replacement part.

Dishwasher leaking

Thought the problem was a faulty door gasket (there was a gap in the middle of it) so I ordered new(new one had a gap also) replaced it anyway - maybe it was worn out? Still leaked! Had to sit and stare at it and cycle it through. finally realized the spray arm had a hole in the end that was spraying directly into the gap in the door gasket. Hot glued the hole and it stopped so I bought a new spray arm - no leaky!

Leaking from the bottom of the door

With the door wide open and lower dishtray out, I pulled the old gasket out of its channel. I cleaned the channel with a rag and replaced it with the new gasket. It needed to be trimmed about an inch in order to get the door to close properly. Took me about 5 minutes. Then I removed the old bottom door gasket. Just grasped the plastic edge showing while the door is completely open. Pull outward with fingers moving toward the heating element. Cleaned this area also. Took the new gasket with notch on the right hand side of the dishwasher and pushed it into place. If you get down and look closely, you can see where the notch hooks up. The rest of the piece just slides in after that. Hasn't leaked since! No leaks AND no service call fee. Parts came super fast! So glad I found this website. I'm a housewife, you can do this!

Lower spray arm heat shield melted

Electrolux part number PS1524955, lower spray arm.

Problem. Dishwasher was spraying water out the bottom of the door. The spray arm was damaged when the heat shield overheated, causing the shield to contact the heating element. This resulted in the spray arm melting, causing water to be sprayed out the small gap between the dishwasher door, and the dishwasher bottom pan.

Repair
Lower spray arm is easy to remove. Release the arm clips at the center of the spray arm. When the clips are released, lift and remove damaged arm. Replacement arm is attached by pressing down on the center of the spray arm. The new unit has smaller heat shields so it will be less prone to overheating.

Thanks for the fast shipping. Part was recieved in a few days. For just a few dollars, the handwashing is over.

Heater High-Limit Thermostat Failed

  • Customer: Scott from Hermitage TN
  • Difficulty: Really easy
  • Time to Complete: 30 - 60 mins
  • Tools Required: Screw drivers
  • 14 of 15 people found this instruction helpful
As another poster had written, on terminal on the thermostat was burned off, most likely due to poor contact by the female spade connector on the end of one of the wires. Removed the DW, tipped it back to gain access, removed the failed thermostat, installed the new one, crimped a new terminal on the end of the wire, and re-installed the DW. Tested all cycles with the heat on and everything worked as designed. Very simple repair, took more time to get the DW out and put it back in than to replace the part and repair the wire.

Frigidaire dishwasher main pump failed

10 year old stainless steel faced Frigidaire dishwasher. The motor assembly part fixed my problem. This was the second part required to fix the dishwasher. A week prior I replaced the inlet water solenoid switch to correct the "no water filling issue". I think that the main motor assembly pump ran dry and caused it to fail, so it is critical NEVER to run this part dry. The repair was relatively easy, I will say it would be great to have some instructions with the parts, however the kit came with everything. you essentially slide the dishwasher out disconnecting power and water ( i left the discharge connected since the service loop was long). you disconnect all the main pump electrical and water connections, labeling made it easy. you take the motor assembly out thru the inside tub. Once the internal sump assembly is out you can clean the sump and remove the old pump. Pull it out straight and dont wiggle it. The kit comes with new O rings that i put a light smear of vaseline on for a good seal. You reinstall the sump and make connections. Since my dishwasher is old, the original Molex power connector to the motor is different on the new motor. The kit comes with a new style connector, what you have to do is snip off your old connector and the kit comes with a new connector with crimps on the ends, you slide the provided heat shrink over each wire and then crimp your dishwashers wires to the new connector. I then used a butane lighter to shrink the heat shrink. The heat shrink is not absolutely necessary since the crimps are insulated, but since the kit came with two perfectly cut pieces of heat shrink I felt obligated to use it. This sounds all complicated but it really wasn't and much cheaper than a new dishwasher! Interestingly and this only maybe in my case but the dishwasher seems to clean better than it ever did.. for now we are not pre-rinsing!

Drain hose was missing

My friend bought a used dishwasher at a garage sale, the previous owner had thrown away the drain hose because it was "nasty" they said....remember it could have been cleaned. When I went to install it, I removed the old washer, and discovered that the old hose would not fit on the replacement dishwasher. I went to the local repair shop, armed with the model and serial #'s. they searched and searched their books and could not find the hose part number. they said "good luck" when I left...I went home and looked up the model on your web site, ordered the hose, and in 3 days had the dishwasher installed and running in about 30 minutes...thanks for prompt shipping.. I couldn't believe it arrived so soon...Mowerman
