Nine times out of ten, a clogged filter or blocked spray arm nozzles are the culprits. Start by deep cleaning the mesh filters at the bottom of the tub and using a toothpick to clear any debris from the spray arm holes.
Ignore this long enough and you're not just dealing with dirty dishes. You're burning out the circulation pump because it's fighting a clog it can't clear. I've seen that turn a $15 cleaning job into a $250 pump replacement. Most of the time you're 20 minutes away from fixing this yourself. Sometimes it's a failed part, but honestly that's the minority of calls I go on.
OK so here's what I find on most of these calls. The filter hasn't been touched in a year, or the spray arms are completely caked with hard water deposits. Costs nothing to fix if that's the issue. The thing that actually surprises homeowners is when I tell them their water heater is set too low. Below 120°F and your detergent just won't dissolve right. Your dishes end up getting rinsed in warm, mildly soapy water and that's about it.

Symptoms You May Notice
Dishes come out with visible food bits still stuck on them, especially on the bottom rack right near where the spray arm rotates.
There's a cloudy white film or greasy residue on glasses and plates after a full hot cycle, like they went through the dishwasher and came out worse.
The top rack dishes look completely untouched, like they sat in a steam room but never got washed, while the bottom rack is mostly fine.
You can hear the pump running but there's no splashing sound during the wash, just a low hum or growl, which means it's cavitating and not actually moving water.
The detergent pod or tablet is still sitting in the dispenser at the end of the cycle, whole or only half dissolved.
Can you reset a Electrolux dishwasher to clear the CLEAN-FAIL code?
There's no fault code to clear here, but to reset any stored errors and start fresh, press and hold the Start/Cancel button for 3 full seconds until the display goes dark. Then turn the unit off at the circuit breaker for 5 minutes. Power it back on, pick a hot Normal or Heavy cycle, and run it empty with a dishwasher cleaner tablet to see if wash performance comes back.

Frequently Asked Questions
Why is there a white film on my dishes after the cycle?
Almost always hard water deposits or too much detergent. First thing I'd check is your rinse aid dispenser. If it's empty, that's probably the whole story right there. Refill it and run a cycle. If the film's already built up on the tub walls and spray arms, grab a bottle of citric acid descaler or just run an empty cycle with a cup of white vinegar on the bottom rack, no detergent. If it keeps coming back every few weeks, you've got hard water and you need to either use a water softener or at least stay consistent with the rinse aid.
How often should I clean my Electrolux dishwasher filters?
If you're running it daily, rinse the fine mesh filter once a month minimum. Running it a couple times a week? Every 6 to 8 weeks is fine. But if you're doing a lot of greasy cooking or not scraping plates well before loading, do it more often. I pulled a filter out of a machine last week that hadn't been touched in at least 3 years. The pump motor was already starting to overheat because it was working twice as hard to pull water through all that debris. That's a $200+ repair that a 2-minute rinse would've prevented.
Can I use vinegar to fix my dishwasher not cleaning?
Vinegar's great for mineral scale and that's basically it. Run a hot empty cycle with a bowl of white vinegar on the top rack and it'll knock out a good amount of the calcium buildup you can't reach directly. But if your filter's packed with food or a spray arm jet is physically blocked, vinegar isn't touching that. Use it as a maintenance trick after you've done the real mechanical cleaning. And check your manual first because some manufacturers say regular vinegar use can degrade the rubber door gasket over time.
What detergent works best for Electrolux dishwashers?
Pods or tablets from a name brand. Finish Quantum or Cascade Platinum are what I actually tell my customers to buy. Cheap generic pouches don't dissolve well in shorter or cooler cycles. Avoid liquid gel entirely in these machines, it creates too much foam and the sensors get confused about what's happening inside the tub. And don't think more detergent means cleaner dishes. It doesn't. You'll just end up with residue and filmy buildup on your glasses. One pod per load. That's it.
Why is the top rack not getting clean but the bottom is?
Nine times out of ten it's that upper spray arm manifold docking port on the rear wall of the tub. There's a port back there that the middle spray arm has to click into firmly. If the bottom rack isn't pushed all the way back when you run a cycle, or if the rubber gasket on that dock is dried out and cracked, you're losing all your water pressure before it even reaches the top rack. Pull the bottom rack out, look at the back wall, and check that port. The gasket is usually only a few bucks. Also make sure the spray arm itself isn't cracked anywhere, because a crack drops pressure just as fast as a plugged jet.
