The error message is an indication of drainage problem, which indicates your dishwasher isn’t draining water as it is supposed to. Whether it’s because of clogged filter, broken pump, or clogged hose, the issue can interrupt your kitchen routine.
Luckily, you can fix it yourself if you can. In this 2000-word article, we will delve deep into what Error 20 is, why it happens, and how to fix it step by step. From the best sources, we will provide you with a clear picture of this prevalent issue.
What Does Error 20 Mean?
Electrolux dishwasher Error 20 is an indication that the drainage system has malfunctioned. According to various sources, including Electrolux’s own troubleshooting pages and consumer forums, the error appears when the dishwasher fails to drain water within a certain time limit usually one minute.
On those that lack a digital display, you might notice the “.”. This self-test feature is one of Electrolux’s latest designs, which informs you of a specific failure so that you can repair it in time.
The blocked drain may be due to one of several culprits: blocked filter, blocked drain hose, faulty pump, or faulty pressure switch. Knowing the cause is the start of getting your dishwasher working again.
Typical Electrolux Dishwasher Error i20 Causes
Let us categorize the most usual reasons for Error 20 by categories based on professional opinions and user feedback on hand anywhere online:
Blocked Drain Filter
Bottom drain filter of the dishwasher collects food particles and debris. Over time, it clogs with grease, food, or small items like pieces of glass. Blockage of the filter clogs water draining, leading to Error 20. It is one of the most common solutions reported by users as the simplest and easiest solution.
Blocked or Kinked Drain Hose
The drain hose carries wastewater from the dishwasher into your sink drain system. Water is blocked and causes the error if it’s bent, kinked, or plugged with gunk. Installation issues, such as an overly long hose (more than 400 cm) or installed incorrectly, may also trigger it.
Malfunctioning Drain Pump
The drain pump is the heart of the drain mechanism, pushing water out of the machine. When clogged with debris (e.g., hair or food particles) or mechanically malfunctioning, the dishwasher fails to drain, and Error 20 results. Pump running continuously may also be caused by a faulty sensor.
Faulty Pressure Switch
The pressure switch also monitors water levels in the dishwasher. Stuck or faulty, it will show water still present when the machine is empty. This false reading will keep the pump running and cause the error to show.
System Glitch
Other times, Error 20 is a control board glitch that corrects itself temporarily. A reset will be all it needs, but repeated errors suggest a larger issue.
Step-by-Step Troubleshooting Guide
Ready to fix Error 20? Employ this step-by-step guide, taken from the top online sources, to diagnose and fix the problem:
Step 1: Reset the Dishwasher
Prior to fixing, attempt to reset the machine. Unplug it or turn off the circuit breaker for 3-15 minutes. This could clear small electronic issues. Plug it in once more, choose a cycle, and observe whether the error remains. If yes, proceed with physical checks.
Step 2: Inspect the Drain Filter
Draw out your dishwasher’s dishwasher and pull out the bottom basket. Locate the filter in the bottom (it’s usually round and it unscrews). Remove it by turning it counterclockwise, and then rinse it under a faucet of water. Brush away any caked-on material.
Check for water or gunk in the sump (the area below the filter). Sweep out any crud with a sponge or towel. Replace the filter and attempt a short cycle to try. The majority of users, including iFixit forums users, report that a plugged filter is most often the sole cause of Error 20.
Step 3: Inspect the Drain Hose
Shut off the dishwasher for safety purposes. Locate the drain hose (typically under the sink and connected to the garbage disposal or siphon trap). Inspect for kinking or bending. Straighten if needed. Disconnect the hose and check for blockages. Flush with water or a soft-bristled brush to clear debris.
Verify the hose height: a minimum of 32 inches off the floor and secured to a drain outlet 40-85 cm high. Reinstall and check the dishwasher. Just Answer professional reported a clogged hose is an easy do-it-yourself fix, avoiding paying for a technician.
Step 4: Check the Drain Pump
Open the pump by removing the kick plate or side panel of your dishwasher (check your manual for model-specific directions). Remove wires from the pump (after unplugging the machine) and pull it away from the hoses. Check the impeller for any obstructions like hair or food bits.
Clean it out thoroughly. Check resistance of the pump with a multimeter (should read about 200 ohms). Replace with an exact part if faulty. Put back and attempt a cycle. Fred’s Appliance understands clogged or faulty pump is among the mechanical mistakes that go hand in hand with Error 20.
Step 5: Inspect the Pressure Switch
Pressure switch will be close to the pump or sump and connected with a small tube. Take out the tube and blow out the tube to clear any obstructions. Some suggest soaking in hot water and dissolved dishwasher tablet. Check the switch for damage.
Replace if damaged (use a multimeter). Plug everything back in and try again. A member on Elektroda.com cleaned out a plugged-up pressure switch tube and fixed their Error 20 after other repairs didn’t work.
Step 6: Call a Professional
In the event that nothing else works, the issue could be in the control board or a sneaky leak. Leave it to Electrolux service or a trained service technician to conduct the complicated diagnostics.
Preventative Maintenance Advice
In order to keep Error 20 from occurring, follow these rituals:
Clean the Filter Every Other Week: Clean it every two weeks to keep it from getting clogged. Scrape Dishes: Remove large chunks of food before loading to prevent filter stress. Run a Cleaning Cycle: Run a monthly dishwasher cleaner to degrease and dissolve limescale. Check Hoses: Inspect the drain hose during routine maintenance for wear or kinking.
Real User Experiences
iFixit and JustAnswer forums suggest that Error 20 is a typical failure on Electrolux dishwashers. One diagnosed it after clearing a grease blockage in a filter, and the other discovered a sock stuck in the pump. The incidents demonstrate the importance of making the right checks.
When to Replace Parts
If a cleanout won’t resolve the problem, you may be forced to replace the pump ($50-$100) or pressure switch ($30-$60). These parts are available from Electrolux or third-party companies like Parts Town UK. Replace only OEM components for compatibility.
Conclusion
Error 20 on your Electrolux dishwasher doesn’t have to spell disaster. By understanding its causes clogs, pump issues, or sensor faults you can tackle it with confidence. Start with simple fixes like resetting and cleaning, then escalate to pump or switch repairs if needed.
With regular maintenance, you’ll keep your dishwasher running smoothly and avoid this pesky error. If you’re stuck, don’t hesitate to seek professional help. Your kitchen peace is worth it!
