Common Symptoms & Causes

If your Asko DBI564IS is having trouble draining, you might notice one or more of these symptoms:

• The dishwasher display shows the E3 error code during or after a wash cycle
• Standing water remains at the bottom of the dishwasher tub after the cycle ends
• The dishwasher stops mid-cycle and fails to drain
• You hear the drain pump humming but no water is being expelled

These issues are usually caused by a blocked or clogged drain filter, a kinked drain hose, a failed drain pump, or debris obstructing the pump impeller — all of which prevent water from exiting the machine effectively.

Safety First

• Unplug the dishwasher from the power outlet before starting any repair — never work on a live appliance.
• Shut off the water supply valve before disconnecting any water lines or hoses.
• Wear work gloves when handling metal brackets, sheet metal edges, or sharp components.
• Take photos with your phone before disconnecting any wiring harnesses or connectors.
• Work in a well-lit area with enough floor space to lay removed panels flat.

Step-by-Step Repair Instructions

Step 1

Start by disconnecting the dishwasher from power to eliminate any risk of shock. Pull out the lower rack to access the Asko 3-piece filter assembly (coarse filter, fine filter, and microfilter). Remove all three filter components — a clogged filter is the most common culprit behind E3 errors, as restricted flow triggers the pump fault before the water can drain. Rinse each filter under running water until clear, and inspect the sump area beneath the filters for broken glass or debris that could damage the pump impeller.

Step 2

Locate the drain hose exiting the rear of the unit and trace its entire length, checking for kinks that would block flow regardless of pump function. If the drain hose connects to a garbage disposal, verify that the factory knockout plug inside the disposal inlet has been removed — a missed knockout plug is a frequent installation error that completely obstructs drainage. A properly routed hose should have a high loop or air gap to prevent backflow, which can also trigger drain faults.

Step 3

Tilt the unit backward to access the drain pump at the lower rear of the sump, then disconnect the pump harness and test resistance across the pump terminals using a multimeter set to Rx1. A healthy pump should read approximately 300Ω, while an open reading (OL) indicates a failed motor that will need replacement. Also, check the impeller by spinning it by hand through the pump housing; it should turn freely. If it’s seized, debris is likely lodged inside, which could burn out the pump if power is restored. Pro tip: wear gloves when reaching into the sump, as broken glass often accumulates there.

Step 4

Before replacing the pump, remove the drain hose from the pump outlet by loosening the hose clamp with a 5/16″ nut driver, then disconnect the wiring harness. Rotate the pump body a quarter-turn counter-clockwise to unlock it from the sump bayonet mount and lift it free — this twist-lock design means no screws are needed, although some resistance is normal if the rubber seals have seated tightly. Install the new Asko drain pump by seating it and rotating clockwise until it locks in place, then reattach the hose and harness, ensuring the clamp is snug to prevent leaks under pump pressure.

Step 5

Reinstall the three filter components in reverse order — microfilter first, then fine, and then coarse — ensuring the coarse filter locks flat. A misaligned filter can allow debris to reach the pump and cause repeat failures. Slide the lower rack back in, carefully return the unit to upright, and reconnect power. Pro tip: place a towel under the front of the unit before running a test cycle in case any hose connection was not fully seated.

Step 6

Run the dishwasher’s dedicated Drain program to force the control board to activate the drain pump immediately without running a full wash cycle. The E3 error will clear automatically once the control board detects that the pump has successfully emptied the tub — if E3 returns within the first minute, recheck the hose connection at the pump outlet and verify that the harness connector clicked into place.

When to Call a Professional

If the issue persists after completing all the steps above, the problem may involve a failed main control board, a seized circulation or drain pump, or wiring that requires specialized diagnostic equipment. At this point, it’s best to contact a licensed appliance technician — and don’t forget to shut off the water supply valve before any work that opens the fill or drain circuit.

How Much Does This Repair Cost?

DIY parts for fixing the E3 drainage error on an Asko DBI564IS typically cost between $10–$75, depending on whether you need a new drain pump, filter, or hose. A professional service call for the same repair generally runs $150–$300 including labor. Tackling this yourself can save you $100 or more.

Frequently Asked Questions

What does the E3 error code mean on my Asko DBI564IS?

The E3 error indicates that your dishwasher is unable to drain water within the expected time. This is typically caused by a clogged filter, blocked drain hose, or a faulty drain pump.

Can I fix the E3 error myself without calling a technician?

Absolutely! Many E3 errors can be resolved by cleaning the filter and checking the drain hose for kinks or blockages. If the pump is faulty, however, you may need a professional repair.

How do I reset the E3 error after fixing the drainage issue?

Once the blockage is cleared, turn the dishwasher off, wait 30 seconds, and power it back on. The error should clear automatically when the unit successfully completes a drain cycle.

The Drain Pump That Actually Stops the E3 Error on Your Asko DBI564IS

If you’ve cleared the filter and the E3 error persists, the drain pump itself has likely failed—and this is the OEM part that gets you back to normal without hunting for a universal aftermarket substitute that may not seat properly.

What works

• Direct fit into the Asko DBI564IS mounting bracket—no adapter fumbling or forcing connections that don’t align.
• The impeller design matches the original flow path, so you don’t get partial drainage or slow drains that mask a larger electrical fault.
• Comes with the correct connector clips, so you’re not rewiring or improvising connections that could short out your control board.

What doesn’t

• If your error is actually a kinked drain hose or a blockage in the standpipe, swapping the pump is wasted money—test the hose first with a straightened wire.
• Installation requires draining the tub and removing the lower rack and filter housing, which means this isn’t a 15-minute fix if you’re new to the model.

I’ve had customers order a generic drain pump first and waste a week returning it when the part didn’t click into the connector—OEM beats guessing every time. Asko DBI564IS drain pump 8084454 replacement
