7-1
KitchenAid Dishwasher
Severity: ModerateWhat Does This Error Mean?
Error 7-1 means your KitchenAid dishwasher has detected a drainage fault — water is sitting in the bottom of the tub after the cycle ends. This is most commonly caused by a blocked filter, a clogged drain hose, or a garbage disposal knockout plug that was never removed. Most 7-1 errors can be fixed at home without a technician.

Common Causes
- Blocked or clogged drain filter at the bottom of the tub
- Kinked or clogged drain hose
- Garbage disposal knockout plug not removed during installation
- Garbage disposal or sink drain blockage backing up into the dishwasher
- Failed drain pump unable to push water out
How to Fix It
-
Cancel the current cycle and press and hold the Cancel/Drain button for 3 seconds to trigger a manual drain attempt.
This forces the pump to run and can clear a temporary blockage without any disassembly.
-
If water remains in the tub, use a towel or turkey baster to remove most of the standing water so you can access the filter.
Removing standing water makes it much easier to work and prevents splashing when you lift the filter.
-
Remove the lower dish rack and locate the circular filter assembly at the bottom centre of the tub. Turn the cylindrical filter counter-clockwise and lift it out along with the flat mesh filter beneath it.
These two filters work together — you need to clean both.
-
Rinse both filter components under hot running water and use a soft brush to scrub away food debris and grease.
A clogged filter is the single most common cause of drainage errors on KitchenAid dishwashers.
-
While the filters are out, check the drain hose at the back of the dishwasher and under the sink where it connects to the garbage disposal or sink drain. Confirm the hose is not kinked and that the disposal connection is clear.
If you have a garbage disposal, run it for 30 seconds before starting the dishwasher — a full disposal is a very common cause of dishwasher drain faults.
-
Reinstall the filters, replace the lower rack, and run a short cycle to confirm draining is restored.
If error 7-1 returns immediately after one cycle, the problem is downstream of the filter — in the hose, disposal, or pump.
When to Call a Professional
If you have cleaned the filter, cleared the drain hose, and confirmed the garbage disposal is clear but water still pools after every cycle, the drain pump has likely failed. Drain pump replacement on KitchenAid dishwashers requires removing the lower spray arm assembly and the pump housing — a job for a qualified appliance technician. Contact KitchenAid service or an authorised repair company.
Frequently Asked Questions
How often should I clean my KitchenAid dishwasher filter?
KitchenAid recommends cleaning the filter once a month under normal use. If you run the dishwasher daily or wash heavily soiled dishes, clean it every two weeks to prevent blockages.
What is the garbage disposal knockout plug and how do I know if it is blocking my drain?
When a garbage disposal is first installed, it has a plastic plug in the dishwasher drain port that must be knocked out before connecting the dishwasher hose. If this plug was not removed during installation, your dishwasher has never been able to drain properly — you will need to disconnect the drain hose and use a screwdriver to knock the plug out from inside the disposal port.
Is it safe to run my KitchenAid dishwasher with standing water in the tub?
Running the dishwasher with standing water in the tub can lead to odours and mould growth, and the dirty water will mix with the fresh wash water in the next cycle. Clear the blockage before running another cycle.
