A dishwasher can collect food debris and residue even when it runs regularly. Begin with the parts the manual says you can maintain, then use an approved cleaning product or method. This is routine cleaning, not a fix for standing water, leaks, or a mechanical fault.
Empty the dishwasher, clear accessible debris, clean a removable filter only as directed, reinstall it correctly, and run the approved cleaning cycle.
Go straight to the stepsBefore you begin
Let the machine cool and follow the manual’s safety directions before reaching inside. Watch for broken glass; do not feel blindly around the sump.
What you’ll need
- The dishwasher’s use-and-care guide
- A compatible dishwasher cleaner
- A soft cloth or brush approved for the filter

Let’s do this
Step by step
- 01
Check the model instructions
Find the model number and manual, then identify whether the filter is user-removable. Note how its parts unlock and lock before taking them out. A photo of the assembled filter can help you put it back correctly.
- 02
Remove visible loose debris
Empty the racks as needed for access. Carefully remove visible food pieces or other debris without pushing material deeper into the machine.
- 03
Clean an accessible filter
For a user-removable filter, follow the manual’s release method and rinse under running water. Use a soft brush only if allowed; avoid wire brushes and scouring pads that damage mesh. Refit every filter part and check that it locks correctly. Do not run the dishwasher with a loose or missing filter.
Rinse only a user-removable filter. Your model’s manual shows how to release it and lock it back in place.Open full-size image - 04
Run the approved cleaner
Follow the cleaner’s exact dose, placement, and cycle instructions. Keep this routine simple by using an empty machine, unless the selected product explicitly specifies otherwise.
- 05
Check the result
After the cycle, inspect the interior and accessible door edges. Follow the manual for wiping any remaining residue and cleaning the exterior finish.

Use the product’s instructions, not a guessed dose
Dishwasher cleaners differ in where they go and whether they are used with dishes. Instructions for one tablet are not universal instructions for every product. Keep the packaging until the cleaning cycle is complete.
Do not add hand dishwashing liquid to the machine. For routine maintenance, choose a method approved by the appliance maker and avoid combining multiple cleaners. A longer ingredient list does not make the process more effective.
When a second cleaning cycle is not the answer
If there is standing water, a leak, or repeated poor drainage, investigate that symptom rather than repeatedly running cleaning cycles. Make a note of the error code and when the problem appears. That gives the manufacturer or repair technician a much better starting point.
A quick final check
- Any removable filter is correctly reinstalled.
- The chosen product and cycle match the instructions.
- Persistent drainage or leak symptoms are treated separately.
Common questions & sticking points
How often should I clean the dishwasher?
Whirlpool suggests regular debris removal and a monthly deeper clean. Follow your own model’s schedule and adjust for its use and water conditions.
Can I remove every dishwasher filter?
No. Locate the model’s filter instructions first. A part that does not release as described should not be forced. Once a removable filter is clean, reinstall and lock it according to the manual before starting the machine.
