On many KitchenAid dishwashers, a flashing Clean light is the control reporting a fault code in two groups of blinks: a function number, then an error number. Writing that pattern down is the most useful thing you can do, and this path covers what to check before you call.
Safety first: Switch off the breaker or unplug the dishwasher before you clean the filter or look at the connections under the sink.
Follow the diagnostic path
Step 1: Does the Clean light blink in two groups, with a short pause between them and a longer pause before it repeats?
If yes: Count both groups. KitchenAid's own help pages describe the first group as the function (F) number and the second as the error (E) number, so seven blinks, a pause and one blink reads as F7 E1. Write it down. What each code means varies by model, so give the exact pattern and your model number to the technician.
If no: Go to Step 2.
Step 2: Are other lights flashing too, or all of them at once?
If yes: Note exactly which lights flash and how. A different light, or all lights, can mean something other than a Clean-light code, and that detail helps the diagnosis.
If no: Go to Step 3.
Step 3: Did the flashing start after a cycle left water in the bottom?
If yes: Drainage may be involved. Clean the filter, check the drain hose under the sink for kinks, and make sure the disposal inlet is clear.
If no: Go to Step 4.
Step 4: After cutting power at the breaker for a minute, does the next cycle run normally?
If yes: It may have been a one-time fault. If the flashing returns, book a technician and pass along the code.
If no: Go to Step 5.
Step 5: Can you hear water entering at the start of a cycle?
If yes: Supply looks fine; the fault is elsewhere, and a technician should run the diagnostics.
If no: Check that the supply valve under the sink is fully open. If it is, an inlet valve problem is possible. If the dishwasher won't respond at all, our guide to a dishwasher that won't start covers the basics.
What your answer points to
| What you found | Most likely cause | DIY or technician |
|---|---|---|
| Two-part blink pattern | Fault code (F and E numbers) | Technician, with the code |
| Several lights flashing | A different alert or code | Technician |
| Water left in the tub | Drain blockage | DIY filter and hose check |
| Clears after power reset | One-time fault | DIY; technician if it repeats |
| No water entering | Closed valve or inlet fault | DIY valve check, then technician |
Stop and call a technician if
- •The same pattern comes back after a reset.
- •You see water on the floor or smell burning.
- •The dishwasher won't respond to any button.
Keep it from coming back
- •Clean the filter regularly.
- •Keep the drain hose routed with a high loop or air gap.
- •Note any code the day it shows up, even if it clears.
Owen's shop tip: Film the flashing on your phone. Counting fast blinks is hard, and a short video gives the technician the exact code.
