If your Whirlpool Quiet Partner II dishwasher start button flashes but nothing happens, it can be confusing. You press start, see a blinking light, but there’s no sound, no water, and no cycle.
I’ve seen this exact issue, and in most cases, it’s caused by a control lock, error state, or blocked system, not a complete failure.
Quick Answer
If your Whirlpool Quiet Partner II won’t start and start light is flashing, try:
- A quick reset
- Checking the door latch
- Cleaning the sump and drain area
Most of the time, a reset or cleaning fixes it.
Step-by-step: How to fix Whirlpool dishwasher not starting
Step 1: Perform a quick reset
This is the most effective first fix.
With the door open:
- Press Heated Dry → Normal → Heated Dry → Normal within 3 seconds
- Close the door
This should reset the dishwasher and clear errors
Step 2: Try alternative reset method (newer models)
If your buttons are different:
- Press any 3 buttons in sequence (1-2-3, 1-2-3, 1-2-3)
- Do it quickly without delay
This puts the dishwasher into diagnostic mode
Step 3: Power reset (hard reset)
If button reset fails:
- Turn off power at the breaker or unplug
- Wait 30 seconds to 1 minute
- Turn power back on
This clears deeper system errors
Step 4: Check the door latch
Dishwashers won’t start if the door isn’t properly locked.
- Close the door firmly
- Listen for a click
- Inspect latch alignment
If faulty, the control panel will just blink and not run.
Step 5: Clean the sump and filter area
A clogged system can stop the dishwasher from starting.
- Remove bottom rack
- Take out the filter and sump cover
- Clean out:
- Food debris
- Grease
- Broken glass
Blocked sump = dishwasher won’t run properly
Step 6: Check for stuck drain mode
Sometimes the dishwasher is stuck trying to drain.
- Press and hold Start/Resume for 3 seconds
- Let it drain fully
- Then restart the cycle
Step 7: Run a test cycle
After fixing:
- Select a normal wash
- Press start
- Watch if:
- Water enters
- Cycle begins
Extra tips and best practices
- Clean your dishwasher monthly
- Avoid large food particles
- Don’t interrupt cycles repeatedly
- Keep buttons dry and functional
Common mistakes to avoid
- Skipping the reset step
- Ignoring a faulty door latch
- Assuming the control board is bad immediately
- Not cleaning the sump before resetting
