Answer to continue safely
Is it safe to keep using?
No. The machine will not run while F8 is active, as it is a safety interlock. The door must be confirmed as closed before the cycle can start or continue.
Can I reset the code?
Yes. A power cycle resets F8. If the door latch is simply not closing fully, the fault clears immediately when the door is properly latched. A failed switch will return F8 on every start attempt.
When to stop immediately?
Stop if you notice: The door does not stay closed without being held, indicating a failed latch or hinge, F8 appears on every start attempt even with an empty machine and the door pushed firmly shut.
Symptoms You May Notice
Dishwasher will not start and F8 is shown when Start is pressed
The cycle cannot begin because the control board has not received a door-closed confirmation signal; pressing Start simply re-displays F8.
Cycle stops suddenly mid-wash and F8 appears
A basket item protruding against the door, or a weakening latch spring, allows the door to pop slightly ajar during vibration, triggering the fault mid-cycle.
The door does not latch with a firm click
Attempting to close the door produces a soft or absent click, and the door swings back open slightly, confirming the latch mechanism is worn or the strike is misaligned.
Door appears closed but F8 still shows on the display
The latch appears to engage visually, but the internal door microswitch has failed and is not sending the closed signal to the controller.
Possible Causes
Overloaded baskets preventing full door closure
Items in the basket are taller than the basket edge and press against the inside of the door, preventing the latch from reaching the strike with enough force to engage.
DIY PossibleWorn or broken door latch mechanism
The plastic latch hook or strike has cracked or worn down, preventing the latch from securing properly even when the door is pushed firmly closed.
DIY PossibleFailed door microswitch
The microswitch inside the door panel that signals a closed and latched door has failed open-circuit and cannot send the confirmation signal to the control board.
Requires ProfessionalSafe Checks You Can Do
-
1
Check basket loading and reclose the door
Open the door and inspect both baskets. Ensure no utensils, bowl rims, or pan handles protrude beyond the basket edge into the door path. Reposition any items and close the door firmly with both hands until you hear a distinct click. Press Start immediately.
Tall glasses and mixing bowls in the top basket are the most common culprits — always ensure they clear the door interior panel.

2
Inspect the door latch strike
With the door open, examine the plastic or metal latch strike on the front of the tub frame. Look for cracks, chips, or rotation out of alignment. If the strike is held by a screw, check it is tight. On some Asko models the strike can be gently rotated to the optimal engagement position.
A correctly aligned strike should have the hook perpendicular to the door, positioned to catch the latch tongue cleanly.

Reset and test
Turn the dishwasher off at the power button, wait 10 seconds, then turn it back on. Close the door firmly and select a program. If the Start button lights up and the cycle begins without displaying F8, the latch was the issue.
If F8 returns even with an empty machine where nothing can obstruct the door, the latch or switch needs repair.
When to Call a Professional
Contact a qualified technician if:
- Door microswitch shows open-circuit when tested with a multimeter in the closed/latched position
- The latch hook or strike is visibly cracked and cannot be adjusted or repositioned
- The door is visibly misaligned (dropping at one side), indicating hinge wear requiring adjustment
