Frequently Asked Questions

What does error code F18 mean on an Asko dishwasher?
Error code F18 indicates that the detergent dispenser is stuck and not opening during the wash cycle. This prevents detergent from being released into the wash water.
Can I run my Asko dishwasher with error F18?
It is not recommended. The error will likely prevent the cycle from completing properly. Try fixing the dispenser first, or the dishwasher may not clean dishes effectively.
How do I reset the Asko dishwasher after fixing error F18?
After clearing the obstruction, plug the dishwasher back in. The error should clear automatically. If not, try pressing the Start/Reset button for 3 seconds or power cycle the dishwasher.
Why does my Asko dishwasher dispenser keep getting stuck?
Common causes include using too much detergent, using the wrong type (e.g., non-dishwasher detergent), or allowing detergent to clump due to moisture. Always use fresh, recommended detergent and avoid overfilling.
Do I need to replace the dispenser if it's stuck?
Not always. Often, a simple cleaning and removal of debris will fix it. If the actuator mechanism is broken or the flap is damaged, replacement may be necessary.
