ASKO Dryer Error Code Over flow fault

The overflow fault means the dryer detected that its condensed water collection tank was full, causing a float to rise and open a microswitch. When that microswitch stays open for more than 30 seconds after a programme starts, the dryer stops the cycle automatically. This is a protective feature designed to prevent water from spilling into the machine or onto the floor.

No, you should not continue running the dryer while the fault is active. The cycle will stop automatically after 30 seconds, and attempting to bypass or repeatedly restart without resolving the underlying cause risks water buildup inside the appliance. Address the fault before running another cycle.

If the fix is simply emptying the water tank or cleaning hoses, there is no parts cost involved. If the drainage pump needs replacement, parts and labour costs typically range from around 150 to 350 dollars depending on your location and service rates. Replacing a faulty microswitch is generally less expensive, with parts and labour often falling in the 80 to 200 dollar range.

In many cases, yes. Start by emptying the water tank completely and restarting the machine, which resolves the fault if an overfull tank was the only cause. If the error returns, check the hoses for blockages and inspect the float for debris or scale buildup that may be keeping it stuck in the raised position. If those steps do not resolve it, testing the drainage pump and microswitch requires basic electrical knowledge and a multimeter, so you may want to call a technician at that point.

A reset alone will not permanently clear the fault if the underlying condition still exists. If the water tank is still full when you restart, the microswitch will open again within 30 seconds and halt the programme again. You must empty the tank and confirm the float and drainage system are functioning correctly before the fault will stay cleared.
