ASKO Washer Error Code Water inlet fault

This fault means the washer detected that insufficient water entered the machine during a program cycle. It applies specifically to the W640, W650, and W660 models. The machine stops the cycle automatically to prevent damage from running without adequate water. The cause is typically a restriction or interruption somewhere in the water supply path.

A reset may clear the fault code temporarily, but if the underlying cause is not resolved, the fault will return as soon as the machine attempts to fill again. Address the root cause, such as cleaning the inlet filter or correcting the water supply, before attempting to restart the cycle.

If the fix involves only cleaning the inlet filter or adjusting a supply valve, there is no parts cost involved. If the inlet solenoid valve needs replacement, parts typically range from $40 to $120 depending on the model year, plus labor if a technician is needed. Diagnosing the fault before ordering parts helps avoid unnecessary expenses.

Start by locating the inlet filter screen where the fill hose connects to the back of the machine, removing it, and rinsing out any debris. Also confirm the water supply valve is fully open and the hose is not kinked. If those checks pass, test water pressure at the tap and inspect the inlet solenoid valve for electrical or mechanical failure.

No, you should not attempt to run a wash cycle while this fault is active. The machine halts the program specifically to avoid operating without sufficient water, which can stress the motor, pump, and heating element. Resolve the water supply issue before resuming normal use.
