Hotpoint Dishwasher Error Code AL03

AL03 means the dishwasher failed to drain within the maximum time allowed. The control board monitors a pressure switch to confirm the sump is empty, and when that confirmation does not arrive in time, the AL03 fault is logged. The most common causes include a blocked drain pump, a restricted drain hose, a wiring fault at the pump connector, or a failed drain pump motor.

A reset may temporarily clear the AL03 code, but the fault will return if the underlying cause has not been addressed. Resetting is useful to confirm whether the issue was a one-time event such as a temporary blockage, but persistent AL03 errors require a physical inspection and repair of the drain system before the dishwasher will operate reliably.

If the cause is a simple blockage or a loose connector, the repair may cost nothing beyond your time. If the drain pump needs to be replaced, parts and labor typically range from around $80 to $200 depending on your location and the service provider. Getting a diagnostic estimate before committing to a repair is recommended.

Start by removing the filter assembly at the bottom of the dishwasher and checking for any debris blocking the drain pump impeller. Next, inspect the drain hose for kinks or blockages and confirm it is routed correctly. If those checks are clear, examine the pump's electrical connector for loose or corroded contacts. If the pump receives power but still does not drain, the pump itself likely needs to be replaced.

You should not run the dishwasher while AL03 is active. Because water is not draining correctly, continued use risks leaving standing water in the sump, which can lead to leaks, odors, or water damage inside the unit. Resolve the drain fault before running another cycle.
