Repair Guide

How to Fix Error AE

1

Identify the leak location

Run a short cycle and watch where water appears. Front = door seal. Underneath = hose or pump. Back = supply line.
2

Check the door seal

Run your finger along the entire door gasket. Feel for tears, hard/brittle spots, or gaps. Clean the seal with soapy water and a cloth — buildup prevents a good seal.
3

Inspect hose connections

Unplug the appliance and look at every hose connection underneath. Tighten any loose clamps. Look for drips or mineral deposits (white crusty buildup) at connection points.
4

Check for proper loading

Make sure spray arms can spin freely and nothing is blocking them from turning. Overloaded racks deflect water in unintended directions.
5

Inspect the tub/sump

Look inside the bottom of the tub with a flashlight for cracks. Check the sump area underneath the appliance.
6

Replace the door gasket or tighten fittings

Door gaskets usually just press-fit into a channel around the door. Hose clamps can be tightened with pliers or a screwdriver.
