Thermador Dishwasher Leaking / Aquastop Triggered

Water collecting in the base pan and tripping the anti-flood (Aquastop) float switch means the system has detected a leak somewhere in the unit. The most common cause is a failed door seal or gasket allowing water to escape during a cycle.

Checking the drain filter and water supply line is safe and often resolves simple cases — beyond that, it’s worth having a technician confirm.

If it’s leaking, turn off the water supply until it’s inspected to avoid water damage; otherwise short-term use is usually fine.

Not always — it’s often a clogged filter or hose, which the diagnostic visit determines before assuming the pump has failed.

It varies by which component is involved, confirmed in writing after the on-site diagnostic.

Once diagnosed, most are same-visit repairs.
