Miele Dishwasher Error Code F82 — Water Leak Detected (AquaStop Triggered)
What this means
The F82 error code on Miele dishwashers means the AquaStop float switch in the base pan has been triggered by water accumulation. Miele dishwashers have a sealed base pan with a float switch that detects leaks early. Water in the base can come from a leaking hose connection, a damaged spray arm seal, a cracked sump, a faulty door seal, or condensation buildup.
Alternate codes: F 82
Step-by-step fix
4 stepsTurn off the water and power
Close the water supply valve under the sink. Turn off the circuit breaker for the dishwasher. Place towels around the base to catch any water that may drain out.
Respond to this error promptly to minimize potential water damage to your floor and cabinets.
Tilt the dishwasher to drain the base pan
Pull the dishwasher partially out and tilt it slightly backward (about 15 degrees) to allow water in the base pan to flow toward the rear and into a towel or tray. Some models have a small drain at the rear for this purpose.
Have a helper hold the dishwasher while you tilt it. Be careful not to stress the water supply and drain hose connections.
Identify the leak source
With the dishwasher pulled forward, remove the lower kick panel and use a flashlight to inspect the underside. Look for drips at hose clamp connections, the door seal bottom, the sump area, and the inlet valve. Run a short cycle with the panels off to observe where water appears.
A common Miele leak point is the spray arm bearing seal. If water pools directly under the center of the tub, check this seal.
Fix the leak and dry the base pan
Tighten any loose hose clamps, replace a damaged door gasket, or replace the leaking component. Thoroughly dry the base pan and the float switch area with towels. Once dry, the float switch will drop and the error should clear.
If the float switch itself is stuck in the up position due to mineral deposits, clean it carefully to ensure it moves freely.
When to call a professional
If you cannot identify the leak source, or if the sump housing or internal hoses are cracked, a Miele-certified technician can perform a comprehensive leak test.
