Miele dishwasher F70 error code
F70 means waterproof system triggered. Water was detected in the base pan, so the waterproof system shut the machine down..
Often fixable at home · Fault type: Electrical/hardware
Safe checks, in order of likelihood
- Pull the machine out and check underneath for standing water.
- Check the door seal and hose connections for weeping.
- Do not keep running the machine — it will keep tripping until the leak is fixed.
Call a professional when…
Find and fix the leak (seal, hose or clamp); the system then stops triggering. If the code returns after these checks, book a qualified engineer.
Parts usually involved
- Door seal / hose clips as required.
