Miele [F70] fault codewhat it means and how to fix it

F70 is the code for Miele’s Waterproof System, and it is the only Waterproof System article in their entire dishwasher index. Their instruction is worth reading in full because it is the best-written leak instruction of any brand covered on this site: the Waterproof System has been activated, the current programme is cancelled and the drain pump switches on, close the stopcock, switch the dishwasher off, disconnect the mains plug, the drain pump will stop running, contact Miele Customer Service. Notice what that sequence tells you. The drain pump running is not a fault developing — it is the machine actively pumping out to protect you, and Miele explain that it stops once you disconnect the power, so an owner who unplugs it and hears the noise cease knows the system worked rather than that something broke. That is a small piece of writing that prevents a lot of panic. Notice also the order: stopcock first, then power. Water is what does the damage, and it keeps arriving whether or not the appliance has electricity. Miele’s clarity here makes a useful contrast with some other brands. LG give their leak code no isolation instruction at all, and one Samsung support page suggests taping a leaking hose. Miele tell you to shut everything off and stop.
