F11: Drainage Fault
F11 appears when the dishwasher cannot pump water out within the expected time. Start with the filter at the base of the tub, which collects food and grease. Then check the drain hose for kinks, the drain pump for debris, and, if the machine drains through the sink plumbing, the air gap or disposal connection. In many homes clearing the filter and hose resolves F11 outright. If the pump itself has failed, it needs replacement.
F70: Float and Water Level
F70 relates to the float or water-level sensing system. A common trigger is water pooling in the base pan from a small leak, which lifts the anti-flood float and shuts the machine down to protect your floor. Turn off the water, dry the base if you can reach it, and watch for a return. If F70 comes back once the base is dry, either the float switch has failed or there is a leak that needs to be found, both of which call for a technician.
F14: Heating Circuit
F14 points to the heating circuit on many Miele dishwashers, meaning the water is not reaching temperature as expected. Because dishes rely on hot water to clean and dry, you will notice poor results alongside the code. This is not an owner fix; the heating components and their wiring need to be tested, so book a diagnosis.
