What Does Error Code F14 Mean on a Miele Dishwasher?

Heater pressure switch fault.

F14 fires when the control cannot confirm a valid signal from the heater pressure switch, the safety device that verifies water is circulating past the heating element before it energizes. Without that confirmation the board halts to prevent dry-firing the heater. Typical triggers are a failed switch, a blocked or split pressure hose, or debris restricting the sump and circulation path. Unlike broader heating or flow faults, F14 points specifically at the pressure-confirmation signal rather than the element or drain itself.

Models affected: Miele dishwashers with a heater pressure-switch safety circuit, including recent G-series models such as the G 7000 Series

What owners report: Owners commonly report F14 appearing mid-cycle when the water should be heating, sometimes leaving dishes wet or cold. A clogged filter or trapped water in the pressure hose can falsely trigger it, and many find that cleaning the filters and sump before restarting on a short program clears the fault.

Can I keep using my Miele Dishwasher when error F14 appears? +

A reset only clears the stored F14 fault; if it returns, the heating problem is still present.

This is a moderate job — a multimeter and some disassembly are usually involved.
