Miele Dishwashers - Recent Questions, Troubleshooting & Support

f24 is no signal from the heater relay. at the start of a cycle the dishwasher runs the drain pump for 30 seconds. it will, at the same time send a power signal to the heater relay. if the computer doesnt see a signal back from the relay, it will stop the cycle and beep. Sometimes this happens almost as soon as you press the start button. Sometimes the relays are just bad, but it is usually caused by a voltage spike, or by using too much detergent. the excess detergent will oversuds the machine, and leak into the bottom pan. the soap will corrode the contacts on the relay and cause the f24 fault. the relay can be accessed by removing the bottom pan of the dishwasher with 4 t20 screws. it requires that the dishwasher be turned on its side.

I had the same problem a few days ago. I followed the instructions to clean the filter and check to see that the impeller was free to rotate in both directions. The problem persisted. After reading this thread, and a similar one on another site, I tried what mikeboerma suggested in "solution #3", and bingo, problem solved. The magic combination is to push and hold the on/off button and the start/stop button.

I had this happen when my "water pump" went out on my dishwasher. It wasn't pumping the water up and into the machine or pumping it out.
