A Fault message E09 lighting on your dishwasher`s display is the third most common error code in Bosch dishwashers (after E15 and E24) that our customers contact our company with. It lights up on the dishwasher display immediately after starting or at the beginning of the washing cycle, about 10 minutes after start.
If you look inside a Bosch dishwasher that has drawn water and stopped with code E09, you will find that the water is cold, it has not heated up. However, in pre-rinse mode, when no heating is required, the dishwasher can function normally: no error occurs.
Error code value E 09 indicates a problem with the heating element. Error E09 in dishwashers of the famous brand informs about the breakdown of the heating element. It means that your it is defective. The flow heater in the dishwasher is different from the heating element in the washing machine. It attaches to the recirculation pump for efficient water heating.

In this case, the earlier the better to call North Country Appliance Repair Company and schedule an appointment.
Causes of appearance:
Why did the heater burn out? This question is asked by many users who find themselves in such a situation, and rightly so. It is necessary to know the causes that led to this malfunction in order to further reduce the risks of its occurrence. Although each part has its own lifespan, and no matter how you maintain, they wear out. Nevertheless, let’s list all the causes:
Water ingress on the heater. Water can get on the heater, through the appeared places of leaks. Most often this place is the sealing rubber, which lies between the machine body and the filter cup.
Clogs in the drain filter. Because of clogs, water is slow to flow into the tank and the heater overheats. Overheating causes rapid wear and tear.
Hard water and scale. If there is not enough salt in the ion exchanger, the water remains hard. When heating such water, scale forms on the heating element, over time, the scale leads to prolonged heating of water and failure of the heater.
