Error E09 in a Siemens dishwasher

What does error E09 mean in a Siemens dishwasher, what should I do to get rid of it? The decoding of this code is simple – a heating element error. See below for troubleshooting.

Causes of breakage

In addition to wide functionality, Siemens dishwashers are equipped with a self-diagnosis system. As soon as a breakdown occurs in the equipment, a fault code is immediately displayed on the display. By calculating the value of the code, you can quickly find the cause of the breakdown.

Most often, the E9 code appears in dishwashers with a flow heater that is built into the circulation pump. Why does the system show an error? Because the wiring was broken or the heater itself burned out. What could have happened:

1. Water got into the heating element through a worn seal, a short circuit occurred.
2. A blockage in the drain filter provoked a slow outflow of water, which caused overheating and combustion of the element.
3. Scale. Wrong choice of salt or its absence in the ion exchanger led to the formation of scale and overheating.

How to fix the situation? Replacing the heater will help.

Stages of repair work on the replacement of heating elements

Before proceeding with the repair, try resetting the E09 code: the machine may be giving an error as a result of a system failure.

Disconnect the PMM from the network for 10-15 minutes. Then turn it on again and look at the scoreboard. Are the icons gone? If the display is lit again, then read on.

What you need to replace:

• screwdriver;
• multimeter;
• new heater.

Since the heating element is part of the circulation unit, you will have to remove it. Proceed in sequence:

1. Disconnect the machine from communications and electrical network.
2. Remove the front part (if the PMM is of a built-in type).
3. Remove the screws and remove the bottom panel under the door.
4. Remove the thermal insulation and unscrew the pallet bolts.
5. Remove the dish baskets from the hopper.
6. Remove the lower rocker, pull out the drain filter – behind it is the pump cover. Unscrew the screws securing it.
7. Turn the Siemens dishwasher over on the back wall.
8. Disconnect the pump from the circulation pump by turning it counterclockwise.
9. Release the block from the wires and remove from the mounts.
10. Loosen the clamp holding the heater, disconnect its wiring.
11. Install a new item.

Important! Use only original spare parts for replacement.

Assemble the car in reverse order. Recommended taking care of your dishwasher Siemens to avoid problems with the heater and other parts.
