If your Bosch dishwasher gave an E01 error on the display, do not rush to panic – this is how the self-diagnosis system notifies you of a breakdown of the heating element, which you can fix yourself. You may also notice that the water in the car has stopped heating or the equipment has stopped and does not start the washing cycle.
You can find out why the Bosch dishwasher shows error E01 on the display by looking at the instructions or by reading the transcript below.
Meaning and reasons for the appearance
Fault code E 01 in the PMM indicates problems with the heating element. Perhaps its contacts are burned out, so the device does not receive a signal from the board to turn it on. Another reason is that the heater itself burned out, this happens when scale forms due to hard water.
To solve the problem, you need to check the heater. The difficulty is that in Bosch dishwashers the unit with a heating element is one-piece, with outlets for hoses and pipes. If it does not have screws for disassembly, you will have to replace the entire device.
How to fix a problem
First, make sure that the system does not generate an E1 error by chance. To do this, you need to reset the icons from the screen:
- unplug the machine from the network for 10-15 minutes;
- start PMM and look at the display.
Is the error on? Then proceed to check the heating element.
Important! A flow heater for a Bosch dishwasher costs from 3 to 000 rubles. Therefore, think carefully and make sure it is malfunctioning before you make a replacement.
What to do and how to troubleshoot:
- Disconnect the equipment from the mains, water supply and sewerage.
- Open the door and take the baskets out of the hopper.
- Remove the bottom rocker and pull out the drain filter.
- Unscrew the screws around the perimeter that hold the pipes and the heating element.
- Put the PMM upside down.
- Remove the screws and remove the back panel.
- Disconnect the wiring from the pump, turn it counterclockwise and remove.
- Put your hand under the heater block, disconnect the rubber mount.
- Disconnect the pipes and wires, then remove the heating element itself.
- Replacement is carried out in the reverse order.
Now you know why the dishwasher may show error code E01. You can fix the problem with your own hands, if you act consistently and carefully.
