If you see the E13 Error code on the display of your device, this means that the water, your Bosch dishwasher is supplied with, is too hot. In other words, if the temperature of the water, running into the machine, if higher than 75 C, the E13 combination will the displayed.
What can cause the E13 Error?
Besides the most logical explanation for this error — the connection of the appliance to the hot water, there is one more thing that can cause it. The malfunction of the sensor, responsible for detecting the water’s temperature, which sends wrong signals to the main unit.
How to fix the E13 Error?
First of all, let’s exclude the system glitch for the list of probable reasons for the E13 Error. Reboot your device, giving it 15 minutes to rest. If you don’t see the code after switching the machine back on — lucky you! Now you can start the washing cycle and stop worrying. But if the code is still indicated on the display, you need to check the temperature-sensor and, probably, connect your machine to the cold water tap.
When inspecting the detector, pay attention to its contacts, as they can be burnt out or oxidized. So clean and replace the ones that need it. If the wires are fine, check the detector itself with the multimeter and replace the whole element if it is out of order. If this didn’t solve the problem, there is a radical solution — connecting the appliance to the cold water, instead of hot.
There are actually many advantages of the cold water — it is softer, has less dirt in it, doesn’t damage the systems of your machine, and doesn’t clog the pumps and filters. Besides, the powder and soap you use for your device, work better with the water that heats deliberately, than with the instantly hot.
