Bosch dishwasher error code E27

If you notice the E27 Error code on the control board of your Bosch dishwashing appliance, it means your machine is trying to tell you that not everything is right with the voltage in your mains. This code usually appears in the evening, when everybody comes home and switches too many electric appliances on. The network gets overloaded and the machine indicates an error.

What can cause the E27 Error?

Besides the overloaded power network, the list of causes for this error appears on the screen of your device may include the one-time malfunction of the control board and the issues with wiring connection between your appliance and the main power socket.

How to fix the E27 Error?

First of all, there is a way to avoid the occurrence of the E27 Error — simply select the delayed cycle start when you come back home from work. Choose the H03 or H04 regimen, so that your dishwasher will start working in 3-4 hours after the network-peak.

Another thing to do amongst the first ones — rebooting your device, in order to eliminate the system glitch from the list of possible error causes. Switch the appliance off and unplug it from the main power, let it rest for 10-15 minutes and switch it back. If you still see the E27 code on the display, this means that the problem is in the power supply and you have to fix it in order to be able to use your dishwasher.

The best way to deal with it to install a stabilizer. There are two possible types of it: a compensating one and a wide-band. The compensating regulator is easy to install and use. As it is clear from its name, this stabilizer compensates and balances the power in your main. As for the wide-band regulator, it works both on the high and low voltages. This type requires professional installation and is pretty loud while working.

There is also a third type of regulators — the main one, which is being installed on the mains of the whole building, so if you live in the apartment, it will not be easy to do. But this stabilizer protects all your appliances and lets you use them all without any risk of network problems.
