Fix E7 error on KTX3
E7 error KTX
Hi, The E7 code is not necessarily a sign of a product error. By this model of heating element it could happen that the square controller is not properly placed at the electric SPLIT connection.
- Disconnect the heating element from the supply.
- Unscrew the small screw at the back of the control box.
- Look inside the connection nest (deep in the round opening at the box top) – all of five metal pins should be equally deeply placed. (please take a picture of it)
- Control the same thing at the other part of the joint (the round plastic element that is protruding from the radiator’s body) – all the five pins at the same depth. (please take a picture of it)
- Now place the controller back on the radiator’s SPLIT joint – push the box firmly but gently up to the limit (the moment when your control box touches the surface of the radiator, or nearly does).
- Connect the electric supply and switch the appliance on.
- Now the heating element should start working properly.
You don't need to return the radiator. If one of the pins is knackered, we'll supply a replacement.
