Hi, I have a Teka (DW7 57 F1) dishwasher. it has started displaying an E4 error message. It first happened mid cycle and the cycle ended. now when we power it on we just get the e4 error.

This will probably mean that the tray that sits at floor level under your machine is filled with water from a leak and activated a float switch. Switch off the power, pull out the machine and tip it backwards to empty this water out of the base tray and it should work normally once you have done this.
