I am new here, but I have a vokera boiler that keeps flashing a D1 error code, engineer took the pipe out of the boiler itself and cleaned it, it was full of black dirt. Was working ok but now the D1 code is flashing again, I leave the boiler off, turn to reset and it works again, however on start up it flashes again D1 code. Engineer is coming this week to change the sensor and trap.
How come it works once reset? is this a sensor/trap fault or is it electrical? We have tested the pipe that goes into the waste pipe under the sink and the condensation is draining away just fine.
Any ideas?
