Hi. I have an Indesit WIDL 126 S washer dryer which is about 6 months old now. Since first owned the washer would sometimes stop mid cycle and flash the following ligths 3 and 4 along with the red door lock swich. The manual suggests switching off for 40 seconds at the mains and then retrying. This usualy works and the washer/dryer works again for a while. Lately however it is becomming more frequent and stops on nearly every full cycle. Switching off will alow the washer to be used again but its 50/50 wether it will finish OK or not without another power off. Does anyone know what the error means ?. Thanks
