My m/c is 2 yrs old. 20 mins after starting a wash, the machine starts filling with more water. the prog then stop sand the start/pause button flashes. Nothing happens when you press the button. However if the programme is moved to rinse it starts - appears to drain off some water but stops again. It does this a second time. On the third occasion the prog starts and goes thru to its finish. After 4 visits from engineers it does not appear to be the PCB or the pressure switches as replacement parts have been tried but did not cure.The filter and manifold are clear. It is however suspected that there is an electrical fault with the heater as I am told it gets hot but should not. A fifth visit after the engineer has checked the wire diagrams is due shortly but I am fast losing faith.Do you think they are now on the right track by checking the heater and/or is there any other possible checks they should be doing? Thanks
