Hi all got a problem got the above d/w and the top arm is not working, checked for blockage none it has a button for top only spray arm that works but not working in any other program any ideas :eeek:
Usually it’s the water point that fails in the heater unit (491756). So new Heater Assy required BUT you also need to visually check the surface components on the PCB in case the heater has taken the triac out on the board, just in case. (5 min check).:wink:
