The machine failed to work and just emitted a whining type noise. On investigation it appears that this is due to it not filling with water. I have checked the supply pipe and filters which seem to be in order. Next I disconnected the machine and removed the side panels to look for anything obvious and have found that at the bottom of the plastic matrix there is what appears to be a reservoir, with min/max lines, which contained a brown/coca cola coloured liquid. I was surprised at the colour of this as up to now its been working fine.
Does anyone know if this brown liquid is normal and suggest a fix?
Thank you, Mark
