The machine won’t stop filling with water. I have confirmed that blowing into the pressure transducer does stop the water flow. I have checked the tube and there appears to be no blockages or splits. So maybe I am up for a new Motor Control Module ?
Fortunately didn’t get an overflow as the filter was almost blocked and water flow was only a trickle. Which raises another question – when filling should the blue insert allow water to come from the large round hole at the end or just from the smaller rows of holes ? I am wondering if the cold water valve also might be partially stuck and unable to open fully.
Beware the damage caused by earthquakes to a houses mains water supply.
