Washing m/c sometimes not filling.

[just pumps]

Samsung WW7K5 fills with water on the 15/30 minute wash cycle but displays 4C error code (low/no water) on longer wash cycles.

Are there different inlet valves for different cycles and can an adjustment be made for low water pressure.

Thanks.

Many thanks for the link. I wil check the inlet pressure from the pump and the filter is clear but I am baffled why it works on a short cycle but fails to fill on a longer cycle.

Maybe the water usage is lower, so not enough time to trigger the fault?
